Obstructive uropathies present changes in anatomy and function of urinary tract. They are usually discovered during the examination of urinary tract infection.
Aim of study To present the most frequent causes in the most frequent types of obstructive uropathyes in neonates.
Materials and Methods In our study, 38 neonates were included and they were diagnosed in the Pediatric Clinic during the period of time 2010/2011. They were diagnosed by bacteriological examination of urine, renal ultrasonography, and radiologic examination such as voiding cystourethrogram and excretory urogram.
Results of study From 38 neonates, 52.24% were males and 47.76% were females. Vesicoureteral refluks (VUR) is the most common obstructive uropathy in this age and is present in 75% of all cases. Megaureter is present in 25% of cases and posterior urethral valves are present in 12.5% of cases. Results of bacteriological examination show that VUR is connected with Klebsiella pneumonie in 65.1% of cases, while with Ecoli in 34% of the cases. At megaureter the most frequent cause of infection was Klebsiella pneumonie in 68.1%, while E.coli in 38.2% of cases. At posterior urethral valves, E coli was the most frequent cause of infection in 56.3% of the cases. Klebsiella pn. was present in 16.7% of the cases and Proteus spp. was isolated in 25% of cases.
Conclusion According to the results of the study, it can be concluded that the most frequent cause of urinary tract infection at obstructive uropathies is Klebsiella pneumonie.
