ABSTRACT

Myelomeningocele is one of the congenital neurological malformations compatible with life. Spinal dysraphy is the most common cause of neurogenic bladder in children under 15 years of age. The association of myelomeningocele with neurogenic bladder increases the risk of urinary infection and renal failure.
Objective. To describe isolated microorganisms in children with sequelae of spinal cord injury and urinary tract infection.
Material and Methods. Prospective, observational study in patients with neurogenic bladder due to myelomeningocele sequelae. Variables studied: age, sex, type of microorganism isolated, number of colonies, adequate or poor genital grooming, and presence of vesicoureteral reflux. Statistical analysis was performed with frequency tables and measures of central tendency, 95% confidence interval, and correlation studies.
Results. The bacterial flora isolated in the urine cultures were: E. coli 52.3%, Proteus spp. 15.8%, Staphylococcus 11.2%, Klebsiella 10.4%, Enterococcus 7.3%, Pseudomona aeruginosa 5.4%, Enterobacter 1.5%, Morganella morganii 0.38%, Kluyvera ascorbata 0.38%, Providencia rettgeri 0.38%. The majority of patients had poor perineal grooming.
Conclusión. Pathogens of intestinal origin constitute the most common bacterial flora in urinary infections in neurogenic bladder secondary to myelominingocele.
