Description of intervention(s) / exposure
Insertion of TVT suburethral sling at time of prolapse repair. The TVT procedure (Gynecare, Ethicon Inc., Somerville, NJ) was performed as previously described by Ulmsten. The tape is passed from the vagina retropubically without tension. The tape is a permanent synthetic mesh. The procedure takes 10-15 min including cystoscopy to excluded any bladder perforation.
