Purpose: We investigated the predictive factors for acute urinary retention (AUR) after trans-perineal template-guided mapping biopsy (TTMB).
Materials and Methods: We retrospectively reviewed the records of 459 patients who had undergone TTMB between May 2017 and July 2020. Overall complications after TTMB were analyzed and categorized according to the Clavien-Dindo classification. Factors that were likely to affect AUR were analyzed using a logistic regression model.
Results: Overall complications after TTMB were observed in 95 of the 459 patients (20.7%), of which AUR was the most commonly reported (17.4%, n=80), followed by hematuria (3.1%, n=14). Hematuria in one patient was categorized as Clavien-Dindo grade IIIa. All remaining complications were Clavien-Dindo grade I. In the multivariate regression model, age ≥65 (odds ratio, 2.44; 95% confidence interval [CI], 1.42?4.17; p=0.001), prostate volume ≥30 mL (odds ra-tio, 3.72; 95% CI, 1.19?11.62; p<0.02), and number of biopsy cores ≥30 (odds ratio, 2.89; 95% CI, 1.29?6.43; p=0.01) were identified as the predictors for AUR after TTMB.
Conclusions: AUR is the most common complication after TTMB. Age ≥65 years, prostate volume ≥30 mL, and number of biopsy cores ≥30 were significant predictors of AUR following TTMB.
