Filter by:To determine if the effects of MOSES laser modulation technology can improve the safety and efficiency to laser fragmentation resulting in decreased total laser time, reduced potential for injury to the patient, and total OR time and utilization.
Cholelithiasis occurs in 10-20% of the general population. Up to 18% of these subjects will present symptoms. In patients with symptomatic choledocholithiasis who are not candidates for surgery with indication for ERCP, transmural drainage of the gallbladder reduces the risk of recurrence. The investigators propose a multicentric double-blind randomized trial. Our primary objective is to assess whether ERCP associated with transmural gallbladder drainage is able to reduce biliary disease income compared with ERCP in patients not candidates for surgery with symptomatic choledocholithiasis and cholelithiasis during one year of follow-up. Also the investigators will analyze the proportion of technical success and complications. The study population includes all patients older than 75 years with symptomatic choledocholithiasis. An estimated 75 subjects per group (ERCP alone and ERCP and transmural drainage) are needed.
We are studying the possibility of using dental calculus as a reservoir for the genes of an infectious agent that has infected the patient in previous months; as it is done to highlight climate change in ice samples.
The rationale for this study is to determine if there is a difference in complications among patients undergoing ureteroscopy for renal stones who receive a stent compared to not receiving a stent postoperatively.
Ultraslow full-power SWL versus slow power-ramping SWL in Renal stones with high attenuation value
The purpose of this study is to determine whether the magnetic compressive anastomosis has a better outcomes than traditional manual anastomosis on bilioenteric anastomosis.
The investigator aims to perform a prospective and randomized controlled trial evaluating the safety and efficacy of External Physical Vibration Lithecbole(EPVL) in treating 4-10 mm ureteral stone.
This is a two arm, double blind RCT comparing the use of a single dose ciprofloxacin prior to SWL to saline alone. The multicenter trial will be conducted with a pragmatic emphasis including both high volume and low volume sites internationally.
Advancements in technology and endourological armamentarium provides multiple surgical options for complicated stone patients. To avoid multiple operations and shorten the total operation durations, bilateral synchronous simultaneous stone surgery (BSSSS) has been popularized in recent years. Our aim is to evaluate the preliminary outcomes of BSSSS in patients undergoing supine percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS).
ABSTRACT Introduction: Common bile duct (CBD) stone is a common clinical situation, especially in Asia area. Laparotomy and laparoscopic surgical procedure are often used for treatment. This study compares outcomes of different surgical procedures treating for the disease. Methods/design: This is a prospective, randomized, controlled multicenter trial with three treatment arms. One group underwent laparoscopic cholecystectomy (LC) + laparoscopic CBD exploration (LCBDE) + intraoperative endoscopic nasobiliary drainage ENBD + primary closure of CBD. The other underwent preoperative endoscopic retrograde cholangiopancreatography (ERCP) and subsequent LC and the third arm underwent laparoscopic cholecystectomy (LC) + laparoscopic CBD exploration (LCBDE) + primary closure of CBD. The duration of the entire trial is two years including prearrangement, follow-up and analyses. Discussion: Despite the fact plenty evidences provided by meta-analyses suggests that these approaches would appear comparable. It is hopeful to fully address which would be the better approach with this RCT design.
