Renal tuberculosis happens when TB bacteria settle in the kidney. The infection moves slowly, so early clues feel like a stubborn bladder bug that keeps coming back.
Burning that never leaves is the first hint. Urination stings at the start and lingers, even after several courses of regular antibiotics.
Frequency climbs. You dash every hour, yet only a spoonful comes out each time, and the urge returns fast.
Blood shows up quietly. Urine can turn light pink, tea-brown, or contain small clots, often without any pain.
Flank ache creeps in. A dull, steady throb below the ribs can spread to the groin as scar tissue blocks the ureter.
Low-grade fever, night sweats, and weight loss tag along. You feel cold one minute, hot the next, and the scale drops without trying.
Late signs include a swollen kidney, chronic testicle ache, or pus in the urine—an alarm that the infection has destroyed tissue.
