[Retrospective analysis of primary renal sarcoma: 17 cases report].
OBJECTIVE
To investigate the clinical characteristics,prognosis, survival and diagnosis of primary renalsarcoma.


METHODS
In the study,17 cases of renal sarcoma were reviewed and analyzed, the incidence, clinical manifestations, treatments and prognosis of renal sarcoma discussed and analyzed, and the correlated literature also reviewed.


RESULTS
Radical nephrectomy was the main treatment for 16 cases, one case was punctured and pathologized. The distributions of pathology were leiomyosarcoma, malignant fibrous histiocytoma, rhabdomyosarcoma, synoviosarcoma, liposarcoma, and clear-cell sarcoma. Thirteen of the subjects were followed-up, and the time of survival varied from 7 to 132 months.
