单侧隐睾症患者睾丸大小及位置的术前超声评估

Evaluation of the preoperative testicular volume and location in children with unilateral cryptorchidismusing Ultrasonography

目的运用超声检查探讨单侧隐睾症患者年龄及睾丸所在部位与睾丸体积之间的关系。方法采用彩色多普勒超声检查双侧睾丸位置，测量睾丸各径线，计算睾丸体积。按年龄和睾丸所在位置分组。采用方差分析睾丸体积、年龄及睾丸所在位置的关系。结果608例年龄6个月至13岁经超声检查及手术证实的单侧隐睾患儿中，左侧306例，右侧302例。51例隐睾位于腹腔内，557例位于腹腔外。单侧隐睾患儿未下降睾丸位于腹腔内组与位于腹腔外组患侧睾丸体积比较无明显差异（P=0．658）；6个月至13岁各年龄组患儿患侧睾丸体积均明显较对侧睾丸体积小（P〈0．001）；单侧隐睾患儿双侧睾丸体积在1-11岁之间比较，差异无统计学意义（P〉0．05）。结论隐睾症对小于1岁的婴儿睾丸体积发育已造成影响，宜在1岁以前尽早手术。1-11岁双侧睾丸体积均未见明显变化，睾丸发育处于相对静止期。

Objective To investigate the correlation among the position of undescended testis, patient age,and testicular volume. Methods Color Doppler ultrasonography were used preoperative to detect the tes- ticular location and measure the diameters of both testes. The volumes of testes were calculated. Patients were divided randomly into groups according to location of undescended testis and patient age. ANOVA test was used for evaluate the correlation among the size of undescended testis, its locations and age groups. Results There were 608 unilateral cases （ranging in age from 6 months to 13 years）, including 306 left cases,302 right cases, 51 intra-abdominal, 557extra-abdominal. There was no statistically significant difference in testicular volume a- mong each position of the undescended testis （ P = 0. 658 ）. The undescended testis volume was significantly smaller than descended testis in the respective age groups（ P 〈 0. 001 ）. The volumes of both undescended and descended testis did not differ with age from 1year to llyears. Conclusion The growth of the undescended testes was already suppressed even before 1 year of age, so the operation should be recommended before one- year-old. The volumes of both undescended and descended testis did not differ with age from 1 year to 11 years.
