Circle tube nephrostomy --Nephrostomy tubeならびにConnectorの試作--

Abstract

circle tube nephrostomyを男性7例, 女性10例, 計17例に施行し, 手術操作とcircle tube交換の操作を容易にするため, 千葉大式のcircle tubeならびにconnectorを作製した.手術前後の腎機能をPSP, Ccrで比べてみると正常化12例(71%), 改善4例(24%), 不変1例で悪化例は認めなかった.水腎の程度も全例改善した.合併症としては5例29%に尿もれがみられたが一時的であった.発熱, 腎出血, 尿路結石形成はみられなかった

We performed circle tube nephrostomy in 17 patients using a newly designed catheter. The catheter which we called 'Chiba Nephrostomy Circle tube' consisted of a silicon tube which has three holes in the middle portion, and a metal connector. The renal function recovered to normal in 12 of the 17 patients (recovery rate 71%), improved in 4 (24%), and remained unchanged in only one patient. Although temporal urinary leakage occurred in 5 patients (29%), there were no serious complications with this newly designed tube. Furthermore, pyelonephritis, renal bleeding and urolithiasis, which occasionally occur by single nephrostomy, did not occur with this method. Thus, we proved the clinical usefulness of the newly designed circle tube.
