“…Metal stents as a treatment option for MUO have the advantage to combine high pressure resistance, tensile strength, with exibility and strong corrosion resistance [22,23]. Liatsikos et al reported 100% effectiveness of urinary drainage in 25 patients with MUO treated with the Resonance metallic stent without stent displacement the 11 month follow-up period.…”

Objective. To evaluate the safety and efficacy of the Allium covered metallic stent for the treatment of malignant ureteral obstruction. Patients and Methods. Clinical data of 29 patients who underwent endoscopic insertion of an Allium ureteral stent between October 2019 and August 2021 at Yongchuan Hospital, affiliated with Chongqing Medical University, were analyzed retrospectively. At 1, 3, 6 and 12 months after insertion, serum creatinine was measured, the width of the renal pelvis was rechecked under ultrasound guidance, and the position and shape of the stent were checked by abdominal X-ray. Data on long-term stent patency, incidence of complications, changes in renal function and hydronephrosis grade were collected and analyzed. Ureteral stent symptom questionnaire (USSQ) was administered preoperatively and after 6 months in 22 patients with previous stent history. Results. Allium covered metal stents (n=33) were implanted successfully in 29 patients who were followed for 3 to 22 months, with 32/33 stents remaining patent. Serum creatinine levels decreased in 17 patients and hydronephrosis in 24 patients. Clavien-Dindo grade I complications were observed in 6 patients, Clavien-Dindo II in 1 patient, whereas stent displacement and stent encrustation occurred in one patient each (Clavien-Dindo III-IV). USSQ scores had significantly improved 6 months after stent insertion (p<0.001). Conclusion Allium ureteral stents are a safe and effective treatment option for malignant ureteral obstruction, with good long-term patency, helping to preserve renal function and improve quality of life.
