【摘要】：目的探讨高频超声对小儿腹外型未触及睾丸的诊断价值。方法对48例(53侧)腹外型未触及睾丸患儿,术前应用高频超声检查确定睾丸的部位、大小,并与手术病理学结果对比,分析睾丸残余与睾丸缺如结节大小、健侧睾丸大小的差异。结果高频超声诊断腹外型未触及睾丸的总检出率为83.02%(44/53),腹股沟型近区内环口处检出率为100%(4/4);腹股沟型伴嵌顿疝检出率为100%(2/2);睾丸残余及睾丸缺如检出率为80.85%(38/47)。声像图示小结节与腹股沟区低回声条索样精索结构相连,轮廓欠清,CDFI于内部均未探及明显血流信号。单侧腹外型睾丸残余结节长径[(0.71±0.08)cm]大于睾丸缺如结节[(0.62±0.14)cm],差异有统计学意义(F=4.698,P=0.037),而前后径及健侧睾丸大小差异均无统计学意义(P均0.05)。结论高频超声对腹外型未触及睾丸有一定的定位诊断价值,对临床手术方式、部位的选择有参考作用。
[Abstract]:Objective to evaluate the diagnostic value of high-frequency ultrasound in untouched testes of extraabdominal type in children. Methods 48 cases (53 sides) of untouched testes of extraabdominal type were examined by high-frequency ultrasound before operation to determine the location and size of testes, and compared with the results of operation and pathology, the size of residual and absent nodules of testis were analyzed. Differences in size of the contralateral testes. Results the detection rate of untouched testis was 83.02% (44 / 53), 100% (4 / 4), 100% (2 / 2), 100% (4 / 4), 100% (2 / 2), 100% (2 / 2) and 100% (2 / 2), respectively. The detection rate of testicular residual and absence was 80.85% (38 / 47). Sonographic images showed that the small nodules were connected to the structure of the low-echo cord-like seminal cord in the groin, and the outline was not clear. No obvious blood flow signal was detected by CDFI in the interior. The long diameter of unilateral extraventral type testicular residual nodule [(0.71 卤0.08) cm] was larger than that of testicular deficiency nodule [(0.62 卤0.14) cm], the difference was statistically significant (F = 4.698, P = 0.037). There was no significant difference between the anterior and posterior diameters and the size of the contralateral testes (P 0.05). Conclusion High-frequency ultrasound has certain value in localizing the untouched testes of extraabdominal type, and it can be used as a reference for the selection of clinical operation mode and location.
