High Position of the Third Renal Transplant and Alternative Urinary Tract Reconstruction in a Complicated Case.

ABSTRACT

The decision-making process for treatment of patients with end-stage renal failure, multiple failed renal transplants, and severe comorbidities can be exceedingly difficult due to the inapplicability of many common surgery methods. In this article, we report the treatment of such a patient who underwent a third renal transplant and subsequently developed a ureteral stenosis. The third kidney had been transplanted with a high abdominal position and a partially intra- and retroperitoneally placed ureter due to a bilaterally obtained iliac fossa and severe abdominal adhesions. For the severe ureteric stenosis, an alternative urinary tract reconstruction was developed by making use of the native ureter contralateral to the graft by tunneling under the sigmoid. We recommend this surgical method as a valid alternative for patients with severe ureteric graft stenosis, when treatment with stenting and common surgical ureter reconstruction methods are not feasible.
