OBJECTIVE Bleeding is one of the most common complications of transurethral resection of the prostate (TURP). Several previous studies reported that administering dutasteride before surgery could reduce perioperative bleeding. We aimed to evaluate the efficacy of preoperative dutasteride treatment in benign prostatic hyperplasia patients undergoing TURP by performing a meta-analysis of relevant randomized controlled trials (RCTs). METHODS A comprehensive literature search was performed through the electronic databases including Medline, Cochrane Library, Google Scholar, and in October 2020. RCTs evaluating the role of dutasteride for TURP were screened using the eligibility criteria and the quality of RCTs was assessed using the Cochrane Risk of Bias Tool. The heterogeneity was assessed using I (2) statistic. The measured outcomes were hemoglobin (Hb) levels, perioperative blood loss, blood transfusion, microvessel density (MVD), and operation time. Data were pooled as mean difference (MD) and odds ratio (OR). RESULTS A total of 11 RCTs consisting of 627 samples from the treatment group and 615 samples from the placebo group were analyzed. Patients that received dutasteride had less reduction in Hb levels (MD -1.10, 95% confidence interval [CI] -1.39 to -0.81, p<0.00001). Dutasteride also significantly reduced the operation time (MD -1.79, 95% CI -2.97 to -0.61, p=0.003) and transfusion rate after surgery (OR 0.34, 95% CI 0.15 to 0.77, p=0.009) compared to the control group. However, the MVD (MD -3.60, 95% CI -8.04 to 0.84, p=0.11) and perioperative blood loss in dutasteride administration for less than 4 weeks (MD 46.90, 95% CI -144.60 to 238.41, p=0.63) and more than 4 weeks (MD -190.13, 95% CI -378.05 to -2.21, p=0.05) differences were insignificant. CONCLUSION Preoperative administration of dutasteride is able to reduce bleeding during TURP, as indicated by less reduction in Hb level, lower transfusion rate, and less operation time.
