Congenital renal arteriovenous fistulas are rare clinicopathologic entities usually first manifested by hematuria. Renal angiography or isotopic scan establishes the diagnosis. We report a case of congenital arteriovenous fistula confirmed by renal angiography with review of literatures.

Wilms's tumor is a malignant renal parenchymal neoplasm. This tumor is most frequently discovered by palpable abdominal mass, while only total gross hematuria is not common in subjective symptom. We have experienced a four year-old girl complaining total gross hematuria and could not define preoperative diagnosis by clinical, radiological and laboratory findings. After operation, Wilms's tumor was confirmed on pathology.

Renal traumatic hematuria is a surgical emergency and a leading cause of morbidity. Embolization was performed in 5 patients with various renal vascular lesions: 2 blunt renal trauma, 1 stab woulnd, 2 intraoperative vascular lesions.The source of hemorrhage had been identified by angiography, superselective embolization was able to control hematuria in these patients

A marked low concentration of serum uric acid(0.7-1.2mg/dl) was detected in a 14-year-old boy with recurrent episodes of gross hematuria. The hypouricemia accompanied with a markedly increased urinary clearance of uric acid (32.6-56.0ml/min), which was only minimally changed after both the administration of pyrazinamide, and inhibitor of the renal tubular secretion of uric acid, and the administration of probenecid, and inhibitor of the renal tubular reabsorption of uric acid. Other renal tubular functions were normal. There were no other family members with hypouricemia. Thies is the first case report of isolated renal hypouricemia due to presecretory reabsorption defect of uric acid in the renal proximal tubule in Korea. And renal hypouricemia should be included in the diagnosis of hematuria.

Renal medullary fibromas which are arisen from the interstitial cell of the renal medulla show small, multiple nodules on autopsy Findings over age 50, but they are very rare clinically. thus several cases have been reported until 1982. When the tumors are large. their clinical presentation is characterized by loin pain, hematuria and palpable mass. The preoperative diagnosis with radiologic studies is very difficult and the confirmative diagnosis was made with pathologic finding. Nephrectomy has been the most common useful treatment and local excision can be used. We report a case of renal medullary interstitial cell fibroma in a 17-year-old girl presented with a child-head sized palpable mass on the left upper quadrant.

Renal cell carcinoma in the pediatric age group has been considered as a rare clinical disease entity but perhaps not as rare as once thought. This neoplasm should be considered in the differential diagnosis of hematuria and/or abdominal masses in children. Herein a case of pathologically confirmed pediatric renal cell carcinoma with multiple cysts in liver is presented with a brief review of literature.

Urine specimens from 60 consecutive patients with hematuria were examined with an autoanalyzer (Coulter counter model S-PLUS JR) to obtain the urinary red cell size distribution curve an mean cellular volume (MCV). Glomerular and nonglomerular red blood cells showed large differences with respect to size distribution, with the peak for glomerular cells at a smaller volume (MCV value 68.40+/-4.32fl) in comparison with the normal size distribution of nonglomerular cells (MCV value 96.78+/-5.76fl). A definite diagnosis was made which correlated with urinary red cell mean cellular volume in of 39 patients (94%) with nonglomerular hematuria and in 20 of 21 patients (95%) with glomerular hematuria. Identification of glomerular (MCV values below 80 fl) and nonglomerular hematuria (MCV values above 80 fl) can be of practical use in the clinical managements of patients. We think that this simple diagnostic work up should be adopted in the routine screening test for patient with hematuria.

IgA nephropathy can occur rarely as a complication of D-penicillamine treatment, but it is exact pathogenesis remains unclear. If a patients has gross or microscopic hematuria during D-penicillamine treatment, D-penicillamine induced IgA nephropathy should be suspected as a cause of hematuria. In those cases, renal biopsy should be taken for diagnosis and proper management. We experienced a case of IgA nephropathy confirmed by renal biopsy in a 39-years-old female patient with scleroderma during D-penicillamine therapy and report this case with a review of literature.
