Urinary incontinence and genital prolapse: a prospective blind study of the value of urodynamic evaluation

The value of urodynamic examination was studied in 44 women treated for genital prolapse and/or urinary incontinence. A preoperative urodynamic examination was done but not considered in the planning of the operations. The treatment performed after clinical examination was identical to that proposed after urodynamic evaluation in 20 of 34 incontinent patients (59 per cent), while the treatments differed in 14 (41 per cent). The results were considerably better 6 months postoperatively in the former than in the latter patients. Of the 44 patients 11 (25 per cent) had detrusor instability, which resolved 6 months postoperatively in 4 and the symptoms had vanished or decreased in 6.
