Urinary Tract Pathology

Depending on the affected segment, non-tumor nephropathies can be divided into : glomerular and tubulo-interstitial nephropaties.

Primary glomerulonephritis :

  • acute diffuse proliferative glomerulonephritis (nephritic syndrome)
  • rapidly progressive (crescentic) glomerulonephritis
  • lipoid nephrosis (minimal change disease) (nephrotic syndrome)
  • membranous glomerulonephritis (membranous nephropathy) (nephrotic syndrome)
  • membranoproliferative glomerulonephritis (nephrotic syndrome)
  • focal segmental glomerulosclerosis (nephrotic syndrome)
  • IgA nephropathy (Berger's disease)
  • chronic glomerulonephritis

Secondary glomerulonephritis may appear during some systemic diseases, such as: systemic lupus erythematosus, diabetes mellitus, amyloidosis, Goodpasture's syndrome, polyarteritis nodosa, Wegener's granulomatosis, Henoch-Schonlein purpura, bacterial endocarditis.

Tubulo-intestitial nephropaties are represented by : acute tubular necrosis (nephrotoxic or ischemic), inflammatory lesions of the tubules and interstitium (acute and chronic pyelonephritis, interstitial nephritis, including drug-induced interstitial nephritis).

Renal tumors are : benign (cortical adenoma, fibroma, angiomyolipoma, oncocytoma, urothelial papilloma) and malignant (renal cell carcinoma - Grawitz tumor, nephroblastoma - Wilms' tumor, urothelial carcinoma, sarcomas).
