Presentation Transcript

  1. Final week of renal!

  2. Severe hydronephrosis secondaryto congenital obstruction (arrow) to the pelviureteric junction in a female aged 2 years:

  3. Cystic dysplasia of kidneys andatresia of ureters in a female who died 11/2hours after birth. (Dysplasia here meansabnormality of tissue differentiation ormaldevelopment, not a precancerouscondition.)

  4. Bilateral hydroureter(megaloureter) and renal dysplasia in a maleaged 10 months with stenosis of the lowerends of both ureters.

  5. Polycystic disease

  6. Early adult type polycysticdisease of the kidneys in a woman aged 33who died of a ruptured berry aneurysm of theright middle cerebral artery.

  7. Acquired polycystic disease

  8. Nodular hyperplasia of theprostate,

  9. Involvement of ureter bymetastatic carcinoma in iliac lymph nodes.Early hydronephrosis.

  10. Gross hydronephrosis with veryadvanced atrophy of the renal parenchyma

  11. Poorly differentiated carcinoma(arrows) of the urinary bladder with extensiveinfiltration of all layers of the bladder wall

  12. Acute suppurativepyelonephritisand thrombophlebitis in a woman aged 67 whodied of staphylococcal septicaemia. Multiplelung abscesses were also present.

  13. Acute pyelonephritis with exudate • in tubules and interstitium

  14. Severe acute pyelonephritis andgross necrotisingpapillitis

  15. Necrotizing papillitis complicatingacute pyelonephritis

  16. Chronic pyelonephritisprobablyassociated with vesico-ureteral reflux Clubbing of the calyces(arrows) is well shown.

  17. Chronic pyelonephritis. Note large calyx(blue arrow) and cortical atrophy (red arrow).

  18. Cortical atrophy with interstitiallymphocytic infiltrate and ‘thyroidisation’ oftubules.

  19. Acute necrotising cystitis in afemale diabetic with an indwelling catheter.

  20. Severe chronic pyelonephritiswith asymmetrical renal contraction in ahypertensive uraemic woman aged 34. Noteagain the clubbing of the minor calyces(arrows).

  21. Tuberculouspyelonephritis andureteritis. Note the characteristic thickening ofthe wall of the ureter (arrows). Patients withisolated TB of the kidney present with painlesshaematuria.

  22. Chronic pyonephrosis

  23. Analgesic nephropathy

  24. Analgesic nephropathy showing corticalatrophy overlying necrotic papilla (blue arrow)and medulla (red arrow).

  25. Acute tubular necrosis in a patientwith crush injury. The swelling of the cortex isdue to dilatation of the proximal tubules.

  26. Interstitial nephritis. Allergic reaction tooral anticoagulant. Note architectural integritybut separation of elements by an inflammatorycell infiltrate.

  27. Acute renal allograft rejection. The renaltubules are separated by interstitial oedemaand inflammatory cells.

  28. Chronic rejection

  29. Myeloma kidney
