This experiment was designed to define decreasing effect of intravesical pressure by ultrasound therapy on distended bladder of rabbit in vivo. Thereby we suggest and strengthen the basis for the clinical application of ultrasound therapy on hyperreflexic detrusor.

Eighteen normal male rabbits were used. Intravesical pressure at 5 minutes in ultrasound therapy group was significantly decreased, and intravesical temperature in the group was significantly higher than control group(p0.05). While the differences of the pressure and temperature at 10 minutes were not significant between the groups.
