NCT ID: NCT05739812 Recruiting - Prostate Cancer Clinical Trials

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: NCT04111692 Recruiting - Clinical trials for Autosomal Dominant Polycystic Kidney

A Prospective Observational Study of Foam Sclerotherapy .

Start date: November 6, 2017
Phase:
Study type: Observational

An observational prospective study to determine the impact of foam sclerotherapy of large, dominant kidney/liver cysts on quality of life outcomes and kidney/liver cyst volumes at up to 12 months of follow-up in patients with autosomal dominant polycystic kidney disease (ADPKD) and autosomal dominant polycystic liver disease (ADPLD).

NCT ID: NCT04079764 Completed - Renal Cyst Clinical Trials

Surveillance of Complex Renal Cysts - the SOCRATIC Pilot Study

SOCRATICp
Start date: September 30, 2019
Phase:
Study type: Observational

One third of individuals aged >60 years will be diagnosed with at least one renal cyst following abdominal imaging. These cystic lesions are categorized according to the Bosniak classification which categorizes cysts according to their degree of complexity and risk of malignancy. Growing evidence suggests that a significant proportion of Bosniak III and IV cysts are benign and that the malignant ones present low metastatic potential. Since renal surgery carries substantial morbidity (20%) and potential mortality (0.5%), active surveillance has gained attention as a potential tradeoff to surgery to overcome overtreatment. Therefore, prospective studies of long-term follow-up are needed to confirm the oncologic outcomes of this strategy for Bosniak III/IV cysts. We first designed a pilot study that will assess the feasibility of a subsequent larger multicenter observational study aiming to ascertain mid-term safety of active surveillance. The objectives of this pilot study are a) Determining patients and urologists buy-in and barriers to the proposed intervention; b) Collecting perceptions and concerns of patients and urologists; c)

NCT ID: NCT04077359 Completed - Clinical trials for Renal Cell Carcinoma

Prospective Trial for Examining Hematuria Using Computed Tomography

PROTEHCT
Start date: September 15, 2019
Phase: N/A
Study type: Interventional

The primary objective is to evaluate whether one-phase nephrographic CT (experimental) is sufficient to detect urothelial cell carcinoma in patients with hematuria compared to the traditional four-phase CT (control).

NCT ID: NCT03900364 Completed - Clinical trials for Carcinoma, Renal Cell

a Prospective Trial Comparing Robot-assisted Partial Nephrectomy Versus Laparoscopic Partial Nephrectomy

Start date: September 3, 2018
Phase: N/A
Study type: Interventional

In this trial the investigators want to examine and compare oncological and surgical outcomes of two surgical techniques in a prospective, randomised, single-blind trial. Therefore the investigators are going to include 30 patients with a renal mass who need surgical treatment. When they fulfill the inclusion criteria they get randomised either for robot-assisted partial nephrectomy or laparoscopic partial nephrectomy. Primary endpoint is the oncological outcome (residual tumor classification, TNM classification), secondary endpoints are operation time, time of ischemia, blood loss, pain after surgery, kidney function, complications and hospital stay.
