Brief Summary
This clinical trial is an open-label, randomized controlled study designed to evaluate the efficacyand safety of salt substitutes in protecting renal function after kidney tumor surgery, aiming toprovide dietary renal protection strategies for postoperative kidney tumor patients. lt will alsoassess the feasibility of salt substitute intervention. The primary research questions are: 1. Does a salt substitute diet significantly improve estimated glomerular filtration rate (eGFR) compared to a regular salt diet in postoperative kidney tumor patients? 2. What is the safety profile of salt substitute intervention in postoperative kidney tumor patients? 3. What is the compliance rate among postoperative kidney tumor patients using saltsubstitutes? 4. ls the salt substitute intervention feasible? Researchers will compare the intervention group (salt substitute diet) with the control group (regular salt diet) to determine whether salt substitutes effectively improve postoperative eGFR in kidney tumor patients. Participants will be required to: 1. Consume salt substitutes or regular salt daily while strictly adhering to WHO-recommendedsalt intake levels for 1 year. 2. Undergo scheduled baseline assessments at 1, 3, 6, and 12 months post-surgery, with 24-hoururine tests at months 1 and 6 to evaluate compliance. 3. Receive regular monitoring of blood electrolytes, eGFR, and other renal function indicators. 4. Document any adverse events or health status changes during the study period.
Eligibility Criteria
Inclusion Criteria: * Participants must meet all of the following criteria: 1. Voluntary participation with signed informed consent from both the primary participant and all cohabiting family members, with commitment to study procedures and follow-up; 2.
