    • Abstract:
      Background: Kidney transplant is the best replacement therapy for kidney function in renal disease; the surgical technique is currently standardized; however, unexpected situations may happen during the surgical event that may require modification to it. Right nephrectomies from living donors are technically challenging due to a shorter and thinner vein than the contralateral kidney, with a higher incidence of thrombosis in the recipient. Objective: We analyzed the implementation of the use of polytetrafluoroethylene (PTFE) graft in selected cases for venous reconstruction in kidney transplant in our center. Method: An analysis was carried out from January 2018 to March 2023, with the number of living donor kidney transplants (LDKTs) and the laterality of the nephrectomy, as well as the number of patients who required reconstruction with a PTFE graft. Results: From 2018 to 2023, a total of 389 LDKTs were reported, with 12% of right kidney nephrectomies (n = 46). The number of recipients who required venous reconstruction with PTFE was 3 (6.5% of the living donor right nephrectomies). Conclusion: The use of synthetic vascular grafts is feasible, with an accurate and meticulous surgical technique, combined with the use of prophylactic antiplatelet aggregation, monitoring of the recipient's renal function.

    • Abstract:
      Antecedentes: El trasplante renal es la mejor terapia sustitutiva de la función renal en enfermedad renal crónica. La técnica quirúrgica está estandarizada, sin embargo pueden ocurrir situaciones inesperadas durante el evento quirúrgico que requieran su modificación. Las nefrectomías derechas de donador vivo son técnicamente desafiantes, debido a una vena más corta y delgada que el riñón contralateral, con mayor incidencia de trombosis en el receptor. Objetivo: Analizamos la implementación del uso del injerto de politetrafluoroetileno (PTFE) en casos seleccionados para la reconstrucción venosa en el trasplante renal en nuestro centro. Método: Se realizó un análisis de enero de 2018 a marzo de 2023, con el número de trasplantes renales de donador vivo y la lateralidad de la nefrectomía, así como el número de pacientes que requirieron reconstrucción con injerto de PTFE. Resultados: En el periodo 2018-2023 se reportaron 389 trasplantes renales de donador vivo, con un 12% de nefrectomías de riñón derecho (n = 46). El número de receptores que requirieron reconstrucción venosa con PTFE fue 3 (6.5% de las nefrectomías derechas de donante vivo). Conclusión: El uso de injertos vasculares sintéticos es factible, con una técnica quirúrgica precisa y minuciosa, además del uso de antiagregación plaquetaria profiláctica, monitoreo de la función renal del receptor.
