A Challenging Case of Foreign Body Removal From the Bladder and Upper Urinary Tract

A 47-year-old female presented with a Proteus mirabilis UTI and bacteremia, right-sided hydronephrosis, and a large water-density bladder mass. She underwent right ureteral stent placement. The mass was too large for complete endoscopic removal. Partial resection revealed inflammatory cells and debris. She was referred to our facility for further management and presented to the emergency department with fevers, suprapubic pain, acute kidney injury, and worsening bilateral hydronephrosis with persistent bladder mass on imaging.
