A 77-year-old man with urinary tuberculosis developed post renal anuria two days after starting an anti-tuberculosis drug regimen. He had bilateral hydronephrosis, and his right kidney was radiologically diagnosed to be non-functioning. A transurethral catheter was placed in the left ureter. No improvement in the ureteral stricture was noted during the initial three weeks of treatment; however, the stricture did thereafter improve after the commencement of oral prednisolone. In cases of urinary tuberculosis, ureteral stricture can deteriorate and result in ureteral obstruction during anti-tuberculosis treatment. Pre-emptive administration of corticosteroids may be beneficial for preventing such stricture in patients with a pre-existing ureteral lesion.
