Puboprostatic sling repair for treatment of urethral incompetence in adult neurogenic incontinence.

ABSTRACT

PURPOSE: An incompetent urethral sphincter can be a significant factor contributing to urinary incontinence in patients with neurogenic bladders. We review our experience with 12 men who underwent a puboprostatic sling. MATERIALS AND METHODS: The study included 12 men (mean age 37.1 years) with neurogenic bladder due to spinal cord injury in 9 and spina bifida in 3. All patients were diagnosed with urethral incompetence based on fluorourodynamic evaluation. Medical therapy failed in all 12 patients and all complained of urine leakage with activity. All patients underwent placement of an autologous fascial sling distal to the prostatic urethra via an abdominal approach. Ten patients also underwent simultaneous bladder augmentation to correct high intravesical pressures. RESULTS: Followup ranged from 1 to 39 months (average 14.25). All patients manage the bladder with intermittent catheterization. Of the patients 8 are completely dry between catheterizations and 2 had significant improvement with only minimal leakage (1 pad per day), with an overall success rate of 83%. One patient improved initially but subsequently underwent placement of an artificial urinary sphincter for residual stress incontinence. In 1 patient several external sphincterotomies failed despite adequate sling placement. There were no complications related to the placement of the sling and all patients are able to perform intermittent catheterization without difficulty. CONCLUSIONS: In select male patients the puboprostatic sling can be an effective and safe method to treat urethral incompetence secondary to neurogenic voiding dysfunction.
