Recurrent adult urinary tract infection secondary to unrecognized ureterocele urolithiasis

Abstract Background A ureterocele is a cystic dilation of the distal ureter, most commonly presenting as a congenital abnormality that may be associated with other renal anomalies. Ureteroceles present in a variety of manifestations in both children and adults, from asymptomatic to significant flank pain with urolithiasis or recurrent urinary tract infections (UTIs) that often mimic other more common renal pathologies, owing to its challenging clinical diagnosis. Case Presentation We report the case of a 78‐year‐old female patient who presented with recurrent UTIs and failure to thrive, complicated by a large stone that first presented in the bladder on computed tomography scan and was later found in the distal right ureter. Conclusion This case underscores the varied and often deceptive clinical presentation of ureterocele, stressing the importance of timely diagnosis to prevent secondary complications.
