Large sliding inguinal hernias involving the urinary bladder are rare. We present the relevant clinical data, radiographic images, and the intraoperative findings of a sliding inguinoscrotal herniation of the urinary bladder. A 67-year-old male presented with a scrotal mass and the need to manually compress his scrotum in order to void. Diagnosed with a large sliding inguinal hernia with significant bladder involvement (scrotal cystocele), the patient underwent an inguinal herniorraphy and replacement of the bladder in the retroperitoneal space. Surgery proved to be successful in the management of the inguinal hernia and voiding dysfunction.

To further characterize colonic motility in the dog and to examine the effects of intraluminal contents, motor activity in conscious animals was recorded by perfused intraluminal catheters. Animals were studied first with the bowel intact and, later, the colon was fashioned into an isolated loop. In the fasting state, cycles of motility recurred approximately each 30 min. These consisted of sequences of phasic contractions (bursts) that migrated variable distances in either direction; stationary bursts were also recorded. The fasting patterns recorded from intact bowel and isolated loops were not different. Feeding increased colonic motility, and the mean periodicity of cyclic bursts was reduced significantly to approximately 20 min. Moreover, differences were observed between intact bowel and isolated loops in the postprandial period. Diversion of chyme from the colon significantly reduced the motor response to food, but only in the late (2-4 hr) postprandial period, when the less frequent, fasting cycle returned to the loops. Perfusion of isolated loops with chyme or saline reestablished the postprandial pattern seen in intact bowel. The results suggest that the volume, but not the composition, of luminal contents modify postprandial motility in the canine colon. Additional experiments confirmed that, in particular, volatile fatty acids were probably not important determinants of colonic motility in the dog.
