- Abstract
Aims The role of urodynamic study ( UDS) in diagnosis of interstitial cystitis/bladder pain syndrome ( IC/ BPS) remains inconclusive, nor has the predictor for a treatment success been elucidated. We evaluated the diagnostic and prognostic values of UDS in patients with IC/ BPS. Materials and methods IC/ BPS patients with complete data of a symptom assessment, video UDS, potassium chloride ( KCl) test, cystoscopic hydrodistention and treatment records were reviewed retrospectively. O'Leary-Sant symptom index and problem index ( ICSI, ICPI) were available in part of the patients. The associations between UDS parameters with symptom scores, KCl test result, cystoscopy findings and treatment outcome were analysed. The UDS parameters, including first sensation of filling ( FSF), first desire to void ( FD), strong desire to void ( SD), cystometric bladder capacity ( CBC), maximum flow rate (Qmax), detrusor pressure at Qmax (Pdet), voided volume ( VV) and postvoid residual ( PVR). Univariate and multivariate logistic regression analyses were used to identify the variable predicting treatment success. Results A total of 214 IC/ BPS patients were enrolled in this study. The mean volumes at FSF, FD, SD, CBC and VV were inversely correlated with ICSI and ICPI (all p < 0.05). The patients with a positive KCl test had significantly lower mean volumes at SD, CBC, VV and lower Qmax (all p < 0.05). Significantly lower mean volumes for FSF, FD, SD, CBC and VV were found in patients with higher grade of glomerulation under cystoscopy (all p < 0.01). The anaesthetic maximal bladder capacity ( MBC) was positively correlated with FSF, FD, SD, CBC, Qmax and VV (all p < 0.01). Female gender and the volume at SD were found to be the independent predictors for treatment outcome. Conclusions Our study demonstrated that there might be a role of UDS to help in diagnosis and prognostication for IC/ BPS. Future prospective investigations are warranted.
