Traumatic rupture of congenital pelviureteric junction obstruction.

The kidney is frequently injured in blunt abdominal trauma, accounting for 10 % of such cases and being the most commonly affected genitourinary organ in all traumas. Pelviureteric junction obstruction (PUJO) is typically a congenital and asymptomatic anatomical dilatation to the renal pelvis. This article reports on a 21-year-old male who ruptured a congenital PUJO following blunt abdominal trauma. He was managed with a retrograde ureteric stent and a staged pyeloplasty. This case highlights a rare case of urogenital injury due to blunt trauma and explores the impact of congenital anomalies can contribute to injury and lead to significant complications.
