Results and complications of percutaneous nephrostomy

A series of 181 patients (158 with obstructive uropathy) treated by percutaneous nephrostomy (PN) in 1978-1987 is evaluated. In 8.3% of the patients PN did not succeed. The success rate of PN was lower when done outside normal working hours and before ultrasound guidance was used. Major complications occurred in 5.5% and minor ones in 10.5%. There was no direct mortality. The complications and the possible avoidance of them are discussed. In 68% of patients nephrostomy improved their clinical condition. The benefit of PN was closely related to the existing renal recovery potential following the relief of obstruction; a problem that has not yet been fully solved.
