[Lithiasis in horseshoe kidney in children. Apropos of 6 cases].

In a 6 cases report of stones developed in horseshoe kidney in children, from 25 months old to 14 years old, diagnosis and surgical problems are analysed. Another urological malformations have to be researched mainly vesico renal reflux and pyelo ureteric junction obstruction. Diagnosis is usually made when stones give complications where septic obstruction is not rare and can be severe in children. Pre and intra-operative sonography can currently do the stone localisation. Surgical management of stones developed in horseshoe kidney seems to be done still by open surgery because new techniques as Eswl or percutaneous lithotripsy can be difficult to perform or dangerous in children on this malformation. Number of operations can often be higher than in adults, to do both treatment of the stone and associated malformation as PUJ obstruction, mainly if there are infected and septic complications.
