Trans-uretero-ureterostomy: British experience.

158 replies to a questionnaire suggest that many British surgeons remain wary of using trans-uretero-ureterostomy, fearing to risk the opposite ureter and kidney or preferring to use a Boari flap or other operation. 141 (27 personal and 114 reported) cases are surveyed. 56 simple Y-anastomoses performed by 27 surgeons gave very good results, with only 4 exceptions due to wrong indications or techniques. Complications were rare. No damage to any opposite ureter or kidney by the procedure was reported. 10 operations enabling a solitary kidney to drain via the opposite spare ureter were all successful. We recommended that during nephrectomy any spare healthy ureter should be preserved so that, if necessary, it can be used to drain the opposite kidney.
