Double-ended pigtail polyethylene stents in management of benign and malignant ureteric obstruction.
Surgical urinary diversion for incurable pelvic malignancy has a high morbidity and mortality, and external drainage provides less than ideal palliation. Six patients with ureteric obstruction caused by cancer have been managed by operative or endoscopic insertion of self-retaining polyethylene tubes. These techniques also have applications in non-malignant disease, and the treatment of two patients with benign ureteric stricture is described.
