NCT ID: NCT01711996 Withdrawn - Clinical trials for Ureteropelvic Junction Obstruction

The Correlation Between Renal Injury and Biomarkers in Pediatric Ureteropelvic Junction Obstruction Patients

Start date: August 2012
Phase:
Study type: Observational

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.

NCT ID: NCT00930046 Terminated - Clinical trials for Obstruction of Pelviureteric Junction

The Efficacy and Safety of Local Anesthetic Infusion With Ropivacaine

Start date: April 24, 2009
Phase: N/A
Study type: Interventional

The investigators propose a prospective blinded randomized control trial (RCT) to assess the efficacy and safety of a simple method of continuous infusion of a local anesthetic, ropivacaine, via a surgical wound to control pain after ureteropelvic junction (UPJ) stenosis correction in children during the first 48 hrs after surgery. The investigators hypothesize that this technique will provide greater pain relief post-operatively and reduce the need for systemic opioid use along with a reduction in associated side effects of such analgesics.

NCT ID: NCT00764543 No longer available - Hydronephrosis Clinical Trials

Ambulatory Blood Pressure Measurement in Children With Congenital Urine Flow Obstruction

Start date: n/a
Phase:
Study type: Expanded Access

PURPOSE - HYPOTHESIS: Children with unilateral congenital urine flow impairment, who require surgery, have abnormal 24-hour ambulatory blood pressure measurements. OBJECTIVES: To Measure 24-hour ambulatory blood pressure in children who have unilateral hydronephrosis or multicystic-dysplastic kidneys. To compare these blood pressure measurements between the children who require surgical correction and those who do not need surgical correction. BACKGROUND: With the introduction of ultrasound examinations of pregnant women, previously undetected abnormalities in the fetus are being detected. Dilatation of the kidney caused by congenital unilateral impairment to the urine flow either partial, presenting as unilateral hydronephrosis or complete, as seen in children with multicystic-dysplastic kidneys, id a common finding affecting approximately 1: 1,500 pregnancies (Cendron et al 1994). The majority of infants do not require surgery, with only 25% needing surgery by 18 months of age (Ransley 1991). However, i8n a few. There is an increase in renal dilatation which ultimately results in a reduction in renal function. The decision to operate is dependent on changes in renal pelvic diameter observed on serial ultrasound scans and on renal function. This process is often lengthy an requ8ires numerous scans, which can be upsetting for parents and child. M<any techniques have been used to identify, early, those patients who will require surgery. These have included: Intra-0renal pressure measurements, renal function, and calyceal diameter (Feung L 1997). To date, none have shown to be better than ultrasound (Dhillion HK 1998). Ambulatory blood pressure monitoring measures the blood pressure multiple times during a predefined period. It, therefore, more accurately reflects the continuous nature of blood pressure during both awake and sleep periods (Sorof JM 2001). Consequently, it may detect abnormalities in blood pressure that are missed on a single reading. This has been shown in the one previous study investigating ambulatory blood pressure and patient with multicystic dysplastic kidneys (Seeman T et al Eur J Pediatr 2001). In this study, 20% of the children studied had abnormal results when ambulatory blood pressure was monitored.
