Ureterocutaneous anastomosis. II. A new urine collection apparatus to prevent stricture.

The advantages of diversion of the urinary stream by cutaneous ureterostomy in certain selected cases are well established.1 Unfortunately the predisposition toward stricture at the cutaneous anastomosis has necessitated indwelling catheters in most cases.2 A number of ingenious surgical techniques have been devised35 to prevent this complication, some of which are very successful. The attendant problems of infection, hemorrhage, or calculus formation due to an inlying catheter are thus overcome. However, despite the excellent surgical techniques of tubeflap6 and "loop" ureterostomies,7 long-term maintenance of an adequate stoma usually requires frequent dilatation or eventual resumption of an indwelling catheter for satisfactory urinary drainage. 8
