심한 신우요관이행부 협착에 대한 신배회장요관문합술의 경험

The treatment of a long segment stricture of the upper ureter, destroyed pelvis and ureteropelvic junction obstruction with intrarenal pelvis presents a difficult surgical question. A small isolated segment of the ileum was interposed between the lower pole calyx of the kidney and the ureter. This procedure takes advantage of the presence of normal and nonrefluxing ureterovesical junctions, and serves to diminish any potential problems of electrolyte imbalance and restricture of the ileal ureter. Here, a case of calycoileoureterostomy in a 32-year-old man, with an intrarenal pelvis and a severe ureteropelvic junction obstruction following pyelolithotomy, is described.
