We present the case of a 29-year-old woman with a history of obstructive pyelonephritis who developed a calcified ureteral stent. This rare complication emphasizes the critical need for regular follow-up in patients with indwelling ureteral stents to prevent severe outcomes. The patient’s condition was effectively managed using a combination of endoscopic and surgical techniques, demonstrating a multidisciplinary approach to addressing such complex clinical scenarios. This case not only sheds light on the potential complications associated with ureteral stents but also underscores the importance of early detection and timely intervention to optimize patient outcomes.
