1)ハンモック尿管回腸吻合術を14例に施行し,92.9%の逆流防止率を得,3例に腎盂腎炎,1例に尿管狭窄を認めた.吻合部の尿漏れや上部尿路結石を術後認めたものはなかった.2)この吻合法はKock pouchなどのcontinent reservoirに有用であり,nipple valveのような異物を使用せず,輸入脚不全もきたさないHammock nonrefluxing ureteroileal anastomosis was performed on 14 patients who had urinary tract reconstruction using ileal conduit (4), Kock pouch (3), modified Kock pouch with plicated efferent limb (1) and ileal neobladder (6). Radiographic examinations showed ureteral reflux of contrast medium in one patient (7.1%), ureteral stenosis in one patient (7.1%) and no urine leakage. Three patients had pyelonephritis (21.4%) and no one had any upper tract urolithiasis. This technique provides a simple and reliable antireflux mechanism into ileal segments without nonabsorbable material.
