Renal Anhydramnios Fetal Therapy

AnhydramniosPotter Syndrome6 more

Early pregnancy renal anhydramnios or EPRA is a condition where a pregnant woman does not have any amniotic fluid around her fetus because of a problem with the fetus's kidneys. This condition is thought to be fatal once the fetus is born because of inadequate lung growth. The Renal Anhydramnios Fetal Therapy (RAFT) Trial offers eligible pregnant women with a diagnosis of EPRA an experimental therapy of repeated or serial "amnioinfusions" of fluid into the womb. An amnioinfusion involves placing a small needle through the pregnant woman's skin into the womb next to the fetus. Warm sterile fluid with balanced electrolytes and antibiotics is then slowly infused into amniotic space inside the womb. The aim is to help the fetus's lungs grow enough so he or she can survive after birth. These amnioinfusions will be carried out by an expert in fetal interventions at a RAFT center. There is a significant risk of early rupture of membranes and early delivery in subjects who receive amnioinfusions, and any potential trial participants will be counseled about these risks before they decide whether to join the trial. Any eligible patients who, after counseling, elect to terminate the pregnancy will not be eligible to participate in the trial. All eligible patients who choose to join the RAFT trial will be able to choose their assignment into one of two arms of the study: (1) to receive serial amnioinfusions (2) to not receive amnioinfusions but receive monitoring for the remainder of the pregnancy at the RAFT center. Thus, assignment of patients to study arm will not be random, but will be decided by the participant. Fetuses who do survive after birth will require intensive medical management for kidney failure including placement of a dialysis catheter and dialysis therapy with the eventual need for a kidney transplant. Treatment for lung disease secondary to abnormal lung development may also be required. The study will follow babies and their families until non-survival or transplant. Update: Due to recommendations from the RAFT trial Data and Safety Monitoring Board, the trial is no longer open to enrollment for pregnancies complicated by bilateral renal agenesis as of July 19, 2022. Enrollment for patients with pregnancies complicated by other causes of fetal renal failure remains open.

Decision Aid for Parents of Infants With UPJO

Ureteropelvic Junction ObstructionUreteropelvic Junction; Obstruction1 more

Ureteropelvic junction obstruction (UPJO) is the most common etiology of high-grade hydronephrosis, affecting approximately 4,000-10,000 infants annually in the U.S. The goal of surgical treatment of UPJO is to minimize the risk of kidney damage associated with obstruction, which may occur in 30-60% of infants with high-grade hydronephrosis.1-However, the benefit of early surgery compared to observation and potential later surgery to preserve kidney function has not been well-defined. Consequently, surgeons differ on whether to initially treat with surgery or observation, with surgical rates in the first year of life varying from 15-50% across surgical practices. These variations are important to understand, as the decision for early surgery is not without risk. Prior studies suggest that infants treated surgically are at higher risk for readmission and reoperation. Early surgery also raises concerns about neurodevelopmental effects of anesthetic exposure. To address this gap, the purpose of this pilot test is to develop a patient decision aid (PtDA) tool and pilot test its effect on parental understanding and engagement in the decision-making process at Children's Hospital Colorado. The proposed pilot is a necessary first step in preparation for a future multicenter hybrid effectiveness-implementation trial. This work will also be used to support future studies evaluating the impact of a PtDA on surgical variations and treatment outcomes in patients with UPJO and other complex congenital urologic anomalies.

The Efficacy and Safety of Local Anesthetic Infusion With Ropivacaine

Obstruction of Pelviureteric Junction

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.

Indwelling Double-J Ureteral Stent Versus Externalized Modified-Salle Stent for Pyeloplasty

Ureteropelvic Junction Obstruction

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

Pediatric Robotic Versus Open Pyeloplasty

Pediatric UrologyUreteropelvic Junction Obstruction

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.

Randomized Trial of NSAID vs Placebo Prior to Ureteral Stent Removal

Disorder of Urinary StentUreteral Spasm2 more

This study plans to learn more about whether ibuprofen can reduce pain after removal of a ureteral stent more than a placebo. Some patients experience pain after removal of a ureteral stent. The investigators plan to learn how often this occurs and whether it can be prevented. The investigators hypothesize that children who have a temporary, indwelling ureteral stent will experience a significantly less post-operative pain if given a non-steroidal anti-inflammatory (NSAID) prior to removal of the ureteral stent when compared to placebo. The investigators hypothesize that the incidence of severe post-stent removal pain is similar to an adult population.

Ambulatory Blood Pressure Measurement in Children With Congenital Urine Flow Obstruction

HydronephrosisMulticystic-dysplastic Kidney

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.
