Outcomes of bipolar TURP compared to monopolar TURP: A comprehensive literature review.

Objective: Transurethral resection of the prostate (TURP) is the commonest surgical procedure for the treatment of benign prostatic obstruction (BPO). Bipolar-TURP (BTURP) is being increasingly used as compared to the long-established Monopolar TURP (MTURP). In this systematic review, we compared the outcomes of BTURP vs MTURP. Material and methods: A systematic review was conducted using PubMed, EMBASE, Scopus, Google Scholar, and the Cochrane library using relevant search terms from inception of databases till June 2020. Using PRISMA methodology, 18 randomized control trials were reviewed comparing MTURP vs BTURP with a total of 8,393 patients. Results: A significant drop in serum sodium was seen in four studies in MTURP vs BTURP and while there was zero incidence of TUR syndrome in BTURP group, there were 1-16 episodes of TUR syndrome across studies in the MTURP group. A significant fall in hematocrit was seen in three of nine studies with MTURP and one with a significant difference in blood transfusion rates. There were no significant differences in the incidence of clot retention across the studies with 1-5 cases in BTURP group vs 2-12 cases in MTURP group. There were no significant differences related to the duration of catheterization, operative time, resection volume, length of stay, quality of life, postoperative urethral stricture, and sexual function. Conclusion: Although both BTURP and MTURP improve urinary symptoms, BTURP is associated with less risk of hyponatremia, TUR syndrome, and blood loss compared to MTURP. There seems to be no significant difference in length of stay, urethral stricture, quality of life, and operative duration. [ABSTRACT FROM AUTHOR]
