[The importance of the sphincterometric parameters using microtip-transducers and of the urilos-nappy-test for the investigation of female urinary incontinence (author's transl)].
The value of the patient's history, the nappy-test (urilos meter) and urethro-cystometry with microtip-transducers was analized in 125 "stressincontinent" women. We consider the results of the nappy-test together with urine loss during coughing in the erect position as an objective evidence of incontinence. On this basis, two groups of patients were formed which allowed that statistical comparison of the different urethro-cystotonometric parameters. The urethral closure pressure under stress (urethral stress profile) is still the best criterium for the diagnosis of an urethral insufficiency. We studied especially the urethral closure pressure at rest and the pressure transmission from the bladder to the urethra. Although we could prove that both these parameters were statistically more often altered in cases of "proven" incontinence (urine loss when erect and positive nappy-test) than in cases without "proven" incontinence (no urine loss when erect and negative nappy-test), the lower limits of normal could not be determined because of the broad range of confidence. The diagnostic and therapeutic consequences are discussed.
