A Rare Case Congenital Megalourethra in Prune Belly Syndrome

Introduction

Prune Belly Syndrome (PBS) is a rare congenital disorder affecting approximately 1 in 40,000 male births. It is characterized by a triad of symptoms: abdominal muscle deficiency, undescended testicles, and urinary tract abnormalities. In this case study, we explore an unusual presentation of PBS associated with congenital megalourethra.

Case Overview

A male neonate born at 38 weeks with a birth weight of 2500g was diagnosed with bilateral hydronephrosis. Physical examination revealed undescended testicles and an enlarged penis. Diagnostic imaging and cystourethroscopy confirmed the presence of a large anterior urethral diverticulum, leading to a diagnosis of PBS.

Key Findings:

  • Bilateral hydronephrosis with renal function impairment
  • Presence of a large diverticulum in the anterior urethra
  • Urosepsis requiring multiple hospitalizations
  • Improvement following vesicostomy and urethrostomy procedures

Clinical Significance

PBS can lead to life-threatening complications, including renal insufficiency and pulmonary hypoplasia. Early diagnosis via prenatal and postnatal ultrasound is essential.

Treatment Approaches:

  • Vesicostomy: Relieves urinary obstruction and prevents renal damage.
  • Cutaneous Urethrostomy: Enhances urinary drainage in cases of severe urethral obstruction.
  • Dorsal Slit Technique: Helps alleviate phimosis, reducing infection risks.
