Percutaneous nephrostomy
Abstract
- Percutaneous nephrostomy was performed in 82 patients under the fluoroscopic guidance for recent 3 years. Thecauses of hydronephrosis were as follows: unknown origin of stricture(N=37), stone(N=20), tumor (N=14),tubeculosis(N=8), postoperative ureteral injury(N=1), postoperative anastomotic stricture(N=1) and renaltrasplantation complication(N=1). Successful nephrostomy was achieved in 79 patients(96%). Causes of failure wereminimal dilatation of pelvocaliceal system (N=2) and staghorn calculi(N=1). Follow up laboratory test shows highBUN and creatinine level retruned to normal limit within 1 or 3 weeks in 73 patient. Major complication was notfound, but temporary hematuria (N=4) or fever(N=1) was noted. In conclusion, percutaneous nephyrostomy is the safeand effective method for the temporary and permanent relief of urinary obstruction and the maintenance of ureteralpatency.
