What was measured

The AUASS has a total possible range of scores of 0-35 where 1-7 is considered mild symptoms, 8-19 is considered moderate symptoms, and 20-35 is considered severe symptoms. Questionnaires will be performed prior to treatment, and one and two years after completion of treatment.

Analysis population: Inadequate survey completion at specific time points

Groups in this outcome

Arm A (Moderate Dose SBRT With SIB)

Patients undergo 5 fractions of moderate dose SBRT with SIB every other day for 10 days following urethral-sparing IMRT planning. SBRT: 8.0Gy escalated dose Radiation Therapy Treatment Planning and Simulation: Undergo urethral-sparing IMRT planning SBRT: Undergo moderate dose SBRT with SIB

Arm B (Uniform Dose SBRT)

Patients undergo 5 fractions of uniform dose SBRT every other day for 10 days following urethral-sparing IMRT planning. SBRT: 7.5Gy conventional dose Radiation Therapy Treatment Planning and Simulation: Undergo urethral-sparing IMRT planning SBRT: Undergo uniform dose SBRT

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
