Transurethral resection of the prostate with microprocessor controlled electrosurgical unit

Purpose: We analyzed the efficacy and side effects of a microprocessor controlled high frequency unit for transurethral resection of the prostate. Materials and Methods: A high frequency device with microprocessor control was used in 934 consecutive patients undergoing transurethral resection of the prostate. Indications for transurethral resection, medical history, preoperative findings, operative parameters, operative and immediate postoperative complications, and postoperative peak flow rate and residual urine were evaluated. Results: Postoperative peak flow rate and residual urine were comparable to those with standard transurethral resection of the prostate. One patient died on postoperative day 1 for a mortality rate of 0.1%. The immediate morbidity rate was 6.9%. Conclusions: Morbidity and mortality in this study were lower than those in previous series on transurethral resection of the prostate.
