Kidney Tumor
Conditions
Interventions
Prospective intervention group:Undergo three-dimensional reconstruction of preoperative imaging data (CT/MRI) and automatic ROADS scoring, providing the surgeon with a reference for surgical strategy.
Retrospective control group:The control group consisted of patients who had undergone surgery previously. The surgical approach was determined by the surgeon based solely on two?dimensional imaging, n

Inclusion criteria
Inclusion criteria: Prospective Cohort Inclusion Criteria: 1.Patients with renal hilar tumors (tumors located at the renal hilum with contact with renal vessels) who are scheduled to undergo nephron-sparing surgery at the center. 2.Age between 18 and 75 years. 3.Preoperative evaluation shows clinical stage cT1, or cT2 patients who require nephron-sparing surgery due to solitary kidney, chronic renal failure, or other reasons. 4.Have in-hospital imaging examinations (CT/MRI) obtained during hospitalization or within 3 months before admission at the hospital, which can be used for three-dimensional reconstruction. 5.Voluntarily join the study, sign informed consent, have good compliance, and be willing to cooperate with follow-up. Retrospective Cohort Inclusion Criteria: 1.Patients with renal hilar tumors (tumors located at the renal hilum with contact with renal vessels) who were scheduled to undergo nephron-sparing surgery at the center between 2022 and 2025. 2.Age between 18 and 75 years. 3.Preoperative evaluation shows clinical stage cT1, or cT2 patients who require nephron-sparing surgery due to solitary kidney, chronic renal failure, or other reasons. 4.Have in-hospital imaging examinations (CT/MRI) obtained during hospitalization or within 3 months before surgery at the hospital, which can be used for three-dimensional reconstruction. 5.Complete medical records with full perioperative laboratory results at the hospital.
Exclusion criteria
Exclusion criteria: Prospective Cohort Exclusion Criteria: 1.Prior history of ipsilateral renal surgery. 2.Concurrent malignancy of other systems. 3.Patients with preoperative evidence of renal pelvis/renal sinus invasion, lymph node metastasis, or distant metastasis, as well as those who do not otherwise meet the indications for nephron-sparing surgery. 4.Presence of absolute contraindications to surgery (including bleeding or coagulation disorders, severe cardiopulmonary insufficiency, etc.). 5.Severe uncontrolled diseases (e.g., uncontrolled hypertension, cardiac insufficiency, hepatic or renal insufficiency) or active infections. 6.Patients with cognitive impairment, psychiatric disorders, or poor compliance. Retrospective Cohort Exclusion Criteria: 1.Lack of necessary in-hospital imaging data or perioperative laboratory/ examination data. 2.Patients scheduled for nephron-sparing surgery who voluntarily withdrew and were discharged without undergoing the procedure. 3.Lack of renal function test results (e.g., serum creatinine, glomerular filtration rate) during the 1-year postoperative period.
