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.

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.

Traumatic injuries are the leading cause of death in young people, and the renal injury is one of the major abdominal trauma. Hematuria is the most common sign of renal trauma, however the degree of hematuria and the severity of renal injury do not correlate consistently. Criteria for radiographic investigation is somewhat different according to the injury mechanism and an age. Excellent imaging modality such as computerized tomograph has made it possible to delineate not only detailed anatomic configuration for renal laceration itself but the presence of associated intra- abdominal organ injury. Renal injury may be presented as one of the multiple trauma, thus full evaluation for the overall injury severity of the patient is mandatory. Advanced supportive care techniques and awareness of the kidney's capacity for healing have facilitated non-operative management. Nowadays, operative exploration is indicated only in selected patients with major renal injury even in the patients with penetrating trauma, and high rates of renal reconstruction is possible through early vascular control. Urologic surgeon, as a major member of the trauma team, should be expertized in the surgical skills for reconstruction as well as acquiring up-to-date knowledge on diagnosis and management of renal trauma.

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.

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.
