case_images: Repeated ultrasound evaluations confirmed intrauterine growth restriction in twin 1 by 24.7 % and twin 2 by 14.3%, respectively, and polyhydramnios as the cause of imminent preterm labour (Figure 1A). Because of the well-known association between polyhydramnios and elevated uraemic toxins, intrauterine growth restriction and threatening preterm labour of premature children, haemodialysis treatments were started to reduce uraemic toxins, including blood urea nitrogen (Figure 1B). Birth weights of the twins were 941 and 1164 g, respectively (Figure 1C).
