# Renal Transplantation in Patients With Urinary Diversion—Bypassing the Conduit: A Case Report

## TL;DR

This case report describes a successful alternative method for kidney transplantation in patients with urinary diversions by connecting the donor and recipient ureters.

## Contribution

The paper presents two recent successful cases using uretero-uretero anastomosis in renal transplantation.

## Key findings

- Two patients with prior ileal conduits underwent successful renal transplantation using uretero-uretero anastomoses.
- Uretero-uretero anastomosis can be a viable alternative when ureteroileal anastomosis is challenging.
- This technique has been rarely reported in the last 20 years.

## Abstract

Kidney transplantation in patients with supravesical urinary diversions is a relatively rare procedure. The typical approach for establishing urinary drainage in these patients is through an ureteroileal anastomosis. However, a tension-free ureteroileal anastomosis can be difficult to achieve based on variations in the anatomy of the donor ureter or recipient conduit. An alternative technique can be to create an anastomosis between the donor and recipient ureter, although reports of this technique in the last 20 years have been sparse. Here, we present two cases of patients with prior ileal conduits who underwent successful renal transplantation with uretero-uretero anastomoses.
