We experienced 9 cases of percutaneous bladder neck stabilization (Vesica) for patients with urinary incontinence who were diagnosed with stress incontinence from December 1995 to June 1998. None of the patients were able to control continence with any drugs. Chain cystography was performed on all of the patients before and after surgery. The posterior urethro-vesical angle before surgery was over 130 degrees in all of the patients, and it improved after the operation. Moreover, the mean volume of the pad test greatly decreased from 47 g to 1 g. All of the patients were treated with epidural anesthesia. The operation time was less than 60 minutes. The subjective and objective findings were satisfactory. We conclude that percutaneous bladder neck stabilization is a very useful surgical treatment for stress incontinence.
