OBJECTIVE
To evaluate the functional prognosis of kidneys affected prenatally by urinomas.
METHODS
This was a retrospective review of cases of fetal urinoma reported in the literature, as well as two of our own cases.
RESULTS
Twenty-three patients with a prenatal diagnosis of urinoma (five bilateral) were included in the analysis. Postnatal ipsilateral renal function was observed in only six of the 28 renal units (i.e. around 20%).
CONCLUSIONS
Although the precise causes of urinomas are still unknown, this review shows that in the event of a fetal urinoma, the probability of a non-functional dysplastic ipsilateral kidney lies at around 80%. In-utero puncture only appears to be justified in cases where fluid accumulation has mass effects on adjacent major structures.
目的
评估产前受尿囊肿影响的肾脏的功能预后。
方法
这是一项对文献报道的胎儿尿囊肿病例以及我们自己的两例病例的回顾性研究。
结果
分析纳入了23例产前诊断为尿囊肿的患者（5例双侧）。28个肾单位中仅有6个（即约20%）在出生后观察到同侧肾功能。
结论
尽管尿囊肿的确切病因仍不清楚，但本综述表明，在胎儿发生尿囊肿的情况下，同侧肾脏发育不良且无功能的概率约为80%。仅在积液对相邻主要结构产生占位效应的情况下，宫内穿刺似乎才是合理的。
