The specific aim of this study is to validate our hypothesis that the magnetic ureteral stents have the same amount of adverse effects as the more commonly used non-magnetic ureteral stents. If this hypothesis would be confirmed then the usage of magnetic ureteral stents would be justified for both reducing patient discomfort by way of fewer cystoscopies and possibly also decreasing the overall expenditures of treatment.
JJ ureteral stents are often positioned at the end of a ureteroscopy and often cause important comorbidities. Indeed, up to 80% of the patients complain a deterioration of the quality of life. In order to reducing the symptoms to the minimum, the producing companies developed different types of stents, hypothetically thinking that modifications in materials and designs might reduce patients' discomfort. Classic ureteral stents have a proximal J and a distal J as anchors respec...
Traditional ureteral stents are commonly used in renal and ureteral procedures, and their use is associated with many morbidities which can affect patients' quality of life. However, replacement of the distal portion of the stent with a thin material may reduce bladder irritative symptoms and allow the ureterovesical junction to coapt---thereby, reducing urinary reflux. The hypothesis is that the RELIEF stent will offer the same function of traditional ureteral stents with the ...
The purpose of this study is to determine the clinical effects of a triclosan stent on adherent bacteria, stent biofilms, and patient urine cultures in patients with an indwelling triclosan ureteral stent. The patient populations that will be tested include: patients following ureteroscopy, patients who require chronic long-term stenting, and patients scheduled to undergo shockwave lithotripsy who require a ureteral stent. It is hypothesized that triclosan eluting ureteral ste...
A thin tube, called a ureteral stent, is inserted into the ureter and is commonly used as treatment of urinary stone disease. Stents are designed to help provide drainage of the kidney in the setting of an obstructing stone, or postoperative swelling of the ureter. Though their presence is only temporary, stents are associated with a significant amount of patient discomfort and bother, which can negatively impact overall satisfaction. Over the past decades, there have been ref...
JJ ureteral stents are often positioned at the end of a ureteroscopy and often cause important comorbidities. Indeed, up to 80% of the patients complain a deterioration of the quality of life. In order to reducing the symptoms to the minimum, the producing companies developed different types of stents, hypothetically thinking that modifications in materials and designs might reduce patients' discomfort. Talking about materials, most ureteral stents are made up of polymers, esp...
Background: The exit strategy after ureteroscopy for stone treatment remains a topic for discussion. Current EAU guidelines on urolithiasis state that postoperative stenting is indicated in patients at increased risk of postoperative complications. Stenting is not considered necessary in all other cases, and after uncomplicated procedures. Objective: To analyse the postoperative ureteral stenting strategy in clinical practice looking at the indication, type of stents used and ...
This study is a prospective, randomized multicenter study conducted in Europe. It is designed to compare two double loop ureteral stents in terms of the quality of life in patients operated on a kidney stone and requiring the placement of a double loop ureteral stent at the end of the operation.
The purpose of this study is to evaluate the safety and efficacy of the Memokath 051 ureteral stent as a long-term temporary and minimally invasive means of providing ureteral drainage in the setting of malignant extrinsic ureteral obstruction secondary to inoperable abdominal or pelvic malignancies. Up to 15 adults who have extrinsic ureteral obstruction secondary to an inoperable abdominal or pelvic malignancy and need ureteral stent drainage will undergo outpatient placemen...
The purpose of this study is to assess whether one of two ureteral access sheaths is safer for patients undergoing ureteroscopy. Both sheaths are FDA approved devices and commercially available. We will compare the ability of sheaths to access the kidney through the ureter and will compare damage done to the ureter after completion of the procedure. Access sheaths are standard of care for this procedure; this study seeks to optimize outcomes for patients. Patients undergoing u...
This is a single institution, prospective study to evaluate the prognostic significance of renal and bladder ultrasound with ureteral jet assessment and its utility to evaluate the spontaneous stone passage rate of ureteral stones.
The objective of this project is to compare the efficacy of hyoscyamine to tamsulosin monotherapy in treating lower urinary tract symptoms in patients with indwelling double-J ureteral stents.
Patients with upper ureteral or renal stones will be randomized to undergoing ureteroscopy with or without a ureteral access sheath. The sheath is designed to facilitate ureteroscope insertion and re-insertion, thus allowing fragments to be basketed out. Stone free rates at 3 months will be determined between the two groups. The investigators hypothesize that the use of the ureteral access sheath with ureteroscopy will result in improved stone free rates at 3 months compared ...
Cryo AF Global Registry a prospective, global, multi-center, observational Post-Market Registry
The purpose of this study is to evaluate the feasibility of the Cook Ureteral Stent to reduce post-stent placement pain and urinary symptoms in patients following ureteroscopy for urolithiasis.
This study (FORECAST 2) builds upon the work of the successful pilot study (FORECAST) that found some evidence that breast cancer patients' fears of cancer recurrence (FCR) were sensitive to the communication exchange with therapeutic radiographers during weekly review appointments. The aim of FORECAST 2 is to co-design and pilot a communication training package for therapeutic radiographers to help them manage emotional talk with breast cancer patients who are undergoing treat...
The primary objective is to describe the safety and efficacy of intravenous sodium fluorescein to visualize ureteral efflux during intraoperative cystoscopy after total laparoscopic hysterectomy. Secondary objective is to report on surgeon's satisfaction with the overall use of sodium fluorescein.
The purpose of this study is to determine the efficacy of the α-adrenergic antagonist tamsulosin in the treatment of adult emergency department (ED) patients with ureteral colic secondary to lower ureteral calculus. We hypothesize that there will be no difference in outcomes for subjects treated with and without tamsulosin.
The purpose of this study is to determine whether the use of drug eluting stents is associated with higher rates of death, myocardial infarction, and major bleeding. In addition, the overall economic costs of implanting drug eluting stents compared to bare metal stents will be assessed.
The introduction of one dose of the inactivated poliovirus vaccine (IPV) into routine immunization schedules in OPV-only using countries as part of the Global Polio Eradication Initiative (GPEI) was planned for completion in 2016. However, due to recent developments in the global IPV supply landscape, the GPEI polio eradication program is facing a critical shortage of the vaccine which is forecast to continue until at least the end of 2017. The shortage means that some countrie...
Non-malignant causes of ureter obstruction can be intrinsic such as stone disease, ureter stricture or congenital ureteropelvic junction obstruction, or extrinsic such as idiopathic retro peritoneal fibrosis. Nearly all clinicians agree that obstructing stones, with a concern for sepsis require immediate decompression of the urinary system. Though large epidemiologic studies of the management of obstructed infected nephrolithiasis demonstrate higher rates of sepsis and mortali...
The present study aims to investigate the relative efficacy, safety and risk of a single-dose prophylaxis in otherwise healthy adult patients undergoing ureteroscopic procedures for ureteral stones.
The Study of whether or not Ureteral Stent Length affects patient comfort after electro-shock wave treatment for kidney stones.
Ureteral stones have an important place in daily urological practice, usually causing acute episodes of ureteral colic by obstructing the urinary tract. The aim of the study is to evaluate whether repeated administration of tamsulosin, a drug routinely used in the treatment of lower urinary tract symptoms, could lower the delay of elimination of the stone in patients with pelvis ureterolithiasis.
To assess the impact of alfuzosin vs. placebo on ureteral stent discomfort, urinary symptoms and quality of life.
