Renal tuberculosis occurs due to hematogenous spread.

  • Lab reports: Sterile Pyuria
  • Best Radiological test: IVP
    • Earliest feature - feathery appearance of calyces
    • Late - Putty Kidney/Cement Kidney (Autonephrectomy)
      • Note: Autosplenectomy is seen in Sickel cell disease
    • Urinary bladder - Thimble bladder (thick wall and low capacity)
    • Ureter - Golf hole ureters
Note: Bladder calcification is uncommon in TB. Bladder calcification is seen in Schistosomiasis.
