Brief summary

Laparoscopy, now virtually completely, was replaced with robotic surgery in uro-oncological surgery in the world. And given the significant increase in the number of robotic surgeries for prostate, bladder and kidney cancer, it is now a major domain in oncological surgery. Microport MedBot Inc. has independently developed a domestic surgical robot in China. Therefore, the purpose of the study is to evaluate the safety and efficacy of the Chinese robot when applied to surgery in oncology.

Inclusion criteria

* be aged between 18 years and 80 years; * laparoscopic surgery is required with one of the following surgical indications:(1)planning to perform radical prostatectomy(clinical stage is T1 or T2,and PSA≥ 0.2ng/mL) ;(2) planning to perform nephrectomy * being able to cooperate and complete the follow-up and related examinations; * volunteer to participate in this study and sign the informed consent.

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
surgical success rate24 hours following the surgerySurgery is completed without conversion to other operations and without a re-operation caused by intraoperative complications within 24 hours

Secondary

MeasureTime frameDescription
operative timeduring the surgeryThe starting point and end point of the operation time are the first effective movement of the robot arm and the movement stop of the robot arm after the operation.
length of hospital stay24 hours after dischargeThe total hospital days of subjects from the day of the operation to discharge.
perioperative complication rate2 weeks after operationThe overall incidence of intraoperative and postoperative complications.
The physiological load of the surgeon during the surgeryimmediately after the surgeryThe physiological load is assessed by the LED scale immediately after the surgery. LED is the local experienced discomfort scale used to assess the intraoperative physiological load of different parts of the surgeon's body. There are 10 points in the scale, and higher score means worse, with 0 means no discomfort and 10 is the worst discomfort.
blood lossduring the surgeryAmount of intraoperative bleeding in the patient from the start to the end of the operation
the critical failure rate of the robotic systemduring the surgeryCritical failures that are difficult to repair in a short period of time during robot-assisted surgery and can have a serious impact on the process or the operation
the recoverable malfunction rate of the robotic systemduring the surgeryRecoverable malfunction meant minor errors that could be easily resolved by the technician and has no significant impact on the process or the operation
Instrument performanceimmediately after the surgeryThe researcher fills in the instrument performance evaluation form after the operation to review the performance of the instrument during the test.
The psychological load of the surgeon during the surgeryimmediately after the surgeryThe psychological load is assessed by the SME scale immediately after the operation. SME scale is the subjective mental effort scale used to assess the intraoperative psychological load of the surgeon. The scale has a total of 150 points, with a scale of 10 points. The higher the score, the worse it is, with 0 means no any difficult and above 110 points means extremely difficult.
