Abstract

Fourteen cases of fetal urethral obstruction were reviewed retrospectively. The purpose of this study was to emphasize the following: 1) prenatal sonographic findings: 2) clinical outcome: and 3) associated congenital anomalies. Decreased amniotic fluid volume complicated 12 pregnancies (86%). A dilated posterior urethra was identified in nine fetuses (64%) and an enlarged bladder in 13 (93%). Evaluation of the fetal kidneys revealed hydronephrosis in 81%, increased parenchymal echogenicity in 73% and macroscopic renal cysts in 15%. There were seven live births, but only two neonates survived beyond 5 weeks. Pulmonary hypoplasia contributed to the five postnatal deaths. Associated congenital anomalies were noted at autopsy in six cases.

摘要

对14例胎儿尿道梗阻病例进行了回顾性研究。本研究的目的是强调以下几点:1)产前超声检查结果;2)临床结局;3)相关先天性异常。羊水过少使12例妊娠(86%)情况复杂化。9例胎儿(64%)发现后尿道扩张,13例(93%)发现膀胱增大。对胎儿肾脏的评估显示,81%有肾积水,73%实质回声增强,15%有肉眼可见的肾囊肿。有7例活产,但只有2例新生儿存活超过5周。肺发育不全导致了5例产后死亡。尸检发现6例有相关先天性异常。
