Transurethral resection of the hyperplastic prostate and bladder tumor using bipolar plasmakinetic technique

Objective To assess the efficacy and safety of transurethral resection of the prostate(PKRP) and bladder tumor(PKRBT) with plasmakinetic energy. Methods 300 patients(mean age of 71.6 years;range from 52 to 91) with symptomatic BPH without suspected cancer (confirmed by IPSS,urinary flow rate,ultrasonographic estimate and PSA tests) were treated by PKRP. 37 patients with superficial transitional cell carcinoma (17 with tumors appearing at the lateral wall) were treated by PKRBT.All patients were followed up for 1～6 months postoperatively. Results For PKRP,the duration of the procedure was (48±31) min(range 13 to 98 min).No case need blood transfusion during the operation.No transurethral resection syndrom occurred.The mean catheterization time was 2 days (1 to 4 days). The peak flow rate increased from (5.2±3.9) to (19.2±4.1),(21.8±4.6),(22.3±5.7)ml/s at 1,3 and 6 months respectively. The IPSS decreased from 24.7 to 5.7, 5.4,5.0 and the QOL decreased from 5.3 to 1.7,1.8,1.2 at 1,3 and 6 months respectively.For PKRBT,the duration of the procedure was (24±13) min(range 5 to 39 min) with little bleeding.The adductor reflex was found in 5 of the 17 cases with tumor located at the lateral wall. Conclusions It is suggested that transurethral bipolar plasmakinetic resection of the prostate and bladder tumor is effective and safe. This pilot series permits a comparative study with conventional TUR system.
