The present study aims to evaluate and compare the alteration of bladder function according to varying degrees of cystocele by using the urodynamic study results.
This study included 86 women with cystocele who underwent urodynamic study. The patients were classified into four grades according to pelvic organ prolapse quantification of the International Continence Society. Variables such as bladder capacity, maximum detrusor pressure (Max-Pdet), maximum flow rate (Qmax), and postvoiding residual volume (PVR) were investigated and were compared between each cystocele grades.
The only variable showing a significant difference between the cystocele grades was PVR (p <0.001, Table 1). Especially, a significant difference regarding PVR was presented between grade I and III, I and IV, and II and IV (Figure 1). Additionally, PVR was positively correlated to cystocele grade (r=0.50, p<0.001; Table 2).
Postvoid residual tends to increase significantly with the increase of cystocele severity.
