Morbidity of radical perineal prostatectomy following transurethral resection of the prostate.

Radical prostatectomy in patients who have had prior transurethral resection of the prostate has been reported to result in significant morbidity. From 1974 to 1982, 30 patients who had had previous transurethral resection of the prostate underwent radical perineal prostatectomy for localized prostatic cancer. Operative time and blood loss were similar to a group of patients who had not had prior transurethral resection of the prostate. Over-all, 3 patients (10 per cent) had total incontinence and 3 (10 per cent) had stress incontinence requiring a pad or device. No patient undergoing radical prostatectomy less than 4 weeks or more than 4 months after transurethral resection of the prostate had postoperative incontinence. When radical perineal prostatectomy was performed between 4 weeks and 4 months after transurethral resection of the prostate the incidence of incontinence was 50 per cent. Five patients experienced prolonged perineal urinary drainage, all but 1 of whom healed spontaneously. Of the 6 patients with incontinence 3 had prolonged drainage. No patient had a rectal injury and there was no operative mortality. Two patients died without cancer and 1 has evidence of disease recurrence. We conclude that radical prostatectomy may be performed safely with acceptable morbidity following transurethral resection of the prostate and that if 4 weeks has elapsed since resection it might be advantageous to wait 4 months before performing radical surgery to lessen the risk of incontinence.
