**Core Concept**
Prune belly syndrome is a rare congenital anomaly characterized by the absence or underdevelopment of the abdominal muscles (muscular wall of the abdomen), often accompanied by urinary tract abnormalities, such as undescended testes in males, and sometimes other associated anomalies. The exact cause of this syndrome is unknown, but it is believed to be related to an alteration in the development of the abdominal wall during embryogenesis.

**Why the Correct Answer is Right**
The condition is named for its characteristic appearance, resembling a dried prune. The absence of abdominal muscles leads to a protuberant abdomen, with the intestines and other abdominal organs visible through the thin abdominal wall. This condition is often associated with urinary tract anomalies, including ectopic ureters, bladder diverticula, and renal agenesis. The lack of abdominal muscles can also lead to a variety of complications, including constipation, bowel obstruction, and respiratory problems.

**Why Each Wrong Option is Incorrect**
**Option A:** Prune belly syndrome is often associated with urinary tract abnormalities, including ectopic ureters, bladder diverticula, and renal agenesis. This statement is true, making option A incorrect.

**Option B:** Prune belly syndrome is characterized by the absence or underdevelopment of the abdominal muscles. This statement is true, making option B incorrect.

**Option C:** Prune belly syndrome is often associated with cardiovascular anomalies. This statement is false; while some cases may have associated anomalies, prune belly syndrome is not typically characterized by cardiovascular anomalies.

**Clinical Pearl / High-Yield Fact**
Prune belly syndrome is a rare congenital anomaly that can be associated with a variety of complications, including urinary tract anomalies, constipation, bowel obstruction, and respiratory problems. It is essential for healthcare providers to be aware of this condition to provide proper management and care.

**Correct Answer: C. Prune belly syndrome is often associated with cardiovascular anomalies.**
