Effect of the 'Double J Stent Placement Technique' on Early and Late Stent-Related Complications

Abstract

Objective: Currently, there is no globally accepted method for the Double J stent placement. We aimed to reveal the success and complication rates of the approach applied in our clinic and to show a prediction for clinics with similar technical backgrounds and facilities as ours. Material and Methods: The data of 774 patients who had double J stent placement in our clinic between January 2019 and January 2022 were reviewed retrospectively. Stent-related complication rates and independent risk factors affecting stent migration were analysed. Results: Nine hundred and seven double J stents were placed in 774 patients. The mean age of the patients was 54.3±20.1 (20-90). The indications for double J stent placement were; ureteral stones (46.5%), kidney stones (19.1%) and ureteral stenosis (34.4%), respectively. 91 (11.8%) of all patients had severe stent migration requiring additional intervention. Conclusion: Our study is the first in the literature investigating the relationship between the double J stent placement technique and stent migration. Our clinic's double J stent migration rate (11.8%) is similar to the stents placed under fluoroscopy, which were calculated with the stent length by various formulations in the current literature.
