Kidney biopsy in the Military Hospital of Morocco: Complications and histopathological findings.
Epidemiological studies on renal biopsies are necessary to establish the pattern and trends of renal diseases in a particular geographic area. In this retrospective study, we reviewed the medical records, histopathology findings and complications of renal biopsy in a region of Morocco. We studied a total of 130 native kidney biopsies taken between January 2008 and January 2012. All biopsies were examined by light microscopy and immunofluorescence microscopy. There were 86 males (66.2%) and 44 females (33.8%), with a mean patient age of 44.82 ± 17.86 (range 8-86) years. The most common indications of renal biopsy was nephritic syndrome (61.5%), followed by renal failure of unknown etiology (30.8%) and asymptomatic urinary abnormalities (5.4%). Primary glomerulonephritis (PGN) was found in 60 (46.2%) of the patients. Among the PGN cases, the most common one was membranous nephropathy (MN) (12.3%). Secondary glomerular disease (SGN) accounted for 48 (36.9%) of the cases. The most common SGN was lupus nephritis (LN) (10%). Tubulointerstitial disease [13 (10%)] and vascular disease [9 (6.9%)] were less common. The most common complications of the procedure were pain at the biopsy site in 12.3%, gross hematuria in 12.3%, perirenal hematoma in 7.7% and hematuria requiring nephrectomy in 0.8% of the patients. The most common indication for renal biopsy was nephrotic syndrome, MN was the most frequent PGN and LN was the most frequent SGN in our report.
