Appendicocecal Loop Urinary Diversion in a Transplant Kidney: Case Report, Literature Review

Urinary diversion in renal transplant patients can take a variety of forms - bladder augmentation, continent cutaneous pouch, or intestinal conduits, to name a few. Herein, we present a unique case of an appendicocecal urinary diversion in a patient with history of end stage renal disease, pelvic radiation, and complex surgical history who underwent deceased-donor renal transplantation. During the renal transplant, the transplant ureterovesical anastomosis could not be performed due to inherent anatomical hindrances. A temporary modified cutaneous ureterostomy using a single-J stent was therefore used for drainage of the transplant kidney. Given that the cutaneous ureterostomy was not a durable, long-term option, we sought to develop a creative surgical solution. This report presents a unique case of urinary diversion post renal transplant and reviews the literature of renal transplantation in patients with anatomical abnormalities.
