RESUMO
Renocolic fistula is rare. Renal cyst infection is a serious complication in patients with autosomal dominant polycystic kidney disease (ADPKD). We present a case of refractory renal cyst infection due to renocolic fistula in a patient with ADPKD. A 65-year-old man with ADPKD on hemodialysis visited our hospital with complaints of fever and left abdominal pain. We diagnosed renal cyst infection with abdominal computed tomography scans. After hospitalization, gas shadow was observed in the left renal cyst. Percutaneous puncture of the cyst was performed. Because contrast medium into the left renal cyst through nephrostomy was flowing into the descending colon, renocolic fistula was diagnosed. The patient underwent nephrectomy combined with partial descending colonic resection and splenectomy, but he died. Renocolic fistula is probably hidden in some refractory renal cyst infection cases. This case report aims to create awareness of renocolic fistula, so that early diagnosis and intervention can salvage such patients.
RESUMO
CKD is a common disease that is estimated to develop one in eight persons in Japan. The CKD itself is highly risk factor on the cardiac/vascular mortality. In addition,a new concept has been proposed "CKD-MBD". CKD-MBD is composed of a combination of abnormal mineral metabolism, abnormal bone, and extra skeletal calcification with cardiovascular high mortality. Treatment for CKD-MBD is a wide-ranging. We aim to decline cardiovascular event, fracture, and mortality rate of patients with CKD. The main therapeutic target for CKD-MBD becomes the phosphate control. Today, we can use of the VRDA, Calcimimetics and muti-phosphate binders as a lot of pharmacological intervention.
