Tiivistelmä
AimsThe aim was to study the effect of intravesically instilled cis-urocanic acid (cis-UCA) on bladder function in an experimental rat model of acute bladder inflammation. Hyaluronic acid (HA) was used as a comparator compound.MethodsBladder irritation was induced in female rats by intravesical hydrochloric acid (HCl) infusion. Vehicle, 0.5% HA, or 2% cis-UCA solutions were infused intravesically twice a day for three consequent days. On the fourth day, urodynamical measurements were performed, the animals were sacrificed, and the bladders were removed for histopathological assessment.ResultsHCl treatment caused significant impairment of bladder function indicated by decreased micturition intervals and voided urine volumes and induced severe voiding dysfunction observed as occurrence of overflow incontinence. These functional changes were accompanied by increased bladder weight, hemorrhage, and infiltration of inflammatory cells into the urothelium. Intravesical cis-UCA treatment recovered bladder function by significantly prolonging the micturition interval, increasing the voided volume, and reducing the occurrence of overflow incontinence. All these changes were comparable to the effects of HA.ConclusionsIntravesical administration of cis-UCA was able to partially recover bladder function impaired by chemical irritation. Cis-UCA may offer a novel intravesical treatment option in some inflammatory conditions of the bladder. Neurourol. Urodynam. 35:786-791, 2016. (c) 2015 Wiley Periodicals, Inc.
