Methods: Vesical pressure measurement

during the continuous infusion of the urinary bladder with saline, acetic acid (AA, 0.1%) or IWR1 prostaglandin E2 (PGE2, 10−5 M) were performed in un-anesthetized rats. Multi-unit recording from bladder afferent nerves preformed under urethane anesthesia. Laser irradiation, either continuously at 1 W or in 10 W-pulse mode, was delivered at 830 nm from 1.5 cm above the skin at the lumbosacral joint. Results: During continuous saline infusion to the urinary bladder, neither continuous (1 W) nor pulse (10 W) laser irradiation altered the intercontraction interval and nerve firing during distention of the bladder. Pulse laser, but not continuous laser irradiation, increased the intercontraction interval with AA or PGE2 infusion and diminished nerve firing during distention

of the bladder with AA or PGE2 infusion. Conclusion: These data indicate that pulse laser could diminish inflammation related nerve firing from the bladder. Since this laser irradiation did not affect the normal bladder distention elicited nerve firing, it appears capable of reducing urgency sensation without loss of the basic micturition reflex. “
“Objectives: To compare the effectiveness and safety of solifenacin versus propiverine in the treatment of overactive bladder (OAB), in a single-blind, randomized parallel study. Methods: Sixty-six patients with OAB (14 men and 52 ABT-263 nmr women) were randomly assigned to groups: solifenacin (5 mg/day) or propiverine (20 mg/day) and treated selleckchem for 8 weeks. The primary outcome variable

was mean change from baseline to end of treatment in urgency of the OAB symptom score (OABSS). Secondary outcomes were bladder diary variables: change over 24 h in the mean number of voids (daytime and nighttime), episodes of micturition urgency and incontinence, and mean volume voided. Patients also completed total OABSS and the King’s Health questionnaires. Results: Group backgrounds were comparable except for the male to female proportion; 11:22 for solifenacin (n = 33) versus 3:30 for propiverine (n = 33). Adverse events were 6 of 29 (21%) for solifenacin versus 14 of 26 (54%) for propiverine (P = 0.017). Three patients were withdrawn for voiding difficulty (one in solifenacin and two in propiverine) and one patient for dry mouth (propiverine group). Change in OABSS urgency score was −2.3 ± 1.4 for solifenacin (n = 28) versus −1.3 ± 1.7 for propiverine (n = 23), (P = 0.0169). Total OABSS and other individual scores, and voiding diary parameters for both drugs showed improvements; however, between-group difference was not established. Conclusion: Although both solifenacin 5 mg and propiverine 20 mg were effective in the treatment of OAB, solifenacin appeared to be more effective and tolerable.
