Risk factors for complications and morbidity after radical retropubic prostatectomy.
OBJECTIVE
With recognition of the efficacy of surgical therapy for prostate cancer, there has been a marked increase in the number of radical prostatectomies performed, and substantial changes in surgical technique and perioperative management have decreased the morbidity of this procedure. We assessed the rate of perioperative complications with time and the risk factors for these complications, particularly age, operative time and co-morbidity.


METHODS
A detailed review of all medical records of a consecutive series of 472 patients treated with radical retropubic prostatectomy by 1 surgeon between 1990 and 1994 was performed to document any complication within 30 days postoperatively. American Society of Anesthesiologists (ASA) physical status classification recorded by the staff anesthesiologist was used as a standard index of co-morbidity.


RESULTS
Major complications were identified in 46 patients (9.8%), minor complications in 101 (21.4%) and none in 341 (72.2%). There were 2 deaths (0.42%). Major complications were not associated with age, operative time or year of operation but were significantly associated with ASA class (p = 0.006) and operative blood loss (p = 0.015) in a logistic regression analysis. Only 16% of patients were assigned to ASA class 3, yet this group included both deaths, a 3-fold increase in major complications, prolonged hospital stay, greater need for intensive care unit admission and more frequent blood transfusions. Major complications were almost 3 times more frequent in class 3 (21.3%) than in class 1 or 2 (7.6%) cases (p <0.005). Minor complications significantly increased hospital stay by a mean of 26% and major complications by 47% (p <0.0001).


CONCLUSIONS
Radical retropubic prostatectomy was performed with no perioperative complication in 72% of patients. Major complications resulted in more intensive use of medical resources and were related to co-morbidity rather than age.
