title: Ureteral decompression in advanced nonurologic malignancies.
abstract: BACKGROUND
  The purpose of this study was to assess the morbidity and determine survival after ureteral decompression in patients with advanced nonurologic malignancies.
  
  
  METHODS
  Between June 1988 and June 1993 78 patients were referred to a single surgeon for ureteral decompression. Records were analyzed in relation to primary diagnosis, early and late complications, number of hospitalizations, and survival after decompression.
  
  
  RESULTS
  Seventy-two percent of patients initially underwent decompression endoscopically, and 28% required percutaneous nephrostomy placement at initial decompression. Complications occurred in 50% of patients and most commonly included infection (29%), stent obstruction and encrustation (28%), and gross hematuria (9%). The median survival for all patients after the first decompression procedure was 6.8 months (range 0.5-46.1), with an actuarial survival rate at 1 year of 55% and at 3 years of 30%. The eight patients with gastric/pancreatic cancer survived a median of just 1.4 months after decompression (range 0.77-11.8), with a 1-year actuarial survival rate of 12.5% and 3-year actuarial survival of 0%, which was significantly worse when compared with all other groups taken together or individually (p < 0.03).
  
  
  CONCLUSIONS
  Ureteral decompression procedures in patients with advanced cancer can be an important component of palliative care but are associated with significant morbidity (50%) in patients whose median survival is < 7 months. The role of ureteral decompression in patients with advanced gastric and pancreatic cancer is limited.
