초록

목 적 : 정류고환은 소아비뇨기영역에서 가장 흔한 기형으로 여러 합병증을 일으키며, 그 중 비촉지성 정류고환은 전체 정류고환 중 약 20%를 차지한다. 비촉지성 정류고환의 진단방법은 여러 가지가 있으나 아직 확립되지 않아 임상에서 통상적으로 적용될 수 있는 비촉지성 정류고환의 진단방법을 알아보고자 하였다. 방 법 : 2000년 3월부터 2005년 2월까지 본원에서 수술한 정류고환 129례 중 비촉지성 정류고환 31례를 대상으로 초음파검사, 전신마취하 신체검사, 복강경검사를 실시한 후 각 검사의 효과와 필요성을 분석하였다. 결 과 : 비촉지성 정류고환 31례에서 초음파검사상 13례(41.9%)에서 고환을 발견하였고 18례(58.1%)에서 고환을 발견할 수 없었고, 전신마취하 신체검사상 15례(48.4%)에서 고환을 촉지하였고 16례(51.6%)에서 고환을 촉지할 수 없었다. 초음파 검사와 전신마취하 신체검사에서 고환을 발견 못한 16례를 대상으로 복강경 검사를 실시하여 16례 고환 모두의 위치와 상태를 알 수 있었다. 결 론 : 신체검사상 고환을 촉지할 수 없는 비촉지성 정류고환에서 초음파검사, 전신마취하 신체검사, 복강경검사 순으로 진행하는 것이 비용과 효과 면에서 가장 좋은 진단과정으로 생각한다.

Purpose : Numerous methods exist for diagnosing nonpalpable testis in treatment of cryptochidism. However, there is no clinically established data for the rational diagnostic tool of nonpalpable testis in terms of expenses. We tried to establish a current conventional diagnostic course of nonpalpable testis. We then evaluated the efficacy of ultrasonography, physical examination under general anesthesia and laparoscopy for diagnosing nonpalpable testis. Methods : Between March 2000 and February 2005, 103 boys(129 testes) with undescended testes were treated in our department. There were 31 testes(24.0%) that were not palpable at physical examination. These patients were evaluated with ultrasonography and repeated physical examination under general anesthesia. In the cases where testes could not be detected with ultrasonography and physical examination under general anesthesia, laparoscopy was performed to diagnose nonpalpable testis. Results : In 31 cases of nonpalpable testis, 13 testes were detected with ultrasonography and 15 testes became palpable with physical examination under general anesthesia. All of the remaining 16 nonpalpable testes were confirmed with laparoscopy. Conclusion : Physical examination under general anesthesia was superior to ultrasonography in making a diagnosis of nonpalpable testis. Ultrasonography and physical examination under general anesthesia could reduce the incidence of diagnostic laparoscopy. Therefore, it is recommended that ultrasonography, physical examination under general anesthesia and laparoscopy must be performed conventionally in order to diagnose nonpalpable testis.
