Ten patients with urinary stress incontinence were treated by suburethral sling procedure using a polytetrafluoroethylene tube as the sling. The tension of suspension was determined by the post-urethrovesical angle measured by transrectal ultrasonography in each patient. In nine patients, the post-urethrovesical angle ranged from 90 to 110 degrees, and urinary continence of the patients was completely obtained. The remaining one patient whose post-urethrovesical angle was determined as 120 degrees could not obtain complete continence. None of the patients had subjective post-operative disturbance in urination and the peak flow rate of post-operative uroflowmetry hardly decreased in 7 patients in whom this was performed. Although post-urethrovesical angles reduced as the tension which suspended the bladder neck increased, the tension reforming the post-urethrovesical angle was various in each patient. Since one of the aims of suspension of the bladder neck for patients with stress incontinence is reform of the post-urethrovesical angles, correct and reasonable tension of suspension is to be obtained by measuring the post-urethrovesical angle.
