ABSTRACT
OBJECTIVE: To investigate the efficacy of catheterization before transperineal ultrasound-guided prostate biopsy in reducing risk of urethrorrhagia. Currently, transperineal ultrasound-guided prostate biopsy (TPPB) is one of the most commonly used measures to help diagnose prostate cancer. However, whether the retention of catheterization before transperineal ultrasound-guided prostate biopsy is associated with the reduced risk of urethrorrhagia remains uncertain. METHODS: A cohort study was conducted in our hospital from January 2021 to September 2021. This study included 93 patients who participated in transperineal ultrasound-guided prostate biopsy. We compared the risk of urethrorrhagia in patients who underwent indwelling catheterization before biopsy and those who did that after biopsy, and performed an unadjusted analysis. We also analyzed the use of related confounding factors to limit the cohort of men, and applied propensity-score adjustment to control potential confounders. Analyses that restricted the cohort men with the related confounding factors and that used propensity-score adjustment to control for potential confounders. RESULTS: A total of 93 men were recruited in the cohort study, and the numbers of patients in group 1 and group 2 were 64 and 29, respectively. There were 34 patients (53.1%) of urethrorrhagia in group 1, and 22 patients (75.8%) of urethrorrhagia in group 2. This was a significant difference between the 2 groups (Pâ¯=â¯.008). After adjusting for correlative factors, the preoperative catheterization is still a protective factor for postoperative urethrorrhagia through multivariate multiple piecewise linear regression analysis. CONCLUSION: The result of this cohort study suggested that preoperative catheterization can significantly reduce the risk of urethrorrhagia.
