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).

Damage to the urethra, such as by kidney stones, chronic infection, cancer, or from catheterisation, can lead to narrowing, called a urethral stricture. [24] The location and structure of the narrowing can be investigated with a medical imaging scan in which dye is injected through the urinary meatus into the urethra, called a retrograde ...
Urethral syndrome is defined as symptoms suggestive of a lower urinary tract infection but in the absence of significant bacteriuria with a conventional pathogen. [1] It is a diagnosis of exclusion in patients with dysuria and frequency without demonstrable infection. [2] In women, vaginitis should also be ruled out. [3]
Urethroplasty is regarded as the gold standard treatment for urethral strictures and offers better outcomes in terms of recurrence rates than dilatations and urethrotomies. It is probably the only useful modality of treatment for long and complex strictures though recurrence rates are higher for this difficult treatment group. [1]
Urethral sounding is the practice of inserting objects (typically made by metal or silicone) into the urethra for sexual gratification. [1] Urethral dilatation is a urological procedure that uses probes called sounds to enlarge the inside diameter of the urethra and locate obstructions in the urethra, or as a treatment for urethral strictures .
Treatment of ureteric strictures varies from one patient to another depending on the level, cause and extent of stricture in addition to patient factors such as comorbidities and preferences. Treatment options include minimally invasive palliative procedures such as Nephrostomy tube insertion or ureteric stents insertion or ureteral balloon ...
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]
