Introduction: Ureteral stents are routinely used following endourological procedures to ensure adequate drainage and prevent obstruction. However, stent-related morbidity remains common, and optimal stent dwell time and removal methods are not well defined. This systematic review aimed to evaluate clinical and procedural factors influencing ureteral stent dwell time and the methods used for stent removal after endourological interventions. Methods: A systematic review was conducted in accordance with PRISMA guidelines and registered on PROSPERO. MEDLINE and Embase were searched from inception to October 2025. Randomized controlled trials and comparative observational studies evaluating ureteral stent dwell time and/or removal methods in adults undergoing endourological procedures were included. Risk of bias was assessed using RoB 2 and ROBINS-I tools. Results: Thirty-two studies encompassing 4,373 patients were included. Reported stent dwell times varied widely, most commonly ranging between 10 and 14 days in uncomplicated cases, with longer durations associated with increased rates of encrustation and removal difficulty. Removal techniques included rigid cystoscopy (48.7%), flexible cystoscopy (19.9%), extraction strings (23.5%), and device-assisted methods (7.9%). Less invasive approaches, particularly flexible cystoscopy and extraction-string removal, were consistently associated with reduced pain scores and improved patient comfort, although extraction strings carried a small risk of premature dislodgement. Conclusions: While practice patterns vary, the evidence suggests that a 10–14 day dwell time might be the optimal window to balance healing with the prevention of encrustation. Less invasive removal approaches, particularly flexible cystoscopy and extraction-string techniques, were generally associated with lower pain scores and high procedural success rates in selected patients. While these methods are safe and better tolerated, extraction strings carried a small, reproducible risk of premature dislodgement. High-quality prospective studies are needed to define determinant-based, individualized stent management strategies.
