Impact of anatomical radical prostatectomy on urinary continence

Urinary continence following an anatomical approach to radical prostatectomy was evaluated in 593 consecutive patients, 547 (92%) of whom achieved complete urinary control. Stress incontinence was present in 46 patients (8%), of whom 34 (6%) wore 1 or fewer pads per day and 2 (0.3%) required placement of an artificial sphincter. No patient was totally incontinent. Age, weight of the prostate, prior transurethral resection of the prostate, pathological stage and preservation or wide excision of the neurovascular bundles had no significant influence on preservation of urinary control. These data suggest that anatomical factors rather than preservation of autonomic innervation may be responsible for the improved urinary control associated with an anatomical approach to radical prostatectomy.
