Objective: A prospective trial to determine the effect of the extent of tissue resection on symptom improvement after transurethral resection of the prostate in men with symptomatic benign prostatic enlargement and to evaluate any potential correlation between prostate size and outcome, a new variable the residual prostatic weight ratio (RPWR) Patients and Methods: From October 2002 to November 2003, a total of 50 patients (mean age 62.6 yrs., range 50-91) with symptomatic benign prostatic enlargement who underwent TURP participated in this prospective study. Patients were assessed preoperatively with the American Urological Association symptom Score, Urinary flow rate measurements (Qmax and Qavg) as well as prostate volumes by transabdominal ultrasound. The amount of tissue resected was weighted. RPWR was derived by dividing the weight afterTURP by the initial weight. Clinical outcome was evaluated by the difference in AUA score, Qmax and Qavg before and 2 months after Surgery. Results: There was a significant improvement in AUA score, Qmax and Qavg postoperatively. Maximum numbers of patients undergoing TURP had RPWR in the range of 5160% (mean RPWR 49.9%). Mean overall change in AUA Score (DAUA), D Qmax and D Qavg was 12.04, 8.27 ml/sec and 6.64 ml/sec respectively. Smaller the RPWR larger is the DAUA, DQmax, DQavg and vice versa. There was negative correlation between the RPWR and the DAUA, DQmax and DQavg (r = -0.42, -0.067, and -0.09 respectively). Conclusion: Symptomatic improvement after TU RP will depend on the amount of tissue removed and the smaller the RPWR after TU RP the better the clinical outcome.
