The occult ureter in a duplex kidney should be recognized during the procedure time even if the intravesical orifice has not been visualized. In the opposite case it is possible to do some therapeutic errors. That is the reason why the authors report four new cases with five occult ureters in a duplex kidney. One is diagnosed during a second procedure for removing a stenosis on an unfortunate reimplantation with an acute renal failure. Four occult ureters were found during an intervention for a vesicorenal reflux on the functional ureter. The upper pouch was blind without any renal parenchyma in three cases and in two cases there was a little renal dysplasic parenchyma. In the four ureters where we have been able to observe the down pouch we have not seen an orifice in three cases and in one case the orifice was in ectopic position. Commentaries are done about the clinic context the similarities between this unrecognised ureter and ureterocele. Therapeutic approach is precised with the interest of an opacification during the procedure of all supplementary conduct discovered while the dissection of an ureter.
在手术过程中，即使未观察到膀胱内开口，也应识别重复肾中的隐匿性输尿管。反之，则可能会出现一些治疗失误。这就是作者报告4例新病例，共5条重复肾隐匿性输尿管的原因。其中1例是在第二次手术中诊断出来的，该手术是为了修复一次不幸的再植手术中的狭窄并伴有急性肾衰竭。在对功能性输尿管进行膀胱输尿管反流干预时发现了4条隐匿性输尿管。3例患者的上半肾囊为盲端，无任何肾实质，2例患者有少量肾发育不良的实质。在我们能够观察到下半肾囊的4条输尿管中，3例未发现开口，1例开口位于异位。文中对临床背景、这种未被识别的输尿管与输尿管囊肿之间的相似性进行了评论。明确了治疗方法，即在输尿管解剖过程中，对所有发现的辅助管道进行造影具有重要意义。
