Inclusion criteria
Inclusion criteria: 1. Age >= 18 years; 2. Undergoing minimally invasive renal surgery at a participating center, including partial nephrectomy, radical nephrectomy, radical nephroureterectomy, inferior vena cava tumor thrombus/cancer thrombus thrombectomy, pyeloplasty, or other related procedures; 3. Availability of intraoperative video recordings suitable for research, with video quality generally sufficient for anatomical identification; 4. Relatively complete perioperative clinical data, sufficient to support the recording of baseline case characteristics and study outcomes; 5. For the prospective validation phase: cases must meet the requirements for consecutive enrollment and comply with the ethical requirements of each participating center regarding informed consent or waiver of informed consent.
Exclusion criteria
Exclusion criteria: 1. Emergency or critically ill cases requiring immediate surgery and deemed unsuitable for inclusion in the study workflow; 2. Video recordings or medical records that cannot be effectively de-identified; 3. Severe video incompleteness, missing key surgical phases, or excessively low resolution that precludes valid analysis; 4. Explicit refusal during the study period to allow the use of their data for research purposes; 5. Other conditions that, in the investigator’s judgment, make the case unsuitable for inclusion in the study.
