Early diagnosis and interventional therapy of acute renal infarction / 中华泌尿外科杂志

ABSTRACT

Objective To discuss the early diagnosis and interventional therapy of acute renal infarction.Methods The diagnosis and therapy of 5 cases of acute renal infarction were retrospectively analyzed.There were 4 male and 1 female patients,aged 38-68 years.The symptoms were severe back pain or upper abdominal pain,with or without nausea and vomiting and the time to hospital was 1 to 16 h.Four cases had rheumatic heart disease and 4 cases had artrial fibrillation history.The lab assay results: WBC 8.9-15.8 × 109/L,urine RBC-to + + +,albumin + to + + +,serum creatinin 66-216 μmol/L,serum LDH 350-920 U/L.The doppler ultrasound and CT scan showed large infarction in 3 cases and focal infarction in 2 cases.Percutaneous arteriography,thrombolytic therapy and thrombosuction via catheter were applied promptly.Results The 5 cases were diagnosed and treated timely and effectively.The emboli were cleared.Four patients were followed up for 3-12 months.The creatinin recovered to 53-122 μmol/L,and the blood perfusion of the infarction lesion was satisfactory.Conclusions Early diagnosis and interventional therapy is important for achieving satisfactory recovery of the acute renal infarction.Three dimensional CT angiography could conduce to early diagnosis and follow-up.Thrombosuction via catheter plus thrombolytic therapy is efficient for greater embolus.
