Genitourinary Tuberculosis Diagnosis and Management

Genitourinary tuberculosis (GUTB) represents a significant subset of extrapulmonary tuberculosis, affecting the kidneys, ureters, bladder and reproductive organs. The disease typically arises via haematogenous or lymphatic spread from a pulmonary focus. Clinical manifestations are diverse and often insidious, ranging from sterile pyuria, haematuria and irritative voiding symptoms to pelvic pain and infertility in women. Conventional diagnosis relies on urine microscopy, mycobacterial culture and imaging modalities such as intravenous urography, ultrasound and CT. Molecular techniques, notably nucleic acid amplification tests and cartridge-based assays, have accelerated detection and drug-resistance profiling. Management combines a standard multi-agent antitubercular regimen with surgical intervention for complications such as strictures, non-functioning kidneys or genital tract obstruction. Delayed diagnosis can result in irreversible renal damage, infertility or bladder contracture. GUTB remains a global public health concern in high-burden regions, especially where HIV coinfection and diagnostic resource limitations persist. Early recognition through integrated clinical, laboratory and imaging strategies is essential to reduce morbidity and preserve organ function.

Research from Nature Portfolio

Untargeted metabolomic profiling of follicular fluid in women with latent and active genital tuberculosis has revealed perturbations in steroid hormone biosynthesis, carbohydrate metabolism and lipid pathways that correlate with diminished ovarian reserve. These findings suggest metabolic biomarkers that could inform fertility counselling and personalised treatment strategies.

A large multicentre evaluation of a cartridge-based molecular assay on urine specimens demonstrated superior sensitivity compared with smear microscopy and culture for urinary tract tuberculosis, as well as reliable rifampicin-resistance detection. This rapid approach offers a practical alternative in resource-limited settings, enabling timely treatment initiation and antimicrobial stewardship.

Technical terms

Extrapulmonary tuberculosis: Tuberculosis infection occurring outside the lungs, often with atypical presentations and diagnostic challenges.

Polymerase chain reaction (PCR): A molecular technique that amplifies specific DNA sequences of Mycobacterium tuberculosis for rapid detection.

Xpert MTB/RIF assay: A cartridge-based nucleic acid amplification test that simultaneously detects Mycobacterium tuberculosis and rifampicin resistance.

Contrast-enhanced ultrasound (CEUS): An imaging modality using microbubble contrast agents to assess vascular patterns within lesions.

Interferon-gamma release assay: An immunological blood test measuring T-cell release of interferon-gamma in response to TB antigens, used to detect latent infection.
