RESUMEN
Objective To discuss the treatment of synchronous bilateral renal cell carcinoma.Methods Fourteen cases of synchronous bilateral renal cell carcinoma with 12 males and 2 females were treated from 1994 to 2005.Lumbago occurred in 4 cases and hematuria in 2 cases.All the cases were diagnosed with the CT scan,IVU,US and/or MR.Six cases received bilateral operation simultaneously,8 cases received sequential operations.Radical nephrectomy on one side and partial nephrectomy on the opposite side was conducted in 8 patients.Partial nephrectomy on both sides was performed for 6 patients. Results Twenty-two operations were performed in 14 cases.The average operative time was(263±52)min in simultaneous operation and(155±46)min in others.The length of hospital stay was(11.5±2.1)d in simultaneous operation and(7.4±1.2)d in staging operatiom Ten cases were followed up for 6-41 months.The renal function remained good in 7 patients.The SCr increased in 3 cases with no need for dialysis.One case died 25 months later with metastasis of lung.One case with local recurrence died 38 months later.One case died of cerebral hemorrhage.Conclusions The renal function and treating tumor must be considered in managing synchronous bilateral renal cell carcinoma.The geheral condition of patient and the position of tumor should be evaluated in order to make a treatment plan.
