Purpose- We present our experience with the use of metallic stents (wallstents) in the management of malignant ureteral obstruction in order to maintain renal function thereby permitting the use of chemotherapeutic agents treating the underlying malignancy. Materials and Methods- We retrospectively reviewed the records of 24 patients with ureteral obstruction secondary to advanced cervical carcinoma, stage T3b (n=10) and T4 (n=14), that was relieved by wallstents. Nineteen patients required bilateral and 5 required unilateral wallstents to relieve the obstruction. Fifty-six additional endourologic interventions were necessary to assure continued patency. Holmium laser ablation was utilized 14 times to manage tumor proliferation and ingrowth at the distal end of the stent. Thirty-two endostents, 4 extension and 6 replacement stents were used to maintain patency of the ureter. Results- Nineteen of our 24 patients received between 1-5 chemotherapeutic cycles over 18-140 months. In 5 patients, placement of wallstents did not achieve adequate decrease of the creatinine levels to allow treatment with chemotherapy. Thirteen of 24 wallstents remained patent over 18 months, yielding a primary patency rate of 54%. Technical success rate of wallstent placement was 100%. The overall mean primary and secondary patency rates of the stent was 16.5 and 52 months respectively. For T3b and T4 patients, the mean primary patency rate was 20.6 and 13.6 months respectively. Secondary patency for T3b patients was 73.9 months versus 36.4 months for T4 patients. There were no serious complications associated with wallstent placement. Conclusion. Wallstents offer a salutary solution to the problem of maintaining prolonged patency of ureters compromised by encasing neoplasms. |
