Urodynamic in the diagnosis and treatment of urinary stress incontinence

The authors examine the role of the urodynamic test on patients suffering from stress incontinence. The simultaneous recording of the flowmetry and of bladder and urethral pressures continues to be the most efficient method for the functional demonstration of urinary incontinence. According to the authors, however, it is necessary to evaluate, before the operation, the suitability of the bladder for surgical intervention to avoid any voiding disorders which might occur following surgery. The cystosphinctermanometry with simultaneous flowmetry, together with the stop test, allows for a precise analysis of the particular voiding habit of each bladder, thus permitting an evaluation of the two essential parameters for surgical treatment; bladder capacity, and the characteristics of the detrusor contractability.
