RESUMO
Objective To explore the diagnosis of pediatric clinical hematuria disease. Methods The clinical data of one pediatric patient with IgA nephropathy combined with multiple bladder hemangioma were summarized and analyzed. Results For more than 6 years, 9-year-old female presented with repeated intermittent gross hematuria and persistent microscopic hematuria with the blood clot in urine after several respiratory tract infections. Routine urine test showed protein+++, RBC in full ifeld of vision/HP, and 0 . 54-1 . 02 g of 24 h urine protein quantitation. Early damage index of kidney is mainly based on microalbumin. The ultrasound showed no abnormal abdomen and urinary tract. Also there was no abnormality in enhanced urinary tract CT scan. Renal arteriography showed no ifstula or arteriovenous malformation. Pathological diagnosis of renal biopsy was focal proliferative IgA nephropathy. Cystoscopy examination suggested multiple hemangioma of bladder. Conclusion Bladder hemangioma is a rare condition in childhood. For children presented gross hematuria with blood clots, when the imaging ifnds no abnormalities or other diseases and the treatment of IgA nephropathy is unsatisfatry after diagnosis, the cystoscopy should be performed to exclude the possibility of bladder hemangioma.
