Improvement of lower urinary tract symptoms and sexual activity after open simple prostatectomy: prospective analysis of 50 cases

Abstract

OBJECTIVES: To evaluate the improvement of Lower Urinary Tract Symptoms (LUTS) and Erectile Function (EF) evaluated before and after Open Simple Prostatectomy, focusing on which patients this procedure allows better outcomes in term of sexual activity. MATERIAL AND METHODS: 50 men with large size benign prostatic hyperplasia (BHP) greater than 80 gr were prospectively evaluated before and 6 months after Open Simple Prostatectomy (Freyer procedure) between October 2012 to September 2013. Patients had a pre-operative transrectal ultrasound (TRUS) for volume evaluation and filled pre and post operative questionnaires for International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF-5) score. RESULTS: Mean patients age was 71 years (D.S. 3,5), mean prostate volume results 103 ml (D.S. 23,7); regarding LUTS and EF, mean improvement of IPSS score was 15,3 (D.S. 4) and mean increase of IIEF-5 score was 3,4 (D.S.3). This study highlights a correlation between patients' age and increase of IIEF-5 score; no correlation with prostate size was found. CONCLUSION: According to the EAU Guidelines 2014, large size BPH (over 80-100 mL) with LUTS refractory to medical management continue to have open prostatectomy as the treatment of choice. In our experience we found not only an reduction of LUTS after the procedure but also an improvement of erectile function; this improvement was related with patient's age.
