title: Renal tuberculosis and iliopsoas abscess: Two case reports.
abstract: The urinary system is the second most commonly affected site of extrapulmonary tuberculosis (TB). Due to the diverse and atypical clinical manifestations of urinary TB, the disease is easy to misdiagnose. In the present study, two cases of renal TB are reported, which had completely different clinical manifestations. The first case is a female who presented with loin pain and fever. Purified protein derivative (PPD) and TB antibody tests were negative and computed tomography (CT) scans showed a low density focus in the right kidney with an iliopsoas abscess. The typical CT findings indicated renal tuberculosis. Anti-TB drugs were effective proved the diagnosis. The second case is a male who presented with intermittent gross hematuria. Acid-fast bacilli in urine and TB antibody tests were positive. CT scans revealed a low density focus in the unilateral kidney with a slight expansion of the pelvis, calices and ureter. The patients were treated with the anti-TB drugs and the clinical manifestations disappeared. The diagnosis of urinary TB is challenging in certain cases; when there is no response to the usual antibiotics in patients with fever or gross hematuria, TB should be suspected. CT is the mainstay for investigating possible urinary TB.
