BACKGROUND: To study the outcomes and experiences of using metallic stents in treating patients with malignant ureteral obstruction (MUO), we examined the effects of metallic ureteral stenting using the Cook Resonance® stent in the treatment of MUO. METHODS: All patients who had a Resonance metallic stent inserted between April 2015 and March 2018 at one of multiple facilities were prospectively observed with a 1-year follow-up. The primary outcome was the patency rate of the metallic ureteral stent. The secondary outcomes included the complications (e.g., infection and fever). RESULTS: Although stent insertion was attempted in 50 patients, the stent could not be inserted as a ureteral stent in three patients due to severe ureteral stricture, and one ureteral cancer patient was excluded from the analysis. The remaining 46 patients' median age was 67 years (range 28-85 years) (16 males, 30 females). Twenty-four patients died during the study; their median survival time was 226 days. The median follow-up period for the censored patients was 355 days (range 16-372 days), and just seven patients were still alive without Resonance failure > 1 year later. The women's IPSS scores tended to be lower than those of the men. Regarding the OABSS score, although the women's total score tended to be low, the difference between the men's and women's scores was nonsignificant. The bacteria detected from urine culture after stent insertion were more gram-positive than gram-negative. CONCLUSION: Metallic ureteric stenting using the Resonance stent is safe and effective for treating MUO. Subjective symptoms were relatively less in the female patients.
