| Abstract: |
Urinary tract infection (UTI) is a common problem in the new born . UTI is defined as a significant bacteriuria irrespective of site of infection in the urinary tract. Usually urinary tract infection in the neonatal period manifests after 72 hours of life. Incidence is between 0.1 to 10% in low birth weight infants. It is more frequent in male and preterm newborn infants , and may be as high as 10% in low birth weight infants the incidence of UTI is directly proportional to the presents of several risk factors for this disease . Among the risk factors, are the presence of associated infectious diseases (sepsis, bronchopneumonia septic arthritis osteomylitis, meningitis, etc.) the use of broad –spectrum antibiotics, mechanical ventilation, parenteral nutrition, intravascular catheter, and prolonged stay in the intensive care unit . renal and urinary tract malformations may be present in neonates with a urinary tract infection . in infants , the clinical presentations of UTI various from non specific sign and symptom such as poor weight gain , vomiting fever , poor feeding , and jaundice to sever illness . Between 30 to 55% of infants with UTI are reported to have urinary tract congenital abnormalities, of which vesicaouretric reflex is the most common . suckling and Moro’s reflexes are significantly weaker in group II than group I . 100%peretum neonates in group II have week suckling and poor Moro’s reflexes . There is no significant difference between full term and preterm neonates of both groups as regard suckling and Moro’s reflexes . There is a significant difference between group I( -VE cases ) and group II ( +VE cases ) as regard W.B.C count . 100% of neonates with UTI have pyuria and +VE urine culture while 35 , 7% have +VE blood culture and 28 , 6 % of them have +VE abdominal sonar findings . There is no significant difference between full term and preterm neonates with UTI as regard pyuria , urine culture , blood culture and abdominal sonar findings . 63.6 % of cases with neonatal sepsis have urinary tract infection. In our study we found the prevalence of U.T.I in neonates is 18 .7 % and in full term neonates is 20% and 16 % in preterm neonate.
