Filter by:The objective is conduct a pilot randomized controlled trial comparing robotic and open techniques for surgical correction of congenital UPJ obstruction (pyeloplasty) in pediatric patients. This study will serve as a proof of concept trial to demonstrate feasibility of recruiting pediatric patients to participate in a randomized study for surgical procedures and delineate patient-centered outcomes. Should this study prove randomization is feasible, a randomized comparative effectiveness trial with sufficient power to determine whether open or robotic-assisted pyeloplasty has superior patient-centered outcomes will be pursued.
This prospective study, Randomized Trial of Indwelling Double-J Ureteral Stent Versus Externalized Modified-Salle Stent for Pyeloplasty will consist of four steps: 1.) Enrolling subjects in the study and signing the consent form 2.) Randomly divide subjects into 2 groups, group 1 will have internal stent and group 2 will have external stent 3.) At the time of stent removal in the clinic or in the OR subjects parents/ subjects will fill a questionnaire about pain after the procedure, stent care and stent tolerance and 4) Data from the questionnaires and procedure cost will be collected and all the data will be analyzed
Prospective multicenter observational study of early infancy ureteral reimplantation for distal ureteral obstruction. The study is an observation study since the investigators will not assign specific interventions to the subjects of the study. The purpose of the study is to describe the surgical outcomes of early infancy ureteral reimplantation. Infants under 6 months of age with unilateral obstructed distal ureter, no other urologic pathologic and a normal contralateral kidney who have been recommended a ureteral reimplant by their pediatric urologist are eligible for the study. Patients that consent for the study will be prospectively followed for 1 year to record the outcomes of the surgery.
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.
