MedicalResearch.com: What is the background for this study? What are the main findings?
Response: I had experienced some patients who underwent radical prostatectomy (RP) complained penile shortening after RP. Once I checked that kind of reports, some reports mentioned the phenomenon of penile shortening (PS) after radical prostatectomy; however, the results were little bit different and the reasons of PS after RP were not well elucidated.
Therefore, we started our study to obtain our data. In our study, the penile length (PL) was measured before, 10 days after, and at 1, 3, 6, 9, 12, 18, and 24 months after RP. And the PL at 10 days after RP was shortest, and it gradually recovered thereafter. Penile length at 12 months after radical prostatectomy was not significantly different from preoperative penile length. Based on MRI investigation, slight vertical repositioning of the membranous urethra after radical prostatectomy caused chronological changes in penile length.
