重复肾畸形的影像学检查价值与选择

目的 总结重复肾畸形的各种影像学检查的价值和选择原则.方法 1995年1月至2005年12月共收治小儿重复肾畸形41例,术前均行超声检查,其中26例(63.4%)获得诊断.24例行静脉肾盂造影(IVP)检查,其中15例(62.5%)获得诊断.12例行CT检查,其中8例(66.7%)获得诊断.12例行MRI检查,全部获得诊断.除2例外均经手术治疗.结果 41例患儿中30例(73.2%)获得随访,随访时间3-7年,平均4.8年.6例(20.0%)仍有反复尿路感染症状.其余患儿生长发育、排尿情况良好.结论 重复肾畸形病理类型可能简单或复杂,影像学检查方法多样,侧重点也各有不同.多种影像学检查方式的选择应该做到个体化.

Value and choice of imaging in duplex kidney

Objective To summary the value and choice of imaging in duplex kidney. Methods Forty-one patients with duplex kidney were admitted from January 1995 to December 2005. All were examined by ultrasound,of which 26 cases (63.4% ) were diagnosed preoperatively. IVP examination was done in 24 cases,of which 15 cases (62.5% ) were diagnosed. CT examination was done in 12 cases,of which 8 cases (66.7%) were diagnosed. MRI examination was done in 12 cases,all were diagnosed. Except 2 cases,the others were treated by surgery. Results Thirty cases (73.2% ) were followed up for 3 to 7 years,averaged 4.8 years. Of which 6 cases (20.0%) still had symptoms of recurrent urinary tract infections. Development and urination of the remaining children were in good condition. Conclusions Pathological types of duplex kidney may be simple or complex,and different imaging examination had different focuses. The selection of multiple imaging modalities should be individual.
