The comparison of urodynamic findings in women with various types of urinary incontinence

We aimed to determine the differences of the urodynamic findings of mix urinary incontinence (MUI), urge urinary incontinence (UUI), and stress urinary incontinence (SUI), and to evaluate the urodynamic findings in different groups by using bladder sensitivity index (BSI).

The data of 99 patients who underwent urodynamic testing related to the suspicion of SUI, UUI or MUI were analysed. This analysis included a retrospective evaluation of patients' cards, voiding diaries, and urodynamic reports. At filling cystometry, the parameters of first sensation of bladder filling (FSBF), first desire to void (FDV), strong desire to void (SDV), and bladder capacity (Vmax), which were related to the bladder sensation, were determined. Subsequently, uroflowmetric findings were recorded during bladder emptying. BSI was defined as the ratio of Vmax/ FDV. These results were statistically compared among the goups.

The sample included 35(35.5%) MUI, 33(33.3%) UUI and 31 (31.1%) SUI. The mean ages were similar in all groups (P = 0.868). The mean FSBF, FDV, SDV and Vmax values were significantly different among groups (p = 0.004, p < 0.001, p < 0.001, p < 0.001 respectively). Nevertheless, there was no statistically significant difference among the mean daily voiding accounts (P = 0.005). Although the mean maximum flow rate (Qmax) values were similar (P = 0.428), the mean maximum detrusor pressure (Pdet(max)) values were significantly different (P = 0.021). The mean BSI values showed no significant differences (P = 0.097).

It was concluded that while the use of urodynamic testing could contribute to the management of urinary incontinence, the indexes including BSI requere more detailed and comprehensive studies.
