Urinary infection is a pathology commonly encountered in pediatric age, affecting the male sex predominantly during the newborn period because after the age of one-year, female sex prevails. Symptomatology is complicated by abdominal pain which is the most common sign, especially when malformative pathology is associated, as is shown in our study. Materials and Methods We studied a group of 92 patients admitted to Children's Emergency Clinical Hospital in Gala.i during 1.01.2012-31.12.2015, aged between 2 months and 18 years who experienced urinary infections with Escherichia coli, Klebsiella spp., Proteus spp., Pseudomonas aeruginosa, Klebsiella spp, Staphylococcus spp. Results Abdominal pain in various forms of age-related manifestations was the most common symptom, so for the differential diagnosis of painful abdomen in the child, we also need to consider urinary infection. 32% of patients had recurrent infections, 62% of whom had malformative uropathy. Conclusions Abdominal pain is perhaps the most common symptom in children and its association with urinary infections is common, symptoms are often complicated and atypical (associated with vomiting, lumbar pain, diarrhea, polakiuria, dysuria, nocturnal agitation), especially to the infant and to the small child where the frequency is increased (30% of the studied group), as is evident from our study.
