  Bladder health is important for people who often face urinary problems. A portable bladder scanner is a very helpful tool that gives quick pictures of the bladder. It helps doctors check and monitor to treat bladder problems. Now, there are so many options to choose from. So, how do you know which one is right for you? This guide will help you understand six important things to consider before buying a portable bladder scanner. With this, you can help make the best choice.

1. Highly Accurate Measurements

Accuracy is very important when you look for a bladder scanner as a healthcare professional. You want a model that gives you correct measurements for all different bladder sizes. These accurate readings help you find problems like urinary retention and bladder issues without any catheter.   You need to look for scanners that are very accurate even with small amounts of urine. The best ones can measure between 20ml to 99ml with a ± 15ml accuracy. This helps you catch even small changes in bladder size. This is important for patients with smaller bladders.   Accuracy can be a bit different for large amounts of urine. A good portable bladder scanner should measure between 100ml and 999ml with a ± 15% accuracy. This helps you monitor patients of all ages with many different bladder sizes. (more…)
Complementary Medicine, Prostate, Supplements / 23.09.2024

Editor's note:  This article discusses supplements, which in no way are intended to substitute for professional medical care and regular prostate cancer screening.  Supplements are generally not FDA tested or approved. Some supplements can interfere with medications and/or cause side effects. Do not delay seeking medical attention for prostate concerns by taking supplements without medical advice. Please discuss any and all supplements you take with your health care provider and be sure to follow your provider's recommendations for your prostate and overall health. As men age, maintaining good prostate health becomes a top priority. The prostate, a small gland located below the bladder, plays a significant role in male reproductive health. However, many men face challenges related to this vital organ, especially as they get older. Fortunately, natural supplements can help support prostate health and overall well-being. In this article, we'll explore the benefits of these supplements, how they work, and how you can incorporate them into your lifestyle. Before we begin, it's essential to remember that supplements like Prostovit are among many that can help, but they should always be used as part of a holistic approach to health.   Prostate gland supplements

Why Prostate Health is Important

The prostate is crucial for producing seminal fluid, which helps transport sperm during ejaculation. Over time, the prostate may enlarge, leading to conditions like benign prostatic hyperplasia (BPH), or even develop into more severe conditions like prostate cancer. Prostate health directly impacts urinary function and quality of life, making it a critical aspect of men’s health that shouldn’t be ignored. Symptoms such as frequent urination, especially at night, difficulty starting or stopping urination, and weak urine flow are common indicators of prostate issues. Addressing these symptoms early with lifestyle changes and natural supplements may prevent more serious complications in the future. (more…)

MedicalResearch.com Interview with: Paul Piedras, BS University of California, Irvin MedicalResearch.com: What is the background for this study? Response: The consumption of alkaline water is gaining popularity among the public as a preferred method of hydration.  A variety of reasons may be associated with this including that the general population may believe that drinking an alkalotic fluid will lead to a raise in systemic pH. Given that alkaline water is more expensive than spring water, we decided to further explore what effects it may have on urinary alkalization. (more…)

MedicalResearch.com Interview with: Michael Bailey Ph.D. Senior Principal Engineer, Applied Physics Laboratory Associate Professor. Mechanical Engineering Adjunct Associate Professor Urology MedicalResearch.com: What is the background for this study? Response: Small (< 6 mm) kidney stones are common and often are asymptomatic. Do you do surgery or wait for them to cause a problem? Or specifically here if you are getting surgery already for other stones that are causing a problem do you take the time and possibly extra risk of cleaning out the small stone in the kidney or in the other kidney?

MedicalResearch.com Interview with: Lin Yang, PhD Research Scientist/Epidemiologist Department of Cancer Epidemiology and Prevention Research Cancer Care Alberta | Alberta Health Services | Canada Adjunct Assistant Professor Departments of Oncology and Community Health Sciences University of Calgary | Canada  MedicalResearch.com: What is the background for this study? Response: Urinary incontinence disproportionately affects women. Urinary incontinence results in significant physical, social, and psychological adverse consequences that impair women’s quality of life and contribute to considerable healthcare costs. At the moment, the contemporary prevalence and recent trends in urinary incontinence in US women are unknown. More importantly, there is a growing awareness that urinary incontinence is not part of normal aging, but very little information is available to inform prevention strategies. Therefore, we were also interested in exploring correlates of urinary incontinence in a population-based sample of US women. (more…)
Author Interviews, Brigham & Women's - Harvard, Cancer Research, COVID -19 Coronavirus, Prostate, Prostate Cancer, Surgical Research, Urology / 01.02.2021

MedicalResearch.com Interview with: David-Dan Nguyen Research Fellow | Center for Surgery and Public Health, Brigham and Women's Hospital MPH (Health Policy) Student | Harvard T.H. Chan School of Public Health Medical Student | McGill University MedicalResearch.com: What is the background for this study? Response: The COVID-19 pandemic has forced hospitals to delay the definitive treatment of cancers via surgery or radiation therapy. While previous evidence has shown that delaying the treatment of low-risk prostate cancer is not associated with worse outcomes, treatment delays for intermediate-risk and high-risk prostate cancer are more controversial. As such, we sought to determine if delays for these disease states negatively impacted oncological outcomes. (more…)

MedicalResearch.com Interview with: Kari Tikkinen, MD, PhD, Adjunct Professor Departments of Urology and Public Health University of Helsinki and Helsinki University Hospital Helsinki, Finland MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Men’s choice of whether to undergo screening is value and preference sensitive: fully informed men will make different choices depending on their experience and perspective. For such decisions, shared decision-making represents an ideal approach to decision making. In shared decision-making both the patient and health care provider contribute to the medical decision-making process. The health care provider explains alternatives to patients, informs them of the best evidence regarding the anticipated consequences of a decision for or against the intervention, and helps them choose the option that best aligns with their preferences. All major guidelines of prostate cancer screening acknowledge the importance of informing men about risks and benefits of PSA screening. Shared decision-making is challenging because it requires time, knowledge, and specific skills. Prostate cancer screening decisions aids may, by summarizing the current best evidence and by supporting conversations that address what matters most to men, address these challenges. The impact of decision aids on the decision-making process is, however, uncertain. We therefore undertook a systematic review and meta-analysis of the randomized trials that have addressed the impact of decision aids in the context of prostate cancer screening.  (more…)

MedicalResearch.com Interview with: Steven A. Kaplan, M.D., FACS Professor of Urology Director, The Men's Health Program Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Response: PLUS is the first large-scale trial conducted in North America and Europe specifically designed to study the effects of mirabegron in controlling residual symptoms of urinary urgency and frequency in men with benign prostatic hyperplasia (BPH) using common agents such as tamsulosin (Flomax). We explored whether mirabegron (Myrbetriq), an agent approved for the treatment of overactive bladder (OAB), improved patient outcomes when added to tamsulosin. This was a randomized, double-blind, placebo-controlled, multi-center study enrolling 715 male patients 40 years of age and older. (more…)
Author Interviews, Cancer Research, HPV, Urology / 13.05.2019

MedicalResearch.com Interview with: Lael S. Reinstatler, MD, MPH. PGY 4 Urology Residency Dartmouth Hitchcock MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Human Papillomavirus is an oncogenic virus associated with other genitourinary cancers including penile cancer. HPV is detectable in urine and in urethral swabs and it interacts with stratified squamous epithelium which lines the majority of the genitourinary tract. Prior research has identified HPV in bladder tumors but detection methods are inconsistent. In this study, we looked for an association with HPV serology (indicating prior HPV systemic exposure) and bladder cancer. (more…)

MedicalResearch.com Interview with: Stephen B. Williams, MD, FACS Chief, Division of Urology Associate Professor, Urology and Radiology Robert Earl Cone Professorship Director of Urologic Oncology Director of Urologic Research Co-Director Department of Surgery Clinical Outcomes Research Program University of Texas Medical Branch at Galveston MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite prior studies evaluating cancer in those living near and working in oil refineries, there remains a gap in knowledge regarding proximity to oil refineries and risk of bladder cancer. Aromatic amines have been associated with increased risk of various cancers including bladder cancer. Texas is a home to the largest numbers of oil refineries in the US. Our goal was to evaluate if there was a link between bladder cancer and living in close proximity to an oil refinery in Texas. Our data did suggest that living within 10 miles of an oil refinery was associated with a small increase in risk of bladder cancer. These data support further research to validate these findings.

Author Interviews, BMJ, Diabetes, Prostate, Urology / 24.04.2019

MedicalResearch.com Interview with: Professor Ruth Andrew PhD Chair of Pharmaceutical Endocrinology University/BHF Centre for Cardiovascular Science Queen's Medical Research Institute University of Edinburgh  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our research group has been interested for a number of years in how stress hormones (called glucocorticoids) influence the risk of heart disease and diabetes. Glucocorticoids help us control stress and regulate how the body handles its fuel, for example the carbohydrate and fat we eat. However exposure to high levels of glucocorticoids, can increase the risk of diabetes, obesity and high blood pressure. We studied men with prostate disease who took 5α-reductase inhibitors, because over and above the beneficial actions of these drugs in the prostate, they also slow down inactivation of glucocorticoids. We had carried out some short term studies with the drugs in humans and found that they reduced the ability of insulin to regulate blood glucose. Therefore in the study we have just published in the BMJ, we examined how patients receiving these drugs long-term responded and particularly we were able to show that over an 11 year period that there was a small additional risk of developing type 2 diabetes, the type of disease common in older people, compared with other types of treatments.

Author Interviews, Depression, JAMA, Surgical Research, Urology / 14.01.2019

MedicalResearch.com Interview with: Blayne Welk MD, MSc, FRCSC Associate Professor of Surgery St. Joseph's Hospital Western University MedicalResearch.com: What is the background for this study? What are the main findings? Response: I found that when I was referred women with midurethral sling complications, they were often quite emotional and described a significant period of time when they struggled with the complications before they were referred to someone to assess them. The study looked at the rate of depression and self-harm behavior of women who had surgery for midurethral sling complications compared to women who did not have midurethral sling complications. I found that there was an increased risk of both of these outcomes among women who had surgery for complications, however this risk was primarily present in younger women. (more…)

MedicalResearch.com Interview with: "Glass of Water" by Iwan Gabovitch is licensed under CC BY 2.0Professor Yair Lotan MD Chief of Urologic Oncology Holder of the Helen J. and Robert S. Strauss Professorship in Urology UT Southwestern Medical Center at Dallas Department of Urology Dallas, Texas 75390-9110  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Urinary tract infections are extremely common in women and many women experience recurrent episodes which impact their quality of life.  There are also many women who do not drink as much water as is recommended. This study found that in healthy women with recurrent UTIs who drink less than 1.5 liters per day, the additional intake of 1.5 liters of water daily reduced the risk of recurrent infections by nearly 50%.  (more…)

MedicalResearch.com Interview with: Prof. Hashim Ahmed Professor and Chair of Urology Imperial College London MedicalResearch.com: What is the background for this study? What are the main findings? Response: Men with localised clinically significant prostate cancer currently undergo radical (whole gland) surgery or radiotherapy. These treatments are effective but can cause urine leakage in 5-30% and erectile dysfunction in 30-60%. Radiotherapy can cause rectal problems in 5%. So, although there is benefit in treating the cancer in these men, the side effects significantly affect the quality of life.  (more…)

MedicalResearch.com Interview with: Dr. Fred Saad, MD FRCS Professor and Chief of Urology Director of GU Oncology Raymond Garneau Chair in Prostate Cancer University of Montreal Hospital Center (CHUM) Director, Prostate Cancer Research , Montreal Cancer Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: Patient Reported Outcomes (PRO) data from the Phase 3 SPARTAN study showed adding ERLEADA (apalutamide) to androgen deprivation therapy (ADT) for patients with nmCRPC who were asymptomatic and well, did not worsen or cause detriment to HRQoL when compared to the placebo.The percent of patients who felt “quite a bit” or “very much” bothered was low (<2–6 percent of patients in the apalutamide group and 0–6 percent of those in the placebo group), suggesting that ERLEADA treatment was generally well-tolerated. This outcome, coupled with the efficacy results seen in SPARTAN, suggest that apalutamide can be given to patients at risk of metastasis without worry about compounded side effects or negative HRQoL..

MedicalResearch.com Interview with: Dr. Fred Saad, MD FRCS Full Professor and Chief of Urologic Oncology, CHUM; Medical Director of Interdisciplinary Urologic Oncology Group, CHUM; Department of Surgery/Faculty of Medicine; Institut du cancer de Montréal/CRCHUM MedicalResearch.com: What is the background for this study? What are the main findings? Response: The SPARTAN study was a Phase 3, randomized, double-blind, placebo-controlled, multicenter study that evaluated ERLEADA (apalutamide), a next-generation androgen signaling inhibitor, in patients with non-metastatic castration-resistant prostate cancer (nmCRPC) who had a rapidly rising PSA (PSA doubling time ≤10 months). The post-hoc analysis presented at the American Urological Association (AUA) 2018 annual meeting showed in patients who received the treatment apalutamide while receiving continuous androgen deprivation therapy (ADT) significantly decreased the risk of PSA progression by 94 percent compared with the placebo group.

MedicalResearch.com Interview with: Kristen L. Knutson, PhD Associate Professor Center for Circadian and Sleep Medicine Department of Neurology Northwestern University Feinberg School of Medicine Chicago, IL  60611​Premal Patel, MD, PGY-5 Urology University of Manitoba MedicalResearch.com: What is the background for this study? What are the main findings? What should readers take away from your report? Response: Within the literature there has only been small experimental studies which looked at impaired sleep and testosterone. To our knowledge, there has been no study that has evaluated sleep and testosterone using a population dataset. We utilized the National Health and Nutrition Examination Survey to assess the association of sleep with serum testosterone. NHANES examines a nationally representative sample of about ~5000 persons each year. After performing a multivariate linear regression of numerous variables within the NHANES database (age, marital status, prior co-morbidities, number of hours of sleep, etc…) we found that a reduction in the number of hours slept, increasing body mass index and increasing age were associated with lower testosterone levels. Given that this is a cross-sectional analysis, we are unable to provide causality of this relationship but we do feel it is important to counsel patients with low testosterone about the importance of living a healthy lifestyle which includes a well-balanced diet, exercise and sufficient sleep.

MedicalResearch.com Interview with: Gregory Tasian MD, MSc, MSCE Assistant Professor of Urology and Epidemiology University of Pennsylvania Perelman School of Medicine Division of Urology and Center for Pediatric Clinical Effectiveness The Children’s Hospital of Philadelphia MedicalResearch.com: What is the background for this study? What are the main findings? Response:  We found that five classes of commonly prescribed antibiotics were associated with an increased risk of kidney stones. These classes were sulfa drugs (e.g. Bactrim), fluoroquinolones (e.g. Cipro), cephalosporins (e.g. cephalexin), nitrofurantoin, and broad-spectrum penicillins (e.g. augmentin).  For those five classes of antibiotics, the greatest risk was found among younger patients. However, the increased risk was still significant across all ages, including for older adults with the exception of broad-spectrum penicillins, which were not associated with an increased risk of kidney stones among patients >75 years of age. We conducted this study because: 1) Prior investigations have demonstrated that changes in the gut microbiome were associated with kidney stones, 2) Antibiotics are prescribed frequently, and 3) The number of people affected by kidney stone disease has increased 70% over the last 30 years and the greatest increases have been found among children and adolescents. Our results were consistent with these previous studies, so we were not surprised with the findings although we did not know which specific classes of antibiotics would be associated with an increased risk of stones and which ones would not.

MedicalResearch.com Interview with: https://www.churchillpharma.com/ Paul Nemeth, Ph.D. Sr. Vice President, Regulatory Affairs, Clinical Development & Quality Assurance Churchill Pharmaceuticals LLC King of Prussia, PA 19406 MedicalResearch.com: What is the background for this study? Response: In the STAAR study, 53 patients with metastatic castration-resistant prostate cancer (mCRPC) were randomized to receive YONSA, an abiraterone acetate fine particle formulation 500 mg once daily in combination with 4 mg of methylpresnisolone twice daily or 1,000 mg daily of the originator abiraterone acetate (OAA) in combination with 5 mg of prednisone twice daily for a period of 84 days.  Previous studies in healthy volunteers under fasted conditions had shown that single oral doses of 500 mg of YONSA are bioequivalent to single oral doses of 1,000 mg OAA and that a background of 4 mg of methylprednisolone twice daily on a single oral dose of 500 mg of YONSA results in the same extent of absorption as a background of 5 mg of prednisone twice daily on a single oral dose of 1,000 mg of OAA.  (more…)

MedicalResearch.com Interview with: Robert Nam, MD, FRCSC Ajmera Family Chair in Urologic Oncology Professor of Surgery University of Toronto Head, Genitourinary Cancer Site Odette Cancer Centre Sunnybrook Health Sciences Centre  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The well known potentially lethal complications of anti-thrombotic medications of cerebral and gastrointestinal bleeding complications are well known.  However, more common bleeding related complications are not well described .  In particular, gross hematuria is a well known complication of these medications but its frequency and severity is unknown.  We sought to characterize this association among a large population-based cohort consisting of over 2.5 million patients from the Province of Ontario, Canada, using hematuria-related complications was endpoints.  These were defined as undergoing invasive urologic procedures, hospital admissions or emergency visits for gross hematuria.

MedicalResearch.com Interview with:
Thomas W. Gaither, BS Department of Urology University of California, San Francisco General Hospital, San Francisco
MedicalResearch.com: What is the background for this study? What are the main findings? Response: We study genitourinary trauma and reconstruction. This study was motivated from a previous study showing that Emergency Room visits due to grooming were increasing over the past nine year. We sought to better characterize who was at most risk for grooming injuries. We found that grooming is extremely common in both men and women and minor injuries occur in about 25% of groomers. Surprisingly, a little over one percent sought medical care due to their injury. Participants at most risk our those who remove all of their pubic hair frequently ( as opposed to those who just trim). We did not find any instruments that were necessarily putting participants at risk for injury. (more…)

MedicalResearch.com Interview with: Baoyan Liu, MD Guang’an Men Hospital China Academy of Chinese Medical Sciences Beijing, China MedicalResearch.com: What is the background for this study? What are the main findings? Response: The prevalence of stress urinary incontinence(SUI) is as high as 49% and varies according to the population studied and the definition of stress urinary incontinence. SUI causes psychological burden, affects relationships, lowers physical productivity, and decreases quality of life in women. Yet, few effective therapies are available for treating stress urinary incontinence. In this randomized clinical trial that included 504 women, the mean decrease in urine leakage, measured by the 1-hour pad test from baseline to week 6, was 9.9 g with electroacupuncture vs 2.6 g with sham electroacupuncture, a significant difference.

MedicalResearch.com Interview with: Vikas Gulani, MD, PhD Director, MRI, UH Cleveland Medical Center Associate Professor, Radiology, CWRU School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: We wanted to learn if performing MR before prostate biopsy, followed by MR guided strategies for biopsy, are cost effective for the diagnosis of prostate cancer in men who have not previously undergone a biopsy and who have a suspicion of prostate cancer. The most significant findings are as follows: We found that all three MR guided strategies for lesion targeting (cognitive targeting, MR-ultrasound fusion targeting, and in-gantry targeting) are cost effective, as the increase in net health benefits as measured by addition of quality adjusted life years (QALY), outweigh the additional costs according to commonly accepted willingness to pay thresholds in the United States. Cognitive targeting was the most cost effective. In-gantry biopsy added the most health benefit, and this additional benefit was cost-effective as well. (more…)

MedicalResearch.com Interview with: Dr. Nikhil K. Gupta and Kevin McVary, MD, FACS Professor, Department of Surgery Chair, Division of Urology Southern Illinois University School of Medicine MedicalResearch.com: What is the background for this study? Response: Male lower urinary tract symptoms due to benign prostatic hyperplasia, or LUTS due to BPH, have most commonly been treated with a combination of medication, such as alpha-blockers and 5-alpha reductase inhibitors, and surgery, such as transurethral resection of prostate (TURP) and Greenlight photovaporization of prostate (PVP). These treatments, however, have potentially serious adverse and sexual side effects. Minimally invasive surgical therapies (MIST) for LUTS due to BPH have tried to thread the needle between medications and invasive surgery, giving effective relief of symptoms with minimal anesthetic need while preserving sexual function. Previously developed MISTs have been unable to provide durable relief of symptoms, causing patients to undergo multiple treatments in a short period of time, and have been limited by prostate size and conformation, e.g. the inability to treat a middle lobe or median bar. LUTS due to BPH is also very strongly and likely causally linked with obesity, and obesity seems to have an effect on the efficacy of treatment as well, as obesity affects response to medication and tends to dampen the treatment effect of TURP. Convective Radiofrequency Water Vapor Energy ablation of the prostate, named Rezūm®, is a new MIST that uses radiofrequency to generate energy in the form of water vapor. The water vapor acts as a convective energy source and, once injected into the treatment area, distributes itself evenly within the treated tissue, causing uniform necrosis througout the treated area. This mechanism using convection is in contrast to previous technologies using conductive heat energy, which created a heat gradient with tissue closest to the heat source receiving the largest amount of energy and tissue farthest from the heat source receiving almost no energy. Thus conductive energy has a different effect on different parts of the treated area. With Rezūm, MRI studies have shown that the water vapor creates a uniform treatment effect while staying within collagen barriers, obeying natural tissue planes and affecting only the intended treatment areas. The purpose of this study was to determine the efficacy of Rezūm in treatment of LUTS due to BPH, examine the treatment's effect on sexual function, and to determine whether obesity affected treatment efficacy.

MedicalResearch.com Interview with: Dr. Michael Krychman, MD Executive Director: The Southern California Center for Sexual Health and Survivorship, Medical Director: Sexual Medicine at Hoag Hospital Newport Beach CA Clinical faculty member University of Southern California Los Angeles, CA MedicalResearch.com: What is the background for this study? What are the main findings? Response: This post hoc analysis pooled data from three 24-week, double-blind, placebo-controlled studies (VIOLET, DAISY, and BEGONIA) of flibanserin in premenopausal women with acquired, generalized HSDD5-7. Patients who received flibanserin 100 mg once daily at bedtime (qhs) or placebo were included in the analysis. The Female Sexual Function Index (FSFI) consists of 19 items across 6 domains. Scores range from 2 to 36. Higher scores indicate better sexual functioning. Scores under 26 indicate sexual dysfunction. Analysis of covariance was used to evaluate changes from the first week to week 24 in the FSFI domain and total scores were compared for flibanserin 100 mg qhs versus placebo. For patients who discontinued study participation prior to week 24, the last postbaseline observation was carried forward (LOCF). Results found that treatment with flibanserin 100 mg qhs produced statistically significant improvement, relative to placebo, on all domains of the FSFI (desire, arousal, lubrication, orgasm, satisfaction and pain) in premenopausal women with acquired, generalized hypoactive sexual desire disorder (HSDD).

MedicalResearch.com Interview with: Keyan Salari, MD, PhD Resident in Urologic Surgery Keyan Salari is currently completing his residency in the Harvard Program in Urologic Surgery at the Massachusetts General Hospital, and is conducting post-doctoral research in cancer genomics in the Garraway Lab at the Dana-Farber Cancer Institute and the Broad Institute of Harvard and MIT MedicalResearch.com: What is the background for this study? Response: Active surveillance is an effective strategy addressing the problem of over treatment of clinically indolent prostate cancer, but data on the role of active surveillance in younger men is limited. Younger men diagnosed with prostate cancer are typically counseled to undergo treatment as opposed to surveillance of their prostate cancer. To potentially expand the role of active surveillance to younger patient populations, we undertook this study evaluating the outcomes of younger men under 60 years of age who elected to pursue active surveillance of their prostate cancer.

MedicalResearch.com Interview with: Eric A. Klein, MD Chairman, Glickman Urological and Kidney Institute Cleveland Clinic MedicalResearch.com: Which of these results did you find most interesting or surprising? Response: What’s most interesting is that the IsoPSA assay redefines how PSA is measured, which links it more closely to the underlying biology of cancer. Current assays measure only the concentration of PSA, which can be affected by conditions other than cancer – BPH most commonly, but also infection and inflammation – which limits its diagnostic accuracy for finding cancer. Its been known for several decades that PSA exists in multiple different forms in the bloodstream in patients with prostate cancer. These novel molecules arise because cancer cells have deranged cellular metabolism that result in the generation of new species of PSA, making their measurement more tightly linked to the presence or absence of cancer and even the presence of high grade cancer (where cellular metabolism is even more disordered). The IsoPSA assay is the first assay to measure all of these isoforms and thus has better diagnostic accuracy for cancer. (more…)
