DIP用Conrayによる片側通過過障害腎のDIPの検討

Abstract

DIP Conray is a 220 ml vial of 30 w/v % methylglucamine iothalamate. Drip infusion pyelography with a use of DIP Conray was applied to twenty non- or poorly-visualizing kidneys due to obstructive uropathy. DIP Conray visualized the renal outlines, calyces, pelves, ureters and bladders sharply and densely with a simple technique. Retrograde method was avoided in the cases of ureteral stone by DIP technique. DIP Con ray demonstrated the site of stricture of the ureters. Valuable DIP urograms of obstructive uropathy due to stones and strictures were able to be obtained within sixty minutes after injection of DIP Conray. Time of visualization of the pelves and ureters in the cases of hydronephrotic kidneys is delayed somewhat and so urogram can be obtained between one hour and two hours after DIP Conray injection in proportion to the reserved renal function of the affected kidneys. Values of hematocrit and serum creatinine were slightly elevated just after injection of DIP Conray. No significant changes of electrolytes were observed before and after injection of DIP Conray. In conclusion, any serious side effect was not observed in this series.
