Clinically they can be asymptomatic, or cause of urinary tract infections with rebellious piuri. Aim of study. Analysis of specialized literature and personal studies on the clinical cases of children with bladder diverticula. Material and methods. The work presents 3 patients with bladder diverticula, who were on treatment for a period of 2 years. Results. The age of children with congenital diverticuli was 9 months, 3 years and 5 years, of which 2 boys and a girl. Clinically all patients had urinary infection, two - stroke urination, suprapubian pain - in 1 child.
