title: Giant ureteral stone in association with primary megaureter presenting as an acute abdomen.
abstract: A 20-year-old woman presented with abdominal pain of 4-h duration and of sudden onset. A plain abdominal radiograph showed a giant ureteral stone measuring 12 cm causing ureteral obstruction. Abdominal ultrasound revealed severe dilatation of the two upper thirds of the left ureter and a hydronephrotic ipsilateral kidney. Subsequent renal scan demonstrated that it was a non-functional kidney while the contralateral kidney was normal. A left nephroureterectomy was performed.
