Filter by: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.
to compare outcome of pyeloplasty in pediatric population less than 6 months in age using an after coming stent versus stentless pyeloplasty.
The purpose of this study is to assess the clinical significance of supranormal differential renal function (DRF) in the recovery of unilateral hydronephrosis (HN) after surgery, pediatric patients who underwent pyeloplasty for ureteropelvic junction obstruction (UPJO) who showed supranormal DRF (> 55%) in the DTPA renography will be analyzed.
Pediatric upper urinary tract dilatation (hydronephrosis) is relatively common and may be either obstructive or nonobstructive. While the upper urinary tract is commonly evaluated by ultrasound, this imaging technique often fails to distinguish obstructed from nonobstructed systems. ARFI SVI is a new ultrasound technology that can be used to determine stiffness by measuring a tissue's shear wave velocity, may show alterations in parenchymal shear wave velocity in kidneys that show obstruction on DRS (Diuretic renal scintigraphy)which serves as the reference standard.
Kidney stones cause severe pain. Patients with a stone lodged in the ureter (the tube that drains the bladder), require urgent treatment with a stent to relieve the blockage. This tube, or ureteral stent, gives the patient relief until they can have their stone treated. This study is to evaluate a new type of ureteral stent to relieve pain from kidney stones. This stent is designed to drain the kidney and unlike other ureteral stents, is also designed to widen the ureter to help the stone pass on its own.
Proper selection of ureteral stent length might help in reducing comorbidities associated with ureteral stenting, currently there is no standardized way of measuring ureteral length. Measurement of ureteral length according to Computed Tomography (CT) scan might provide useful information when selecting the length of a ureteral stent. Our aim in this study is to compare ureteral measurements using CT scan and measurement of actual ureteral length measured during ureteral stenting.
The purpose of this study is to determine the overall sensitivity and specificity of hydronephrosis on point-of-care bedside ultrasound to identify hydronephrosis as compared to hydronephrosis found by CT.
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.
Renal colic is a common (1300 visits per year at our institution) and painful condition caused by stones in the kidney and ureter, and can be mimicked by life threatening conditions such as a ruptured abdominal aortic aneurysm (AAA). This can create clinical uncertainty. Emergency department targeted ultrasound (EDTU) is performed by an emergency physician at the patient's bedside, and has been shown to be accurate, safe, and efficient. We have shown that EDTU can accurately identify hydronephrosis, which is a predictor of complications of kidney stones. A normal formal ultrasound (US) predicts an uncomplicated clinical course. We will assess the accuracy of EDTU for the diagnosis of hydronephrosis, and when normal, whether patients can be safely discharged.
Performance and outcomes measure are, at this time, relatively unknown for robotic pyeloplasty procedures. The purpose of this study is to provide a clearer understanding of the urology department's robotic pyeloplasty quality and outcomes measures. This will be accomplished by prospectively collecting data for these procedures would ensure that measures are consistently collected in accordance with a defined protocol, allowing for more valuable quality and clinical research analysis. Hypothesis will be defined before data analysis is performed. Amendments specifying future hypothesis will be submitted the IRB at the appropriate time.
