Percutaneous nephrostomy has been effectively performed 107 times in 72 patients for relief of obstruction, drainage of urinary fistula and renal or extrarenal fluid collection, and functional preservation of urinary system, and follow-up check has been made for recent 3 years at Department of Radiology in Seoul National University Hospital. All procedures were successful and bilateral nephrostomy was done in 1 case of bilateral congenital UPJ obstruction. Percutaneous nephrostomy was done in left kidney in 38 cases (52.8%), permanent drainage was done in 55 cases (76.4%) and external drainage was done in 65 cases (90.3%), and the duration of follow-up was up to 8 months. Underlying diseases were supravesical obstruction in 63 cases (87.5%), urinary fistula in 3 cases, inflammatory disease in 5 cases and infravesical obstruction in 1 case. Satisfactory outcomes were made in 68 patients, whose BUN and serum creatinine levels have decreased near to upper normal range in at least 3 weeks. Major complications have occurred in 76 cases, catheter dislodgement or obstruction in 42 cases, fever in 10 cases, perirenal extravasation in 2 cases and periureteral leakage in 2 cases, etc. These complications can be prevented by adequate method using Seldinger technique under ultrasonography, CT or fluoroscopy, prophylactic and post-nephrostomy antibiotics, use of disposable catheter kits, frequent irrigation of the catheter and dressing of catheter fixation site when contaminated, prevention of extraction of the catheter dut to patient's carelessness, adequate fixation of the catheter to skin, and continuous follow-up of patients. It is expected that the territory of this interventional procedure will be extended by instrument insertion and drug instillation through the nephrostomy tract.
