Reemplazo ureteral con apéndice cecal / Ureteral replacement with cecal appendix

ABSTRACT

We report two cases with ureteral lesions. A 34 years male with a residual retroperitoneal mass caused by a testicular cancer, that persisted after chemotherapy. During the surgical excision of the mass, the involvement of the right ureter was discovered. A 43 years old female with a left ureteral lesion secondary to radiation therapy and with a non-functioning contralateral kidney. In both cases a ureteral replacement with the cecal appendix was performed, without surgical complications. After five years of follow up, the urinary tract of the male patient is normal. The female patient required an endoscopic incision of the connection between the appendix and the urinary bladder, eight years after the surgical procedure. Three years after the endoscopic procedure the repaired urinary tract is in good conditions.

RESUMEN

Objetivo: Presentar dos casos de reemplazo ureteral con apéndice cecal y revisar la literatura relacionada al tema. Material y Método: Presentamos dos casos de lesión ureteral. Un paciente de 34 años con masa retroperitoneal residual post quimioterapia englobando el uréter derecho, secundaria a un tumor testicular, y una paciente de 43 años monorrena funcional con lesión ureteral izquierda actínica. Resultados: En ambos casos se realizó un reemplazo ureteral, derecho e izquierdo, sin complicaciones intraoperatorias. El seguimiento alejado a 5 y 11 años muestra indemnidad de la vía urinaria. Conclusión: Estos 2 casos, con seguimiento prolongado, apoyan la factibilidad del uso del apéndice cecal como variante para el reemplazo ureteral en lesiones extensas.
