چکیده
BACKGROUND AND PURPOSE Radical prostatectomy is commonly performed for the treatment of patients with prostate cancer. Several studies have demonstrated a reduction in penile size after open radical retropubic prostatectomy. The objective of this study is to describe changes in penile length after after robot-assisted laparoscopic radical prostatectomy (RALRP). PATIENTS AND METHODS We performed a randomized, open label, multicenter study in men with normal erectile function who underwent bilateral nerve-sparing radical prostatectomy. We evaluated changes in measured stretched penile length (SPL), a secondary end point of the study, in a subset of men from a single site who underwent RALRP by one surgeon. They were randomized to either intraurethral alprostadil 125 to 250 μg daily or oral sildenafil citrate 50 mg daily for 9 months. SPL was measured from pubic bone to coronal sulcus using a semirigid ruler before surgery and at 1, 3, 6, 9, 10, and 11 months. RESULTS A total of 127 patients were enrolled and 94 completed the 11-month follow-up. The mean patient age was 56.5 years. Baseline mean SPL (cm) before surgery was 11.77 and decreased to 11.13 at 1 month (P<0.0001). A trend toward recovery of SPL was seen at 3 and 6 months. Mean SPL was not significantly different from baseline at 9, 10, and 11 months. CONCLUSIONS This report describes changes in SPL over time after RALRP for prostate cancer. The expected decrease in length was observed shortly after surgery, but, by 9 months, penile length had returned to the preoperative measurement.

Robot-Assisted Radical Prostatectomy in a Patient with a Preexisting Three-Piece Inflatable Penile Prosthesis
We report a rare case of robot-assisted laparoscopic radical prostatectomy (RARP) in a patient with a preexisting penile prosthesis. In this case, we completed RARP without removing the reservoir by using a deflation-inflation technique, and there were no complications related to the prosthesis. The patient had a negative surgical margin. The preserved three-piece inflatable penile prosthesis c...

PURPOSE Despite the large number of analytical reports regarding the learning curve in the transition from open to robot-assisted radical prostatectomy (RARP), few comparative results with laparoscopic radical prostatectomy (LRP) have been reported. Thus, we evaluated operative and postoperative outcomes in RARP versus 100 simultaneously performed LRPs. MATERIALS AND METHODS A single surgeon ...

متن کاملCurrent status of laparoscopic and robot-assisted nerve-sparing radical cystectomy in male patients
During radical cystectomy (RC), the neurovascular bundles are easily removed or damaged, leading to varying rates of incontinence and erectile dysfunction. The nerve-sparing technique was developed to preserve urinary and erectile function. The adoption of laparoscopic and robot-assisted technology has improved visualization and dexterity of pelvic surgeries, thus facilitate the nerve-sparing t...
