The Efficacy and Safety of Chinese Domestic Surgical Robot System in Urological Telesurgery

Start date: February 5, 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05738304 Recruiting - Kidney Stone Clinical Trials

Ureteral Stenting After Retrograde Intrarenal Surgery for Renal Stones

Start date: January 12, 2021
Phase: N/A
Study type: Interventional

Several studies evaluated the benefit of a short-term external ureteral catheter (UC) compared to double-J (DJ) ureteral stent after flexible ureteroscopy (URS); the results were controversial. These studies had combined analyses of ureteral and renal stones with a high risk of selection bias. Studies comparing external UC and DJ stent after flexible URS for isolated renal stones are lacking. In the present study, the investigators will compare the outcomes of using a one-day external UC versus a DJ internal ureteral stent for ureteral drainage after retrograde flexible URS (retrograde intrarenal surgery "RIRS") for renal stones. The investigators aim to identify the best ureteral drainage method after RIRS regarding stone clearance, complications, and stent-related symptoms.

NCT ID: NCT05701098 Recruiting - Urolithiasis Clinical Trials

SOUND Pivotal Trial - (Sonomotion stOne comminUtion resoNance ultrasounD)

SOUND
Start date: October 9, 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05697250 Recruiting - Renal Stone Clinical Trials

High Versus Low Power Settings During Ureteroscopic Laser Lithotripsy

Start date: January 23, 2023
Phase: N/A
Study type: Interventional

The primary aim of the study is to compare the operative times following ureteroscopic lithotripsy for renal stones with Thulium Fiber Laser using low and high power settings. Secondary aims are to compare the results of low and high power settings in terms of stone free rates, laser time, laser activation patterns, intraoperative and postoperative complications. Patients ≥ 18 years with renal stones (8-25 mm) scheduled for ureteroscopic lithotripsy at the Day Surgery Clinic at Haukeland University Hospital in Bergen, Norway, are eligible for inclusion in the study. After written consent and inclusion, patients are randomised to laser lithotripsy using either low power settings (Group 1: 4-6 Watt, short pulse mode) or high power settings (Group 2: 16-18 Watt, short pulse mode). The ureteroscopic procedures are performed in general anaesthesia using a standardised technique. All patients are followed up with a low dose CT scan 3 months post endoscopically to assess stone free status as well as a consultation at the outpatient clinic. Results and data for the two randomisation groups are compared according to the aims of the study.

NCT ID: NCT05648877 Recruiting - Clinical trials for Retrograde Intrarenal Surgery In Management Of Renal Stones

to Study the Role of Retrograde Intrarenal Surgery in Management of Renal Stones

Phase:
Study type: Observational

- Reporting prevalence of uric acid based renal stones among patients with nephrolithiasis admitted to Mansoura Urology and Nephrology center (MUNC). - Furthermore, identification of monogenic and polygenic uric acid stone formers. - Identification of factors associated uric acid stone recurrence as well as determinants of laterality in patients with uric acid based renal stones

NCT ID: NCT05598671 Recruiting - Kidney Calculi Clinical Trials

Percutaneous Nephrolithotomy Without a Ureteral Catheter

Start date: November 3, 2022
Phase: N/A
Study type: Interventional

Conventional Percutaneous nephrolithotomy (PCNL) surgery requires the patient to first undergo retrograde transurethral ureteroscopic insertion of the ureteral catheter in the lithotomy position, and then change the patient to the prone position. However, repeated operation on the ureter can bring about immediate and long-term negative effects, such as ureteral false way formation, ureteral damage, perforation, avulsion, catheter insertion into the vena cava, pricking the kidney, increased postoperative pain, urinary extravasation, scar formation, and ureteral narrowing. The study planned to perform the operation in the prone position without reverse insertion of a ureteral catheter in the PCNL surgery.

Start date: August 16, 2022
Phase: N/A
Study type: Interventional

This study aims to compare the efficacy and safety of both types of lasers, Holmium MOSES and TFL, in management of kidney stones requiring treatment.
