OBJECTIVES: To investigate the effect of phosphodiesterase type 5 inhibitor on urinary continence recovery after bilateral nerve-sparing radical prostatectomy. METHODS: We analyzed data of 393 open bilateral nerve-sparing radical prostatectomies carried out between 2005 and 2010. Patients who recovered urinary continence within the first month after catheter removal (n = 52) were excluded. This resulted in 341 evaluable patients. Urinary continence recovery was defined as being completely pad free over a period of 24 h. Patients were stratified according to postoperative daily (n = 58; 17%), on-demand (n = 112; 32.8%) and no (n = 171; 50.1%) phosphodiesterase type 5 inhibitor use. The effect of phosphodiesterase type 5 inhibitor use on urinary continence was assessed using the Kaplan-Meier method. Uni- and multivariable Cox regression analyses were used to test the association between phosphodiesterase type 5 inhibitor and urinary continence recovery after adjusting for cofounders. RESULTS: At a mean follow up of 36.4 months after surgery (median: 33), 288 patients (84.5%) recovered urinary continence after bilateral nerve-sparing radical prostatectomy. Patients who did not use phosphodiesterase type 5 inhibitor after surgery had lower rates of urinary continence recovery at 1- and 2-year follow up as compared with patients taking phosphodiesterase type 5 inhibitor (67.1 vs 86.7% and 76 vs 94.4%, respectively; P < 0.001). After adjusting for all confounders, multivariable analysis showed that phosphodiesterase type 5 inhibitor use, either on demand or daily, had a positive impact on urinary continence recovery (P = 0.03). CONCLUSIONS: Patients taking phosphodiesterase type 5 inhibitor have higher urinary continence recovery rates as compared with patients left untreated after bilateral nerve-sparing radical prostatectomy. An improvement in sphincteric and pelvic floor blood supply might be responsible for this beneficial effect associated with the use of phosphodiesterase type 5 inhibitor.
