[Improvements in surgical therapy of incontinence--failed outcome!].

The general advances made in minimal invasive surgery in the last 15 years has also led to the introduction of several new techniques for treating female incontinence. In the further development of bladder neck suspension according to Stamey-Pereyra, the use of miniature bone anchors received considerable support. Bladder neck suspension according to Stamey-Pereyra yields good initial results with a low complication rate but achieves permanent continence in only 40-71%. The anterior percutaneous implantation of miniature bone anchors with the attached suspension effects continence rates between 24% and 94%. Healing rates for transvaginal application of miniature bone anchors range from 52% to 100%. Reactions to foreign bodies are particularly common with synthetics but also occur with autologous materials. They are often associated with detrusor instability or sensory urge symptoms. Though these minimally invasive techniques can reduce the severity of stress incontinence, long-term healing is only achieved in about half the cases. The techniques described appear to be particularly unsuitable for treating grade III stress incontinence. The morbidity is unacceptable, especially when synthetic material is used in combination with bone anchors. Impaired vaginal wound healing often occurs in conjunction with irritative symptoms.
