Duplicated collecting systems have a predictable draining pattern that is described by the Meyer-Weigert rule. When there are abnormalities associated with duplicating collecting systems, the upper pole moiety drains inferomedially (most commonly associated with obstruction), and the lower pole moiety drains superolaterally (most commonly associated with vesicoureteral reflux). We present a case of an infant with a duplicated collecting system that violates the Meyer-Weigert rule with lower pole megaureter with massive dilation, ectopic insertion, and associated involuted lower pole renal moiety. To our knowledge, this is the only reported case of a lower pole ectopic ureter with an involuted lower pole renal moiety.
重复集合系统具有一种可预测的引流模式，由迈耶 - 魏格特法则描述。当存在与重复集合系统相关的异常时，上极部分向内侧下方引流（最常与梗阻相关），而下极部分向上外侧引流（最常与膀胱输尿管反流相关）。我们报告一例患有重复集合系统的婴儿病例，该病例违反了迈耶 - 魏格特法则，伴有下极巨输尿管，伴有大量扩张、异位插入以及相关的萎缩性下极肾部分。据我们所知，这是唯一一例报道的伴有萎缩性下极肾部分的下极异位输尿管病例。
