Abstract
- 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 urinarysystem, and follow-up check has been made for recent 3 years at department of Radiology in Seoul NatinalUniversity 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 drainagewas done in 55 cases(76.4%) and external drainage was done in 65 cases (90.3%), and the duration of follow-up wasup to 8 months. Underlying disease were supravesical obstruction in 63 cases(87.5%), urinary fistula in 3 casses,inflammatory disease in 5 cases and infravesical obstruction in 1 case. Satisfactory outcomes were made in 68patients, whose BUN and serum creatinine levels have decreased near to upper normal range in at least 3 weeks. Major complications have occurred in 7 cases; symptomatic urinary infection in 3 cases, fracture of the catheterin 2 cases, pneumothorax in 1 case and sepsis in 1 case. Minor complications have occurred in 76 cases; catheterdislodgement or obstruction in 42 cases, fever in 10 cases, perirenal extravasation in 2 cases and periureteralleakage in 2 cases, etc. These complications can be prevented by adequate method duing Seldinger technique undnerultrasonography, CT or fluoroscopy, prophylactic and post-nephrostomy antibiotics, use of disposable catheterkits, frequent irrigation of the catheter and dressing of catheter fixation site when contaminated, prevention ofextraction of the catheter due 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 iterventional procedure will beextended by instrument insertion and drug instillation through the nephrostomy tract.
