**Question:** The recent treatment of stricture of urethra in the penile and bulbous urethra is?

**Core Concept:** Urethral stricture refers to a narrowing or scarring of the urethra, commonly caused by trauma, inflammation, or surgery. In penile and bulbous urethra, this can lead to urinary retention and other complications.

**Why the Correct Answer is Right:**

Correct Answer: **D. Penile Voiding Cystourethrogram (VCUG)**

Penile Voiding Cystourethrogram (VCUG) is the correct answer because it is a diagnostic procedure used to evaluate the lower urinary tract for structural abnormalities and evaluate the function of the bladder and urethra. In the context of urethral stricture in penile and bulbous urethra, a VCUG helps to identify the extent of the stricture, its location, and its impact on urine flow, guiding treatment decisions.

**Why Each Wrong Option is Incorrect:**

A. **Stricture urethroplasty (SU):** This is a surgical procedure used to treat urethral stricture by replacing or reconstructing the affected urethral segment. However, VCUG helps to diagnose the extent and location of the stricture, which is essential for planning the most appropriate surgical intervention.

B. **Urethrotomy:** Urethrotomy is a minimally invasive procedure used to treat urethral stricture by creating a small incision or slit in the strictured segment to relieve obstruction. Although urethrotomy is a treatment option, VCUG is essential for diagnosing the extent and location of the stricture to choose the most suitable treatment modality.

C. **Urethral dilatation:** Urethral dilatation involves gradually increasing the diameter of the urethra using a series of balloons or instruments to relieve obstruction. This option is a treatment method, but the diagnostic utility of VCUG is crucial in determining the optimal treatment approach.

D. **Balloon dilatation (BD):** Similarly to urethral dilatation, balloon dilatation involves increasing the urethral diameter using a balloon. However, VCUG is necessary to assess the extent and location of the stricture before proceeding with balloon dilatation to ensure safety and effectiveness.

**Clinical Pearls:** A well-performed VCUG can help identify the optimal treatment strategy, whether it be balloon dilatation, urethrotomy, or urethroplasty, ensuring the best possible outcome for the patient.
