Brief Summary:
The investigators aim to assess the effectiveness of prophylaxis of urinary tract infections in children with a probiotic containing Lactobacillus rhamnosus PL1 and Lactobacillus plantarum PM1. It is formulated a hypothesis that a 3-months course of probiotic prophylasis is more effective than placebo.

Condition or disease Intervention/treatment Phase
Prevention of Urinary Tract Infections in Children Other: Placebo control group Dietary Supplement: Probiotic experimental group Not Applicable

Detailed Description:

In previously published European and global guidelines, there has been no consensus among experts regarding the prophylaxis of recurrence urinary tract infections. Depending on the recommendation, the prevention of recurrence UTI should be used, not justified, or should be used in special cases. However, preparations that will be effective in preventing UTI and will not cause bacterial resistance are still sought.

106 patients aged 3 to 18 years with recurrence UTIs (defined as: ≥2 infections in the upper urinary tract or 1 UTI in the upper urinary tract and ≥1 in the lower urinary tract or ≥3 or more UTI in the lower urinary tract in one year) or children with ≥1 infection in the upper urinary tract and ≥1 of recurrent UTIs risk factors (congenital anomalies of the kidney and urinary tract, constipation, bladder dysfunction, myelomeningocele, sexual activity in girls) will be randomly assigned to receive a 90-days prophylaxsis arm (probiotic UroLact containing Lactobacillus Rhamnosus PL1 and Lactobacillus Plantarum PM1) or a 90-days placebo arms.

The primary outcome measure will be frequencies of recurrence of UTI during the 6 months after the intervention.

Arm Intervention/treatment
Placebo Comparator: Placebo supply for 90 days
Patients will receive placebo (in blinded sachets)
Other: Placebo control group
Placebo will be administered orally, after dissolving the sachet in lukewarm water, every evening during the meal. The placebo appearance will be similar to the probiotic.

Experimental: Probiotic supply for 90 days
Patients will receive probiotics containing Lactobacillus rhamnosus PL1 and Lactobacillus plantarum PM1 (in blinded sachets).
Dietary Supplement: Probiotic experimental group
Probiotic UroLact containing Lactobacillus rhamnosus PL1 and Lactobacillus plantarum PM1 will be administered orally, after dissolving the sachet in lukewarm water, every evening during the meal.




Primary Outcome Measures :
  1. frequencies of recurrence of UTI [ Time Frame: 6 months after intervention ]
    New onset of symptomatic UTI within the 6 months follow-up period.


Secondary Outcome Measures :
  1. frequencies of hospitalization due to UTI [ Time Frame: 6 months after intervention ]
  2. the number of days of antibiotic therapy due to UTI [ Time Frame: 6 months after intervention ]
