Chronic kidney disease related to renal tuberculosis: a case report

Genitourinary tuberculosis (TB) is the third most common form of extrapulmonary TB. A 34-year-old man with severe kidney function loss secondary to renal TB initially presented with urinary symptoms, including dysuria and polacyuria. The diagnosis was based on clinical history and laboratory tests; the urinalysis revealed acid-fast bacilli. The patient's condition stabilized after beginning TB-specific treatment, but the right kidney function loss persisted. Renal TB can lead to irreversible loss of renal function. As such, renal function should be considered in all patients from TB-endemic areas who present with urinary symptoms and whose urine cultures are negative for common pathogens.
