서론: 양측성 신피질 괴사는 급성신부전 환자의 약 5% 미만에서 발견되는 드문 원인 중 하나이며 대부분 산부인과적 요인에 의해 야기된다 고 보고되고 있다. 이에 본 연자 등은 S자 결장 게실염 천공으로 인한 장절제술 시행 후 양측성 신피질 괴사에 의한 급성신부전이 발생한 예를 경험하고 보고하는 바이다. 증례: 특이 과거력 없는 70세 여자 환자로 하복부 동통, 발열 등을 주소로 본원 응급실을 내원하였다. 내원 당시 활력 징후는 혈압 150/80mmHg, 맥박 108회/분, 호흡 22회/분, 체온 38℃이었고, 말초혈액검사에서 백혈구 20,200/mm3, 혈색소 12.8g/dL 혈소판 272,000/mm3, 혈청 생화학검사에서 혈중 요소질소 (BUN) 16.6mg/dL, 크레아티닌 0.7mg/dL 소견을 보였다. 이후 복부 전산 화 단층 촬영술을 시행하여 S자 결장 게실염 의심하에 경험적 항생제 투여와 수액 요법을 시행하였다. 그러나 동통이 지속되고, 이학적 검사 에서 압통, 반발압통 소견 등을 보여 단순 복부 X-선 촬영을 시행하였으며 이후 장천공 의심하여 응급 결장 부분절제술과 충수돌기 절제술 을 시행하였다. 수술 도중 활력징후는 안정적이었다. 수술 후 2일째 혈압 160/80 mmHg, 맥박 88회/분, 호흡 22회/분, 체온 36.8℃이었고 말 초혈액검사에서 백혈구 15,000/mm3, 혈색소 10.4g/dL, 혈소판 81,000/mm3, 혈청 생화학검사에서 BUN 42.4mg/dL 크레아티닌 3.0mg/dL 소 견 보이면서 핍뇨 소견이 관찰되었다. 수술 후 4일째 무뇨 지속되고 혈청 BUN 111.3mg/dL, 크레아티닌 7.9mg/dL 소견 보이면서 대사성 산증, 급성 폐부종 등 요독 증세 악화되어 응급 혈액투석을 시행하였다. 수술 후 8일째 복부 전산화 단층 촬영을 재시행하였으며 이때 양측 성 신피질 괴사 소견이 관찰되었다. 수술 후 18일째 초음파 유도하에 경피적 신생검을 시행하였으며 급성 미만성 신피질 괴사 소견을 확인 하였다. 이후 간헐적 혈액투석 시행하면서 보존적 치료 시행하였으나 일일 요량 10mL 미만으로 유지되고 요독증 지속되어 수술 후 3개월 현재 주 3회 정기적인 혈액투석 시행 중이다.

Purpose: We analyzed colonoscopic findings in kidney transplantation recipients to compare with those in normal population. Methods: The Catholic University of Korea kidney transplant database was queried for kidney transplant recipients who underwent colonoscopy from Jan 2003 through Feb 2008.Of this population, patients with pretransplantation history of colorectal cancer or polyp were excluded. After this process, 240 kidney transplantation recipients were surveyed. To compare with normal Korean population, we quote from the article of Endoscopy 2006;38. Results: The mean interval between kidney transplantation and colonoscopy was 144 months(0 to 362). Mean recipients age was 51.2 years(21 to 77). Common reasons for colonoscopy were abdominal pain(21.2%) and bowel habit change(17.2%), but asymptomatic routine colonoscopic exams were also performed in 33.4% of the patients. We identified 168 polyps in 82 patients(34.2% of surveyed recipients). Mean number of polyp was 2.1 (1 to 13). Multiple polyps were found in 33 patients (36.1%) 66.4% of colorectal adenomas were found in the colon proximal to sigmoid colon. Biopsy showed 52 cases of tubular adenoma(59.8% of total polyps), 4 of adenocarcinoma (4.9%). 3 of villous adenoma(3.7%), 1 of Villotubular adenoma(1.2%), and 36 of nonadenomatous polyps(30.5%).

Interestingly, 17.6% of advanced colorectal neoplasm were found in the patients under the age of 50, who usually were not recommended for routine colonoscopy. Of the transplant recipients who developed cancer, the mean age at diagnosis was 63.5 years (52 to 79). Compared with normal Korean population, overall colorectal carcinoma incidence was higher in kidney transplantation recipients(1.7% vs 0.29%), while colorectal adenoma incidence was similar(22.1% vs 23.9%) in them. Conclusion: Earlier and more cautious colonoscopic screening should be considered in kidney transplantation recipients.
