Abstract

Twenty three endourologic diversion for obstructed upper urinary tract were performed in 20 kidneys of 18 Patients at Seoul National University Hospital during one year period ending August, 1983. These procedures include 13 percutaneous nephrostomies, 3 antegrade internal ureteral splints and 7 retrograde Double-J stents. Underlying diseases of 13 patients were malignant and 5 patients were benign disease. Most common indications were hydronephrosis with uremia in debilitated patients whose surgical risks were too high. A palliative diversion was performed in 15 kidneys and temporary diversion in 5. Encourologic diversion resulted in clinical improvement in 15 of 20 kidneys. Complications occurred in 3 of 23 procedures. There was 1 morality secondary to sepsis 24 hours after insertion of catheter. Most common problem was catheter blockade which was managed conservatively with irrigation in the most instances. However in 7 instance, catheter had to be changed or discontinued because of. complete obstruction. average duration of functioning catheter until blockade was 34-51 days. We found endourologic diversion is effective and economic procedure for palliative or temporary diversion, which was conventionally carried out by surgical intervention.
