Filter by:Current urological therapeutic modalities are represented by extracorporeal lithotripsy (ECL), rigid (URS) or flexible (URSsple) uretero-renoscopy and percutaneous nephrolithotomy (PCNL). They make it possible to extract the vast majority of stones by minimally invasive techniques but leave behind small residual lithic fragments (FR) that can always cause pain, infection, or promote the development of a larger stone. A non-invasive technique that can help eliminate them would be of great benefit to many patients by avoiding painful recurrences and limiting reprocessing; combined with appropriate medical management, it would limit the rate of remote recurrences and long-term complications. The treatment called "hydro-posturotherapy" has been developed in some spas that are approved for kidney diseases such as Vittel or Capvern. It includes several modalities: posturotherapy, lumbar percussion and hyperdiuresis. The main objective is to compare at 3 months, on the unprepared abdomen (ASP) and the low-dose scanner without injection, the elimination of kidney stone fragments under the effect of a short spa treatment with posturotherapy, lumbar percussion and controlled hyperdiuresis compared to the recommended standard treatment. The result will be assessed in 3 categories: complete elimination (SF: "without fragments" or "stone-free"), elimination of more than 50% of the fragments; elimination of less than 50% of the fragments.
This is a single arm, single center study to assess the safety and efficacy of a form of extracorporeal lithotripsy, called the Enhanced Lithotripsy System, to treat urinary stones.
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 refinements in stent technology and usage philosophy. Smaller and softer stents are now available for use in patients, though studies evaluating the relative benefits have been conflicting. The investigators aim to evaluate the effect of stent size and composition upon outcomes after the treatment of stone disease, including patient comfort and satisfaction.
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 to ureteroscopy without use of a sheath.
