INTRODUCTION: It is common experience to all urologists to manage many @entity1 admitted at night from the casualty ward with a diagnosis of "therapy-resistant renal colic". However not all the @entity1 with @entity812 really suffer for renal colic, although @entity158 somatic irradiation refers to the same areas. CASE REPORT: A seventy years old male @entity1 was admitted from the casualty ward for left renal colic. Laboratory tests showed normal @entity1011 , mild reduction of albuminemia, elevated @entity1674 and @entity165 at the upper limit of normal. The @entity158 had risen sharply a few hours before. For some years the @entity1 suffered @entity2183 , but he never made an urologic consultation. Ultrasonography performed in the casualty ward demonstrated normal findings with no @entity3041 but the presence of left perirenal extravasation with "casting-like" aspect and extending to the pelvis. Contrast-enhanced computed tomography (CT) revealed the presence of @entity715 and @entity1151 . The left kidney, apart from increased volume and reduced parenchymal impregnation, showed no neoplastic nodule. The case presented as unusual according to the opinion of consulted nephrologists, vascular surgeons and urologists (also from others hospitals and universities). After informed consent of the @entity1 (stressing seriousness and singularity of his condition), we decided to treat him as a @entity1150 . We administered an heparin bolus (80UI/kg), followed by the infusion of heparin (18UI/kg/h) using a peristaltic pump for 14 days. RESULTS: CT performed after 14 days of treatment showed the full resolution of renal vein thrombus and of @entity1151 . Thereafter a @entity1985 was diagnosed and the @entity1 was took in care by the nephrologist. @entity1985 preceded the hospital admission of the @entity1 and was the etiological cause of @entity715 . DISCUSSION: The well known causes of acute @entity812 reported in textbooks include renal and perirenal inflammatory processes, renal cell or transitional cell cancers of the kidney or of the urinary tract, obstruction of the urinary tract by stones or stenosis, @entity3041 of different etiology whereas vascular causes are not often mentioned. CONCLUSIONS: After the diagnosis of @entity715 , the more probable associated urological is a @entity1358 . Excluding @entity703 other possible causes of @entity715 are medical conditions such as @entity2783 , @entity1582 , @entity1985 , @entity2268 .
