ABSTRACT

Introduction: The treatment of upper urinary tract´s obstruction is a surgical one and there are multiple therapeutic options. In spite of the appropriate use of minimally invasive techniques, there are still cases with unfavorable results that should keep permanent urinary diversions. As an alternative, it has been recommended the use of auto-expandable metal ureteral stents.
Objective: To show the preliminary results of the use of the Allium auto-expandable ureteral stent in Cuba.
Material and methods: Descriptive and prospective study in 12 patients who received a placement of 13 Allium´s auto-expandable ureteral stents between 2018 and 2019. Descriptive statistics were applied such as absolute frequency and percentage distribution.
Results: The average age was 49.4 years and 76.9 % were male. The most common cause of stenosis was the repeated endoscopic treatment of urolithiasis (69.2 %). The 91.6% of the patients were discharged the day after surgery. Complications were reported in four patients (30.7 %). The time of permanence of the stent covered between nine and 24 months for an average of 18.2 months.
Conclusions: The positioning of an auto-expandable ureteral stent is a feasible and safe alternative for the treatment of the upper urinary tract´s obstruction in selected patients. It is a minimally invasive therapeutic option that should be considered in Cuba for patients who have other permanent urinary diversions as JJ ureteral catheter or nephrostomy tube. It would be desirable a future evaluation considering a longer period of the stent´s positioning.
