The frequency of malformations of the kidney and urinary tract is much higher in patients with chromosome aberrations than in the general population. Sixty to 100% of "cat-eye" syndrome, 60 to 80% of Turner, 75% of trisomy 8, 33 to 70% of trisomy 18, 50 to 60% of trisomy 13, and over 50% of triploidy and tetraploidy patients may have such abnormalities. Renal and urinary tract malformations should be looked for in all patients with chromosome aberrations. Moreover, a chromosome study is indicated in any fetus with an ultrasonographic evidence of urinary tract abnormality.
染色体畸变患者中肾脏和泌尿系统畸形的发生率远高于普通人群。“猫眼”综合征患者中有60%至100%、特纳综合征患者中有60%至80%、8号三体患者中有75%、18号三体患者中有33%至70%、13号三体患者中有50%至60%,以及三倍体和四倍体患者中有超过50%可能有此类异常。对于所有染色体畸变患者都应检查是否存在肾脏和泌尿系统畸形。此外,任何超声检查显示有泌尿系统异常的胎儿都需要进行染色体检查。
