Hong, Sung Joon; Lee, Moo Sang

Abstract

Percutaneous nephrostomy and indwelling ureteral stents are basic. endourologic procedures. We used .35 percutaneous nephrostomy catheters in 23 patients and success in 33 cases (94%). There were 4 complications; Obstruction due to blond clot in 3 and accidental removal in 1. In cases of internal ureteral stenting, we used 122 stents in 102 patients and success in 105 cases (86%). In operative cases, success rate was 100%, but 70% in retrograde ureteral stenting and 25% in antegrade ureteral stenting. Upward and downward migration, encrusted obstruction, severe pyelonephritis and persistent gross hematuria were occurred as complications. Although there were some complications marked improvement of uremic condition was noticed in majorities of patients. In these results, we have found the percutaneous nephrostomy. and .internal ureteral stentings were reliable in patients with ureteral obstruction, as adjuncts to genitourinary. surgery in selected instances and as external or internal diversion for patients with obstructive uropathy.
