Urethral stricture denotes the narrowing of the urethra because of formation of scar tissue. These strictures obstruct the free flow of urine through the urethra. The urethra is classified into prostatic and anterior urethra. Urethral strictures are classified into anterior urethral strictures and posterior urethral stricture. Anterior urethral strictures are more frequent, whereas posterior urethral strictures are linked with pelvic fractures.
Urethral strictures are caused due to infections such as gonococcalurethritis; radiation to the pelvic region in patients with prostate cancer; inflammation such as lichen sclerosus, which affects the penile skin; trauma due to injury to the urethra, which may lead to rupturing; use of cystoscope and urinary catheter for numerous procedures; and after surgical procedures such as radical prostatectomy and transurethral resection of the prostate. The symptoms of urethral strictures include difficulty in passage of urine with poor urinary systems, continued dripping of urine due to incomplete draining of the urinary bladder, high frequency of urination, and bloated bladder. Risk factors linked with urethral strictures are urinary tract infections, abscesses, thickening of the bladder wall, hydronephrosis, stone formation in the urinary bladder, and in extreme cases urethral strictures may lead to kidney failure. Diagnosis of urethral stricture is based on the patient’s medical history and confirmatory tests such as urine test, ascending urethrography, ultrasound, uroflow study, and urethroscopy or cystoscopy.
The treatment for urethral strictures consist of direct visualization internal urethrotomy(DVIU), urethral dilatation, and urethroplasty surgery. The post-operative care for urethral strictures comprises removal of drain tubes after 24 to 48 hours. Multiple visits to the health care provider are planned at intervals of three months to six months and every year for a minimum of five years during. Uroflow study is carried out during the various follow ups.
