title: Randomized comparison of loops for transurethral resection of the prostate: preliminary results.
abstract: OBJECTIVE
  To evaluate the comparative efficacy and morbidity of standard transurethral resection of prostate (TURP) and transurethral vaporesection (TUVRP) using four types of loops.
  
  
  METHODS
  In a one-to-one randomized study, 50 patients with lower urinary-tract symptoms suggestive of bladder outlet obstruction and benign prostatic enlargement underwent TURP. Clinical data were collected using digital rectal examination, transrectal ultrasonography for evaluation of prostate volume, IPSS and IIEF-5 questionnaires, and serum prostate specific antigen concentrations. Intraoperative blood loss and fluid absorption were evaluated by measuring serum hemoglobin and respiratory alcohol concentration. Patients were followed at 3 and 18 months with evaluation of clinical symptoms, flow rates, residual urine volumes, and complications.
  
  
  RESULTS
  There were no significant differences in blood loss, intraoperative fluid absorption, procedure time, or weight of the resected tissue between standard TURP and TUVRP with the various loops. No significant complications (infections, urethral stricture, reintervention) were seen.
  
  
  CONCLUSIONS
  In this comparison of the clinical outcome and morbidity of standard TURP versus different loops for TUVRP, there were no significant differences in any of the parameters evaluated.
