Filter by:The goal of this work is to assess the best time to perform LC combined with LCBD exploration and the feasibility and safety of such procedure in patients with combined GBS and CBDS after failure of ERCP extraction of CBD stones .
to compare efficacy and safety of Silodosin and Tamsulosin in Medical expulsive therapy of Distal Ureteric Calculi.
Assessment of the differences in stone size and the largest CBD diameter before and after stenting in one or two sessions. Stone clearance and complications were also determined with the ERCP, and factors associated with complete clearance were evaluated in patients with difficult CBD stones (a large [≥ 20 mm] or multiple [≥ 3 sized ≥ 15 mm] CBD stones). And also compared the outcomes with conventional procedure of open surgery.
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.
The management of gallbladder stones (lithiasis) concomitant with bile duct stones is controversial. The management of CBD stones has evolved considerably since the advent of laparoscopic surgery. The more frequent approach is a two-stage procedure, with endoscopic sphincterotomy and stone removal from the bile duct followed by laparoscopic cholecystectomy. The laparoscopic-endoscopic rendezvous combines the two techniques in a single-stage operation. So the aim of this study was was to evaluate one-stage LC with intra-operative endoscopic sphincterotomy (IOES) vs two-stage pre-operative endoscopic sphincterotomy (POES) followed by LC for the treatment of cholecystocholedocholithiasis.
Extracorporeal shock wave lithotripsy (ESWL) is the least invasive and effective treatment for upper ureteric stones with a stone clearance rate of 60-90%. Tamsulosin is an alpha-blocker widely used in urological practice to relax smooth muscle of the prostate and bladder neck. Its role as part of medical expulsion therapy for the treatment of patients with kidney and ureteric stones has proved to be of considerable success. However, its role in clearing upper ureteric stones as an adjunct to ESWL is controversial. Therefore, this study will be conducted to evaluate its role in stone clearance along with extracorporeal shock wave lithotripsy in patients with upper ureteric stones
Due to the anatomic characteristics of the lower calyx, lower pole stones are difficult to be eliminated through the ureter, even if the stones had been fragmented. Retrograde intrarenal surgery (RIRS) can be used to deal with lower pole stones of 1.0-2.0 cm, while percutaneous nephrolithotripsy (PCNL) is mainly used to deal with lower pole stones with larger diameter or when RIRS failed to resolve the stone. This study was conducted to compare mini PCNL and retrograde intrarenal surgery (RIRS) for the management of lower pole kidney stones in terms of efficacy.
The purpose of this study is to use the Shuotong ureteroscopy for surgical treatment of patients with upper urinary tract stones, taking advantage of the fact that the Shuotong mirror can be used for simultaneous lithotripsy and stone removal, thus maximizing the discharge of stones from the body and improving the stone removal rate.
The goal of this clinical trial is to test the Break Wave™ system in patients with upper urinary tract stones. The main question it aims to answer is whether the device is safe and effective in fragmenting (breaking) stones. Participants will a) undergo the Break Wave™ procedure, b) have a telehealth visit at 2 weeks, and c) return for an imaging study at approximately 10 weeks post-procedure.
The purpose of this study is to evaluate the safety of eating 6 hours after Extracorporeal Shock Wave Lithotripsy (ESWL). At present, ESWL and Endoscopic Retrograde Cholangiopancreatography (ERCP) are the routine ways to treat pancreatic duct stones. For large stones (diameter > 5mm) , ESWL often needs to be performed many times. In clinical practice, fasting for 24 hours after surgery is often used, but long-term fasting brings strong discomfort to patients. However, the consensus for initiation timing of oral nutrition has not yet been established after ESWL. Thus, we design this trial to evaluate the safety of early feeding based on 6 hours parameter instead of the consensus definition.
