Background:The aim of the study was to evaluate differences in urodynamic findings in women with urinary incontinence between subjects with or without intrinsic sphincter deficiency (ISD).
Material/Methods: Sixty consecutive female patients with a history and urodynamically confirmed diagnosis of pure urinary incontinence were evaluated. Patients were divided into two groups according to their abdominal Valsalva leak-point pressure (AVLPP) values using a cutoff of 60 cm H[sub]2[/sub]O: group A patients with AVLPP ≤60 cm H[sub]2[/sub]O and group B patients with AVLPP >60 cm H[sub]2[/sub]O.
Results: Qmax and Qave in group A were higher than in group B; flow time was significantly shorter in group A than in group B. PVR in group A was lower than in group B. In pressure flow study, all detrusor findings in group A had a pressure value lower than in group B. MUCP in patients with AVLPP ≤60 cm H2O was significantly lower than in group B, but the degrees of specificity and sensitivity in group A and B were 90% and 43.3%, respectively.
Conclusions:The results of this study confirm a more efficient bladder emptying in patients with AVLPP ≤60 cm H[sub]2[/sub]O.
