Treatment of benign renal tumors in men is mainly surgical. Asymptomatic cases can be followed up regularly without treatment. Common benign tumors of kidney include: malignant tumors, renal vascular smooth muscle lipoma and so on.
1. Renal malformation tumor: malformation tumor less than 4cm can be left untreated; malformation tumor with large size is feasible for enucleation or partial nephrectomy; if the tumor is large, the renal structure is destroyed, and the function is completely lost, nephrectomy can be considered.
2. Renal vascular smooth muscle lipoma: small tumors can be followed up for a long time without treatment; if the tumor is large and tends to grow or accompanied by pain, partial nephrectomy or simple resection of the tumor by selective angiography is feasible; more renal tissues should be preserved as much as possible during the surgery for both sides of renal tumors.
If the diagnosis of tumor is made, regular follow-up review should be conducted to avoid malignant transformation of the tumor.
