Comparison of Bipolar Electrocautery Device and Traditional Monopolar Electrocautery Device in TURP for the Treatment of Benign Prostatic Hyperplasia-Preliminary Report

比較雙極電刀及單極電刀在治療良性攝護腺增生的內視鏡刮除手術其效能與安全性-初步報告

摘要


The major complication of traditional monopolar TURP is water intoxication due to distilled water absorption during resection. The new bipolar electrocautery device can be used in TURF procedure using saline irrigation and therefore decrease TUR syndrome. The aim of this study is to evaluate the efficacy and the safety of this new system in TURF. From April to October 2003, totally 40 patients aged 58 to 86 years (means: 69.3) were randomly assigned to receive bipolar or monopolar TURF. Pre-operative and post-operative serum sodium concentration, hemoglobin level, resection time, blood loss and weight of specimen were checked. Qmax, I-PSS, IIEF-5 and bladder neck contracture were reassessed at the 6-month and I-year visits. Results: There were no significant differences in hemoglobin level, blood loss, resection time and weight of specimen between two groups. The difference of serum sodium level change after the operation was significant between these 2 groups (P<0.001). Bipolar electrocautery device is safer than traditional mono electrocautery device fur TURP procedure by decreasing of TUR syndrome and produces the similar results at 6 months and 1 year of follow-up.
