bladder perforation
usually the result of obstructive urolithiasis with eventual leakage of urine into the peritoneal cavity. See also congenital urinary bladder rupture.
eardrum perforation
occurs when an infectious process erodes the tympanic membrane or leads to increased pressure in the middle ear.
esophageal perforation
causes local cellulitis and obstruction of the esophagus.
gallbladder perforation
sometimes occurs as a complication of cholecystitis and gallstones. When the gallbladder is infected, necrosis may progress to the point of destroying the wall so that the bile spills out into the abdominal cavity causing biliary peritonitis.
intestinal perforation
a complication of ulcerative colitis (see colitis), intestinal obstruction, ulceration and other disorders in which there is inflammation of the intestinal wall or obstruction of the intestinal lumen.
ulcer perforation
a complication of duodenal and gastric ulcers. It requires immediate surgical correction to prevent hemorrhage, shock and peritonitis.
urethral perforation
is usually a result of obstructive urolithiasis; urine collects in a ventral subcutaneous site.
