Short-term functional outcomes and complications associated with transperineal template prostate mapping biopsy.

Journal Article (Journal Article)

OBJECTIVE: To assess the complications and erectile and urinary functional outcomes of transperineal template mapping biopsy (TTMB) of the prostate. METHODS: We retrospectively reviewed the records of 84 patients undergoing TTMB at our institution and recorded complications and functional outcomes. Erectile and urinary functions were measured at baseline, 2 weeks, and 6 ± 2 weeks after TTMB using the International Index of Erectile Function short version (IIEF-5) and International Prostate Symptom Score questionnaires. Erectile and urinary function parameters were compared between baseline and 2 and 6 weeks after TTMB in a paired fashion. A subanalysis of erectile function was performed in preoperatively potent men (IIEF-5 >17). RESULTS: Sixteen patients (19%) experienced complications. The most common events were transient urinary retention (6%), prostatitis (4%) and local events, including perineal hematoma, bruising, or perineal pain (5%). One patient with hematuria required intervention. IIEF-5 scores at baseline, 2 weeks, and 6 weeks were 20 (interquartile range [IQR], 16-23), 18 (IQR, 12-22), and 18 (IQR, 12-22), respectively (P = .096 and P = .034). Among preoperatively potent men, IIEF-5 scores at baseline, 2 weeks, and 6 weeks were 22 (IQR, 20-24), 21 (IQR, 18-24), and 22 (IQR, 18-24), respectively (P = .011 and P = .018). International Prostate Symptom Scores were 6 (IQR, 3.5-11) at baseline, rose to 10 (IQR, 4.8-15) at 2 weeks (P = .012), and returned to 7 (IQR, 3.5-13) at 6 weeks (P = .628). CONCLUSION: TTMB has a favorable morbidity profile, with mostly mild and transient complications. Urinary retention occurred in 6%, and only 1 patient required intervention with bladder irrigation. Despite a statistically significant decline in erectile function from baseline, the median change in IIEF-5 score was 1 point. Urinary symptoms worsened initially but returned to baseline within 6 weeks.
