Inclusion criteria

* Age 20 years or more * Histologically or cytologically diagnosed upper tract urothelial cancer * Fitting indications of radical nephroureterectomy and ipsilateral bladder cuff resection, and deemed feasible for robotic surgery * ASA physical status classification 1-2 and adequate organ function * Patients willing and able to comply with study protocol requirements and follow-up * With informed consent

Exclusion criteria

* Synchronous bladder cancer * Distant metastasis of cancer * BMI ≥30 or BMI \<18.5 * Unable to tolerate lateral decubitus or Trendelenburg position (relative contra-indication) * Severe adhesion due to prior abdominopelvic surgery (relative contra-indication) * Previous radiation treatment to the pelvic area * Active infectious disease * Severe concomitant illness that drastically shortens life expectancy or increases risk of therapeutic interventions, such as: severe heart disease (NYHA functional class III-IV) or severe lung disease (GOLD Group C-D) * Cannot follow trial-required procedures * Concomitant systemic or pelvic disease that increases the risk of surgery * Long-term use of anti-coagulant(s) * Patients with coagulopathy * Emergency surgery

Design outcomes

Primary

MeasureTime frameDescription
Incidence of conversion rateDuring SurgeryThe primary performance endpoint will be assessed as the ability to successfully completed the planned procedure with da Vinci SP System, with no conversion to alternative surgery including open surgery or laparoscopy.

Secondary

MeasureTime frameDescription
Perioperative Parameters: Estimated Blood Lossimmediately after the surgeryEstimated blood loss by mL
Postoperative Parameters: Length of Stay30 days post operationTotal length of stay = discharge date - admission date
Perioperative Parameters: Operative Timeimmediately after the surgeryFirst skin incision to closure of wound by minutes.
Perioperative Parameters: Console Timeimmediately after the surgerySurgeon on Console Time by minutes
Perioperative Parameters: Transfusionimmediately after the surgeryBlood transfusion amount by bags
Postoperative Parameters: Readmission30 days post operationReadmission rate by %
Postoperative Parameters: Reoperation30 days post operationReoperation rate by %
Perioperative Mortality30 days post operationMortality by %
Pain Score30 days post operationmeasured by Visual Analogue Scale (VAS) for pain assessment at baseline, post operation, and discharge day. VAS ranged from 0 to 10, representing no pain to extreme pain.
Complication30 days post operationIntraoperative and/or postoperative complication rate in 30 days by Clavien-Dindo Classification
