Optical urethroplasty is done in ?
**Core Concept**
Optical urethroplasty is a surgical technique used to repair urethral strictures, which are narrowings of the urethra that can cause urinary obstruction and other complications. The procedure involves opening up the urethra to visualize and repair the stricture, hence the term "optical" urethroplasty.
**Why the Correct Answer is Right**
The correct answer is **B. Urethral strictures**. Optical urethroplasty is specifically indicated for urethral strictures that are not amenable to other treatments, such as endoscopic dilation or incision. The procedure involves making a small incision in the urethra and using an endoscope to visualize the stricture. The surgeon can then use various techniques, such as excising the stricture and repairing the urethra with a graft, to restore normal urethral function.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because optical urethroplasty is not typically used to treat urethral tumors or other types of urethral pathology.
**Option C:** This option is incorrect because optical urethroplasty is not a minimally invasive procedure and typically requires a more extensive surgical approach.
**Clinical Pearl / High-Yield Fact**
One important thing to remember is that optical urethroplasty is often reserved for patients with complex or recurrent urethral strictures that have not responded to other treatments.
**Correct Answer:** B. Urethral strictures
