Assessment of sexual function following potentially curative local treatment for carcinoma of the prostate gland has resulted in wide ranges of potency preservation rates, which may be because of differences in the evaluated patient populations, mode of data collection, and length of patient follow-up. Quality-of-life data are most reliable when obtained by patient-administered and validated quality-of-life instruments. In the Schiffler Cancer Center's prostate brachytherapy unit, healthcare professionals utilize the specific erectile questions of the International Index of Erectile Function to ascertain pre- and post-treatment erectile function. Documentation of sexual function following all local treatments, including prostate brachytherapy, may help to clarify the etiology of treatment-induced erectile dysfunction (ED), improve treatment for ED, and, ultimately, improve quality-of-life outcomes. Fortunately, the majority of patients with brachytherapy-induced ED respond favorably to sildenafil citrate.

Prostate brachytherapy is a proven treatment for clinically localized prostate cancer; however, many clinicians have multiple misconceptions regarding patient selection criteria. Although most patients are candidates for the procedure, contraindications do exist. This article examines criteria for patient selection and the need for adjuvant therapies, proposes management philosophies, and discusses the impact of each on treatment decisions. Nurses' role in the decision-making process and how they can facilitate patients and families in making informed choices also are discussed. Clinical studies seek to further define patient selection criteria and examine optimal choices for adjuvant treatment and isotope preference. Expanding the knowledge base of nurses helps enhance patient care.

The increasing popularity of brachytherapy for treatment of early-stage prostate cancer requires oncology nurses to have a comprehensive knowledge of the disease, its treatment, and management of side effects. Because quality-of-life (QOL) issues have become an important consideration in treatment selection for many patients, oncology nurses must have a thorough understanding of these QOL issues and their management. Armed with knowledge about prostate brachytherapy and its effect on QOL, oncology nurses can offer accurate information and evidence-based symptom management techniques to patients undergoing brachytherapy for prostate cancer.
