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.

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 is extremely uncommon in children. But this neoplasm should be considered in the differential diagnosis of hematuria and/or abdominal mass in children. We present a case of renal cell carcinoma in an 11-year-old girl which was confirmed pathologically.

BACKGROUND: Computerized topography(CT) is the method of choice for establishing patients with abdominal and/or pelvic trauma. However, the sensitivity of CT far detecting bladder rupture has been questioned. We investigated the roles of CT as the initial evaluation of abdominal and pelvic trauma in diagnosis of bladder rupture. METHODS: We reviewed the medical records and radiographs of 53 patients with bladder rupture for last 5 year. And among them, all radiographs of 30 patients who underwent both CT and retrograde cystography were evaluated independently by two urologists who had no knowledge of the patients' final diagnosis. RESULTS: Among 30 patients, all of patients were correctly diagnosed by retrograde cystography, but the CT diagnosis was correct in only 23 patients(76.7%), who were 17 patients(85.0%) with intraperitoneal rupture and 6 patients(60%) with extraperitoneal rupture. And of the 7 patients who were negative by the CT, all showed the sign of inadequate bladder distension. CONCLUSION: We suggest that CT, if properly performed with adequate bladder filling, is as sensitive for detection of bladder injuries as conventional cystography. Especially, in trauma patients with hematuria and suspected other organ injury, CT-cystography with retrograde filing may be as accurate as conventional cystography and obviate the need for an additional plain film cystography,

PURPOSE: To evaluated the effectiveness of abdominal ultrasonography as the initial diagnostic method in blunt renal trauma. MATERIALS AND METHODS: This study was undertaken to compare computerized tomography with abdominal ultrasonography in radiographic staging of blunt renal trauma(Renal Injury scale grade I-V by Moor) except vascular injury. During 3-years period(May 1994 to March 1997), emergency computerized tomography was performed in 66 patients with blunt renal trauma, simultaneously 34 patients among 66 patient were scanned by abdominal ultrasonography. RESULTS: Gross hematuria were present 48% of renal trauma cases. The degree of hematuria showed not correlation with the severity of renal injury(p-value=0.213, by Chi-square test). In diagnostic agreement of abdominal ultrasonography compared to computerized tomography, the diagnostic agreement of minor renal injury(x=0.544, by k2 statistics) was higher than that of major renal injury(r=0.375, by k2 statistics). The overall diagnostic agreement of abdominal ultrasonography in detecting adjacent organ injury was 0.321 (k value). CONCLUSIONS: In ultrasonography imaging, we concluded that minor blunt rectal trauma is not necessary other radiologic evaluation, but major blunt renal trauma should be evaluated by computerized tomography for proper diagnosis of combined injury and diagnostic staging of renal trauma. Renal trauma associated Intraabdominal injury should undergo with ultrasonography-guided paracentesis. Based under result of our study, we suggest the use of abdominal ultrasonography as the initial diagnostic method in blunt renal trauma compatible for prompt diagnosis and treatment.

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.

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.
