Horseshoe kidney in one of identical twin girls.
We report on a 5-month-old female twin who presented with urinary tract infection and was found to have a horseshoe kidney. Her identical twin had a normal renal anatomy. There have been only 2 other reports of a horseshoe kidney in monozygotic twins: in 1 instance both twins were affected, while in the other there was discordance.
