The impact of radiation dose to the urethra on brachytherapy-related dysuria

Dysuria is common after brachytherapy, but typically minimal in severity. Urethral doses did not predict for either dysuria severity or normalization. Although preimplant I-PSS was the strongest predictor of maximum dysuria and isotope the best predictor for dysuria normalization, robust predictors for brachytherapy-related dysuria were not identified.
