Varied clinical presentations of genitourinary tuberculosis: A case series at a tertiary Philippine hospital

Abstract

Genitourinary tuberculosis (GUTB) represents a critical aspect of extra-pulmonary tuberculosis (TB). While it is the second most common form of this disease, its diverse clinical presentations pose a substantial challenge. This report, titled “Varied Clinical Presentations of Genitourinary Tuberculosis: A Case Series from a Tertiary Philippine Hospital,” aims to shed light on the intricacies of GUTB diagnosis, treatment, and its broader implications. In this case series, we present five unique clinical scenarios. Cases 1, 2, and 3, having completed TB treatment, developed spontaneous genitourinary fistulae. Case 4 was initially managed as interstitial cystitis, while Case 5 underwent diverticulectomy for a urethral diverticulum. The diagnosis of GUTB as the underlying cause in these cases, despite conventional treatment, highlights the diagnostic challenges posed by this disease. All five patients, experienced irritative voiding symptoms and recurrent urinary tract infections with limited improvement following antibiotic therapy. Imaging studies consistently revealed upper urinary tract involvement. Importantly, only one case exhibited histologic evidence of granuloma suggestive of GUTB, and microbiologic confirmation of Mycobacterium tuberculosis infection was obtained in only two cases. This underscores the need for a multidimensional diagnostic approach. The findings in this case series emphasize that GUTB diagnosis, often reliant on clinical findings supported by imaging studies and suggestive cystoscopy findings, remains critical for prognosis, even in the absence of microbiologic confirmation. Beyond the individual cases, this series offers insights into the complexity of GUTB, raising questions about the overall management and implications for TB control.
