A urethral stricture is scarring in or around the urethra that narrows or blocks the passageway through which urine flows from the bladder. The scarring can occur anywhere between the bladder and the tip of the penis
It is much more common in men than women. Common in young . In addition to uncomfortable urinary symptoms such as reduced flow rate and more frequent urination, a urethral stricture can lead to complications that include urinary tract infections, prostatitis, urinary retention and kidney damage.
The retrograde urethrogram and antegrade urethrogram are imaging techniques that can help to pinpoint the length, position, and severity of the stricture. This also helps to guide the treatment course.
1. Gradually stretching the narrowed area with Teflon tubes is called dilation
2. Cutting the stricture with a laser or knife using a specially designed cystoscope (urethrotomy)
3. Surgically removing the stricture and then re-joining the ends with stiches (anastomotic urethroplasty)
4a. Graft of inner cheek mucosa taken
4b. The taken graft is used to reline the strictured part
Among the many approaches to treating strictures are gradually stretching them, a process called dilation; cutting the stricture with a laser or knife using a specially designed cystoscope (urethrotomy); and surgically removing the stricture and then reconstructing the area with grafts (anastomotic urethroplasty). The choice of treatment depends largely on the severity of the stricture. In minor cases in which the complication risk is low, doing nothing may be the best option; more moderate or severe cases are best addressed using either a minimally invasive or open surgical approach.
