Treatment of urinary incontinence with artificial urinary sphincter (report of 4 cases) / 中华泌尿外科杂志

ABSTRACT

Objective To explore the efficacy and safety of artificial urinary sphincter in the treatment of real urinary incontinence. Methods The implantation of AMS 800 sphincter prostheses was conducted on 4 patients with urinary incontinence.The voiding diaries were recorded and urodynamic examinations were done before and after the implantation.The adverse reactions were recorded after the procedure. Results In the 4 cases,the sphincter pump was activated 4 to 6 weeks after the implantation.The urinary incontinence was well controlled and automatic urination was recovered.No infection-related complication leading to failure of the artificial urinary sphincter occurred.Follow-up for 17 to 46 months showed no leakage of urine at daytime or at night. The mean score of quality of life was 1.Urodynamic examination showed satisfactory compliance and stability of the bladder.The urethral pressure profiles (UPPs) being 8.2 to 9.4 kPa (1 kPa=10.20 cmH 2O);and the mean was 8.7 kPa.Three cases had no residual urine,while only 1 case had 60 ml of residual urine.Only 1 patient had to change the control pump due to mechanical failure 27 months after the operation. Conclusions Artificial urinary sphincter implantation is an effective and safe therapy for real urinary incontinence.The proper use of AM 800 and improved technique result in good long-term outcomes.
