Bottom Line: BWT in DO group was significantly higher than that in the other groups (P < 0.005).The ROC revealed an area under the curve of 0.962 (95% CI, 0.90-1.01).DO patients have increased bladder wall thickness, lower first desire to void, and lower cystometric capacity.

ABSTRACT

Objective: To compare bladder wall thickness in two kinds of urinary incontinent women-stress urinary incontinence (SUI) and overactive bladder (OAB) with urodynamic detrusor overactivity (DO), and to compare them with continent patients by ultrasound, also, correlate with cystometric results in incontinent women.

Methods: 91 women were divided into the following groups: continent (n = 31), SUI (n = 30), and DO (n = 30) groups after clinical evaluation and urodynamic test (only in incontinent women). Transvaginal ultrasound was performed to the bladder wall thickness (BWT) measurement. The mean of BWT was calculated and data were analyzed with ANOVA and Turkey's multiple comparison tests. Pearson's correlation coefficient (r) was used to compare two variables. Receiver operating characteristic (ROC) curve was performed to study BWT as a diagnostic parameter.

Results: BWT in DO group was significantly higher than that in the other groups (P < 0.005). A moderate positive correlation was found between BWT and maximum bladder pressure during involuntary bladder contraction. There was no difference in BWT between SUI and continent groups. DO group had lower first desire to void and cystometric capacity. Maximum bladder pressure at detrusor contraction had a moderate positive correlation with BWT. The ROC revealed an area under the curve of 0.962 (95% CI, 0.90-1.01).

Conclusions: DO patients have increased bladder wall thickness, lower first desire to void, and lower cystometric capacity. There was a moderate correlation between BWT and maximum bladder pressure during involuntary bladder contraction.

Mentions: Concerning OAB group, there was a moderate positive correlation between BWT and maximum vesical pressure at involuntary detrusor contraction (r = 0.39, P = 0.017) (Figure 3). There was no significant correlation between BWT and first desire to void (r = 0.14, P = 0.242) and maximum cystometric capacity (r = −0.10, P = 0.308).
