, Ji Hyen Lee, Jung Won Lee Primary vesicoureteral reflux is a common genetically determined condition that is associated with varying degrees of renal scarring and represents one of the main causes of chronic kidney disease in children. Usually vesicoureteral reflux is common in urinary tract infection patient under 5 years of age. However, we report a rare case of high-grade vesicoureteral reflux and chronic kidney disease in a 10-year-old boy who was referred to the pediatric department for incidentally detected asymptomatic bacteriuria. Our case demonstrated that high grade vesicoureteral reflux patient with reduced renal function, bladder and bowel dysfunction at presentation is more likely to progress to chronic kidney disease.
Immunoglobulin A nephropathy(IgA nephropathy) Is one of the most prevalent glomerulonephritis in Korea, and nearly one third of them progress to end stage renal disease(ESR:D) over 20 to 30 years. The exact pathogenesis and therapeutic modality to inhibit theprogress of IgA nephropathy into BSRD are still uncertain in spite of lots of reports on beneficial effects of several therapeutic strategy. The present study was undertaken to know the incidence of IgA nephropathy, the mode of presentation, the characteristic pathologic findingsand the course of disease with the possible prognostic factor.
I reviewed the medical records including the pathologic reports of 37 cases of IgA nephropathy who performed renal biopsy between Jan. 1988 and Oct. 1995. The initialpresenting sypmtoms and laboratory finding, pathologic characteristic and follow-up data werealso investigated with the relationship between the initial laboratory or pathologic findings andthe deterioration of renal function.
The incidence of IgA nephropathy was 16.5%. IgA nephropathy was more prevalent in male in their 3rd decade. Gross hematuria (27%) and microscopic hematuria with significant proteinuria (24%) were the most common clinical symptoms/signs. The incidence ofneprotic syndrome among IgA nephropathy was 22%. The amount of proteinuria in total 37 subjects was 3.5±4.9g/day. Mesangial expansion (41%) and hypercellularity (41%) were themost common light microscopic finding. We couldn't find any statistically significant differencein initial blood pressure, serum creatinine and proteinuria according to the extent of mesangial IgA deposition. With the follow-up of mean duration of 22.4±0.8 months, serum creatinine increased significantly with the development of ESRD in 3 cases of subjects. These cases of ESRD all presented nephrotic syndrome initially, and did not respond to steroid therapy. The pathologic findings in 2 of them were global glomerular sclerosis and crescent formation.
IgA nephropathy is no longer the unusual and benign disease. Further prospective, controlled study is necessary to know which is the best therapeutic modality to inhibitor slow-down the progression of IgA nephropathy.

CHN contains several characteristics that include variable clinical features from progressive renal failure to Fanconi's syndrome, histologic finding of extensive interstitial fibrosis, high risk of urothelial malignancy. We are reporting a case of33 year-old female patient who was diagnosed as CHN. The patient visited our hospital with symptoms of nausea. Laboratory investigation showed metabolic acidosis with normal anion gap, hypokalemia, hypophosphatemia, proteinuria, glycosuria consistent with Fanconi's syndrome. She took Chinese herbs for slimming 4 months before. Renal biopsy showed the features of tubular cell injury with interstitial edema, accompanied by interstitial fibrosis on following biopsy, compatible with Chinese Herb Nephropathy. After 5 months, her renal function was progressed rapidly, therefore peritoneal dialysis was started. This case shows that we should consider Chinese herb as a cause of renal failure.
