[Obstructive uropathia in pregnant women: results of treatment depending on the etiopatogenetic factor of development].

Actuality. The development of renal colic in pregnant women is one of the most common reasons for visiting a hospital that is not associated with obstetric pathology. Given the pharmacological and diagnostic limitations during gestation, the problem of expanding the renal cavitary system in pregnant women, as well as the choice of treatment tactics, remains a difficult clinical task. MATERIALS AND METHODS: The study group included 537 patients with obstructive uropathy with a gestation period of 5 to 36 weeks, who were hospitalized from January 2018 to January 2022 at the GBUZ GKB named after. S.S. Yudina DZM. Depending on the etiopathogenetic obstructive uropathy, the patients were divided into 3 groups: group I - 201 (37.4%) patients with gestational pyelonephritis (the presence of a systemic inflammatory response syndrome) and expansion of the renal cavitary system without confirming the diagnosis of urolithiasis; group II - 216 (40.2%) patients with renal colic (presence of pain without signs of a systemic inflammatory reaction) and enlargement of the renal cavitary system not associated with urolithiasis; group III - 120 (22.4%) pregnant women with an expansion of the cavitary system of the kidney caused by urolithiasis, both with and without signs of a systemic inflammatory reaction. Age, body mass index and previous number of pregnancies in all groups did not differ. The mean age of the patients in the three groups was 26.1 years, with a mean gestational age of 20.8 weeks. In 433 (80.6%) patients, pain was observed in the lumbar region on the right, in 83 (15.5%) - on the left, the bilateral nature of the process - in 21 (3.9%) patients. RESULTS: In group I, despite ongoing conservative therapy, 129 (64.2%) pregnant women received an internal ureteral stent. After 2-4 weeks of follow-up, the ureteral stent was removed in all patients. As a result, a short-term drainage method (up to 4 weeks) was effective in 90.1% of pregnant women, and in 13 (9.9%) patients, it was necessary to re-insert the stent, followed by a routine replacement of the drain every month. Considering the pain syndrome among patients of group II, drainage was performed in 80 (37%) pregnant women. Routine stent replacement was required in 2 (2.3%) patients. In group III, the location of the calculus in the pyelocaliceal system was in 28 (23.3%) patients, in the ureter - in 92 (76.7%) patients. Independent passage of the calculus was noted in 8 (6.7%) pregnant women, ureteroscopy without prior stenting was performed in 31 (25.8%) pregnant women with ureteral calculus. The remaining 81 (67.5%) pregnant women underwent stent placement at the first stage. When the stone was localized in the ureter, 32 (22.7%) patients underwent contact laser ureterolithotripsy and 21 (17.5%) patients underwent ureterolithoextraction. When a stone was located in the kidney, 28 (23.3%) pregnant women underwent pyelocalicolithotripsy. Achievement of the stone-free status was observed in 92.8%. CONCLUSION: Obstructive uropathy in pregnant women requires identification of the cause and a multidisciplinary approach. Long-term drainage of the urinary tract should be avoided and short-term drainage should be preferred. Surgical treatment of urolithiasis, regardless of gestational age, is an effective and safe method.

[Efficacy and safety of intermittent catheterization for acute urinary retention: a prospective comparative randomized study].

OBJECTIVES: of the study: to evaluate the effectiveness and safety of intermittent catheterization in the management of acute urinary retention and to identify factors influencing the resume normal voiding and the development of adverse events. MATERIALS AND METHODS: 129 patients admitted to urology department with acute urinary retention due to BPH were randomized into two groups. Group I had indwelling bladder catheterisation using Foly catheter. Group II was catheterized intermittently. MAIN OUTCOME MEASURES: Success rate, time to resume normal voiding, number of episodes of fever, pain, urgency and gross hematuria. Factors influencing the probability of AUR resolution and adverse events were also analyzed. RESULTS: Normal voiding was resumed in 25 (35.7%) patients in group I, and in 26 (44%) patients in group II. The probability of AUR resolution in group II was 1.5 times higher than in group I. However, this difference was not statistically significant. In group II normal voiding was restored within 1 day in 1 (3.8%) patient, in 12 (46.2%) - within 2 days, and in 13 (50%) - within 3 days. On the 7th day relapse of AUR occurred in 3 (2.3%) patients, in 2 (2,8%) patients in group I and in 1 (1.7%) patient in group II. Logistic regression analysis showed statistically significant association between the probability of developing gross hematuria and the age of the patient, as well as between possible urethrorrhagia and episodes of acute urinary retention previous to the last AUR episode. Statistically significant associations were revealed between age and the use of a-blockers at the time of the acute urinary retention episode and the probability AUR resolution. An increase in the patients age by 1 year was associated with decrease in the chances of voiding resumption by 1.07 times, and a-blockers therapy at the time of acute urinary retention increased these chances by 2.8 times. Urgency rate was statistically significantly higher in group I (30% vs. 3.4%), the chances of developing urgency were also 12 times higher in group I. CONCLUSION: Intermittent catheterization is an effective method of AUR management. The major advantages of this method are the possibility of outpatient treatment, maximum preservation of patients social and sexual activity, earlier resumption of voiding and significantly less common catheter-associated lower urinary tract symptoms.

[Combined prophylaxis of recurrent lower urinary tract infections in children and pregnant women].

The use of the combined herbal preparation Cystenium II for the prevention of recurrent lower urinary tract infections, including those in children and pregnant women, is described in the review. The etiological component of infectious and inflammatory diseases of the lower urinary tract and specific features of the interaction of microorganisms with bladder mucosa were studied. A detailed analysis of pharmacodynamic effects of Cysteniums II components is provided. The specific features of the treatment of acute cystitis in pregnant women and children older than 7 years are presented.
