[Urometric studies before and after stress incontinence operations]

77 women with insufficiency of the urethral sphincter were urometrically examined before and 16 weeks after operations for urinary stress incontinence (38 vaginal plastic operations and 39 Zoedler plastic operations). The resting pressure in the urethra cannot be increased by either operation. On the contrary, the readings are lower after the operations. A slight increase in the functional length of the urethra is to be observed only in the case of Zoedler plastic operations. The so-called stress quotient shows the clearest change. This increases in both groups and corresponds to clinical healing. The results are compared with more recent, partly divergent findings.
