ClinicalTrials.gov Identifier:	NCT00244309

Purpose

The purpose of this study is to determine whether a drug named tamsulosin (Flomax), or another drug named dutasteride (Avodart), or a combination of these two drugs is effective in improving urinary symptoms and decreasing the rate of intermittent self-catheterization after prostate brachytherapy.

Primary Outcome Measures:

AUA score will be used to assess severity of urinary symptoms. All patients will be contacted weekly by telephone for 12 weeks then monthly postoperatively to get their AUA score. A total of 21 AUA scores postoperatively.

Secondary Outcome Measures:

Use of intermittent self-catheterization

Estimated Enrollment:	348
Study Start Date:	November 2005
Study Completion Date:	June 2006
Primary Completion Date:	June 2006 (Final data collection date for primary outcome measure)

Detailed Description:

Image-guided transperineal permanent prostate brachytherapy (PI) is an accepted curative treatment option for patients with early stage prostate cancer. The most severe side effect of PI is urinary retention requiring intermittent self-catheterization (ISC). This study will assess the ability of pharmacologic intervention to ameliorate the post-operative side effect of PI. The use of both tamsulosin and dutasteride is proposed to have benefit in reducing urinary symptom score and in reducing the rate of intermittent self-catheterization for patients with prostate adenocarcinoma after prostate implant.

Eligibility

Ages Eligible for Study:	18 Years and older

Criteria

Inclusion Criteria:

Patient is eligible for a prostate implant
