title: [Renal needle biopsy in the Department of Nephrology in Fès: indications and results in 522 cases].
abstract: The contribution of renal needle biopsy (RNB) to make a diagnosis, a treatment selection and a prognostic evaluation of nephropathies is significant. No Moroccan study has evaluated the practice and the contribution of RNB. Our aim was to study RNB indications, to determine the frequency of kidney diseases identified by RNB in our region and make a comparison between clinical and biological data and histological diagnosis. This is a retrospective study conducted between January 2009 and December 2012. We included all patients in the Department of Nephrology, CHU Hassan II, Fez, who underwent biopsy of native kidneys. 522 RNB were performed. We excluded 8 biopsies due to lack of informations and 514 were retained. The average age of the patients at the time of RNB was 39±17 years (3-82 years). Sex ratio was 0.9. Nephrotic syndrome was the most common clinical diagnosis to all ages (58.2%). Glomerular nephropathies represent 94,2% of diagnosed renal diseases, their distribution varies according to patients' age. RNB confirmed the first clinically suspected diagnosis in 40.65% of cases, whereas it revealed an unexpected diagnosis in 22.5% of them. Syndromic diagnosis can orient the clinician toward the most probable kidney disease and guide any emergency treatment while awaiting RNB results. But it can never replace RNB which remains the gold standard.
