초록

요로결석증으로 인한 급성 옆구리 통증은 환자들이 응급실로 방문하는 가장 흔한 질병이다. 연구의 목적은 수신증이 동반되지 않은 환자에서 컬러 도플러를 이용하여 요관결석 검출의 유용성에 대하여 알아보고자 한다. 신장, 요관, 방광의 단순 x-ray 검사에서 요로결석 의심 소견자 또는 소변검사에서 혈뇨 양성반응을 보인 161명의 환자를 대상으로 초음파 검사를 시행하고 후향적으로 분석하였다. 초음파검사에서 진단된 요관결석은 161명 환자 중 154례 (95.6%) 이었다. 수신증이 없고 컬러 도플러 초음파검사에서 섬광인공물(TA)을 동반한 요관결석은 21명 중 18례 (85.7%)이었다(p<0.001). 초음파는 비교적 저렴하고, 보편적으로 사용하므로 옆구리 통증을 갖는 환자의 요로결석 진단에 우선적으로 이용할 수 있다. 컬러 도플러를 이용하여 구분되지 않은 결석, 비확장성 요관결석, 중간요관 결석 검출에 높은 진단 효과를 갖는다.

Acute flank pain from urolithiasis is the most common condition in people visiting emergency rooms. This study is to evaluate the usefulness of color Doppler in detecting ureteral stones in patients without hydronephrosis. We performed ultrasonography and retrospective analysis on 161 patients who were suspected of urinary stones through plain radiography of the kidney, ureter, and bladder examination or urine tests that showed positive signs of hematuria. In ultrasonography, a total of 154 (95.6%) cases from the 161 patients were diagnosed with ureteral stones. In color Doppler, ureteral stones with twinkling artifact (TA) in the absence of hydronephrosis was shown in 18 (85.7%) cases of the 21 patients(p<0.001). The use of color Doppler has a high diagnostic efficacy for the detection of indistinguishable stones, non-dilatational ureteral stones, and middle ureter stones.
