Filter by:The study evaluate the damage effect of ESWL and PCNL on kidney tissue by measuring non-coding lnc-RNA profile in urine before and after ESWL and PCNL procedures
This multi-center trial is being completed to compare patient outcomes related to the Imajin silicone stent in comparison to non-silicone polyurethane stents after ureteroscopy. Eligible participants will be enrolled and randomly assigned to receive the Imajin silicone stent or a non-silicone stent. In addition, the participants will complete questionnaires and have follow-up information collected (approximately 60 days after surgery). The trial hypothesizes that a ureteral stent made of silicone, will have superior outcomes when compared to non-silicone stents.
The corticomedullary gradient is largely responsible for developing the gradients that are needed to concentrate urine (more solutes and less water). The ability of the kidneys to produce concentrated urine is a major determinant of the ability to survive the warm weather. When temperatures are high, we lose water through sweat, and so the kidneys retain water to maintain fluidity in the blood. The maintenance of a sodium (salt) gradient is required for urine concentration because increased medullary sodium concentration increases the reabsorption of water into the kidney, to be redistributed in the blood. The purpose of this study is to know if the corticomedullary gradient is altered in patients across a wide spectrum of kidney disease using sodium Magnetic Resonance Imaging (MRI), a machine that takes pictures and measures the salt content in the kidneys. 23Na kidney MRI, will provide functional MR of the kidney as a non-invasive tool to describe medullary function to improve management of chronic and kidney disease.
To compare the efficacy of Ultrasound guided thoracic paravertebral block versus ultrasound guided caudal epidural block in pediatric patients undergoing percutaneous nephrolithotomy
The purpose of this study is to determine the differences in stone free results, patient side effects, and patient satisfaction between dusting vs. basket extraction for kidney and ureteral stones (a kidney stone located in the tube between the kidney and bladder) 6 mm and greater in size undergoing ureteroscopic treatment. Dusting is when a laser is used to break a stone down into tiny fragments that are able to pass through the urine. Basket extraction is when a small wire basket is used to remove stone fragments.
To compare intraoperative as well as postoperative outcomes of SOLTIVE Thulium laser compared to Ho:YAG laser for the treatment of urolithiasis. The hypothesis is that utilizing the SOLTIVE Thulium laser for the treatment of urolithiasis will result in a more efficient procedure, with comparable stone free rate to that of Holmium laser and subjective improvement in physician satisfaction.
The goal of this study is to gain new knowledge about genetic risk factors that may affect the kidney stone recurrence. The study seeks to understand if different forms of genes result in an increased risk of kidney stone recurrence.
Flexible ureteroscopy has become the main surgical treatment for kidney stone disease. The procedure uses many types of ureteroscopes (disposable and non-disposable). Currently we are using the LithoVue Single-Use Digital Flexible Ureteroscope. The Health Canada approved LithoVue Elite disposable flexible ureteroscope will now offer novel pressure sensory capacity. In order to evaluate the new ureteroscopy we will be conducting a prospective multi-institution study in order to determine the main features, capacity and abilities of the new scope. We will evaluate the impact of intra renal pressure on pain, quality of life and possible infectious complications.
The study is a randomised trial of hypnosis with 3D virtual reality headset (intervention group) versus control group with no hypnosis and no virtual reality headset to compare remifentanil consumption during shock wave lithotripsy.
The optimal management of medium-sized renal stones remains quite challenging and continues to be contested. In the present study, the investigators will compare mini-PNL, RIRS and SWL in the treatment of non- lower pole, medium size, high dense renal stones regarding the stone-free rate, the safety of the procedures, cost, and patients' and surgeon's satisfaction. Eligible patients will be randomly allocated into three equal groups (mini-PNL, RIRS, and SWL). Postoperative, patients will be followed-up by regularly for 3 months. The study parameters will be compared between groups.
