Description of intervention(s) / exposure
Uroflow measurements at baseline, 6 weeks post end of radiation therapy treatment and then every 6 months for 5 years post radiation treatment for prostate cancer.
AUA surveys completed at baseline, 6 weeks post end of radiation therapy treatment and then every 6 months for 5 years post radiation treatment.
Radiation oncologists or a member of the study team will perform uroflow measurements at each follow up appointment and input data into database.
Each uroflow measurement takes approximately 5-10 minutes to complete.
This follow up will be performed at the radiation oncology centre in Toowoomba via face-to-face appointments.

Statistical methods / analysis
We estimate that we see approximately 350 patients with prostate cancer who receive radiation therapy in a year. The recruitment target for this study is defined by the number of
patients recruited during August 2020 until July 2023.
Patient AUA survey scores and uroflow measurements will be collated and compared against the dosages of radiotherapy to see if certain dosages predispose to the development of urethral strictures.
Patients will then be stratified into 3 outcome groups: no strictures, short term strictures (1-2 years) and long term strictures (3-5 years).
Confounding factors will be initially controlled for then multivariate analysis will be conducted to see if these factors can also predispose to urethral strictures.
Data will be collated in the form of a research paper. Preliminary results will be available after 3 years and may be presented at international conferences.
Target audience will be urologists, radiation oncologists, nurses, trainees, medical students and allied health professionals.
Data will be of mixed categorical and continuous type. The AUA surveys ask that patients rate their symptoms on a score of 0-5 with each question. Scores of 0-7 are classified as mild, 8-19 indicates moderate symptom severity and 20-35 indicates severe symptoms. Uroflow measurements look at the voiding time, flow time, maximum flow rate and volume voided. These are continuous measurements

Summary
Brief summary
This study will aim to measure the incidence of urethral strictures that develop after external beam radiotherapy for prostate cancer.

Who is it for?
You may be eligible for this study if you are an adult with prostate cancer who is undergoing radiotherapy treatment at Icon Cancer Centre Toowoomba QLD, Australia.

Study details
All participants will need to do is attend an assessment session 6 weeks following the end of radiation therapy treatment and then every 6 months for 5 years. This assessment will involve surveys and a urine flow test that is performed in the clinic. This flow test involves urinating into a flow meter to measure urine flow. It is non-invasive and only takes five to ten minutes to complete.

It is hoped that the results from this study will help guide future radiotherapy treatment regimes and aid in the early detection of urethral strictures post-radiotherapy. Thus, leading to a reduction in invasive procedures and decreased overall morbidity. It will also fill the gap in the literature as there are currently no prospective trials on this topic.
