[The diagnostic value of combined urodynamic study in different forms of urinary incontinence in women]

Diagnostic potential of urodynamic tests was studied in 279 females with combined and complicated enuresis. 90 healthy females and 21 cadavers served control. The statistical analysis covered the following urodynamic parameters: cystometric volume, detrusor pressure in cystometric volume, functional urethral length, maximal intraurethral pressure, fluctuations of maximal intraurethral pressure. Isolated measurements of cystometric volume, functional urethral length and maximal intraurethral pressure failed to provide sufficient diagnostic information in effort enuresis, whereas cystometry was most efficient in diagnosis of detrusor instability. Registration of urethral pressure fluctuations in the maximal point allows detection of urethral instability. Combined urodynamic examination can not be fully rejected in patients with complicated and combined enuresis.
