Summary

This trial tests whether having an empty bladder before CT simulation for prostate cancer radiation therapy is better than the usual full bladder. The goal is to see if it reduces urinary symptoms and makes daily treatments more consistent. About 168 men with prostate cancer will be randomly assigned to either empty or full bladder preparation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
bladder filling procedure
What this could lead to
If it works, this could show that an empty bladder is just as good or better for radiation planning, reducing patient discomfort and treatment delays.
What could go wrong
This is a small, early-stage trial (168 participants) comparing two preparation methods, not a new treatment. Results may not change standard practice or apply to all patients.

Inclusion Criteria: * Age \>= 18 years * Histological confirmation of prostate cancer * Planned definitive dose radiotherapy to the prostate * Note: Patients are eligible for enrollment if they are already enrolled or planned for enrollment on another interventional research protocol provided that other study protocol treatment does not require procedures or treatments that would be in conflict with the eligibility or treatment protocols for this study nor, in the judgement of the enrolling physician, affect primary study objectives of this study * Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1, or 2 * Ability to complete questionnaire(s) by themselves or with assistance * Provide written informed consent Exclusion Criteria: * Planned delivery of radiotherapy to pelvic lymph nodes * Planned brachytherapy treatment of the prostate * Significant urinary incontinence that precludes standard bladder filling * Evidence of direct bladder extension or bladder wall metastases from prostate cancer * Used indwelling or intermittent urinary catheterization at baseline * Prior pelvic radiotherapy such that any portion of the prostate received \> 5 Gy
