Urogenital Tuberculosis: A Narrative Review and recommendations for diagnosis and treatment.

Abstract

Purpose: to review the more relevant aspects of urogenital tuberculosis (UGT) and make recommendations about the diagnosis and treatment.

Materials and methods: a literature review was conducted in the Pubmed, Embase and Scielo databases in search of studies on UGT in the past 60 years. A narrative review was performed concerning six topics of UGT diagnosis and treatment. Recommendations were made supported on degrees of evidence according to the modified GRADE system.

Results: UGT suspicion occurs in persistent hematuria or pollakiuria with sterile pyuria; stenosis and/or thickening of the urinary tract; or chronic prostatitis or epididymitis. Urinary bacteriological tests have low sensitivity, and a negative test does not rule out UGT diagnosis. In ureteral stenosis, a double-J catheter or nephrostomy should be used early (up to 1 month) during pharmacological treatment and in single less than 2 cm stenosis endoscopic treatment may be attempted. Bladder augmentation with ileum, sigmoid or ileocecal segments should be performed when the contracted bladder capacity is less than 100 mL. Spontaneous voiding occurs in most patients after bladder augmentation.

Conclusion: The diagnosis of UGT depends on a high degree of suspicion based on non-specific symptoms and radiological findings. Urinary bacteriological tests have low sensitivity, but even in the absence of diagnostic confirmation, treatment can be carried out through a combination of drugs for a period of six months. In the presence of ureteral stenosis or contracted bladder, complex but well stablished reconstruction procedures are necessary.
