Analysis the Relationship Between the Abdomen CT and Outcomes in Acute Urinary Stone Patients
Urinary CalculiEmergency Service1 moreThis is an observational study based on retrospectively collected data of ureter stone patients between 2011 and 2014. Aim of study is to determine radiologic findings of non-contrast abdominal computerized tomography as predicting clinical outcomes of suspect ureter stone patients in emergency department (ED).
Proteomic Study of Urinary Stone Disease
Urinary CalculiHyperoxaluria1 moreUrinary protein levels are not routinely measured in stone patients while there is strong evidence that proteins play a role in the etiology of stones. The purpose of this study is to examine the urinary and serum proteins of stone formers compared to healthy subjects utilizing the high throughput method, Surface Enhanced Laser Desorption/Ionization (SELDI). We hypothesize that there is a unique set of proteins expressed in serum and urine in stone patients that can be detected by SELDI. Ultimately, this will better our understanding of stone disease and help develop new prevention strategies.

US-Non Contrast Computed Tomography Real-time Fusion for Urinary Stones Follow up
UrolithiasisUreterolithiasisUrolithiasis is a universal problem, a large part of patients will be affected by multiple stones throughout their lifetime, with estimated recurrence rates of 75% within 20 years. The high recurrence rate requires an increasing amount of imaging follow-up. US-NCCT real-time fusion (Fusion) enables lesion assessment and follow up using both modalities as reference for each other. Our study proposes a novel approach for short term follow up of patients using Fusion instead of repeat NCCT exams. the goal of the study is to create an initial proof of concept that Fusion is effective for follow up of known urinary stones. the study is a prospective study on Patients with an obstructing ureteral stone found on a NCCT. Patients will undergo Fusion (using General Electric Logiq E9) after NCCT. The primary endpoint was the ability to locate the ureteral stone using US with guidance of the NCCT as a "Road Map".

UrolithiasisUrologic Diseases38 moreTo investigate the effectiveness of percutaneous nephrostomy catheter placement versus retrograde double J catheter placement in patients with symptoms of obstructive kidney disease (with either infection and/or pain and/or kidney function deterioration) caused by urolithiasis.
Multi-Center Comparison of Dual Lumen Versus Single Lumen Ureteroscopes
UrolithiasisUrolithiasis (kidney stones) is a common disease process affecting people all across the world. Usually, if the stone size is small, it is able to pass through the urinary system and exit the bladder on its own with no treatment. However, when the size of the stone is bigger, it can get trapped in the kidney or the ureter, causing significant pain for the patient and potentially obstructing urine flow. If this occurs, surgical treatment is necessary for the removal of the stone. The surgical procedure often employed involves the use of a ureteroscope, which is a device that includes a camera and channels for working instruments such as a grasper and laser fiber to be placed during a procedure. Ureteroscopes that are currently in use are flexible and have the ability to treat stones that may otherwise be inaccessible in the kidney. Most flexible ureteroscopes in clinical use currently only have one channel therefore only allowing one instrument to be used at a time. Recently, a new type of ureteroscope has been introduced in the market that offers the advantage of having two working channels where two instruments can be inserted for use during stone treating procedure. This can potentially decrease procedure time for patients affected by kidney stones. The purpose of this research is to compare the efficacy and safety of the ureteroscopes that have only one channel for instrument insertion with the newer ureteroscope that has two channels for utilization during stone treatment.
Metabolic Assessment of Aging Men With Urinary Lithiasis
Urolithiasis and AgingRenal Calcul and Metabolic Diseases1 moreUrinary lithiasis is a common disease on young adults, but not so far on aging people. Nowadays, the investigators are seeing a gradative growth on men above sixty years old, mainly in industrialized countries. The purpose of this study is to investigate metabolic aspects of aging men with renal stones, towards blood tests, 24 hour-urinary samples, imagenological exams and bone densitometry. The investigators have made a case-control model.
