Introduction: There arecurrently no studies that have investigated the relationship offemale urethral length with SUI, which is the reason why we haveperformed this study.
Objective: To evaluate theassociation between female urethral length and urodynamic study (UDS)parameters in stress urinary incontinence (SUI).
Methods:We reviewed the clinical records of 391 women who werediagnosed with SUI. The patients underwent a physical examination andUDS. Uroflowmetry data included the maximal flow rate (Qmax), time toQmax, voided volume and post-void residual urine volume (PVR).Filling cystometry data included the first strong desire to void,valsalva leak point pressure (VLPP) and cough leak point pressure(CLPP). The Maximal urethral closure pressure (MUCP) and functionalurethral length (FUL) was measured by urethral profile from UDS. Andthe anatomical urethral length (AUL) was measured using Foleycatheter. In order to determine a "actual urethral length",we calculated FUL/AUL ratio for this study.
Results: Atotal of 299 patients were included in our study. The mean patientage was 57.73 ± 10.18 years. The mean AUL and FUL were 26.89 ± 4.50mm and 32.20 ± 16.09 mm, respectively. In Pearson correlationcoefficients, FUL/AUL ratio correlated with PVR (-0.064, p= 0.270),VLPP (0.193, p=0.001), CLPP (0.119, p=0.040) and MUCP (0.249.p=<0.001). Multivariate analysis revealed that FUL/AUL ratio (HR2.452, p=0.001) and MUCP (HR 1.131, p=0.012) were significantlyassociated with success of surgery.
Conclusions: Ourresults showed that female urethral length was associated with UDSparameter of SUI. Also it can be used as a significant predictivefactor for a successful surgery.
