[Significance of renal biopsy in patients with isolated microhematuria]

Retrospective study included 30 patients with isolated microhematuria in which renal biopsy was performed. Renal biopsy provided diagnosis in 28 (98.3%) cases, and histological finding was normal in only 2 (6.7%) patients. The most frequent finding was IgA nephritis found in 15 (50%) patients, while the other forms of glomerulonephritis were less frequent. In our patients there were no indications for steroid therapy. It was concluded that renal biopsy had great diagnostic value and that it should be preferred to invasive urologic-radiologic diagnostic procedures particularly when it is to be performed transcutaneously.
