Study type | Observational |
The purpose of the study is to evaluate patient-specific surgical simulation by permitting pre-operative rehearsals, in the form of the surgeon completing a dry run of the procedure on a model constructed from the patient's radiological studies that replicates every aspect of their organs. The investigators' aim is to evaluate the effectiveness of this form of practice in optimizing intraoperative and postoperative outcomes . The investigators hope eventually to use these rehearsals as a standard study tool for surgical training.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Warm ischemia time measured during minimal invasive partial nephrectomy surgery | Warm ischemia time is reported on completion of minimal invasive partial nephrectomy surgery, the metric will be measured in minutes as a continuous variable. | At the end of each surgical procedure, approximately 24 hours after surgery | |
Primary | Estimated blood loss measured during minimal invasive partial nephrectomy surgery | Estimated blood loss is reported on completion of minimal invasive partial nephrectomy surgery, it is estimated by the volume of fluid in the suction irrigation at the end of surgery and measured in ml as a continuous variable. | At the end of each surgical procedure, approximately 24 hours after surgery | |
Primary | Change in postoperative renal functions | The difference between preoperative (within a week prior to surgery) and postoperative (12 hours , 1 day and 30 days after surgery) using estimated GFR measured through serum creatinine blood test. | Zero at date of randomization and serial measurements at 12 hours , 1 day and 30 days after surgery | |
Primary | Surgical complications | Intraoperative and postoperative complications will be measured and reported using the modified Clavien-Dindo classification of surgical complications (Grade 1 to 5). | From date of surgery up to 30 days postoperative, every complication encountered during that time will be recorded | |
Primary | Objective evaluation of surgical performance | All surgical cases will be recorded and reviewed by a third party online tool that specializes in evaluation of surgical performance using the GEARS (Global Evaluative Assessment of Robotic Skills) tool | At the end of each surgical procedure, approximately 24 hours after surgery | |
Primary | Operative time measured during minimal invasive partial nephrectomy surgery | Operative time is reported on completion of minimal invasive partial | At the end of each surgical procedure, approximately 24 hours after surgery | |
Secondary | Positive margins of the tumor specimen | On pathological examination the presence or absence (+/-) and length in millimeters (mm) will be measured | From date of randomization up to 10 days after surgery | |
Secondary | Change in the volume of ratio of red blood cells to total blood volume (HCT) | The difference between preoperative (within a week prior to surgery) and postoperative (12 and 24 hours after surgery) using the blood test HCT. | Zero at date of randomization and serial measurements at 12 and 24 hours after surgery | |
Secondary | Hospital stay | The length of hospital stay will be measured from time of admission to day of discharge and will be reported in days | From date of admission up to 30 days after surgery | |
Secondary | Hospital readmission | The readmission rates of patients enrolled in the study will be measured and reported in number of patients | From date of surgery up to 30 days postoperative, every hospital readmission encountered during that time will be recorded |
