How should a 0.9 cm small nodule in the left kidney be treated?

In general, if a small nodule measuring 0.9 cm is found in the left kidney and does not cause any adverse symptoms, conservative management may be adopted. However, if other complications or symptoms are present, treatments such as medication, physical therapy, or surgical intervention may be required. The specific treatment approaches are analyzed as follows:

1. Conservative Management

If the nodule is relatively small and not causing any adverse reactions, patients can opt for regular monitoring and follow-up examinations, with conservative management being appropriate.

2. Medication

If the presence of the small nodule leads to symptoms such as kidney pain or swelling, patients may, under medical guidance, use medications such as ibuprofen capsules, diclofenac sodium sustained-release tablets, or indomethacin capsules.

3. Physical Therapy

Extracorporeal shock wave lithotripsy (ESWL) is a common treatment method for small nodules. This approach uses external shock waves to break the nodule in the left kidney into fine powder, which is then naturally expelled from the body through urine, thereby improving the condition.

4. Surgical Treatment

If a 0.9 cm nodule exerts pressure on surrounding soft tissues, it may cause localized pain. As the nodule increases in size, it may disrupt the normal structure and function of the kidney and could be accompanied by symptoms such as fever or hematuria. In such cases, patients should seek treatment at a qualified medical facility, where surgical removal of the left renal nodule may be performed.

In addition to the above treatment options, patients should also strengthen dietary management during recovery. They should moderately increase fluid intake, maintain a light and easily digestible diet, and avoid spicy and irritating foods such as chili peppers and ginger. Maintaining healthy eating habits can help promote recovery.
