[Internal urinary diversion in pelvic cancers and quality of life. Value of double "J" endoprosthesis].
The ureteral double pigtail stents are versatile and valued for proper urinary drainage in the setting of trauma, fistula formation, after extra-corporeal shock wave lithotripsy (ESWL) and surgical manipulations of the upper urinary tract. Also they are used for prolonged urinary drainage in patients with chronic tumor-induced ureteral obstruction, and present an exceptional patient tolerance. The authors' experience is based upon 54 patients treated for ureteral obstruction of malignant origin between January 1989 and October 1995. Complications of this method as well as the quality of life of these patients are analysed and the results compared with those of the literature. The patient tolerance was excellent. Mean survival time after ureter catheterisation was 18 months. Complete urine diversion was achieved and hydronephrosis disappeared soon after stent placement in 42 patients (80%). In addition hydronephrosis persisted in 12 cases (20%), despite orthotopic positioning of the catheter and numerous stent changes for larger caliber stents. The palliative use of the double pigtail stent when no other treatment is possible for malignant ureteral obstruction, precludes the need for ureterostomy and offers the patient a comfortable quality of life. Bladder disease is a contraindication to the use of these catheters, although their insertion is rarely impossible. In case of acute obstruction, it is better to prepare the pathway with a standard ureteral catheter, which is easier to manage. It is always possible to insert the pigtail stent after some time has elapsed.
