For many patients with hydronephrosis, fetal patients for various reasons, the proportion of sick is increasing year by year. For the relatively fragile fetal patients, after suffering from this disease, will give a great impact on growth. So, what is the prevention of fetal hydronephrosis?
It should be noted that the normal fetal kidney collection system generally have mild separation, the specific separation diameter of up to 6 mm, and gestational age greater than 30 weeks after the expansion of the renal pelvis ≥ 10 mm, or the presence of renal dilatation was hydronephrosis , So when the situation is found, it is necessary to check, once the diagnosis please timely treatment.
Usually patients with hydronephrosis can be pided into two kinds, one is not reducible, one is reducible, different situations, different specific criteria, such as irreducible water width: 2.15 - 2.56 cm, renal parenchyma thickness of 0.3 - 0.2 cm, common in congenital ureteral stricture, multi changes in secretory function.
The patient can be refurbished hydronephrosis: the specific water width is generally between 1.01-1.63 cm, and the renal parenchyma thick, mostly between 1.02-0.58 cm, after the birth of the baby changes in the environment, at this point the water disappeared. Common in the fetus of the bladder a lot of urine filling or some cause of ureteral contraction rhythm disorders. In addition, some cases of ureter may be some abnormal anatomical structure.
In general, the prevention of fetal hydronephrosis, regular examination is very important, and if it is found in the case of fetal hydronephrosis, do not worry too much, do not rush to terminate the pregnancy, the best is B Ultrasound found after hours or weeks. Such as the width of fetal hydronephrosis <1.63 or> 0.58 cm, can be regarded as normal; such as water width> 2.15 cm or renal parenchyma thickness <0.2 cm is irreducible, according to the actual situation to choose whether to terminate the pregnancy.
