OBSERVATIONAL
Conditions
Summary
This prospective multicenter observational study evaluates whether women ≥50 years with isolated acute hemorrhagic cystitis (AHC) and macroscopic hematuria require full malignancy workup. All participants undergo standard diagnostics (cystoscopy, CT urography, cytology), with 12-month follow-up for cancer detection. The aim is to identify low-risk patients where invasive investigations may be safely avoided.

- Cognitive impairment preventing informed consent.
- Ongoing or recent treatment for urological malignancy.
- Serious comorbidities affecting participation or safety.
