Transurethral prostatectomy: immediate and postoperative complications. A cooperative study of 13 participating institutions evaluating 3,885 patients.

The mortality rate for transurethral prostatectomy was 0.2 per cent in 3,885 patients reviewed retrospectively. The immediate postoperative morbidity rate was 18 per cent. Increased morbidity was found in patients with a resection time of more than 90 minutes, gland size of more than 45 gm., acute urinary retention and patient age greater than 80 years, and in the black population. Of the patients 77 per cent had significant pre-existing medical problems. Operative mortality, significant morbidity and hospital stay were reduced in comparison to studies done 15 and 30 years ago.
