title: Tension-free vaginal tape surgery for stress urinary incontinencne: a prospective multicentered study in Japan.
abstract: OBJECTIVE
  To report the prospective multicentered study of the tension-free vaginal tape (TVT) procedure for stress urinary incontinence.
  
  
  METHODS
  One hundred and fifty-one women with stress urinary incontinence were operated on by the TVT procedure and were followed up at 3, 12, and 24 months after surgery. Patients' age and body mass index (BMI) averaged 57 years and 23.9, respectively. Forty-nine women were classified as type I, 46 women type II and 56 women type III (McGuire's classification). Local anesthesia was used in the operations on 137 women (91%) and epidural or general anesthesia was used in 14 (9%). Surgical outcomes were analyzed with Kaplan-Meier survival curves.
  
  
  RESULTS
  The subjective and objective cumulative cure rates 24 months later were 92% and 77%, respectively (P > 0.05). The TVT operation for women with type III (62%) resulted in a significantly lower cure rate compared to those with type I or with type II (83%) (P < 0.001). Post-operatively a urethral catheter was indwelt one day in 77 women (51%), two days in 14 (9%) and 3-7 days in 60 (40%). Surgical complications were encountered in 43 women (28%). The most frequent was bladder perforation in 24 women followed by postoperative difficulty in urination and de novo urgency.
  
  
  CONCLUSIONS
  The TVT surgery was promising for the treatment of stress incontinence because of minimal surgical invasiveness and satisfactory surgical results. Women with type III incontinence resulted in fewer satisfactory outcomes than those with type I or II incontinence.
