Erectile dysfunction, transurethral prostatectomy


Background: Previous studies about erectile dysfunction after transurethral prostatectomy is contro- versial (rate of Erectile dysfunction 3-20%), and there was no report in Thai male.

Objective: To assess erectile dysfunction after transurethral prostatectomy, what is incidence?, risk factors that contribute to erectile dysfunction (ED).

Materials and method: 91 patients underwent TURP in our department for the treatment of sympto- matic BPH. All patients were evaluated for, International Prostate Symptom Score (IPSS) and quality of life (QOL) preoperatively. Finally, the erectile function of the patient was evaluated according to the Interna- tional Index of Erectile Function Instrument (IIEF-5) questionnaire. It was determined that ED existed where there was a total score of less than 21. The IPSS and QOL assessment were performed at 3 months post- treatment. A logistic regression analysis was used to identify potential risk factors for ED.

Result: The mean patient age was 70 years. The ED rate was 59 %. 3 months after TURP, the rate of patients reporting ED increased to 66 %. Statistical analysis revealed that the only important factors associated with newly reported ED after TURP were diabetes mellitus (Odd ratio 15.3, P 0.045) and observed intraoperative capsular perforation (Odd ratio 45.6, P 0.004).

Conclusion: The incidence of postoperative, newly reported ED after TURP was 7%. Risk factors for its occurrence were diabetes mellitus and intraoperative capsular perforation
