The results of two animal studies are presented in which ureteroneocystostomy is performed in the absence of urinary flow. No stents were used. In Group 1 ureterovesical stenosis resulted in 2/7 defunctionalized ureters in animals with an otherwise intact bladder. In Group 2 seven animals had bilateral urinary diversion with reimplantation of 14 diverted ureters into a defunctionalized bladder. Ureterovesical stenosis did not occur in any in this second group. There was a 9.5 per cent incidence of ureterovesical stenosis over-all. This would not support the clinical impression that "dry" ureteroneocystostomy inevitably results in ureterovesical stenosis.
本文展示了两项动物研究的结果，这些研究在无尿流情况下进行输尿管膀胱吻合术，未使用支架。在第1组中，输尿管膀胱狭窄导致7只动物中有2只输尿管功能丧失，而膀胱其他部分完好。在第2组中，7只动物进行了双侧尿流改道，并将14条改道的输尿管重新植入功能丧失的膀胱。该组中无一例发生输尿管膀胱狭窄。总体输尿管膀胱狭窄发生率为9.5%。这并不支持“无尿”输尿管膀胱吻合术必然导致输尿管膀胱狭窄的临床印象。
