A 5-year-old boy has a history of recurrent urinary tract infections. Urine cultures have grown Escherichia coli, Proteus mirabilis, and Enterococcus. Physical examination now shows an abnormal constricted opening of the urethra on the ventral aspect of the penis, 1.5 cm from the tip of the glans penis. There also is a cryptorchid testis on the right and an inguinal hernia on the left. What term best describes the child’s penile abnormality?

**Core Concept**
The child's penile abnormality is related to a congenital anomaly of the urethra, which can be associated with other genitourinary and gastrointestinal abnormalities. This condition is often linked to an abnormal development of the urogenital and cloacal membranes during embryogenesis.

**Why the Correct Answer is Right**
The child's penile abnormality is best described as a hypospadias, which is characterized by an abnormal constricted opening of the urethra on the ventral aspect of the penis. This condition occurs due to incomplete fusion of the urogenital folds during embryonic development. In some cases, hypospadias can be associated with other genitourinary abnormalities, such as cryptorchidism (undescended testes) and inguinal hernias.

**Why Each Wrong Option is Incorrect**
**Option A:** Epispadias is a congenital anomaly where the urethral meatus is located on the dorsal aspect of the penis, which is opposite to the child's condition.

**Option B:** Phimosis is a condition where the foreskin cannot be retracted over the glans penis, but it does not involve an abnormal urethral opening.

**Option C:** Balanitis is an inflammation of the glans penis, often caused by infections or allergic reactions, but it does not describe the child's penile abnormality.

**Clinical Pearl / High-Yield Fact**
Hypospadias is a relatively common congenital anomaly, affecting approximately 1 in 200 boys. It is often associated with other genitourinary and gastrointestinal abnormalities, and early surgical correction is usually recommended to improve cosmetic and functional outcomes.

**Correct Answer:** C.

✓ Correct Answer: D. Hypospadias
