Introduction:

Renal biopsy is one of the essential tests for the characterization of chronic kidney disease (CKD).

Objective:

To determine the most frequent primary and secondary glomerulonephritis, complications of renal biopsy, and the number of patients on hemodialysis when undergoing renal biopsy.

Methods:

Observational, descriptive, case series, retrospective, and cross-sectional study carried out at the E. Rebagliati Martins-Perú. The medical records of patients older than 15 years of age who underwent kidney biopsy between 2008-2016 were reviewed. The data were processed using Stata 16.1

Results:

2278 medical records were used. They corresponded to 1234 women and 1044 men. The most frequent primary and secondary glomerulonephritis were focal and segmental glomerulosclerosis (FSGS) 683 (29.98%) and systemic lupus erythematosus (SLE) 434 (19.04%) respectively. A total of 1644 biopsied patients were analyzed 36 (2.19%), 241 (14.66%) had major and minor complications respectively. Major complications were more frequent when the procedure was performed by radiology with ultrasound guidance compared to that performed by the nephrologist without ultrasound guidance (p = 0.03694). From a total of 1324 patients, 329 underwent kidney biopsy while on hemodialysis, 43 (13.07%) managed to get out of this therapy, and 144 (51.99%) had major or minor complications.

Conclusion:

FSGS and SLE were the most frequent primary and secondary glomerulonephritis, respectively. In 1644 patients the major and minor complications were 36 (2.19%) and 241 (14.66%) respectively. In 1,324 patients, 329 (24.8%) were biopsied while on hemodialysis, and 144 (51.99%) of them had major or minor complications.
