The application discloses application of metformin in preparation of a medicine for treating interstitial cystitis, and finds that metformin can reduce pain sensitivity of an interstitial cystitis (IC) rat, reduce edema degree of a bladder of the IC rat, restore bladder capacity of the IC rat, repair the bladder mucosa of the IC rat and reduce submucosal hemorrhage, reduce mast cell infiltration, and has a significant curative effect on interstitial cystitis, and can provide a new medicine for treating interstitial cystitis.

Methods and systems for ultrasound-based urodynamic evaluation are presented in the present disclosure. Pre-void and post-void ultrasound data of a bladder is acquired, in addition to a dynamic acquisition during voiding on a sagittal plane that encompasses the bladder, bladder neck and proximal urethra. The dynamic acquisition may be an ultrasound cine scan or a uroflowmetry measurement during voiding. Using semiautomatic segmentation, the volumes are quantified and virtual models are generated. Similarly, the ultrasound cine sagittal images are segmented to determine the deformation pattern of the bladder during voiding. Using an algorithm, a volume interpolation between pre and post void volumes is performed using the deformation profile obtained from the dynamic sagittal images as a constraint. Resolved bladder volumes are then analyzed using a computational fluid dynamics algorithm to derive flow rates and pressures and to calculate indices of contractility (BCI) and bladder obstruction (BOOI).
