Mechanisms, mitigation, and management of urinary toxicity from prostate radiotherapy.

Urinary toxicity is common following pelvic radiotherapy and can have a substantial negative effect on survivorship. Due to its prevalence and the increasing number of related clinical trials, localised prostate cancer radiotherapy is a useful illustrative tool to explore urinary toxicity. A good understanding of the interplay between anatomy, radiation-sensitive cell populations, and treatment sequencing is necessary for optimal outcomes. Emerging evidence suggests that the prostatic urethra is a radiation-sensitive structure, not only for stricture development, but also chronic irritative symptoms. Tools now exist not only to identify the urethra, but also to direct radiation dose away from the urethra, with early data suggesting that this reduces moderate-to-severe late urinary toxicity. Coupled with new evidence supporting dominant nodule microboosting and ultrahypofractionation as emerging standards of care, urethral sparing radiotherapy is a powerful tool against radiation induced urinary toxicity while also maximising disease control.

The use of portable video media vs standard verbal communication in the urological consent process: a multicentre, randomised controlled, crossover trial.

OBJECTIVES: To determine if portable video media (PVM) improves patient's knowledge and satisfaction acquired during the consent process for cystoscopy and insertion of a ureteric stent compared to standard verbal communication (SVC), as informed consent is a crucial component of patient care and PVM is an emerging technology that may help improve the consent process. PATIENTS AND METHODS: In this multi-centre randomised controlled crossover trial, patients requiring cystoscopy and stent insertion were recruited from two major teaching hospitals in Australia over a 15-month period (July 2014-December 2015). Patient information delivery was via PVM and SVC. The PVM consisted of an audio-visual presentation with cartoon animation presented on an iPad. Patient satisfaction was assessed using the validated Client Satisfaction Questionnaire 8 (CSQ-8; maximum score 32) and knowledge was tested using a true/false questionnaire (maximum score 28). Questionnaires were completed after first intervention and after crossover. Scores were analysed using the independent samples t-test and Wilcoxon signed-rank test for the crossover analysis. RESULTS: In all, 88 patients were recruited. A significant 3.1 point (15.5%) increase in understanding was demonstrable favouring the use of PVM (P < 0.001). There was no difference in patient satisfaction between the groups as judged by the CSQ-8. A significant 3.6 point (17.8%) increase in knowledge score was seen when the SVC group were crossed over to the PVM arm. A total of 80.7% of patients preferred PVM and 19.3% preferred SVC. Limitations include the lack of a validated questionnaire to test knowledge acquired from the interventions. CONCLUSIONS: This study demonstrates patients' preference towards PVM in the urological consent process of cystoscopy and ureteric stent insertion. PVM improves patient's understanding compared with SVC and is a more effective means of content delivery to patients in terms of overall preference and knowledge gained during the consent process.

The Australian laparoscopic non robotic radical prostatectomy experience - analysis of 2943 cases (USANZ supplement).

OBJECTIVES: To analyse the Australian experience of high-volume Fellowship-trained Laparoscopic Radical Prostatectomy (LRP) surgeons. MATERIALS AND METHODS: 2943 LRP cases were performed by nine Australian surgeons. The inclusion criteria were a prospectively collected database with a minimum of 100 consecutive LRP cases. The surgeons' LRP experience commenced at various times from July 2003 to September 2009. Data were analysed for demographic, peri-operative, oncological and functional outcomes. RESULTS: The mean age of patients were 61.5 years and mean preoperative PSA 7.4 ng/ml. Mean operating time was 168 minutes with conversion to open surgery in 0.5% and a blood transfusion rate of 1.1%. Overall mean length of stay was 2.5 days. 73.6% of pathological specimens were pT2 and 86.3% had Gleason Score >7. Overall positive surgical margins (PSM) occurred in 15.9% with pT2 PSM 9.8%, pT3a PSM 30.8% and pT3b PSM 39.2%. Mean urinary continence at 12 months was 91.4% (data available from five surgeons). Mean 12 months potency after bilateral nerve spare was 47.2% (data available from four surgeons). Biochemical recurrence occurred in 10.6% (mean follow up 17 months). CONCLUSION: The Australian experience of Fellowship trained surgeons performing LRP demonstrates favourable peri-operative, oncological and functional outcomes in comparison to published data for open, laparoscopic and robotic assisted radical prostatectomy. In our Australian centres, LRP remains an acceptable minimally invasive surgical treatment for prostate cancer despite the increasing use of robotic assisted surgery.

Portable Video Media Versus Standard Verbal Communication in Surgical Information Delivery to Nurses: A Prospective Multicenter, Randomized Controlled Crossover Trial.

BACKGROUND: Continuing education of health professionals is important for delivery of quality health care. Surgical nurses are often required to understand surgical procedures. Nurses need to be aware of the expected outcomes and recognize potential complications of such procedures during their daily work. Traditional educational methods, such as conferences and tutorials or informal education at the bedside, have many drawbacks for delivery of this information in a universal, standardized, and timely manner. The rapid uptake of portable media devices makes portable video media (PVM) a potential alternative to current educational methods. OBJECTIVE: To compare PVM to standard verbal communication (SVC) for surgical information delivery and educational training for nurses and evaluate its impact on knowledge acquisition and participant satisfaction. DESIGN: Prospective, multicenter, randomized controlled crossover trial. SETTING: Two hospitals: Gosford District Hospital and Wyong Hospital. PARTICIPANTS: Seventy-two nursing staff (36 at each site). INTERVENTION: Information delivery via PVM--7-minute video compared to information delivered via SVC. OUTCOME MEASURES: Knowledge acquisition was measured by a 32-point questionnaire, and satisfaction with the method of education delivery was measured using the validated Client Satisfaction Questionnaire (CSQ-8). RESULTS: Knowledge acquisition was higher via PVM compared to SVC 25.9 (95% confidence interval [CI] 25.2-26.6) versus 24.3 (95% CI 23.5-25.1), p = .004. Participant satisfaction was higher with PVM 29.5 (95% CI 28.3-30.7) versus 26.5 (95% CI 25.1-27.9), p = .003. Following information delivery via SVC, participants had a 6% increase in knowledge scores, 24.3 (95% CI 23.5-25.1) versus 25.7 (95% CI 24.9-26.5) p = .001, and a 13% increase in satisfaction scores, 26.5 (95% CI 25.1-27.9) versus 29.9 (95% CI 28.8-31.0) p < .001, when they crossed-over to information delivery via PVM. LINKING EVIDENCE TO ACTION: PVM provides a novel method for providing education to nurses that improves knowledge retention and satisfaction with the educational process.

COVID-19 had no impact on emergency urological admissions at an Australian tertiary hospital.

BACKGROUNDS: The COVID-19 pandemic is an unprecedented threat to health and healthcare systems. There is no published data on the impact on urological presentations in Australia. METHODS: A retrospective analysis of all admissions under the urology service at Liverpool Hospital, Australia from February 1st to April 30th for 2020 and the previous 5 years. RESULTS: There was a total of 397 admissions in 2020 and 438 in 2019. The mean age, proportion of male, and mean length of stay were similar. In 2020, there were 229 emergency admissions. Over the same period during the previous 5 years, there were between 195 and 218 emergency admissions. In 2019, there were 220 planned admissions and 168 in 2020. Between 2019 and 2020, there was no significant difference in the proportion of patients with admission longer than 10 days (P = 0.602), requiring intensive care unit admission (P = 0.708) or inpatient operative management (P = 0.171). Among the emergency admissions, the mean Charlson Comorbidity Index was significantly lower in 2020 compared to 2019 (P = 0.009). CONCLUSIONS: Despite the pervasive fear of the COVID-19 pandemic and multiple, substantial alterations to hospital systems, structures and elective operating restrictions, no significant difference in numbers or acuity of emergency admissions were observed. Due to limitations in elective operating, there was an expected reduction in planned admissions. Our findings are in contrast to multiple recent studies and may be the result of our patient demographic where health-seeking behaviours appear to have not been significantly influenced by the pandemic.

The Australian laparoscopic radical prostatectomy learning curve.

BACKGROUND: International estimates of the laparoscopic radical prostatectomy (LRP) learning curve extend to as many as 1000 cases, but is unknown for Fellowship-trained Australian surgeons. METHODS: Prospectively collected data from nine Australian surgeons who performed 2943 consecutive LRP cases was retrospectively reviewed. Their combined initial 100 cases (F100, n = 900) were compared to their second 100 cases (S100, n = 782) with two of nine surgeons completing fewer than 200 cases. RESULTS: The mean age (61.1 versus 61.1 years) and prostate specific antigen (7.4 versus 7.8 ng/mL) were similar between F100 and S100. D'Amico's high-, intermediate- and low-risk cases were 15, 59 and 26% for the F100 versus 20, 59 and 21% for the S100, respectively. Blood transfusions (2.4 versus 0.8%), mean blood loss (413 versus 378 mL), mean operating time (193 versus 163 min) and length of stay (2.7 versus 2.4 days) were all lower in the S100. Histopathology was organ confined (pT2) in 76% of F100 and 71% of S100. Positive surgical margin (PSM) rate was 18.4% in F100 versus 17.5% in the S100 (P = 0.62). F100 and S100 PSM rates by pathological stage were similar with pT2 PSM 12.2 versus 9.5% (P = 0.13), pT3a PSM 34.8 versus 40.5% (P = 0.29) and pT3b PSM 52.9 versus 36.4% (P = 0.14). CONCLUSION: There was no significant improvement in PSM rate between F100 and S100 cases. Perioperative outcomes were acceptable in F100 and further improved with experience in S100. Mentoring can minimize the LRP learning curve, and it remains a valid minimally invasive surgical treatment for prostate cancer in Australia even in early practice.

Sticking to the facts: a systematic review of fibrin glue for pilonidal disease.

BACKGROUND: Pilonidal disease occurs when hair invading the natal cleft causes inflammation and abscess formation. Opinions vary on best practice, and most procedures have considerable morbidity and high recurrence rates of 6-40%. OBJECTIVES: This study systematically reviews the use of fibrin glue in the treatment of pilonidal disease. Outcomes measured were healing time and recurrence rate. DATA SOURCE: ScienceDirect and PubMed databases were searched for relevant literature, yielding seven papers including five small trials. The total number of patients receiving fibrin glue treatments across all trials was 85. There were no exclusion criteria in this review. RESULTS: Fibrin glue treatments had equivalent or better reported healing times than conventional therapies at an average of 2-6 weeks, and low recurrence rates between 0 and 17% at follow-up periods between 4 and 28 months. Considerable heterogeneity in study methodologies and surgical techniques prevented statistical significance or aggregate figures from being determined. CONCLUSIONS: There appears to be early promise for the use of fibrin glue in the treatment of pilonidal disease and an impetus for definitive research.
