[Dynamics of the structure of renal tuberculosis over 20 years].

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.

[Practice of urological departments during the COVID-19 pandemic]

INTRODUCTION: The pandemic of novel coronavirus infection has had a strong impact on the whole medical system, including urological departments. MATERIAL AND METHODS: We assessed the impact of restrictions due to the pandemic on the work of urological departments of private (Medical Center "Avicenna", Novosibirsk) and community (KGBUZ "City Clinical Hospital No. 11, Barnaul") hospitals;GBUZ of the Novosibirsk region "City Clinical Emergency Hospital" (GBUZ CCEH) No. 2, Novosibirsk) clinics, as well as the urogenital department of the TB Research Institute of Ministry of Health of Russia during the period from 2019 to 2020. The changes in the spectrum of surgical procedures, as well as the structure of patients' visits to a urologist were evaluated. RESULTS: In March 2020, the urogenital department of the TB Research Institute of Ministry of Health of Russia was redesigned into an observational one. Community departments worked with small restrictions or without any limitations. In KGBUZ "City Clinical Hospital No. 11, Barnaul", an increase in the number patients with bladder cancer, ureteral stones, concomitant kidney and ureteral stones by 3-27% was noted (p<0.05), as well as those with acute epididymo-orchitis, including testicular abscess. At the same time, a significant decrease in the number of patients with varicocele, pyelonephritis, chronic cystitis, chronic prostatitis, and phimosis was found. A surgical department of GBUZ CCEH from October to December 2020 was restructured to an infectious hospital;this led to a decrease in the volume of urological care and the number of procedures. The Avicenna Medical Center also established anti-epidemic measures, which made it possible not only not to reduce, but in a number of procedures to increase the volume of surgical care. CONCLUSION: Owing to anti-epidemic measures, including the patient flow distribution, an introduction of mandatory testing, an early detection of patients and carriers among employees, mask regime, the opening of an observational department, single rooms, the lack of contact between patients, short length of stay, it was possible to prevent an outbreak of coronavirus infection among patients and personnel. Both in the municipal and private urological clinics, well-organized work precluded the negative impact of the pandemic.
