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.

Ureteroscopy is the newer procedure for the treatment and diagnosis in the ureteral lesion.

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

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 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.

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.

Fibroepithelial polyp of the ureter is a extremely rare benign tumor which is mesodermal origin. It should be suspected preoperatively in cases with a long history of loin pain or hematuria, or both, in a younger patient with the radiologic finding of long ureteric filling defect. Unfortunately. in the majority of cases reviewed. the diagnosis was not made preoperatively but the diagnostic confirmation was made intraoperatively or postoperatively. Herein, we report a case of fibroepithelial polyp or the ureter which was diagnosed preoperatively with ureteroscope. The management was local segmental excision and end-to-end anastomosis of the ureter.
