NCT01330511 | Completed

• 1 other identifier: 10020402
• Study Type: observational
• Target: 76
• Locations: 1 country
• Sites: 1

Brief Summary

Patients with congenital hydronephrosis will be identified by inpatient consultations performed by Dr. Assadi for congenital hydronephrosis and by outpatient problem lists with congenital hydronephrosis of Dr. Assadi's existing patients. Given standard evaluation will be evaluated to determine if based on initial ultrasound classification an algorithm can be developed to target evaluation studies for the initial evaluation. With a goal of targeting the few children that have need of additional intervention and minimizing the studies performed on children who will spontaneously resolve.

Conditions

Congenital Hydronephrosis

Keywords

Newborn infant; Congenital hydronephrosis; Postnatal imaging evaluation; Diagnostic algorithm

Outcome Measures

Primary Outcomes (1)

• surgical intervention required

  Primary outcome will be progressive renal function decline and progression to referral to a pediatric urologist for pyeloplasty.

  Follow for minimum 1 year, approximately 2 years goal
