Active clinical trials for "Kidney Calculi"

This study is looking to understand the role of oxalate on kidney stone development and immunity. This study will enroll healthy participants and participants with calcium oxalate kidney stones (CaOx KS). Participants will be in this study for about 3 weeks, consume controlled diets, and provide blood and urine specimens.

This is a prospective, double-blind, randomized, open-label, single-center trial of up to 78 participants who are adult patients (aged 18-80 years) and are undergoing unilateral retrograde ureteroscopy with planned ureteral stent placement for treatment of urinary tract stones. Eligible patients will be randomly and divided into two groups in a 1:1 ratio. Group A will receive fexofenadine 180 mg once daily in addition to standard of care treatment. Group B will receive placebo in addition to standard of care treatment. The routine standard of care treatment will consist of oral non-steroidal anti-inflammatory drugs (NSAIDs). The primary outcomes of the study are the Ureteral Stent Symptom Questionnaire (USSQ) urinary symptom score and pain score. Secondary outcomes include (i) number of office phone calls due to urinary symptoms; (ii) duration of analgesic use; (iii) duration and quantity of narcotic use; (iv) number of emergency department visits; (v) drug-related adverse effects; (vi) other domains of the USSQ.

The investigators will randomize overweight and obese iuan patients to Pio (45 mg/day, highest approved dose or placebo), WL (10% of body weight, following the established program used in the Diabetes Prevention Program), or Pio+WL. Participants will be evaluated at baseline and after 24 weeks of intervention while on a fixed metabolic diet to exclude the confounding effects of diet and perspiration. The primary endpoint will be change in upH, and multiple additional endpoints (serum, urine, imaging) will be assessed.

A single-arm clinical trial was designed in this study. The surgeon will perform urological telesurgery for patients using Chinese domestically produced "MicroHand S" surgical robot system. The "MicroHand S" surgical robot system consists of two physically separated subsystems named the "surgeon console" and the "patient side cart". The surgeon console includes a stereo image viewer, two master manipulators, a control panel and several foot pedals. The patient side cart includes a passive arm that can slide in the up-down direction and be adjusted forward and backward, a swivel head that can rotate around the vertical axis, and three slave arms. In addition, surgical instruments and sterile bags are the essential accessories for the "patient side cart". The principle of the telesurgery is as follows: the surgeon console takes the surgeon's input and translates manipulation into a control signal. After network transmission, the signals will be received by the patient side cart and will be used to control the slave robot to manipulate the instruments to perform the operation within the patient's cavity. The 3D images captured by the endoscopic camera will be simultaneously sent back to the screen of the surgeon console as visual feedback. Data between the surgeon console and the patient side cart will be transmitted through a 5G network or other advanced network networking scheme. The surgeon remotely manipulates the slave arms and performs surgeries for patients in remote areas. The safety and efficacy of the robot system in remote clinical treatment will be verified by the primary and the secondary evaluation criteria. One hundred patients with urological diseases will be enrolled in the clinical trial. Primary evaluation criterion: The success rate of the surgery. Surgery success is defined as that all surgeries are performed remotely and safely without transfering to other types of surgery, such as open surgery or normal robot-assisted surgery. Secondary evaluation criteria: Operative time, blood loss, postoperative pain, preoperative adjusting time, hospitalization time, average network latency, task load, peer recognition, anxiety index. Patient enrollment: This experiment aims to investigate the safety and effectiveness of the domestic robot system in clinical urological surgery under the current network networking scheme. It is planned that 100 patients with urinary system diseases will participate in the clinical trial.

A feasibility study to test the ability to move kidney stones using focused ultrasound. It is the goal of our technology to: a) move stone fragments to a location within the kidney to improve their chances of passage, and thus reduce the occurrence of additional symptomatic events and retreatment or b) move a symptomatic stone to relieve symptoms and pain.

Burst Wave Lithotripsy (BWL) is a novel method of urinary stone fragmentation that uses multi-cycle bursts of low amplitude ultrasound to induce stone fracture. This is in contrast to traditional extracorporeal shock wave lithotripsy (SWL), which employs a brief single compression/tensile cycle of high amplitude (shock) waves to achieve stone fracture. This is a single-arm feasibility study to test the ability of BWL to comminute (fragment) stones in humans.

The purpose of the study is to compare the effects, good and/or bad, of a treatment for removing kidney stones called the SURE procedure for stone evacuation to the standard treatment using a basket for stone removal.

This is a randomized, placebo-controlled, double-blinded study examining the use of perioperative pregabalin in ureteroscopy with stent placement. Ureteroscopy is typically performed for kidney or ureteral stones, but may be performed for other reasons such as for the diagnosis and possible treatment of certain kinds of cancers. As part of the same surgery, a ureteral stent is often placed. The surgery and the stent can cause discomfort, and patients may receive narcotic pain medicine. In other surgeries, a single dose of pregabalin, around one hour before surgery has been shown to decrease the need for pain medication after the surgery. This work will test whether this is true in ureteroscopy by giving eligible patients who agree to participate either pregabalin or a placebo shortly before surgery then examining how much pain medication they use after surgery. A placebo is an inactive medication. Neither the study participant nor the study staff will know who received pregabalin and who received placebo until after the study is over. For completing surveys, patients will receive compensation for their time in the form of gift certificates.

The purpose of this study is to collect real-world evidence on the performance of the SOLTIVE™ Premium SuperPulsed Laser System for laser lithotripsy in ureteroscopy, percutaneous nephrolithotomy (PCNL) and mini PCNL for kidney and ureteral stones.

The aim of this study is to evaluate the clinical efficacy and safety of MET after ESWL in pediatric urolithiasis.
