The goal of this clinical research study is to learn how the body absorbs and processes 1 dose of cidofovir that is given directly into the bladder, in patients with a viral infection that is causing bleeding from the bladder.

The safety of this drug dose and the investigational way it is given (directly into the bladder) will also be studied.

Cystitis Bladder Diseases Drug: Cidofovir

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Enrollment: 0
Study Start Date: September 2012
Estimated Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
