Histology of ureter after unsuccessful endoscopic intubated incision.
Endoscopic intubated ureterotomy is used increasingly for treatment of ureteral stricture. In 3 patients with recurrent stricture after this procedure the area of ureterotomy was excised after 69, 78 and 83 days, and cut in cross section to examine the scar for muscle regeneration. A segmental scar was found consisting of collagen-rich connective tissue with few fibroblasts. Scarce smooth muscle fibers were dispersed within the scar, mostly at the edge of incision but without a regular structure.
