Basic urodynamic tests (cystomanometry-sphincterometry) are absolutely necessary for evaluation of urinary incontinence, urination disorders and prolapses, and are useful in the evaluation following treatment. In a retrospective study including 700 cases, the authors analyze the urodynamic results according to the clinical symptomatology since the clinical diagnosis often is misleading. Then, they study the different treatments advocated and their clinical and urodynamic results: medical treatment: 75 per cent of good results; pelvi-perineal physical therapy: 82 per cent of good results; Loffredo's procedure: 98.5 per cent of good results; Marion's procedure for potential EBI: 92.5 per cent; for obvious EBI: 89 per cent.
