胎儿肾积水占所有出生新生儿的0.59%～1.4%,其病因复杂,目前尚无统一的诊断标准。随着各种产前诊断技术的开展,特别是超声诊断技术的广泛应用,肾积水越来越容易作出产前诊断,因此对其进行宫内治疗成为可能。但是,宫内治疗仍然是一个实验性的技术,需要权衡利弊。 Fetal hydronephrosis accounted for 0.59% to 1.4% of all newborns born, its etiology is complex, there is no uniform diagnostic criteria. With the development of various prenatal diagnostic techniques, especially the extensive application of ultrasonic diagnostic techniques, hydronephrosis is more and more easy to make prenatal diagnosis, so it is possible to treat it intrauterineally. However, intrauterine therapy remains an experimental technique that weighs the pros and cons.
