Synchronous bilateral renal tumour: a case report

We report a case of synchronous bilateral renal carcinoma treated by partial nephrectomy on the right and total nephrectomy on the left. Follow-up at 42 months after surgery showed no recurrence of the disease. The increasing use of diagnostic imaging techniques such as ultrasound tomography, computerised tomography and nuclear magnetic resonance now allows even small-sized renal formations to be identified. Synchronous bilateral renal tumour has a favourable prognosis, especially when compared with single or asynchronous renal tumours. The recommended intervention is total monolateral nephrectomy combined with partial nephrectomy. The treatment of neoplasms at a more advanced stage, of such a nature as to necessitate bilateral nephrectomy or chemotherapy, results in a significant increase in mortality. Recently, biological therapy has been proposed as a more promising short-term option using interferon-alpha (IFN-alpha) and gamma.
