title: Transurethral resection of the prostate versus open prostatectomy: long-term mortality comparison.
abstract: To determine whether transurethral prostatectomy results in higher long-term mortality rates than open prostatectomy, we reviewed retrospectively 1,125 patients treated by transurethral and 190 treated by nonperineal open prostatectomy for benign disease at 1 institution from 1978 through 1987. Patients in whom prostatic cancer was found were excluded. We identified age, preoperative medical illnesses and urinary retention, American Society of Anesthesiologists category, type of anesthesia, length of followup, health status and cause of death. For statistical analysis the study cohort consisted of 527 patients in whom the charts were complete and followup was adequate (421 in the transurethral prostatectomy and 106 in the open prostatectomy groups). Mean age for the 2 groups was 66.3 and 67.5 years, respectively. With an average followup of 70.7 months 77% of the transurethral prostatectomy group were alive, compared to 78% of the open prostatectomy group at an average followup of 71.4 months. We found no supportive evidence that transurethral prostatectomy results in higher long-term mortality rates than does an open operation (log-rank test p = 0.74). Also, there was no significant survival difference in patients who required a preoperative Foley catheter. We also examined a subset of patients with adequate followup who had no significant medical history (for example hypertension, diabetes, heart disease and so forth) and compared them to patients with medical illnesses at prostatectomy. There was a significant survival difference between those with and without preoperative medical conditions (Wilcoxon test p = 0.047) in the transurethral prostatectomy group but not in the open group (p = 0.58). However, there was no significant survival difference between procedures among the healthiest subset of patients (p = 0.16).
