Bipolar versus monopolar transurethral resection of the prostate (TURP): A prospective study of two urology centers

Abstract

Background and objectives:Recently, using of bipolar transurethral resection of the prostate has challenged the for- mal monopolar transurethral resection of the prostate. The aim of this study was to evaluate the efficacy and safety of bipolar transurethral resection of prostate versus monopolar transurethral resection of prostate in the treatment of prostate enlargement. Methods: From September 2018 to April 2019, appropriate sample of 44 patients with symp- tomatic benign prostate hyperplasia randomly assigned to two groups, first group (n=21) operated on by monopolar transurethral resection of prostate, second group (n=23) operated on by bipolar transurethral resection of prostate in Rizgary Teaching Hospital and Zheen International Hospital, all patients were fully assessed preoperatively and postop- eratively by serum electrolyte, hemoglobin, operative time. Results: Mean resection time was 56.7 ± 5.8 minutes (mo- nopolar) and 63.1 ± 4.7 minutes (bipolar). The mean volume of irrigant was 17.6±1.6 liter (monopolar) and 20.4±1.8 liter (bipolar). The monopolar group showed a greater decrease in serum Sodium (5.7mEq/L) in contrast to the bipolar group (1.4 mEq/L), a statistically significant difference was detected. The monopolar group showed a statistically significant decrease in Hb (2.5 gm/dl) in contrast to the bipolar group (0.4 gm /dl). Conclusions: T he study showed that bipolar transurethral resection of prostate was superior to monopolar transurethral resection of the prostate with regards to less reduction in serum Sodium level and less decline in hemoglobin level as well as less hospital stay and catheterization days.
