Erectile function after repeat saturation prostate biopsy: Our experience in 100 patients

Introduction: Erectile dysfunction (ED) incidence following repeat saturation prostate biopsy (SPBx) was evaluated. Materials and methods: From January 2011 to June 2012 295 patients underwent repeat transperineal SPBx (median 28 cores) under sedation. The indications for biopsy were: abnormal DRE, PSA > 10 ng/mL or included between 4.1-10 with free/total PSA < 25%. All patients were prospectively evaluated with the 5-item version of the International Index of Erectile Function (IIEF-5) at baseline and 1, 3 and 6 months from SPBx. Results: 100/200 men with benign histology and normal sexual activity completed the study; median IIEF-5 score before and after SPBx was equal to 18.3 (baseline) vs 17.8 (1 month later) vs 18 (3 months later) vs 18.1 (6 months later) (p > 0.05); in detail, 1 month from biopsy 5 (5%) men referred a mild ED that disappeared at 3 and 6 months evaluation. Conclusions: Repeat transperineal SPBx under sedation did not significantly worsened erectile function; the minimal risk of temporary post-biopsy ED could be previously discussed (not emphasised) with potent patients.
