An abnormal passage in the URINARY BLADDER or between the bladder and any surrounding organ.

A musculomembranous sac along the URINARY TRACT. URINE flows from the KIDNEYS into the bladder via the ureters (URETER), and is held there until URINATION.

Abnormal communication most commonly seen between two internal organs, or between an internal organ and the surface of the body.

Tumors or cancer of the URINARY BLADDER.

Pathological processes of the URINARY BLADDER.

An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.

An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).

An abnormal passage or communication leading from an internal organ to the surface of the body.

Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.

An abnormal passage or communication between a bronchus and another part of the body.

An abnormal passage in any part of the URINARY TRACT between itself or with other organs.

An abnormal passage between two or more BLOOD VESSELS, between ARTERIES; VEINS; or between an artery and a vein.

An abnormal anatomical passage connecting the RECTUM to the outside, with an orifice at the site of drainage.

A pouch or sac developed from a tubular or saccular organ, such as the GASTROINTESTINAL TRACT.

Pathological processes involving the URETHRA.

Insertion of a catheter into the urethra to drain the urine from the bladder at intervals as needed.

A congenital abnormality characterized by the outpouching or sac formation in the ILEUM. It is a remnant of the embryonic YOLK SAC in which the VITELLINE DUCT failed to close.

Saccular protrusion beyond the wall of the ESOPHAGUS.

Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)

A pouch or sac opening from the COLON.
