Purpose Urinary retention occurs in 5%-36% of patients with prostate cancer after implantation of radioactive seeds for brachytherapy. We used transperineal biopsy as a model to determine the influence of needle trauma on urinary retention. Methods and material We retrospectively reviewed medical records of 157 men with high risk of prostate cancer who underwent systematic ultrasound-guided biopsy of the prostate with the transperineal template technique and an 18-gauge automated biopsy device. Results Eighteen of 157 patients (11.5%; 95% confidence interval, 6.9%-17.5%) had urinary retention within 48 hours after biopsy. Median age was 68.5 years in patients with retention vs. 67.0 years in patients without (p = 0.319); median calculated prostate volume, 76.5 vs. 51.5 mL (p = 0.015); and median number of biopsy cores, 22.0 vs. 20.0 (p = 0.038). Age distribution differed between groups (p = 0.047), with more younger men in the no-retention group. On multivariate analysis, only number of biopsy cores significantly predicted urinary retention (p = 0.003). Four patients required transurethral resection; 1 had an indwelling catheter until radical prostatectomy; and 13 were catheter-free within 1-5 days. Conclusions Needle trauma alone may cause urinary retention in men undergoing transperineal procedures. The number of needle incursions and prostate size are predictors of postprocedure urinary retention.
