Summary

Minimally invasive bone anchors show promise for female stress urinary incontinence (SUI) treatment. However, needle suspension techniques require significant improvement to reduce high recurrence rates and enhance effectiveness.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Female stress urinary incontinence (SUI) significantly impacts quality of life.
  • Current surgical treatments for SUI vary in efficacy and invasiveness.

Purpose of the Study:

  • To evaluate the technical feasibility and clinical outcomes of bone fixation techniques combined with needle suspension for SUI correction.
  • To identify limitations of current suspension methods and explore potential improvements.

Main Methods:

  • Utilized a screw-like bone anchor inserted into the pubic tubercle for minimally invasive fixation.
  • Employed needle suspension techniques, including deep Z-stitching in paraurethral tissue.
  • Investigated modifications such as four-point suspension, laparoscopic dissection, and combination with sling procedures.

Main Results:

  • Bone anchors demonstrated stability and reliability.
  • Initial needle suspension techniques resulted in a high 1-year recurrence rate (76%) due to suture pull-through.
  • Modified suspension techniques showed significantly improved short-term results.

Conclusions:

  • Bone anchors are a viable option for minimally invasive bladder neck suspension fixation.
  • Improvements in suspension techniques are crucial for reducing SUI recurrence rates.
  • Further refinement of suspension methods is needed to optimize outcomes for SUI treatment.
