Abstract
We present herein the ultrasonographic follow-up of renal ectasia in a male twin fetus.
Clinical case
A 29-year-old woman with a history of 3 pregnancies, one normal delivery, and one cesarean section, had first trimester ultrasound screening at the Center for Opportune Screening of the Instituto de Salud Pública del Estado de Guanajuato (ISAPEG) that revealed a dichorionic diamniotic twin pregnancy with negative screening test results.
At 20.1 weeks of gestation, a structural ultrasound detected left renal ectasia in one of the twins. The 2010 Antenatal Hydronephrosis Grading Classification of the Society of Fetal Urology was used to measure and classify the ectasia of the left renal pelvis.
The ultrasonographic follow-up of the left renal pelvis in the twin detected with hydronephrosis according to the abovementioned classification was: at 20.1 weeks of gestation the anteroposterior diameter of the left renal pelvis was 4.5 mm; at 24 weeks of gestation it was 5.3 mm; at 28 weeks of gestation it was 8.1 mm; and at 30.5 weeks of gestation it was 11.2 mm. When re-evaluated by the Fetal and Pediatric Pathology Department, the diagnosis was grade 3 hydronephrosis.
Prenatal screening in Mexico is advancing with innovative technology and the urologist must become familiar with prenatal diagnoses to be prepared to meet this new challenge.
我们在此报告一个男性双胞胎胎儿肾脏扩张的超声随访。临床病例:一名29岁女性,3次妊娠,1次正常分娩,1次剖宫产,在瓜纳华托州Salud研究所(Pública del Estado de Guanajuato, ISAPEG)的机会筛查中心进行妊娠早期超声筛查,发现双绒毛膜双羊膜双胎妊娠,筛查结果阴性。在妊娠20.1周时,结构超声检查发现双胞胎中的一个左肾扩张。采用胎儿泌尿外科学会2010年产前肾积水分级标准对左肾盂扩张进行测量和分级。按上述分类发现肾积水的双胞胎左肾盂超声随访为:妊娠20.1周时,左肾盂前后径为4.5 mm;妊娠24周时为5.3 mm;妊娠28周时为8.1 mm;在妊娠30.5周时为11.2毫米。当胎儿和儿科病理部门重新评估时,诊断为3级肾积水。产前筛查在墨西哥正在推进创新技术,泌尿科医生必须熟悉产前诊断,准备迎接这一新的挑战。
