Mycobacterium tuberculosis(MTB)-related secondary immunoglobulin A (IgA) nephropathy is reported in a 72-year-old male patient. The patient was diagnosed to have MTB infection of the kidney and genitourinary tract which was diagnosed by the demonstration of the organism by GeneXpert Ultra and culture. Concurrent kidney biopsy showed IgA nephropathy. The patient responded to urethral double-J stenting and four-drug antituberculous therapy with improvement of kidney function and resolution of MTB. IgA nephropathy can present as primary glomerulonephritis or secondary to MTB infection.
