[Urological investigation in women with stress incontinence prior and following anterior colporrhaphy and in control patients (author's transl)].

The pre-operative and post-operative findings in 56 patients with urinary stress incontinence are compared amongst each other and with the result of 24 continent control patients. The 56 patients were selected prospectively. The urethral closure pressure with stress and the stress quotient in urethral cystometry are significantly improved by the operations. The compliance as a cystometric criterium was significantly raised. The sizes of the angle in the urethrocystogram are at times significantly changed after operation. They are not lower than the values described in the literature. This shows good correlation with the results in the control groups, which have angles higher than those described in the literature. The time parameters of the uroflowmetry show prolongation after the anterior colporrhaphy. The times to the maximum, the waiting time, the urine flow time and the duration of micturition are longer. The mean volume of urine per second is not significantly changed. Our results are compared with other investigations. The findings in healthy continent women are considered to be possible parameters for a reference.
