Ectopic (pelvic) kidney is the most common congenital renal anomaly with an incidence of 1 in 500 to 1 in 2000. A pelvic kidney can be encountered at pelvic or paraaortic lymphadenectomy.
In two patients undergoing pelvic lymphadenectomy, lobulated tumors near the pelvic brim were initially interpreted as bulky lymph node conglomerates. Further dissection showed the ureter to originate from the masses, leading to a diagnosis of pelvic kidney.
Pelvic kidneys mistaken for bulky lymph nodes are a potential intraoperative pitfall in patients with gynecologic malignancies. Keys to recognition include an index of suspicion, identifying the course of the ureter and origin of the renal vessels, and confirming absence of a kidney at the normal location.
异位（盆腔）肾是最常见的先天性肾脏异常，发病率为500分之一至2000分之一。盆腔肾可在盆腔或腹主动脉旁淋巴结清扫术中发现。
在两名接受盆腔淋巴结清扫术的患者中，盆腔边缘附近的分叶状肿瘤最初被认为是肿大的淋巴结团块。进一步解剖显示输尿管起源于肿块，从而诊断为盆腔肾。
被误认为肿大淋巴结的盆腔肾是妇科恶性肿瘤患者术中潜在的陷阱。识别要点包括怀疑指数、确定输尿管走行和肾血管起源，以及确认正常位置无肾脏。
