The double pigtail stents are commonly used in urology. Their forgetfulness in the urinary ways leads to complications. The encrustation, fragmentation or migration are the most common complications. We conducted a four-year retrospective study to identify Demographic, clinical, radiological and therapeutic aspects of forgotten ureteral stents. Material and Methods: Retrospective study of 16 cases of forgotten and complicated ureteral stents lasts for four years. The encrusted stents were classified according to our own classification: KUB classification. Patients were treated by either extra corporeal shocwaves, endourology or open surgery according to a wellestablished therapeutic algorithm. Results: Average age: 36,6 years. The indications of ureteral stents were dominated by lithiasis: 87%. the average stenting time was 14.6 months. The Complications were dominated by the encrustation: 93%, with only one case of fragmentation and 4 cases of infection. The treatment was multimodal, combining several techniques mainly endourological, with an average number of entry to the operating room of 1.6. The average number of surgical procedures: 1.3. The average hospital stay is 4 days. Conclusion: The forgotten ureteral stents present a real problem of management. The extraction of the stent may require several surgical procedures which are stresfuls for the surgical team and the patient. Our classification allows a better therapeutic and prognosis correlation. Prevention must be at the forefront.
