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 ...
The protection provided by the foreskin for the glans penis and meatus has been recognized since 1915. In the absence of the foreskin the meatus is exposed to mechanical and chemical irritation from ammoniacal diaper (nappy) that produces blister formation and ulceration of the urethral opening, which eventually gives rise to meatal stenosis (a narrowing of the opening). [1]
Treatment, depending on cause, may require prompt drainage of the bladder via catheterization, medical instrumentation, surgery (e.g., endoscopy, lithotripsy), hormonal therapy, or a combination of these modalities. [citation needed] Treatment of the obstruction at the level of the ureter: Open surgery. Less invasive treatment: laparoscopic ...
Urethral stents or urethral sphincterotomy are other surgical approaches that can reduce bladder pressures but require use of an external urinary collection device. [11] Urethral slings may be used in both adults and children [12] [13] [14] Artificial Urinary Sphincters have shown good term outcomes in adults and pediatric patients.
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]
Urinary tract obstruction is a urologic disease consisting of a decrease in the free passage of urine through one or both ureters and/or the urethra. It is a cause of urinary retention. Complete obstruction of the urinary tract requires prompt treatment for renal preservation. [1]
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]
A meatotomy (/ m iː ə ˈ t ɒ t əm ɪ / [1] [2]) is a form of penile modification in which the underside of the glans is split, extending the urinary meatus.The procedure may be performed by a doctor to alleviate meatal stenosis or urethral stricture.
