[Transjejunal subpyelic cutaneous ureterostomy. A solution to upper urinary diversion in pelvic oncology].

In the operation described the second jejunal loop is isolated through an horizontal incision linking the tips of the 12 th ribs. The ends of the loop are then anastomosed with the sub-pyelic ureters and the resulting V-shaped conduit is brought to the skin. The main complication is a salt-deficiency syndrome due to the physiology of the isolated jejunal loop. The loss of salt may be troublesome in patients with pre-existing renal insufficiency. This syndrome is corrected by oral administration of sodium chloride.
