[Epidemiology of glomerular disease: report from a third-level center].

BACKGROUND

Renal biopsy has become one of the pillars of nephrology practice, being a very important tool in the diagnostic approach of any nephrology center, since it contributes to the identification and adequate management of glomerular diseases, which represent the third cause of chronic kidney disease in the world. In Mexico there are few reports on the epidemiology of glomerular diseases; therefore, it is important to carry out this type of study.

OBJECTIVE

To identify which are the main glomerulopathies reported in our center, Determine the most prevalent glomerular syndrome according to the reported glomerulopathy, and identify the main complications after percutaneous renal biopsy.

MATERIAL AND

METHODS

A retrolective cross-sectional study which included patients who underwent percutaneous biopsy of the native kidney from August 2020 to August 2022; we obtained information from the service's database.

RESULTS

89 biopsy reports were analyzed, out of which 66.29% corresponded to the female gender and 32.70% to the male gender. The average age was 37.6 ± 12.86 years. The most frequent primary glomerulopathy was focal segmental glomerulosclerosis (FSG) in 22.5%, followed by membranous nephropathy in 7.9%. The most frequent secondary glomerulopathy was lupus nephropathy in 42.7%. Nephrotic syndrome occurred in 43.85% of cases. 89% of the patients did not present post-biopsy complications.

CONCLUSIONS

FSG is the most common primary glomerulopathy. Nephrotic syndrome was the main indication for renal biopsy. The vast majority of patients did not present complications, so we can consider it to be a safe and above all useful procedure for the diagnosis of glomerular diseases.
