Relevancia:  El carcinoma renal representa el 2-3 % de los cánceres urológicos primarios, mientras que el carcinoma urotelial del tracto superior es un tumor uroepitelial raro cuya incidencia alcanza el 5 al 10 % de todos los carcinomas uroteliales. Si bien es raro que los tumores urológicos ocurran juntos, es aún más raro encontrar un carcinoma renal combinado con carcinoma urotelial de tracto superior; se estima que se presenta en 1.1 % de los casos.  Implicaciones Clínicas:  Para el tratamiento del cáncer renal combinado con cáncer urotelial de tracto superior, la nefroureterectomía radical con nefrectomía parcial contralateral sigue siendo la mejor opción de tratamiento mostrando buenos resultados oncológicos.  Conclusiones:  La incidencia de los tumores sincrónicos aumenta simultáneamente con el aumento de la incidencia de tumores genitourinarios. El tratamiento implica un reto para el urólogo y debe ser individualizado de acuerdo a las características del paciente.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  Clinical case presentation:  A 71-year-old male patient presented with anemic syndrome and macroscopic hematuria. Utrotomography showed left renal cancer and urothelial tumor of the right upper urinary tract of synchronous appearance; Nephroureterectomy with bladder cuff on the right side and partial left nephrectomy were performed, both laparoscopically at the same surgical time.  Relevance:  Renal carcinoma represents 2-3 % of primary urological cancers, while upper tract urothelial carcinoma is a rare uroepithelial tumor whose incidence reaches 5-10 % of all urothelial carcinomas. While it is rare for urologic tumors to occur together, it is even rarer to find renal carcinoma combined with upper tract urothelial carcinoma; It is estimated that it occurs in 1.1 % of cases.  Clinical implications:  For the treatment of renal cancer combined with upper tract urothelial cancer, radical nephroureterectomy with contralateral partial nephrectomy remains the best treatment option showing good oncological results.  Conclusions:  The incidence of synchronous tumors increases simultaneously with the increase in the incidence of genitourinary tumors. Treatment represents a challenge for the urologist and must be individualized according to the patient's characteristics.]]></p></abstract>
