The frequency of glomerulonephritis (GN) may vary depending on developmental areas and geographic location. The characteristics of 152 patients with nephrotic syndrome (NS) admitted to Dicle University School of Medicine between 2001 and 2007 were retrospectively analyzed. Of 152 patients 76 (50%) was female and 76 (50%) was male. The mean age of patients was 36.30 ± 16.5 years. 106 patients (69.7%) had a histologic diagnosis. The frequencies of primary glomerulonephritis were as followed: membranous GN (MGN) 28%, membranoproliferative GN (MPGN) 24% and focal segmental glomerulosclerosis (FSGS) 22.7%. In conclusion MGN was the most common primer GN type in biopsies performed with an NS indication in our region. In our study, MPGN, a decreasing GN type in developed countries, is still common in our region but has a trend to decrease.
