“…Overall, the results of our study are consistent with the results of the existing literature identifying MRA grafts as those with a good long-term outcome with modestly increased complication rates and thus recommends them for transplant consideration [ 6 , 8 , 9 , 14 , 22 ]. When it comes to the question whether ARA ligation causes a higher complication rate, no statistical significance was found, but the rate of reoperations was slightly higher in the group with ligated vessels due to unspecific reasons.…”

Purpose Accurate surgical reconstruction of arterial vascular supply is a crucial part of living kidney transplantation (LDKT). The presence of multiple renal arteries (MRA) in grafts can be challenging. In the present study, we investigated the impact of ligation versus anastomosis of small accessory graft arteries on the perioperative outcome. Methods Clinical and radiological outcomes of 51 patients with MRA out of a total of 308 patients who underwent LDKT with MRA between 2011 and 2020 were stratified in two groups and analyzed. In group 1 (20 patients), ligation of accessory arteries (ARAs) and group 2 (31 patients) anastomosis of ARAs was performed. Results Significant differences were observed in the anastomosis-, surgery-, and warm ischemia time (WIT) in favor of group 1. Students t-test showed comparable serum creatinine levels of 2.33 (± 1.75) to 1.68 (± 0.83) mg/dL in group 1 and 2.63 (± 2.47) to 1.50 (± 0.41) mg/dL in group 2, were seen from 1 week to 1 year after transplant. No increased rates of Delayed graft function (DGF), primary transplant dysfunction and transplant rejection were seen, but graft loss and revision rates were slightly higher when the ARAs were ligated. Analysis of Doppler sonography revealed that segmental perfusion deficits tend to regenerate during the clinical course. Conclusion Ligation of smaller accessory renal arteries may not affect the outcome of living kidney transplantation, except for a minor increase in the reoperation rate. Segmental perfusion deficits of the graft seem to regenerate in most cases as seen in Doppler sonography.

“…With the development of surgical expertise and minimally invasive techniques, as well as general organ scarcity, LDKT with MRA has become increasingly common in recent years [ 14 ]. The literature describes that MRA kidney transplantation may be associated with higher complication rates and DGF [ 7 ].…”

Introducción. El trasplante es la mejor opción de tratamiento para los pacientes con enfermedad renal terminal, sin embargo, existe discrepancia entre las listas de espera y la disponibilidad de órganos a partir de la donación cadavérica. Buscando aumentar el número de órganos disponibles se implementó el trasplante con donante vivo. A partir de la introducción de técnicas mínimamente invasivas para la nefrectomía, el donante vivo ha logrado cifras cercanas al 50 % de los trasplantes realizados en muchas instituciones, debido a los beneficios propios del procedimiento. El objetivo de este estudio fue describir los resultados después de la incorporación del procedimiento totalmente laparoscópico en nuestra institución. Métodos. Se hizo un análisis retrospectivo de las características de los pacientes llevados a nefrectomía para obtención de injerto por técnica totalmente laparoscópica y los resultados en un solo centro en Cali, Colombia, desde noviembre de 2019 hasta octubre de 2022. Los datos fueron obtenidos mediante la revisión de las historias clínicas electrónicas. Resultados. Se realizaron 78 nefrectomías para obtención de injerto con técnica totalmente laparoscópica. El tiempo operatorio promedio fue de 152 minutos, el sangrado promedio fue de 12 ml, la estancia hospitalaria promedio del donante fue de 2,8 días. La tasa de complicaciones fue de 7,6 % (4 pacientes con complicación Clavien-Dindo I y 2 pacientes Clavien-Dindo IIIb). No se presentó ningún caso de mortalidad. Conclusiones. La técnica totalmente laparoscópica resulta ser una técnica segura con baja tasa de morbilidad y excelentes beneficios para los donantes.
