Аннотация:Abstract Ten women undergoing a polypropylene suburethral sling procedure for treatment of genuine stress incontinence were assessed pre‐ and post‐operatively by standard urodynamic methods and by urethral pressure profile measurements at rest and on stress. Eight patients were subjectively and seven objectively cured of stress incontinence. A significant reduction in urine flow rate was found although this appeared to be of little relevance to the successful outcome of surgery. An increase in resting urethral profile length was seen in both successful and unsuccessful cases. The former also had an improvement in maximum urethral closure pressure on stress due to improvement in pressure transmission in the proximal three quarters of the functional urethral length. The urethra appeared relocated in a retropubic position following successful and unsuccessful operations. It is likely that failure was associated with periurethral fibrosis causing failure of pressure transmission despite adequate elevation.
