Abstract
A 23-year-old, previously healthy female presented with lower abdominal pain and mildly elevated creatinine one month following a right ureter stent for non-specific ureteral thickening causing obstruction. On admission, computed tomography (CT) revealed moderate hydronephrosis of the left kidney that would require stent placement as well. During stent placement, it was noted that the gross appearance of the ureters resembled ureteritis cystica. Biopsies were taken and showed signs of chronic inflammatory changes consistent with this diagnosis. Interestingly, this patient had no obvious medical history suggesting a cause for this process. She had been otherwise healthy with no recurrent episodes of urinary tract infection, nephrolithiasis, or sexually transmitted infection. The patient was discharged symptom-free following stent placement and will follow with urology for future stent replacements and clinical monitoring.
Highlights
Ureteritis cystica (UC) is a rare, benign condition of the ureters consisting of multiple, small submucosal cysts
We present an unusual bilateral case of UC in a 23-year-old healthy woman with no history of the predisposing risk factors mentioned above
Many studies have shown the causes of UC to be nephrolithiasis and urinary tract infections
Summary
Ureteritis cystica (UC) is a rare, benign condition of the ureters consisting of multiple, small submucosal cysts It usually occurs in middle-aged to elderly females following chronic urolithiasis or recurring urinary tract infections. A 23-year-old woman presented with left lower quadrant abdominal pain and mildly elevated creatinine of 1.21 mg/dl (baseline 0.8-1 mg/dl) that was identified on routine blood draw at a one-month follow-up urology appointment. She had no urinary symptoms at that time and the review of systems was otherwise unremarkable. The patient was discharged home symptom-free and proceeded with close urological follow-up
