To review our experience with the antenatal detection and subsequent neonatal outcome of fetuses with a pelvic kidney.
A retrospective review of 25,551 obstetric ultrasound examinations performed after 16 weeks' gestation identified 13 cases of fetal pelvic kidneys (one per 1965 examinations).
Three pelvic kidneys were dysplastic; the remainder appeared sonographically normal. Seven pelvic kidneys were measured; five were smaller than expected for gestational age. Associated anomalies were detected in three cases.
Careful second- and third-trimester ultrasound examinations can detect an absence of the kidney in the renal fossa. Evaluating the migratory path of the kidney from the pelvis to the renal fossa will frequently result in detection of an ectopic kidney.
回顾我们对盆腔肾胎儿的产前检测及随后新生儿结局的经验。
对妊娠16周后进行的25551例产科超声检查进行回顾性分析，确定了13例胎儿盆腔肾（每1965次检查中有1例）。
3例盆腔肾发育异常；其余超声检查显示正常。对7例盆腔肾进行了测量；5例小于孕周预期大小。3例检测到相关异常。
孕中期和孕晚期仔细的超声检查可发现肾窝处无肾。评估肾脏从盆腔至肾窝的迁移路径常可发现异位肾。
