Abstract

Horseshoe kidney (HSK) is a rare congenital malformation of the kidney with reported prevalence between 1 in 600 and 1 in 400. A typical HSK has two lower poles fused across the midline in front of the abdominal aorta just below the origin of the inferior mesenteric artery. Very rarely, the upper poles may fuse resulting in a reverse HSK. It is more common in males than in females, but no definite racial or genetic predilection has been established. The HSK is frequently associated with other congenital anomalies, the most common being vascular anomalies. This report describes HSK in a 73-year-old male cadaver, with triple renal arteries and aberrant right testicular artery originating from the ipsilateral renal artery and bilateral extra-renal calyces. Although rare in occurrence, a surgeon must bear in mind that such a combination of anomalies may pose technical difficulties during open or laparoscopic abdominal surgeries.

Resumo

O rim em ferradura é uma malformação congênita rara, com uma prevalência relatada entre 1 em 600 a 1 em 400 casos. Um rim em ferradura típico apresenta dois polos inferiores fundidos ao longo da linha média, à frente da aorta abdominal, logo abaixo da origem da artéria mesentérica inferior. Muito raramente, os polos superiores podem se fundir, resultando em um rim em ferradura reverso. Essa malformação é mais comum em homens do que em mulheres, embora não tenha sido estabelecida predileção racial ou genética definida. O rim em ferradura frequentemente se associa a outras anomalias congênitas, sendo as mais comuns as anomalias vasculares. Este relato descreve um caso de rim em ferradura em um cadáver masculino de 73 anos, com artérias renais triplas, artéria testicular direita aberrante originada da artéria renal ipsilateral e cálices extrarrenais bilaterais. Embora seja uma ocorrência rara, o cirurgião deve estar ciente de que essa combinação de anomalias pode representar dificuldades técnicas durante cirurgias abdominais abertas ou laparoscópicas.
