Rare case: Ureteropelvic junction complication presenting with bilateral labial abscesses and urosepsis requiring nephrectomy

Ureteropelvic junction obstruction (UPJO) is the most common cause of urinary tract obstruction in pediatric patients. Debates in management include ureteral stent versus nephrostomy tube placement prior to surgical correction if intervention is warranted. We present a female patient with left UPJO, diagnosed at 15-years-old, treated with ureteral stent placement. Stent removal two years later resulted in extensive complications, including retroperitoneal infection, labial abscesses, and nephrectomy. Management of UPJO in the pediatric population prior to surgical correction is not well-standardized. The severity of complications following the removal of the two-year-old stent suggests caution for placing ureteral stents without proper follow-up. •Perinephric Abscess•Ureteropelvic Junction Obstruction•UPJO treatment•Prolonged Indwelling Ureteric Stent Complications•Nephrectomy
