RESUMEN
OBJECTIVE: To evaluate the clinical and pathological characteristics of cystic renal tumors in our center. MATERIAL AND METHODS: A retrospective review of 239 nephrectomies is performed comparing the clinical and pathological variables of cystic tumors with those of solid renal tumors. Survival outcomes are analyzed in both groups. RESULTS: Our experience shows that cystic renal tumors behave like solid renal tumors, with no differences in survival shown. The variables studied show statistically significant differences in histological grade and number of tumors, with cystic tumors having a lower histological grade and being more often multiple in number. CONCLUSIONS: The behavior of cystic renal tumors is no different than that of solid renal tumors.
