Kidney Biopsy: An Experience from Tertiary Hospital

Abstract

Introduction: Kidney Biopsy is an important diagnostic tool in Nephrology. It is useful in Nephrology in terms of diagnosis, prognosis and management. There is little information on renal biopsy data from central Nepal. We describe our center`s experience in kidney biopsy in term of histological patterns, complications and outcomes. Methods: We prospectively analyzed the biopsies data of patients over a period of one and half year. All kinds of kidney disease patients were included for kidney biopsy, irrespective of their clinical syndromes and underlying diagnosis. Results: A total of 75 biopsies were analyzed. Majority of them were females; 56% (n=42). Most of the biopsies; 84% (n=63) were from younger subjects ≤ 45 years and majority of them fell in the age group 11-20 years. Most common clinical renal syndrome to undergo biopsy was Sub Nephrotic range Proteinuria in 53.3% (n=40). Among comorbid conditions, 53.3% (n=40) had Hypertension. The most common histological pattern seen was Mesangial proliferative Glomerulonephritis (MesPGN) seen in 24% (n=18). Among complications associated with the procedure, macroscopic hematuria was seen in 6.7% (n=5) cases and clinically significant perinephric hematoma causing pain was seen in 5.3% (n=4). There was no mortality associated with biopsy procedure. Conclusions: Sub Nephrotic range Proteinuria was the commonest clinical renal Syndrome observed. In terms of renal histology, Mesangial Proliferative Glomerulonephritis (MesPGN) was the commonest histological pattern observed. Kidney biopsy is a safe procedure without any significant adverse events. Keywords: Kidney biopsy, sub nephrotic range proteinuria, mesangial proliferative glomerulonephritis
