Abstract Background Urinary tract infection (UTI) is the most common and life-threatening bacterial infection among neonates. This study aimed to determine the prevalence, aetiology, and susceptible antimicrobial agents among neonates with UTI. Methods This was a cross-sectional analytical hospital-based study that included 152 neonates with clinical sepsis who were admitted at Dodoma regional referral hospital from January to June 2020. Bacterial growth of 1 × 103 colony forming units/mL of a single uropathogen was used to define the presence of UTI. Statistical analysis was performed using SPSS version 23.0 and multivariate analysis was used to determine the predicting factors of UTI. P <0.05 was regarded statistically significant. Results The prevalence of UTI was 18.4% (28/152). Klebsiella pneumoniae 64.3% (18/28) and Enterobacter spp. 35.7% (10/28) were the bacterial agents isolated. The bacterial isolates were 90%, and 60% sensitive to ciprofloxacin and amikacin, respectively. Low Apgar score (AOR = 12.76, 95% CI = 4.17–39.06, p<0.001), prolonged labour (AOR = 5.36, 95% CI = 1.28–22.52, p = 0.022), positive urine nitrite test (AOR = 26.67, 95% CI = 7.75–91.70, p<0.001), and positive leucocyte esterase test (AOR = 6.64, 95% CI = 1.47–29.97, p = 0.014) were potential predictors of UTI. Conclusion The prevalence of UTI confirmed by urine culture among neonates that were included in the present study indicates that this problem is common in the population where the study was conducted. Klebsiella pneumoniae and Enterobacter spp. were the uropathogens which were isolated. Ciprofloxacin, nitrofurantoin, and amikacin were sensitive to the isolated uropathogens.

The microbiome of the urinary tract plays a significant role in maintaining health through the impact on bladder homeostasis. Urobiome is of great importance in maintaining the urothelial integrity and preventing urinary tract infection (UTI), as well as promoting local immune function. Dysbiosis in this area has been linked to an increased risk of UTIs, nephrolithiasis, and dysfunction of the lower urinary tract. However, the number of studies in the pediatric population is limited, thus the characteristic of the urobiome in children, its role in a child’s health, and pediatric urologic diseases are not completely understood. This review aims to characterize the healthy urobiome in children, the role of dysbiosis in urinary tract infection, and to summarize the strategies to modification and reshape disease-prone microbiomes in pediatric patients with recurrent urinary tract infections.

Background: Multiple sclerosis patients often develop neurogenic lower urinary tract dysfunction with a potential risk of upper urinary tract damage. Diagnostic tools are urodynamics, bladder diary, uroflowmetry, and post-void residual, but recommendations for their use are controversial. Objective: We aimed to identify clinical parameters indicative of neurogenic lower urinary tract dysfunction in multiple sclerosis patients. Methods: 207 patients were prospectively assessed independent of the presence of lower urinary tract symptoms. We analyzed Expanded Disability Status Scale scores, uroflowmetry, post-void residual, rate of urinary tract infections, standardized voiding frequency, and voided volume in correlation with urodynamic findings. Results: We found a significant correlation between post-void residual (odds ratio (OR) 4.17, confidence interval (CI) 1.20–22.46), urinary tract infection rate (OR 3.91, CI 1.13–21.0), voided volume (OR 4.53, CI 1.85–11.99), increased standardized voiding frequency (OR 7.40, CI 2.15–39.66), and urodynamic findings indicative of neurogenic lower urinary tract dysfunction. Expanded Disability Status Scale shows no correlation. Those parameters (except post-void residual) are also associated with reduced bladder compliance, as potential risk for kidney damage. Conclusion: Therefore, bladder diary and urinary tract infection rate should be routinely assessed to identify patients who require urodynamics.

Introduction. In recent years, the role of fungal infection in inpatient and outpatient patients has been increasing. At the same time, there are currently no recommendations on the duration of treatment of outpatient patients with fungal urinary tract infection (UTI). Aim of the study. Optimization of methods of diagnosis and treatment of outpatient patients with fungal UTI.Materials and methods. To detect fungi in urine, the E. Koneman et al. (1997) method was improved. 56 patients with fungal UTI were examined. The efficacy of fluconazole in the treatment of fungal UTI was studied in 53 patients.Results. Candida albicans was detected in 37% of cases of fungal UTI in outpatient patients. Risk factors for fungal UTI in outpatient patients include: antibacterial therapy, infravesical obstruction, type 2 diabetes mellitus and the presence of urinary drainage. The microbiological efficacy of fluconazole therapy for 7, 10 and 14 days was 83.0%, 94.3% and 96.2%, respectively. The growth of fungi in the urine a month after treatment was absent in 86.7% of patients. In outpatient patients with fungal UTI without type 2 diabetes mellitus, the efficacy of fluconazole at a dose of 150 mg per day for 7 days was 94.9%. In patients with type 2 diabetes mellitus after 7 days of therapy, the efficacy was 50.0%.Conclusions. The most common causative agent of fungal UTI in outpatient patients is Candida albicans. To detect fungi in urine, samples should be seeded on selective media, while increasing the seeding volume to 0.1 ml and extending the incubation time to 96 hours. Fluconazole is a highly effective treatment for fungal UTI at a dose of 150 mg per day for 7 days, however, in patients with diabetes mellitus, therapy should last at least 10 days.
