    Abstract:
    OBJECTIVE: To present our experience with synchronous bilateral renal adenocarcinoma. The indications for conservative surgery, the different types and the controversies are discussed. METHODS: 5 patients with bilateral renal adenocarcinoma from our series of 320 renal adenocarcinomas were analyzed for gender, age at presentation, tumor location, size, presenting features and type of surgery performed. RESULTS: Bilateral renal adenocarcinoma accounted for 1.56% in our series. Mean age at presentation was 57.8 years (range 43-69 years). All 5 patients were male. All patients underwent conservative surgery by tumor excision or partial nephrectomy of the side with less involvement followed by delayed radical surgery of the contralateral side. Follow-up ranged from 19 months to 14 years. To date all patients are disease-free and only one is on dialysis 14 years postoperatively. CONCLUSIONS: Bilateral renal adenocarcinoma has been reported to account for 1.4%-5% of all renal masses. The incidence in our series was 1.56%. Conservative renal surgery is indicated in patients like those described herein to prevent the need for dialysis. In our view, conservative renal surgery is a good therapeutic option that carries a small risk of tumor multicentricity and future recurrence.
