ABSTRACT

BACKGROUND:

Tuberculosis is a serious medical and social problem that does not lose its importance, despite all the advances in pharmacology and surgery. Diagnosis of urogenital tuberculosis (UGTB), as a rule, is delayed due to low index of suspicion to tuberculosis and the absence of pathognomonic symptoms.

AIM:

Determining the change in the ratio of clinical forms of renal tuberculosis from 1999 to 2020. MATERIALS AND

METHODS:

A retrospective cohort comparative non-interventional study on the spectrum of the incidence of extrapulmonary tuberculosis (EPTB) was carried out. Among all 13852 extrapulmonary tuberculosis patients which were diagnosed from 1999 to 2020, patients with renal tuberculosis were selected, and the spectrum of their clinical forms in three periods was analyzed 1st period 1999-2004 (1155 patients), second period 2005-2014 (2657 patients), and the third period 2015-2020 (671 patients). The clinical features of nephrotuberculosis in 88 patients was also estimated.

RESULTS:

Over the 20 years of the analyzed period, the number of patients with UGTB decreased by 80.6%; for the year of the COVID-19 pandemic, this figure fell by another third. In the first period, destructive complicated forms of nephrotuberculosis prevailed (922 patients - 79.8%), while the so-called "minor forms" were diagnosed in 233 patients (20.2%). In the second period, the situation was statistically significantly more favorable the proportion of destructive and complicated forms of renal tuberculosis decreased to 43.8% (1124 patients), "small forms" were diagnosed in 1443 patients (56.2%). In the third period, destructive and complicated forms of nephrotuberculosis were diagnosed in 531 patients (77.6%), and the proportion of "small forms" in comparison with the previous period decreased by half, to 22.4%. Analysis of the clinical features of renal tuberculosis, depending on the prevalence of the destruction, showed that an asymptomatic course is possible, and pain, dysuria, intoxication and renal colic are present with different frequencies, and the clinical picture of tuberculosis of the renal parenchyma differs significantly from the clinical picture of tuberculous papillitis, cavernous nephrotuberculosis and symptoms of renal tuberculosis as whole.

CONCLUSION:

Currently, there is no screening on urogenital tuberculosis at all. Patients are diagnosed by referral, with a long history, after receiving multiple courses of antibacterial treatment; mainly through the pathomorphological examination of the operating material. Thus, a sharp decrease in the proportion of UGTB patients does not mean the disappearance of tuberculosis of this localization, but only states the tragic defects in timely diagnosis and low index of suspicion of medical doctors in relation to UGTB.
