Abstract

Purpose: Acute myocardial infarction was found to be the main cause of increased long-term mortality in patients after transurethral compared to open prostatectomy in various retrospective studies. We performed a randomized prospective study to compare morbidity and incidence of acute myocardial infarction in patients after transurethral compared to open prostatectomy for benign prostatic hyperplasia. Materials and Methods: We studied 365 patients who were assigned to transurethral (236) or open (129) prostatectomy only according to the size of the prostate and who were followed for 7 to 8 years. The clinical status of the patients in both groups before and after the operation was compared, and the rate of myocardial infarction and long-term mortality was studied. Results: More patients with a history of cerebrovascular accident (5.4 versus 0.8%) and indwelling catheters (16.3 versus 7.6%) before the operation were in the open prostatectomy group. Among the 236 patients operated on transurethrally 31 were reoperated on (6 more than once) during followup compared to 4 of the 129 patients who underwent open prostatectomy. In 15 patients from the transurethral prostatectomy group myocardial infarction developed compared to 9 patients in the open prostatectomy group. This difference was not statistically significant. The rate of acute myocardial infarction after prostatectomy, no matter which approach was used, was greater than 6% and it appeared to be higher when compared to the rate of infarction in the general population of the same age group, which is approximately 2.5% in our county. There was no statistically significant difference in the overall mortality rate between the transurethral and open prostatectomy groups, which was 14.4 and 8.5% respectively. Conclusions: Open prostatectomy is more effective in overcoming urinary obstruction than the transurethral approach. No significant differences in myocardial infarction or overall mortality rates were found between the 2 groups.
