Re-evaluation of indications for percutaneous nephrostomy and interventional uroradiological procedures in pelvic malignancy.
Twenty-two patients with advanced cancer involving the pelvis were treated by percutaneous uroradiological techniques. Percutaneous nephrostomy was performed for renal failure or urosepsis or before chemotherapy. In 8 patients, ureteric stents were also placed by the antegrade route, across malignant ureteric strictures, following nephrostomy. In another 8 patients, the ureteric obstruction could not be crossed and permanent nephrostomies were required. Fifteen patients were able to achieve a useful life but in the other 7 patients there was no improvement in their quality of life and they all died 1 month after intervention. Percutaneous nephrostomy also contributed to the death of 1 patient. Not all obstructed kidneys require drainage and in patients with disseminated or advanced disease involving the pelvis, the indications for intervention need to be individually assessed. An improvement in laboratory criteria of renal function following intervention does not necessarily result in improvement in quality of life. This retrospective study highlights the difficulty in selection of patients with advanced disease for intervention and previously suggested guidelines for intervention are reviewed.
