A urethral stricture is a narrowing of the urethra, the tube connected to the bladder that allows urination. The narrowing reduces the flow of urine and makes it more difficult or even painful to empty the bladder. [1] Urethral stricture is caused by injury, instrumentation, infection, and certain non-infectious forms of urethritis. The ...
These include vesicoureteral reflux, urethral stricture, and stenosis. The most common cause of hydronephrosis in young adults is kidney stones . In older adults, the most common cause of hydronephrosis is benign prostate hyperplasia (BPH), or intrapelvic neoplasms such as prostate cancer .
Ureteric stricture (ureteral stricture) is the pathological narrowing of the ureter which may lead to serious complications such as kidney failure. Pathophysiology [ edit ]
It is also sometimes called a stricture (as in urethral stricture). [3] Stricture as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g. achalasia, prinzmetal angina); stenosis is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g. atherosclerosis). [4]
Treatment is typically with a catheter either through the urethra or lower abdomen. [1] [3] Other treatments may include medication to decrease the size of the prostate, urethral dilation, a urethral stent, or surgery. [1] Males are more often affected than females. [1] In males over the age of 40 about 6 per 1,000 are affected a year. [1]
Renal colic, also known as ureteric colic, is a type of abdominal pain commonly caused by obstruction of ureter from dislodged kidney stones.The most frequent site of obstruction is the vesico-ureteric junction (VUJ), the narrowest point of the upper urinary tract.
Chronic ischemic colitis is often treated with surgical removal of the chronically diseased portion of the bowel. [citation needed] A colonic stricture is a band of scar tissue which forms as a result of the ischemic injury and narrows the lumen of the colon. Strictures are often treated observantly; they may heal spontaneously over 12–24 months.
The total removal of the colon, called a colectomy or resection of affected parts of the colon may be needed if part of the gut dies (for instance toxic megacolon), or if there is a localized area of dysmotility. Gastric and colonic pacemakers have been tried. These are strips placed along the colon or stomach which create an electric discharge ...
