NCT ID: NCT06382233 Recruiting - Clinical trials for Chronic Kidney Diseases

The PRO-FUTURE Project

PRO-FUTURE
Start date: January 30, 2024
Phase:
Study type: Observational

The goal of this observational study is to learn about specific biomarkers of unilateral ureteropelvic junction obstruction (UPJO) in children undergoing surgical intervention for unilateral UPJO compared with controls. The main question it aims to answer are: - Are Urinary single-cell and extracellular vesicles (EVs) screening useful to stage the intrarenal injury and repair processes in UPJO babies? - Do babies with unilateral UPJO have a whole blood gene expression profiling (WBGEP) allowing an accurate unilateral UPJO diagnosis?

Long-term Outcome of Retroperitoneoscopic One-trocar-assisted Pyeloplasty: A Single-center and Single-surgeon Experience

Start date: May 2011
Phase:
Study type: Observational

Open surgical dismembered pyeloplasty has traditionally been the preferred method for treating ureteropelvic junction obstruction (UPJO), with a success rate exceeding 94%. However, it is associated with drawbacks such as increased postoperative pain, extended hospital stays, and visible scarring. Minimally invasive alternatives, including laparoscopic pyeloplasty (LP) and robot-assisted laparoscopic pyeloplasty (RALP), have gained popularity since their introduction in 1993, offering comparable success rates to open surgery while providing cosmetic benefits and shorter hospital stays. Nevertheless, these techniques present challenges in pediatric patients, including limited working space, technical complexities, and prolonged operative times. The retroperitoneoscopic one-trocar-assisted pyeloplasty (OTAP) method, introduced in 2007, combines the advantages of minimally invasive surgery with the success rates of standard dismembered pyeloplasty. Despite favorable outcomes reported by several researchers, comprehensive studies regarding long-term follow-up and clinical outcomes are lacking. This study aims to evaluate the long-term outcomes of OTAP, addressing this gap in the medical literature.

NCT ID: NCT05900375 Recruiting - Clinical trials for Ureteropelvic Junction Obstruction

Decision Aid for Parents of Infants With UPJO

Start date: January 21, 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05895422 Recruiting - Clinical trials for Ureteropelvic Junction Obstruction

Functional Outcome After Minimally Invasive Pyeloplasty for Adult Patients With UPJO

Start date: June 1, 2023
Phase: Phase 3
Study type: Interventional

an intervention study on adult patients with uretero-pelvic junction obstruction (UPJO) due to crossing vessels would be managed either through classic dismembered pyeloplasty or vascular hitch.

NCT ID: NCT04884945 Terminated - Clinical trials for Ureteropelvic Junction Obstruction

Pediatric Robotic Versus Open Pyeloplasty

Start date: October 24, 2017
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03101891 Recruiting - Clinical trials for Lower Urinary Tract Obstructive Syndrome

Renal Anhydramnios Fetal Therapy

RAFT
Start date: December 21, 2018
Phase: Phase 1
Study type: Interventional

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.

Start date: January 2016
Phase: N/A
Study type: Interventional

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

NCT ID: NCT02276924 Completed - Nephrolithiasis Clinical Trials

Diagnostic Relevance of Laser Confocal Microscopy for the Screening of Upper Urinary Tract Tumors

UROVISIO
Start date: October 2013
Phase: N/A
Study type: Interventional

Upper Urinary Tract Tumors have an incidence of 1 to 2 cases for 100 000 persons per year. The standard treatment for these tumors is the ablation of the kidney, ureter and a part of the bladder surrounding the ureteral orifice. The development of new diagnosis and treatment techniques through natural routes opens the possibility to use conservative treatments. The investigators hypothesis is that during a reno-ureteroscopy, laser confocal microscopy will allow the discrimination between normal and pathologic urothelium by microscopic analysis. This will prevent the systematic use of biopsies which are often difficult and iatrogenic.

NCT ID: NCT02140970 Completed - Urolithiasis Clinical Trials

Randomized Trial of NSAID vs Placebo Prior to Ureteral Stent Removal

Start date: May 2014
Phase: N/A
Study type: Interventional

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.
