title: Percutaneous needle bladder neck suspension for the treatment of stress urinary incontinence in women: long-term results.
abstract: OBJECTIVE
  We evaluated the long-term results of percutaneous needle suspension using bone anchor devices for treating stress urinary incontinence in women.
  
  
  METHODS
  We retrospectively evaluated the long-term results of percutaneous bladder neck needle suspension performed at our institution. None of the women had undergone any anti-incontinence surgery before percutaneous needle suspension. A telephone survey was done for all available patients. Subjective cure was defined as no evidence of incontinence, significant improvement as 0 to 1 protective pad soaked daily and patient satisfaction with incontinence level, and failure as more than 1 pad used daily, lack of patient satisfaction or a secondary procedure required to treat stress urinary incontinence. In cases considered failures a detailed video urodynamic study was performed when possible before any secondary procedure.
  
  
  RESULTS
  In 1996 and 1997, 49 patients underwent percutaneous needle bladder neck suspension with bone anchors, of whom 42 (86%) were available for telephone interview. Mean patient age was 57 years (range 31 to 77) and mean followup was 29 months (range 16 to 52). As defined, subjective outcome in the 42 women was cure in 2 (5%), significant improvement in 5 (12%) and failure in 35 (83%). Of the 35 patients with treatment failure who did not undergo a secondary procedure 25 were asked to present for video urodynamics and 18 were evaluated. Urodynamics revealed demonstrable urinary incontinence, urethral hypermobility in 16 (88%), intrinsic sphincter deficiency in 1 (6%) and detrusor instability in 1 (6%). In 2 cases x-ray revealed that a bone anchor had dislodged and migrated into the pelvis. Serious osteomyelitis at the bone anchor site in 1 case required surgical débridement and 6 weeks of intravenous antibiotics.
  
  
  CONCLUSIONS
  Percutaneous needle suspension is associated with poor long-term results in women with stress urinary incontinence. Other procedures should be considered.
