Purpose: To review the management of a forgotten/retained double J stent and attempt to suggest protocols to prevent this scenario.
Materials and Methods: We included 12 patients with forgotten DJ stents who had their primary surgery done at our hospital between September 2019 and March 2021 and were unable to follow up due to the lockdown imposed for the COVID-19 pandemic.
Results: Twelve patients underwent their forgotten DJ stent removal by a combination of ESWL, cyst lithotripsy, and percutaneous nephrolithotomy. All the patients achieved complete clearance of the encrustations/stone and removal of forgotten DJ stent in a single sitting.
Conclusion: A forgotten DJ stent with encrustations and stone formation is a serious urological problem for the patient and the treating doctor. A stent is usually said to be forgotten if the indwelling time period is more than 3 to 6 months which was not intended by the treating doctor. In our series, the management and intervention depended on the patients' pre-op status, the severity of the encrustations, location, and the size of the stone. In patients with moderate-to-severe encrustations and stone presence, procedures such as CLT, ureteroscopy, and PCNL were performed. Forgotten/ retained stents are a source of severe morbidity and additional/unnecessary hospitalization. In our series, we suggested a few protocols that could be followed in order to prevent a forgotten DJ stent.
