Read the detailed description

A pooled 22 patients diagnosed with eosinophilic cystitis on microscopic examination in our hospital during four years were retrospectively studied.We explored the potential etiology, clinical and histopathology presentation of the eosinophilic cystitis cases, clinically mimicking urothelial neoplasia. Surgical procedure and clinical outcome also evaluated. Transurethral resection of the lesions were performed and pathologically examined, we re-examined the studied cases and made a clinical correlation.

  • Diagnostic testMicroscopic examination

    All the studies cases are microscopically examined using the ordinary stains (hematoxylin and eosin) then the eosinophilic infiltration are counted in 10 high power field manually

What researchers measure

Primary outcomes

  1. Eosinophil cell count

    Each tissue slide is retrieved and examined to count the eosinphils in the submucosa, positive cases revelaed more than 90% eosinophils of the whole inflammatory cells

    Time frame: 1 day

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 4, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
