Therefore, strategies to maintain the health of the peritoneal membrane are very important. A 64-year-old female who had been undergoing continuous ambulatory peritoneal dialysis (CAPD) for the past 6 years was admitted because of painless gross hematuria. On abdominal computed tomography (CT), a mass was found in her left renal pelvis. A nephroureterectomy was performed via a retroperitoneal approach without any complications. Peritoneal dialysis was resumed 4 hours later. We report peritoneum-preserving nephroureterectomy via a retroperitoneal approach in a patient on CAPD.

Microscopically, the left pelvis revealed papillary urothelial carcinoma, confined to the subepithelial connective tissue without invasion of the renal parenchyma. The tumor consisted of atypical urothelial cells with papillary growth (A, H&E stain, 100). The papillary architecture was well preserved and showed a moderate degree of nuclear pleomorphism (B, H&E stain, 400). B 로좌측콩팥요관절제술을시행받았으며그과정은다음과같다. 환자를우측측와위로눕히고좌측 12번째늑골위에서배꼽직상방으로 15 cm 피부절개후배바깥빗근 (obliquus externus abdominis), 배속빗근 (obliquus internus abdominis), 배가로근 (transversus abdominis muscle), 배가로근막 (transversalis fascia) 순으로열어복막을내측으로이동시키고복막뒤공간을연후신장을둘러싼제로타근막 (Gerota s fascia) 을확인하였다. 좌측신장은 6 5 3 cm으로위축되어있었고, 주변과유착은없었다. 콩팥요관절제술시행후, 수술중손상된복막을보강하였다. 복막뒤공간내에출혈이없음을확인하고배액관을유치한후수술을마쳤다. 적출신에서신우종양은신실질을침범하지않은고등급유두상요로상피세포암종 (papillary uroepithelial carcinoma, high grade) 으로조직학적진단하였고 ( 그림 3), 병기는 T1N0M0 stage I이었다. 환자는수술후 4시간지나서복막투석을재개하였고, 이후현재까지합병증없이 1일 4회의정규적인복막투석을성공적으로수행하고있다. 고찰현재많은말기신질환환자가이용하는복막투석은혈액투석에비해시간활용이더자유로우며, 혈역학적안정이필요한심부전및협심증환자와혈관질환이있는경우에더선호되는신대체요법이다 7). 그러나복막은다양한요인에의해그생리적기능을발휘할수없게된다. 당뇨병등의 기저질환, 복막투석액에포함된고농도의당과그에따른당분해산물, 생체부적합완충제, 잦은복막염등은복막의섬유화와혈관경화를포함한복막의변화를초래하여복막의기능을저하시킨다. 복막투석과관련하여발생할수있는탈장, 도관의이동, 엉킴, 그물막쌈등의합병증은치료를위해외과적수술이필요하므로결국복막손상을유발하게된다 3-5). 복막투석환자에서외과적응급상황이나종양이발생한다면외과적수술이필요하게되어복막을손상시킬수있다 6). 후천성낭성콩팥병과콩팥세포암은혈액투석을하는말기신질환환자에서유병률이증가하는것으로알려져있다 8,9). 한연구에서는지속적외래복막투석환자에서도혈액투석환자와비교하여후천성낭성콩팥병의유병률에차이가없었고 (41.1% vs. 47.1%), 콩팥세포암도발생하였다 (0.4% vs. 1.5%) 10). 본증례에서진단된요로상피세포암은일반인과비교하여혈액투석환자에서유병률이높으며 11), 현재일반적으로유병률이증가하는추세에있다 12). 이러한비뇨기계암은수술적치료가반드시필요하므로수술에따른복막손상을줄이기위한노력이요구된다. 상부요로비뇨기계에서발생하는요로상피세포암은전체요로상피세포암의 5% 내외를차지하는아직까지비교적드문암이지만 13), 37~52.3% 에서고등급의분화를보이며 43~ 61% 에서 T2 이상의 stage를보이는비교적공격적인암이다 14,15). 따라서현재상부요로비뇨기계에서발생하는요로상피세포암은방광주위박리를포함한개방콩팥요관절제술 - S 137 -
