The Bonney test improves continence by supporting the vaginal wall, not direct compression. The Miyazaki-Bonney test may predict surgical success for stress incontinence.

Area of Science:

  • Urology
  • Female Pelvic Medicine and Reconstructive Surgery

Background:

  • Genuine stress urinary incontinence (SUI) is a common condition affecting many women.
  • Understanding the mechanisms of diagnostic tests for SUI is crucial for effective treatment.

Purpose of the Study:

  • To compare the effects of the Bonney test and direct urethral compression on urethral function.
  • To introduce and evaluate the Miyazaki-Bonney test as a modified diagnostic tool.

Main Methods:

  • Thirty-seven patients with genuine SUI underwent Bonney test, direct urethral compression, and Miyazaki-Bonney test.
  • Measurements included urethroscopy, cotton swab resistance, and urethral pressure profilometry.
  • Cough pressure transmission ratios were assessed before and during the Bonney test.

Main Results:

  • The Bonney test increased urethral pressure by 52 cm H2O; direct compression increased it by >250 cm H2O.
  • The Miyazaki-Bonney test showed minimal urethral pressure change.
  • Cough pressure transmission increased from 64% to 152% during the Bonney test; Miyazaki-Bonney test failed in 3/4 type III urethras.

Conclusions:

  • The Bonney test achieves continence by supporting the anterior vaginal wall, not direct urethral compression.
  • The Miyazaki-Bonney test mimics Burch bladder neck suspension and may predict surgical outcomes.
  • A standardized modified Bonney test is presented as the Miyazaki-Bonney test.
