Hitherto experimental surgery has not supplied the practitioner with a method by which the continuity of the ureter, when completely divided by transverse injury, could be restored. The brilliant case reported recently in full by Kuester, in which the upper end of the ureter—the infundibuliform portion—was excised to relieve obstruction, has been exceeded in ingenuity of conception by the work of Prof. Christian Fenger, in two cases reported at the meeting of the Chicago Medical Society held February 6, 1893. But these cases offer no suggestions to aid in the effort to unite the ends of the transversely divided ureter when that injury occurs below the infundibulum. The experiments of Th. Tuffier, who endeavored to accomplish this object by the application of sutures, are discouraging in the extreme. For even when union took place, the resulting scar contraction of course obliterated the lumen of the duct.
