Laparoscopic Pyelolithotomy in a Horseshoe Kidney.

The horseshoe kidney is the most frequent renal anomaly, with a prevalence of 0.25% and a male to female ratio of 2:1. In this article we aimed to report a 50-year-old man who had left kidney stones accompanied with a horseshoe kidney. In this case percutaneous nephrolithotomy was deemed to be a risky procedure due to malrotation of the pelviocalyceal system and possible interposition of bowel loops between kidney and the abdominal wall. Therefore, we preferred laparoscopic pyelolithotomy. At the end of the procedure, the patient was stone-free. We observed no complication. The patient was discharged after 72 hours. We assume that laparoscopic pyelolithotomy is a safe and effective approach for renal pelvic stone in case of horseshoe kidney. [ABSTRACT FROM AUTHOR]
