Renal transplantation from a living related donor with a retrocaval ureter--a note of caution.
In our study we describe a renal transplant from a living related donor who was found to have a retrocaval ureter. The retrocaval ureter is a rare congenital anomaly resulting from a defect in the embryological development of the ureter and the inferior vena cava (IVC). The compression of the ureter between the IVC and the vertebrae can result in progressive hydronephrosis. The non-dilated segment of the ureter was used for the uretero-neocystostomy. The patient presented with ureteric obstruction in the immediate post-transplant period, and at surgical exploration the ureteroneocystostomy was revised using the dilated portion of the ureter. We recommend that when transplanting a kidney with a retrocaval ureter, caution should be exercised in using the non-dilated portion of the ureter, since either the blood supply may be compromised or the peristalsis may be interrupted.
