[Surgery of abdominal aortic aneurysm in horseshoe kidney. Report of a case and review of the literature]. / Cirugía del aneurisma de aorta abdominal en presencia de riñón en herradura, a propósito de un caso y revisión de la literatura.

OBJECTIVE: A case of coexistent abdominal aortic aneurysm and horseshoe kidney is presented. The diagnostic difficulties and the different treatments are discussed. METHODS/RESULTS: A 55-year-old male patient with aneurysm of the abdominal aorta associated with a horseshoe kidney is described and the literature is reviewed. The diagnosis was made by CT and arteriography. Treatment was by the transperitoneal approach, division of the renal isthmus and placement of an aortoiliac dacron graft. CONCLUSION: Horseshoe kidney associated with abdominal aortic aneurysm requiring surgical management is uncommon, but when it occurs, aortic repair is significantly more difficult.

[Rectal hemorrhage as a first sign of renal cell adenocarcinoma]. / Rectorragia como primera manifestación de adenocarcinoma de células renales.

Renal cell carcinoma accounts for 85% of all renal primary tumours, the remaining 15% tumours originating either in the renal pelvis or the renal capsule. Clinical signs and symptoms of renal adenocarcinoma can be classified in four groups: specifically urological signs and symptoms, unspecific general symptoms, paraneoplastic syndromes, and metastasis-derived symptoms. The classical triad consists of haematuria, pain and palpable abdominal mass; at present this triad appears in a minority of cases, and is usually a late finding. The number of cases diagnosed from unspecific signs and symptoms is increasingly larger. Routine use of ultrasound and CAT allows a higher number of diagnosis, which frequently occur in the less advanced stages. The present paper presents a case report of renal cell adenocarcinoma, diagnosed from an infrequent early symptom such as rectal bleeding.
