Abstract:
PURPOSE: Membranous glomerulopathy is a glomerular disease characterized by the presence of subepithelial immune deposits with thickening of the capillary wall of the glomerulus without inflammatory change. The pathogenesis of membranous glomerulopathy is still unknown. Its incidence is higher in males, and it is rarely found in infants and adolescents. Among the clinical manifestations proteinuria is most common, while edema and hematuria are present. According to reports from other countries, among few patients diagnosed with membranous glomerulopathy by renal biopsy, show isolated microscopic hematuria without the clinical manifestations. Little research in this area has been performed in Korea, and so we conducted retrograde studies on membranous glomerulopathy associated with isolated microscopic hematuria. MATERIALS AND METHODS: We analyzed retrogradely 109 cases of asymptomatic isolated microscopic hematuria that were diagnosed as membranous glomerulopathy by renal biopsy at Yonsei University Severance hospital from January, 1992 to July, 2001. RESULTS: In 87 of the 109 cases patients were over 15 years old while in 22 cases patients were under 15 at the time of dignosis. Only three patients showed isolated microscopic hematuria without the clinical manifestations and abnormal laboratory findings and they were all male patients under 15 years old. CONCLUSION: Few cases of the membranous glomerulopathy show only asymptomatic isolated microscopic hematuria. However, since membranous glomerulopathy can be found in patients who present with asymptomatic isolated microscopic hematuria only, if adequate indication for renal biopsy is present, we conclude that renal biopsy must be aggresively pursued in order to find the underlying disease.
