Imaging-Guided Classification for Endophytic Renal Tumors: PN Strategies & Outcomes

Surgical options for completely endogenous renal cancer include laparoscopic, open, and robotic. The impact on the patient is assessed according to the different surgical modalities.

In renal cancer surgery (particularly partial nephrectomy), the Trifecta achievement consists of:

• Negative surgical margins (no residual tumor)
• No perioperative complications (e.g., hemorrhage, urinary leakage)
• Preservation of renal function (minimal decline in eGFR)

The tumor subtypes of renal cancer studied in this study included clear cell carcinoma, papillary carcinoma, and smoky cell carcinoma.

It was used to assess the size of the tumor, and in this study, due to the endogenous nature of the tumor, the tumors were generally small, less than 5 cm

Patient's age at diagnosis

Sex of the patient, categorized as male, female.

Split into left and right side.

Body Mass Index.The formula is: BMI = weight ÷ height squared (weight in kilograms; height in meters)

"0" means current or former smoker, '1' means no smoking. Used to assess whether or not one has smoked. To observe the effect on disease

"0" indicates current or previous alcohol consumption and '1' indicates no alcohol consumption. Used to assess whether or not one has been drinking. To observe the effect on disease.

"0" means having or currently having high blood pressure and '1' means not having high blood pressure. It is used to assess whether or not a person has ever had a hypertensive disorder.To observe the effect on disease

"0" means current or previous diabetes, '1' means no diabetes. Used to assess for a history of diabetes. To observe the effect on disease

0 Fully normal mobility, with no difference in mobility from that before the onset of the disease.

• Able to walk freely and engage in light physical activities, including general housework or office work, but unable to engage in heavier physical activities.
• Able to walk freely and take care of oneself, but with loss of working ability, and can get up and move around not less than half of the time during the day.
• Can only partially take care of oneself, and spends more than half of the day in bed or in a wheelchair.
• Bedridden, unable to take care of themselves.
• Death Higher scores mean worse.

Score 0: Low risk. The patient has no specific co-morbidities included in the CCI score, indicating that the patient is relatively healthy and has a high survival rate.

Score 1-2: Moderate risk. Patients may have one or two milder co-morbidities, but overall risk is relatively low.

Score 3-4: Moderate to high risk. Patients may have a moderate burden of co-morbidities and may have reduced survival.

Score 5-6: High risk. Patients have a high burden of co-morbidities and may require closer monitoring and care.

Score 7 and above: Very high risk. The patient has a more severe burden of co-morbidities and may have significantly reduced survival and a higher risk of treatment.

• Physical health, good development and nutrition, normal function of organs. Perioperative mortality rate 0.06%-0.08%;
• Mild coexisting diseases other than surgical diseases, with sound functional compensation. Perioperative mortality rate 0.27%-0.40%;
• Severe coexisting conditions with limited physical activity, but still able to cope with daily activities. Perioperative mortality rate 1.82%-4.30%;
• Severe coexisting conditions with loss of ability to perform daily activities and frequent life threatening situations. Perioperative mortality rate 7.80%-23.0%;
• Dying patients who have difficulty sustaining life for 24 hours regardless of surgery. Perioperative mortality rate 9.40%-50.7%;
• Confirmed brain death with organs intended for organ transplantation.

The scores are 0, 1, 2, 3 and 4, ranging from "none" to "very serious", respectively.

The R.E.N.A.L. scoring system is based on the anatomical features of renal tumors, including tumor size (R), convexity (E), relationship to the renal sinus and collecting system (N), ventral or dorsal renal location (A), location along the longitudinal axis of the kidney (L), and relationship to the renal hilum (h), and quantitatively evaluates each aspect based on the scores.

Higher scores mean worse.

The time it takes the doctor to make the cut and the time it takes to close the incision.

By intraoperative blood loss, we actually mean loss of circulating blood volume

The length of time between blocking the blood supply to the kidneys, the state of persistent ischemia at room temperature, and the restoration of the blood supply.

Length of hospitalization of patients after surgery
