摘要 目的：探讨未触及隐睾的临床处理。方法：未触及隐睾22例26侧均先行hCG治疗，26侧均行手术探查。结果：hCG治疗后有3例单侧于腹股沟区可触及睾丸，1例双侧hCG激发试验阴性，2例单侧无睾丸，1例双侧睾丸发育不良。17侧睾丸固定于阴囊底肉膜外，5侧分期手术。随访17侧2～11年，其中回缩2侧，萎缩1侧。结论：未触及隐睾尚无一简便明确的方法可证实睾丸的存在，hCG激发试验可判断双侧隐睾患儿有无睾丸，但阴性者不能排除睾丸发育不良。手术探查应是目前首选的临床处理方法。

Abstract Objective: To review the management of impalpable testes.Methods: The management of twenty-six testes in 22 patients was studied. All patientsreceived hCG treatment. Four patients with bilateral undescended testes underwent the hCGstimulation test. The testes were then surgically ex plored. Results: Of the 18 patientswith unilateral undescended testes, 3 respo nded to hCG treatment and the testes becamepalpable in the groin. Two patients had agenesis of testis on exploration. One child withbilateral undescended testes did not respond to hCG stimulation. Another child was foundto have bilateral tes ticular dysplasia and the testes were removed. 17 testes were fixedin scrotum by subdartos pouch. Five patients underwent staged operations. Of the 17patients who were followed-up 2-11 years, two developed testicular retraction and one testicular atrophy. Conclusion: Negative hCG test does not preclude the presence of dysplastictestes in bilateral undescended testes. Surgical exploration is the treatment of choice.
