THE RELIABILITY OF URODYNAMIC ASSESSMENT IN CONFIRMATION OF STRESS URINARY INCONTINENCE IN RELATION TO BONNEY TEST

Abstract

According to the International Continence Society, stress (static) urinary incontinence is defined as any involuntary loss of urine on effort or physical exertion, due to which intravesical pressure overcomes urethral pressure, with no detrusor activity. Urodynamic testing accurately assesses the function of the bladder and urethra. The urodynamic assessment includes three tests: cystometry, uroflowmetry and profilometry (determination of urethral pressure profile). Prior to urodynamic assessment, it is mandatory to rule out urinary tract infection since it is an invasive test. Urethral profilometry is a technique that measures pressure in the urethra and bladder at rest, during stressful actions, and during the act of miction. Its main purpose is to evaluate the sphincter mechanism. During the examination, a special catheter is used, which is being slowly pulled out from the bladder neck throughout the urethra, with continuous recording of intraurethral pressure. In addition to measuring urethral pressures, stress urinary incontinence is also very successfully proven by the cough test and Bonney test. If, on forced cough, the urine escapes uncontrollably, and continence is restored by finger lifting the neck of the bladder, the diagnosis of static incontinence is confirmed. At our urogynecologic clinic, urodynamic examination is being routinely performed. In the present study, we included patients previously treated for urinary stress incontinence and compared their results of urodynamic assessment to the results of Bonney test. Of the 43 subjects in whom stress incontinence was proven with Bonney test, we recorded an appropriate profilometry result in 13 cases.
