Prostate HDR radiation therapy: a comparative study evaluating the effectiveness of pain management with peripheral PCA vs. PCEA.

INTRODUCTION: High dose rate (HDR) brachytherapy is considered one of the most advanced treatment technologies currently available for treatment of localized prostate cancer. It gives the advantage of applying higher dose radiation, with greater precision, directly to the tumor while sparing healthy tissue and surrounding organs, thereby resulting in fewer side effects. In this facility, the treatment requires an overnight stay in the hospital, in a supine position, with a perineal template sutured to the perineum to prevent catheter movement or dislodgement. PURPOSE: To compare the effectiveness of pain management for men with prostate cancer being treated with HDR brachytherapy using a peripheral patient controlled analgesia (PCA) or patient controlled epidural analgesia (PCEA). METHOD: A comparative study was conducted evaluating the effectiveness of two pain management methods for men with prostate cancer receiving HDR brachytherapy. Pain assesments were conducted by scoring pain from the Foley catheter, interstitial catheter (perineal) and back (lumbosacral), using the Brief Pain Inventory Scale. RESULTS: Patients receiving pain management with the PCEA experienced significantly less pain. CONCLUSIONS: These finding suggest that use of PCEA with bupivacaine and fentanyl is more effective in managing pain related to HDR brachytherapy for prostate cancer, and results in a positive patient outcome thereby improving patient satisfaction.

Laparoscopic radical nephrectomy in renal cell carcinoma.

Historically, the only surgical option for removal of a renal mass was through a large incision in the abdomen. Recently, many urologists have adopted new innovations in the removal of renal masses including laparoscopic radical nephrectomy. The laparoscopic approach to radical nephrectomy has been associated with improved patient outcomes including decreased pain, shorter hospital stay, rapid recovery, and improved aesthetic cosmetic appearance. Laparoscopic radical nephrectomy may be performed in three different types of surgical procedures including laparoscopic hand-assisted radical nephrectomy, transperitoneal radical nephrectomy, and retroperitoneal radical nephrectomy. Understanding the procedure, preoperative instructions, and recovery will assist nurses in counseling patients considering laparoscopic radical nephrectomy.

Urolithiasis/nephrolithiasis: what's it all about?

Urolithiasis (urinary tract calculi or stones) and nephrolithiasis (kidney calculi or stones) are well-documented common occurrences in the general population of the United States. The etiology of this disorder is multifactorial and is strongly related to dietary lifestyle habits or practices. Proper management of calculi that occur along the urinary tract includes investigation into causative factors in an effort to prevent recurrences. Urinary calculi or stones are the most common cause of acute ureteral obstruction. Approximately 1 in 1,000 adults in the United States are hospitalized annually for treatment of urinary tract stones, resulting in medical costs of approximately dollar 2 billion per year (Ramello, Vitale, & Marangella, 2000; Tanagho & McAninch, 2004).

Exploratory factor analysis: strategies used by patients to promote health.

Strategies used by patients to promote health (SUPPH) was used to measure self-care self-efficacy in patients with cancer. The objectives of this study were (1) to determine the extent to which self-efficacy theory explained the factor structure of the SUPPH and (2) to determine the relationship of demographic data with factors of the SUPPH. Subjects were diagnosed with prostate cancer (PCa) and treated with either: (a) radical prostatectomy, (b) intensity modulated radiation therapy (IMRT) + radioactive seed implantation, or (c) IMRT + high dose rate. Subjects completed a demographic questionnaire and the SUPPH. Exploratory factor analysis of the SUPPH was performed using a varimax rotation. Subjects (n = 265) were predominately white and averaged 68 years of age. The model explained 81.3% of the total sum of eigenvalues. Two factors of the SUPPH were identified: physiological efficacy information and performance efficacy information. Younger subjects who were fully employed and earning more money had significantly higher performance self-efficacy than older subjects who were working part time and earning less money. Results are congruent with Bandura's (1997) description of self-efficacy. Use of the SUPPH may facilitate research validating Bandura's (1997) assertion that an individual's self-efficacy is related to quality of life (QOL) during chronic illness. Additional research focusing on self-efficacy and PCa patients' QOL may lead to efficacy enhancing interventions that will improve QOL of patients with PCa.

Prospective study of quality of life of patients receiving treatment for prostate cancer.

BACKGROUND: No research was found that compared quality of life (QOL) outcomes of prostate cancer patients receiving intensity-modulated radiation therapies with prostate cancer patients receiving radical prostatectomy. OBJECTIVES: To (a) describe differences in QOL before and after three types of treatment for prostate cancer: radical prostatectomy, intensity-modulated radiation therapy + seed implantation (permanent brachytherapy), or intensity-modulated radiation therapy + high dose rate radiotherapy (temporary brachytherapy); and (b) investigate demographic, physical, and psychosocial variables that impact QOL of men with prostate cancer. METHODS: Data were collected on three occasions: baseline (prior to treatment), 1 month, and 3 months after beginning treatment. Measures included biographic data, physiological, and psychological measures. Analysis of variance and hierarchical regression were used to examine patterns, describe differences, and identify predictors of QOL in the three treatment groups. QOL was conceptualized as a multidimensional construct that included physical, psychological, social, and functional well-being and prostate cancer concerns. RESULTS: Groups differed significantly in bowel and urinary symptom scores and prostate cancer concerns at baseline, and in urinary and depressive symptoms at 3 months. There were no significant group differences at 1 month. DISCUSSION: Significant differences were found in QOL as measured with the Functional Assessment of Cancer Treatment-Prostate after treatment with radical prostatectomy, intensity-modulated radiation therapy + seed implantation, or intensity-modulated radiation therapy + high dose rate radiotherapy. Findings may provide healthcare providers with knowledge about treatment sequelae for prostate cancer, enable healthcare providers to educate patients about QOL outcomes of treatment for prostate cancer, and enable patients to make more informed treatment decisions.
