title: Urodynamic and clinical assessment of the Lyodura sling operation for urinary stress incontinence.
abstract: A Lyodura sling operation for urinary stress incontinence was performed on 36 patients. The success rate was 89%, when success was defined as absence of objective urine loss at coughing or straining, with full bladder in the upright position and during a Urilos test, at least 6 months after surgery. Full urodynamic assessment, including urethral rest and stress profiles, were performed before, and 6 months after, surgery. Success of the operation depended mainly on enhancement of urethral pressure transmission. Functional length of the urethra and maximal urethral pressure did not influence the success rate. The procedure is especially suitable in patients with some degree of uterine or vaginal prolapse.
