Long term erectile function results of radical perineal prostatectomy

Although many patients are being treated by radical prostatectomy (RP), there is still insufficient information about the changes in long-term erectile function after RP. Our aim is to examine long term, up to 5 year erectile function status of patients after Radical Perineal Prostatectomy (RPP).

One hundred and thirty-two patients, who underwent bilateral nerve-sparing Radical Perineal Prostatectomy (RPP) in between January 2012 and January 2017, with preoperative age≤70, prostate volume<80g, transrectal ultrasound (TRUS) guided biopsy Gleason score (GS)<7, prostate specific antigen (PSA) value<10ng/mL, and cT stage≤2 (N0, M0) were included into this study. Exclusion criteria were previous cardiovascular diseases, serious chronic renal and/or hepatic insufficiency, neurological diseases, uncontrolled diabetes mellitus, and severe lung diseases. Patients who received additional treatment (hormonal and/or radiotherapy) after RPP were also excluded from the study group. Erectile function was evaluated before surgery and at postoperative 3rd, 12th, and 60th months. Patients with an "International Index of Erectile Function (IIEF) - 5" score of ≥21 and patients whose IIEF-5 scores were between 16 and 20 but responded as "yes" to the "Sexual Encounter Profile (SEP) - 2" and "SEP-3" questions were accepted as having normal erectile function.

Out of the 132 patients, 96 (72.7%) of the patients were found to be potent in the first postoperative year. A total of 118 patients were evaluated at the end of 5 years. Eighty seven (73.7%) patients had normal erectile function according to our criteria.

According to the results of our study, short term and long term erectile function outcomes of patients undergoing RPP were favorable and there was no statistically significant difference between short and long term results.
