The restoration of the continuity of the urinary tract represents one of the major problems in rat renal transplantation. End‐to‐end ureterostomy is the most physiologically effective technique; however, it involves noteworthy technical difficulties because of the extremely thin caliber of the ureter in the rat and the high incidence of postoperative hydronephrosis. We describe a new technique for end‐to‐end ureterostomy in the rat, where the use of an absorbable ureteral stent is recommended. A 5‐0 plain catgut thread is used as a stent. The anastomosis is performed under an operating microscope at × 25–40 magnification with interrupted sutures of 11‐0 Vicryl. The use of the indwelling stent facilitates the performance of the anastomosis and yields optimal results. The macroscopical, radiological, and histological controls in a group of rats operated on with this technique showed a very high percentage of success with no complications, a result undoubtedly superior to that obtained with conventional methods.
