Kidney cysts smaller than 3 cm in diameter and asymptomatic usually do not require treatment and can be monitored regularly. For larger or symptomatic cysts, treatment options include medication, aspiration, or surgery, depending on the specific circumstances.
Whether a kidney cyst requires treatment depends primarily on its size, symptoms, and impact on kidney function. 1. If the cyst is less than 3 cm in diameter and asymptomatic, no special treatment is generally needed; regular ultrasound or CT scans to monitor changes are sufficient. 2. When the cyst exceeds 5 cm in diameter or causes symptoms such as lower back pain or hematuria, treatment should be considered. Drug treatment commonly uses diuretics or traditional Chinese medicine. Aspiration is suitable for single, larger cysts, while surgical removal is suitable for multiple cysts or suspected malignant lesions. 3. Daily care is also important, such as controlling protein intake, maintaining adequate hydration, and avoiding strenuous exercise, which helps slow cyst growth and protect kidney function. Patients with familial polycystic kidney disease, even with small cysts, require regular follow-up as they may cause cumulative damage to kidney function. In addition to the above treatments, quitting smoking and limiting alcohol consumption, and preventing urinary tract infections also help maintain kidney health. If a kidney cyst is detected, it is recommended to seek medical evaluation promptly and follow the doctor's advice for appropriate observation or treatment.
