Symptom analysis and uroflowmetry 7 years after transurethral resection of the prostate

The long-term result after transurethral resection of the prostate is not well documented. From 1981 to 1983, 84 consecutive consenting patients completed detailed symptom analysis and urodynamic examination before transurethral resection of the prostate. These studies were repeated 3 and 12 months postoperatively. Of the 84 patients 44 were interviewed at 86 months: 75% reported improvement compared to preoperative symptoms. In addition, 23 patients underwent uroflowmetry at 7 years. For this group the maximum urine flow rate remained virtually unchanged from 1 to 7 years postoperatively). When uroflowmetry results from all patients undergoing testing at the various followup intervals are considered, the maximum urine flow rate was 9.5 ml. per second preoperatively, 17.0 ml. per second at 3 months and 19.6 ml. per second at 1 year. Of the 44 patients 7 (16%) underwent repeat transurethral resection of the prostate.
