Abstract

A retrospective analysis of 108 patients who had undergone transurethral prostatectomy for benign prostatic hyperplasia between January 1988 and December 1992 was performed to evaluate risk factors influencing intraoperative and postoperative morbidity and mortality. Of 108 patients complications occurred in 32 cases, with the morbidity rate of 29.6% but no death occurred. The most common postoperative complication was bleeding in 9 cases(8.3%) followed by incontinence in 7 cases(6.5%), capsular perforation in 4 cases(3.7%), failure to void in 4 cases(3.7%) and urethral stricture in 4 cases(3.7%). Risk factors which increased the morbidity of transurethral prostatectomy were age greater than 75 years and the presence of associated medical disease(p<0.05) but a resection time of more than 90 minutes, weight of resected tissue more than 30 gram and amounts of irrigating solution of more than 20 L did not increase the postoperative morbidity significantly. In conclusion, meticulous preoperative and postoperative cares are necessary because poor general condition increase the postoperative complications and long-term, prospective randomized studies are required to evaluate risk factors influencing postoperative morbidity after transurethral prostatectomy.
