Objective: To evaluate the efficacy and safety of using bipolar energy for transurethral resection (TUR) of superficial bladder tumors in No.103 Hospital. Subject and method: In total, 52 patients (45 males and 7 females) with superficial bladder carcinoma undergoing bipolar TUR of bladder tumors (B-TURBT) with the UES 40 Plasma kinetic Tissue Management System (Olympus) were studied. The patients were operated at a default setting of 150 W cutting and 80 W coagulation. Variables including tumor numbers, size, shape and location, operating time, length of hospital stay, blood loss in operation, as well as intraoperative and postoperative complications were all recorded. The resected tissues were examined and all of non-muscle infiltrant tumors were included in the study. Result: the average age of the patients was 59.8 +/- 12.51 years. Tumors were multiple in 36 (69.2 percent) and single in 16 (30.8 percent) patients with 42 (80.8 percent) on the lateral wall. The tumor size was 2.5 +/- 0.81cm with average resection time of 26.5 +/- 12 min. The mean drop in haemoglobin was 2.94 +/- 0.71 g/l (0.20-4.0), with a mean +/- SD (range) drop in haematocrit of 1.33 +/- 1.29 (1-3). None of the patients required blood infusion. Mean +/- SD drop in sodium was 0.06 +/- 0.66 mEq/L, with no patient developing TUR syndrome. Three of the 52 patients developed obturator jerks (5.8 percent) and one bladder perforation (1.9 percent). Conclusion: TURBT using bipolar energy was safe and effective in the treatment of superficial bladder tumors. However the complications of obturator jerks and bladder perforation were still recorded at low rates.
