Filter by:Diagnosis and follow up of hydronephrosis is actually based on repeat ultrasonography and scintigraphy wich is a binding exam for children. We wanted to evaluate the use of ultrasonography sensibilized by an oral hydration and to determine its efficiency to detect which hydronephrosis need a surgery or not.
Etomidate is an unique drug used for induction of general anesthesia and sedation. Adrenal cortical inhibition by etomidate has received much attention. However wether the circadian rhythm and pulse secretion pattern of cortisol in children are the same as that in adults is not known. Moreover, the effect of etomidate on circadian rhythm changes and clinical outcomes has never been carefully studied in children undergoing surgery. Our hypothesis is that etomidate can relieve the changes of circadian rhythm of salivary cortisol in children for 24-48 hours，and this does not make clinical outcomes worse postoperatively.
The aim of this study is to identify the root cause for the significant discolouration of Boston Scientific Percuflex based stents.
The purpose of this study is to assess the clinical significance of supranormal differential renal function (DRF) in the recovery of unilateral hydronephrosis (HN) after surgery, pediatric patients who underwent pyeloplasty for ureteropelvic junction obstruction (UPJO) who showed supranormal DRF (> 55%) in the DTPA renography will be analyzed.
Pediatric upper urinary tract dilatation (hydronephrosis) is relatively common and may be either obstructive or nonobstructive. While the upper urinary tract is commonly evaluated by ultrasound, this imaging technique often fails to distinguish obstructed from nonobstructed systems. ARFI SVI is a new ultrasound technology that can be used to determine stiffness by measuring a tissue's shear wave velocity, may show alterations in parenchymal shear wave velocity in kidneys that show obstruction on DRS (Diuretic renal scintigraphy)which serves as the reference standard.
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
The purpose of the study is to investigate the impact of ureteral stents on the functioning of ureteral peristalsis (normal contractions in the ureteral organ muscle).
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.
Kidney stones cause severe pain. Patients with a stone lodged in the ureter (the tube that drains the bladder), require urgent treatment with a stent to relieve the blockage. This tube, or ureteral stent, gives the patient relief until they can have their stone treated. This study is to evaluate a new type of ureteral stent to relieve pain from kidney stones. This stent is designed to drain the kidney and unlike other ureteral stents, is also designed to widen the ureter to help the stone pass on its own.
The purpose of this study is to compare a rapid noncontrast MRI protocol not requiring sedation to ultrasound in the assessment of hydronephrosis.
