Interstitial cystitis with Hunner lesion (IC/HL) can affect the upper urinary tract, causing ureteral stenosis. Regular imaging is crucial for monitoring patients with IC/HL.
Area of Science:
- Urology
- Nephrology
- Pathology
Background:
- Interstitial cystitis with Hunner lesion (IC/HL) is a chronic bladder inflammation.
- Involvement of the upper urinary tract in IC/HL is rarely documented.
Purpose of the Study:
- To report a case of IC/HL involving bilateral ureteral stenosis.
- To highlight the importance of upper urinary tract surveillance in IC/HL patients.
Main Methods:
- A 51-year-old woman with IC/HL presented with bilateral ureteral stenosis and hydronephrosis.
- Diagnostic procedures included cystography, ureteroscopy, and histological examination.
- Treatment involved bilateral ureteral stenting and corticosteroid therapy.
Main Results:
- Ureteroscopy revealed severe ureteral stenosis due to mucosal hyperplasia.
- Histology confirmed chronic inflammatory changes compatible with IC/HL in the ureters.
- Bilateral ureteral stenosis persisted despite two years of corticosteroid treatment.
Conclusions:
- IC/HL can extend to involve the upper ureters, leading to stenosis.
- Regular imaging of the upper urinary tracts is recommended for patients diagnosed with IC/HL.
