Principal characteristics of "aberrant papillae" are described, this curious embryologic anomaly being generally detected from the hematuria provoked. Intravenous urography reveals the presence of a persistent lacuna in a calix or of the pelvis, radiologic evidence of the abnormal papilla. Ultrasound and CT scan imaging provide few supplementary data. The most frequent differential diagnosis is from a pyelocaliceal tumor, the known risk of evolutory changes in the latter explaining why most "aberrant papillae" are treated by nephrectomy or even nephroureterectomy. The use of nephroscopy or ureteroscopy should allow, as in the case reported, these abusive nephrectomies to be avoided in the future.
描述了“迷走乳头”的主要特征，这种奇特的胚胎学异常通常由引发的血尿检测出来。静脉肾盂造影显示肾盏或肾盂存在持续的腔隙，这是异常乳头的放射学证据。超声和CT扫描成像提供的补充数据很少。最常见的鉴别诊断是与肾盂肾盏肿瘤相鉴别，后者已知存在进展性变化的风险，这解释了为什么大多数“迷走乳头”采用肾切除术甚至肾输尿管切除术治疗。正如所报道的病例那样，使用肾镜或输尿管镜检查将来应能避免这些过度的肾切除术。
