7. Diagnosis Renal Biopsy:
Probable chronic glomerulonephritis with extensive glomerulosclerosis and parenchymal scarring.
Polymorph aggregates in collecting ducts suggesting ascending bacterial infection.

8. Comment
Despite evidence of ascending bacterial infection, the most likely cause of disease is chronic GN. The changes seen in the 2 non-sclerotic glomeruli support the idea of primary glomerular disease.
However, various glomerular changes would be expected with compensatory hypertrophy so one cannot completely exclude the possibility of primary tubulointerstitital disease.
