PASCUAL SAMANIEGO, M. et al. Traumatic fracture of a horseshoe kidney. []. , 30, 4, pp.424-428. ISSN 0210-4806.

One-third to one-half of all patients with horseshoe kidney are asymptomatic and the condition is found incidentally. This congenital renal anomaly has shown as a predisponent condition for renal injury in blunt abdominal trauma, but often the degree of injury has a nonoperative therapy. Horseshoe kidney rupture is an exceptional pathology that require a complete diagnostic study to make an adequate management when surgical therapy is indicated. We present a fifteen year-old-male with previously unsuspected horseshoe kidney that suffered an atipic right upper-pole and mesorrenal kidney fracture after low velocity impact blunt abdominal trauma. A correct presurgical diagnose let a deferred surgical approach with rigth lower pole and horseshoe renal isthmus preservation. The trauma conditions, an excesive clinic manifestation, a clinical investigation about known congenital simultaneous anomallies and typical radiological signs, can suggest this infrequent patology. Computed tomography provide the best radiological information.
