An experimental study in dogs showed that the implantation of hydroureters onto a denuded area of the bladder muscle led to mucosal regeneration and formation of a submucosal tunnel. Reflux was prevented in all animals when the bladder wall was immobilized at the reimplantation site by fixation to the psoas muscle. Urinary stasis normalized after 10 to 12 reimplantations. Internal ureteropexy would seem to be a most simple and satisfactory technique for preventing reflux when dissection of a submucosal tunnel fails in ureteroneocystostomy. It has been used in three patients with good results.
在狗身上进行的一项实验研究表明，将积水输尿管植入膀胱肌肉的裸露区域会导致黏膜再生和黏膜下隧道的形成。当通过固定于腰大肌将膀胱壁在再植部位固定时，所有动物的反流均得到预防。在进行10至12次再植后，尿潴留恢复正常。当输尿管膀胱吻合术中黏膜下隧道解剖失败时，输尿管内固定术似乎是预防反流的一种最简单且令人满意的技术。它已应用于3例患者，效果良好。
