The pigtail ureteral stent in the cancer patient

Nephrostomy has been the standard procedure for urinary diversion when ureters are obstructed by cancer. However, recent reports have revealed significant problems related directly to the nephrostomy. The indwelling, internal ureteral stent eliminates many of these problems. We herein describe the course and survival of 20 patients in whom the pigtail ureteral stent was used to relieve ureteral obstruction caused by cancer. In these cases an over-all prolonged longevity, better quality of life and fewer complications have been noted when compared to cases of nephrostomy diversions.
