Objective: Bipolar transurethral resection of the prostate (TURP) is a minimally invasive procedure that causes fewer problems, and a faster resection, but requires more expensive equipment. It is the treatment of choice for benign prostatic hyperplasia. In this study, its outcomes will be compared to those of conventional monopolar TURP.

Materials and Methods: Twenty-seven patients aged between 52 and 65 years underwent either monopolar TURP (Group 1, n: 15) or bipolar TURP (Group 2, n: 12). Preoperative and perioperative data were recorded and analyzed, including the maximal flow rate (Qmax), prostate volume, intraoperatively resected tissue volume, resection velocity, and operation time.

Results: Preoperative mean prostate volumes in Groups 1, and 2 were 82.6 ± 21 ml and 78.8 ± 12 ml, respectively (p=0.117). Preoperative mean serum sodium levels were 140.4 ± 2.3 mmol/l in Group 1 and 139.8 ± 2.2 mmol/l in Group 2. Preoperative mean serum hemoglobin values were 15 ± 0.8 g/dl in Group 1, and 14.5 ± 2.2 g/dl in Group 2. Postoperative mean serum sodium levels were 130.6 and 136.7 mmol/l, in Groups 1, and 2, respectively. Eight patients from the monopolar TURP group exhibited a notable drop in serum sodium levels. In the monopolar TURP group, there were 5 occurrences of TUR syndrome and 2 patients needed blood transfusions due to a mean decrease of 5 g/dl in hemoglobin levels. Complications were identified in 7 cases.

Conclusion: Compared to monopolar TURP, bipolar TURP is associated with a shorter hospital stay, and lower transfusion and complication rates.
