Objectives: We evaluated the feasibility and effectiveness of
percutaneous urinary diversion in patients with obstructive uropathy,
Patients and Methods: A total of 206 percutaneous nephrostomies (PCNs)
(right-sided in 54, left in 56, and bilateral in 48) were performed in
102 male and 57 female patients 18 to 94 years old. In 125 patients,
malignancy was the underlying cause of the obstruction and in 30, benign
disease. In four patients, the cause remained unknown. In most patients
(N = 154), the access was guided with both ultrasound and fluoroscopy,
Results: Percutaneous nephrostomy was successful in 158 patients (99%).
Antegrade ureteral stenting was attempted in 48 patients with a success
rate of 81%. Fifteen days postprocedure, the mean urea and creatinine
concentrations had declined from 160.8 mg/mL to 63 mg/mL and from 6.9
mg/dL to 2.2 mg/dL, respectively. In 66% of the patients, renal
function returned to normal. In 28%, it improved with no need for
hemodialysis, while in 6%, there was no improvement. Advanced age and
prostate cancer were negative predictive factors for the improvement of
renal function, whereas the BUN and creatinine concentrations before the
procedure and performance of unilateral v bilateral nephrostomies were
not. We did not have severe complications. Three patients received
transfusions, and in one patient, a urinoma was drained percutaneously.
Patients with malignancy had a median survival of 227 days.
Conclusion: Percutaneous urinary diversion under radiologic guidance is
a safe and effective procedure for patients with obstructive uropathy.
