BACKGROUND AND OBJECTIVE: Hydronephrosis is defined as abnormal dilation of pyelocaliceal system. There is a controversy about the etiologies and follow up in antenatal and neonatal hydronephrosis. This study was done to determine the etiologies of hydronephrosis in neonates who were born with this disorder.
METHODS: This study was carried out on all neonates who were referred to nephrology department and clinic of Amirkola children hospital, Babol Medical University from 1998 to 2004. In whom it was diagnosed hydronephrosis before or after birth VCUG (voiding cystourethrography), IVP (Intravenous pyelography ) and/or DTPA (diethylene triamine-pentaacetic acid) were used as needed. Then all data were evaluated according to their etiologies.
FINDINGS: Of 42 neonates, 38(90%) were male and 4(10%) were female. Twenty-four (57%) and 17 (40%) patients had UPJO (ureteropelvic junction obstruction (and VUR (vesicouretral reflux), respectively. Twenty-six (62%) had been diagnosed before birth. The most common causes of admission were prenatal diagnosis (57%) and UTI (24%). Among 54 hydronephrotic kidneys unites in 42 neonates, 30 (55.5%), 23 (42.5%) and 1 had VUR, UPJO and UVJO respectively.
CONCLUSION: The most common cause of hydronephrosis in neonates was UPJO. It is needed to give more attention to male neonates who showed higher prevalence of hydronephrosis and also early prenatal sonographic diagnosis. |
