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: NCT05240170 Recruiting - Renal Calculi Clinical Trials

RIRS for Treatment of Stones in Congenital Anomalous Kidneys

Start date: March 15, 2022
Phase: N/A
Study type: Interventional

The anatomic renal abnormalities like altered spatial relations with adjacent organs, abnormal calyceal orientation, and anomalous vascular patterns make the active treatment of stones in the congenitally malformed kidney a great challenge for urologists. In this prospective study, the investigators will evaluate the outcome of retrograde intrarenal surgery (RIRS) with extracorporeal shockwave lithotripsy (SWL) for the treatment of stones in the kidneys with rotation or position anomalies.

NCT ID: NCT03206515 Recruiting - Renal Calculi Clinical Trials

The 18F Peel-way Sheath Versus the 18F Access Sheath With a Suction-evacuation Function MPCNL for the Management of 2-5cm Size Kidney Stones

Start date: January 2016
Phase: N/A
Study type: Interventional

Percutaneous nephrolithotomy (PNL) has been considered as the first-line choice for the management of >20mm kidney stones. Microchannel percutaneous nephrolithotomy (Mini PCNL) which takes nephrolithotomy channel size less than or equal to 18, was first used in the treatment of children with kidney stones in 1997, then gradually applied to adult, aims to achieve the similar stone clearance rate as the standard channels, at the same time, reduce the complications. At present, the use of percutaneous renal surgery in our country is more than 18F plastic peel-away sheath, with the access sheath with a suction-evacuation function was first used by Guohua Zeng and so on. But there is still a lack of high quality evidence of Evidence-based medical evidence to compare the two kinds of sheath for the safety and effectiveness. Therefore, this study provides a reliable theoretical basis for the choice of the sheath for the treatment of 2-5cm size Kidney, and ultimately benefit patients with 20mm.

The Influence of SMP on Renal Pelvic Pressure In Vivo

Start date: April 2016
Phase: N/A
Study type: Interventional

Percutaneous nephrolithotomy (PCNL) is a well-established treatment modality for renal stones. It offers a high stone free rates and less invasive than open surgery. Nevertheless PCNL is an invasive and technically demanding procedure with inherent risks and complications. The most troublesome morbidities are bleeding and injury to the kidney and its adjacent structures. Complications of PCNL tend to be associated with the accuracy of tract placement and the size of the nephrostomy tract. To improve the safety of PCNL, there is a trend toward using smaller and smaller nephrostomy tracts . With the smaller nephrostomy tract, there also arise the problems of compromised visual field and increased difficulty in stone extraction. Increase irrigation using pressure pump might improve the visualization and the passive egress of the stone fragments, but it also may concomitantly increase the intra-luminal pressure. The present system of Super-Mini percutaneous nephrolithotomy (SMP) was developed to address many of these deficiencies. The basic components of SMP system are an 8.0 F miniaturized nephroscope with a newly designed irrigation-suction sheath with enhanced irrigation capability and modified nephrostomy sheath with continuous negative pressure aspiration. Its design was intended not only to prevent the excessive intrarenal pressure but also improve the visualization and the stone fragments extraction. Little was known about renal pelvic pressure in vivo during SMP and about any correlation it might have had with postoperative fever and urosepsis. We measure the renal pelvic pressure during SMP to determine whether it will improve the renal pelvic pressure and improve the incidence of postoperative fever.

External Physical Vibration Lithecbole(EPVL) Versus Traditional Row of Stone After Retrograde Intrarenal Surgery(RIRS)

Start date: August 2015
Phase: N/A
Study type: Interventional

The treatment of renal calculus by retrograde intrarenal surgery(RIRS) isn't able to eliminate stone completely, hastening fragments clearance just only rely on traditional expulsive methods such as high fluid intake ,increasing physical activity, medical expulsive therapy and changing body position. Therefore, researchers purpose to evaluate the effectiveness of external physical vibration lithecbole(EPVL) in treatment of residual fragments after RIRS by prospective study of clinical trial, which will improve stone-free rate of residual fragments and benefit more patients.
