Metallic stent in the treatment of ureteral obstruction: Experience of single institute

Abstract

Patients with ureteral obstructions can be treated sufficiently with the Resonance(®) metallic stent. Patients who had gynecological malignancies and received radiotherapy had a higher failure rate after Resonance(®) metallic stent insertion.

Efficacy and Safety of a Novel, Double-Layered, Coated, Self-Expandable Metallic Mesh Stent (Uventa™) in Malignant Ureteral Obstructions

“…[8][9][10] The success rate, however, was quite low (50%) in patients who had radiation therapy. 11,12 Furthermore, the Resonance has several limitations, such as necessitating periodic exchange, because it has a similar shape to the PS. 8,9,11,13 In addition, stent-related irritation has been reported in 0% to 56.5% of patients.…”

“…8,9,11,13 In addition, stent-related irritation has been reported in 0% to 56.5% of patients. 8,9,11,12 Additional large studies may be necessary to evaluate its efficacy in MUO and optimal patient selection. Two of three cases became overall successes after secondary Uventa stent placement; one case became an overall failure because the ureter was obstructed again after secondary stent placement from tumor progression.…”

“…Malecot-type catheters require a skin suture, while balloon catheters do not. Catheters that are indwelling in the renal pelvis are more secure than nephro-stent-type tubes [501].…”

Early Application of Permanent Metallic Mesh Stent in Substitution for Temporary Polymeric Ureteral Stent Reduces Unnecessary Ureteral Procedures in Patients With Malignant Ureteral Obstruction

“…5 23 However, like PDJ stents, they must be exchanged regularly, and stent-related irritation has been reported. 23,24 The Hemobahn Endoprosthesis (WL Gore & Associates, Newark, DE, USA) is completely covered with polytetrafluoroethylene. It was used in 29 obstructed ureters, but stent migration occurred in 22% of cases.…”
