Active clinical trials for "Hydronephrosis"

Urinary Neutrophil gelatinase associated lipocalin (NGAL) has been recently reported to be related with the degree of hydronephrosis in pediatric ureteropelvic junction obstruction (UPJO) patients. We are trying to analyze whether it is related with the grade of renal injury in UPJO patients.

In this retrospective study the investigators will enroll newborns that were born between 01.01.2010 and 31.12.2012 in Hillel Yaffe Medical Center with the prenatal diagnosis of Pyelectasis according to prenatal sonographic screening test. These babies underwent renal sonography at the age of 2-5 days according to the protocol and were invited to an additional renal sonographic screening test at the age of 1 month. The investigators will compare the results of the 2 examinations and the investigators will try to reach conclusions whether there is correspondence between the severity of the pyelectasis in the first and second sonographic tests and the outcome of these newborn babies

Hydronephrosis describes a condition of urine-filled dilation of the collecting system. Normally, urine flows through the urinary tract with minimal or low pressure. If the build-up of excess fluid in the urinary collecting system continues, there will be an increase in pressure and atrophy of renal cortex. If hydronephrosis is left untreated for a long time, renal damage with permanent loss of function occurs
