Introduction: There remains uncertainty regarding the differences in patient outcomes between monopolar transurethral resection of the prostate (MTURP) and bipolar TURP (BTURP) in the management of lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO).
Methods: A systematic literature search was carried out up to March 19, 2019. Methods in the Cochrane Handbook were followed. Certainty of evidence (CoE) was assessed using the GRADE approach.
Results: A total of 59 randomized controlled trials (RCTs) with 8924 participants were included. BTURP probably results in little to no difference in International Prostate Symptom Score (IPSS) at 12 months (MD -0.24, 95% confidence internal [CI] -0.39–-0.09; participants=2531; RCTs=16; moderate CoE) or health-related quality of life (HRQOL) at 12 months (MD -0.12, 95% CI -0.25–0.02; participants=2004, RCTs=11; moderate CoE), compared to MTURP. BTURP probably reduces TUR syndrome (relative risk [RR] 0.17, 95% CI 0.09–0.30; participants=6,745, RCTs=44; moderate CoE) and blood transfusions (RR 0.42, 95% CI 0.30–0.59; participants=5727, RCTs=38; moderate CoE), compared to MTURP. BTURP may carry similar risk of urinary incontinence at 12 months (RR 0.20, 95% CI 0.01–4.06; participants=751; RCTs=4; low CoE), re-TURP (RR 1.02, 95% CI 0.44–2.40; participants=652, RCTs=6, I2=0%; low CoE) and erectile dysfunction (International Index of Erectile Function [IIEF-5]) at 12 months (MD 0.88, 95% CI -0.56–2.32; RCTs=3; moderate CoE), compared to MTURP.
Conclusions: BTURP and MTURP probably improve urological symptoms to a similar degree. BTURP probably reduces TUR syndrome and blood transfusion slightly postoperatively. The moderate certainty of evidence available for primary outcomes suggests no need for further RCTs comparing BTURP and MTURP.
