    ABSTRACT: To determine the incidence of burnout among UK and Irish urological consultants and trainees. The second objective was to identify possible aetiological factors and to investigate the impact of various vocational stressors that urologists face in their day-to-day work and to establish whether these correlate with burn out. The third objective was to develop a new questionnaire to complement the Maslach Burnout Inventory (MBI), but which would be more specific to urologists, as distinct from other surgical/medical specialties, and to use this in addition to the MBI to determine if there is a requirement to develop effective preventative measures for stress in the work place, and develop targeted remedial measures when individuals are affected by burnout A joint collaboration was carried out between the Irish Society of Urology (ISU) and the British Association of Urological Surgeons (BAUS). Anonymous voluntary questionnaires were sent to all current registered members of both governing bodies. The questionnaire comprised of two parts. The first part encompassed sociodemographic data collection and identifying potential risk factors for burnout, and the second utilized the Maslach Burnout inventory (MBI) to objectively assess for workplace burnout. Statistical analysis was performed using GraphPad Prism Version 6.0b for Mac OS X. To evaluate differences in burnout, 2x2 contingency tables and Fischer's exact probability tests were used to demonstrate statistical significance. P-values <0.05 were taken as statistically significant. A total of 575 urologists responded to the online survey out of a total of 1380 invites, yielding a 42% response rate. All respondents were below the age of 75 years old (Median age: 45 years), with males representing 87.5% of respondents. Seventy-five per cent respondents worked in England, followed by the Republic of Ireland (9%), Scotland (8%), Northern Ireland (4%) and Wales (3%). Seventy nine per cent of respondents were consultants, with 13% representing training posts. Forty per cent of respondents held a professorship/clinical lead position. Respondents’ countries of origin included England, Scotland, Ireland, India, Wales, Malaysia, Pakistan and Sri Lanka. Overall, the mean emotion exhaustion (EE) score was 23.5, representing a moderate level of EE. The mean depersonalisation (DP) score was 8.2, representing a moderate level of DP. The mean personal achievement (PA) score was 17.1, representing high levels of PA. Fifteen per cent (n=86) reported self-medication with non-prescription drugs or alcohol to combat signs and symptoms of burnout. Eight per cent (n=46) sought professional help for symptoms of burnout. Eighty per cent of respondents (n=460) felt that burnout should be evaluated amongst members of the ISU/BAUS, and sixty per cent (n=345) would avail of counseling if provided. This is the first study to address the issue of burnout across two separate health systems in the UK and Ireland. This study has demonstrated previously un-described high levels of burnout characterized by emotional exhaustion and depersonalization, with associated significant levels of self-medication amongst a male-predominant cohort. Burnout was attributed to non-surgical administrative/institutional factors, with the majority of respondents reporting support for staff evaluation and the provision of counseling services. This pilot study lends itself to the creation of risk stratification for urologists, and an opportunity to provide educational resources, training/development programs, and collegial and administrative support pathways.

    ABSTRACT: Background: Large annual scientific meetings such as the American Urological Association (AUA) and the European Association of Urology (EUA) have abstract conversion rates into publication of 37%−48%. There are no data on the conversion rates from national meetings of smaller European countries. Our objective was to present the conversion rates and manuscript characteristics of the Irish Society of Urology (ISU) annual meeting over a seven-year period (2005-2011), and to demonstrate the value, viability and sustainability of such a meeting as a model for other small national research programmes.

    ABSTRACT: To evaluate the accessibility, usability, reliability and readability of Internet information regarding transrectal ultrasound (TRUS) guided biopsy of the prostate. The terms "prostate biopsy", "TRUS biopsy" and "transrectal ultrasound guided biopsy of the prostate" were separately entered into the each of the top 5 most accessed Internet search engines. Websites were evaluated for accessibility, usability and reliability using the LIDA tool - a validated tool for the assessment of health related websites. Website readability was assessed using the Flesch Reading Ease Score and the Flesch Kincaid Grade Level. Following the application of exclusion criteria, 82 unique websites were analyzed. There was a significant difference in scores depending on authorship categories (p ≤ 0.001), with health related charity websites scoring highest (mean 122.29 ± 13.98) and non-academic affiliated institution websites scoring lowest (mean 87 ± 19.76). The presence of advertisements on a website was associated with a lower mean overall LIDA tool score (p = 0.024). Only a single website adhered to the National Institutes for Health recommendations on readability. This study demonstrates variability in the quality of information available to Internet users regarding TRUS biopsies. Collaboration of website design and clinical acumen are necessary to develop appropriate websites for patient benefit.

    ABSTRACT: Social media is the interaction among people in which they create, share or exchange information and ideas in virtual communities and web-based networks. This year, the Irish Society of Urology (ISU) expanded its involvement in social media with a preregistered Twitter hashtag (#ISU14) for the annual meeting. The aim of this study was to highlight the use of Twitter at an annual national meeting held in 2014. The Symplur healthcare analytics website was used to prospectively examine traffic related to the 2014 ISU Annual Meeting. This feature was used to generate statistics for the number of impressions, unique tweets (excluding retweets) and distinct contributors who used the indexing hashtag #ISU14. Individual tweets were assessed using the conference hashtag on the Twitter website. The total number of attendees at the conference was 119, and 99 individuals participated in Twitter using the conference hashtag (#ISU14). 31 % of attendees participated in tweeting at the conference. Over the course of the conference, a total of 798 unique tweets were generated, creating over 665,000 impressions in cyberspace. 590 (73.9 %) tweets were generated from attendees at the conference, while 26.1 % of tweets were from virtual followers. 702 (87.9 %) tweets were from urologists and 439 (55 %) tweets were of scientific nature. Tweet activity peaked during the guest lectures on both days. Twitter use at the ISU has been shown to facilitate interaction between delegates and allows users to follow as well as participate from afar.

    ABSTRACT: Renal artery aneurysms (RAA) are the second most common visceral artery aneurysm. In cases of rupture they pose a significant and emergent surgical challenge. Extracorporeal arterial reconstruction and autotransplantation is often necessary in certain complex cases that are not amenable to aneurysm repair in vivo. We report a case of a 35 year old female with a RAA in a solitary functioning kidney, requiring ex vivo reconstruction and autotransplantation to the iliac vessels.

    ABSTRACT: PURPOSE To assess the value of PIRADs scoring in predicting positive biopsy in patients with previous negative biopsy and elevated PSA, where the repeat biopsy is MR directed, trans-rectal ultrasound guided. METHOD AND MATERIALS HIPAA compliant, IRB approved study. 52 patients (mean age 64 years, range 52-76), with previous negative prostate biopsy and elevated PSA (mean =14.4 , range =7-34.4 ) underwent combined targeted and 12 sample sectoral biopsy over a 14 month period. Each patient’s MRI was retrospectively reviewed, blinded to biopsy result and each area of abnormality on MRI was scored according to PIRADs scheme, with separate T2, DWI, and overall scores per lesion. RESULTS Positive biopsy was obtained in 24/52 patients (overall yield of 46%). Predictive values based on most suspicious lesion overall per patient. PIRADs scores 1-5 (clinically significant cancer highly unlikely, unlikely, equivocal, likely, highly likely respectively). The positive predictive values of T2 PIRADS scores of 1,2,3,4 and 5 were,0, 33,33, 58 and 100% respectively. The positive predictive value of DWI PIRADS score of 1,2,3,4 and 5, was 0,N/A(no scores of 2), 0, 42 and 57% respectively. Only patients with overall score of 3-5 were biopsied, the positive predictive value of overall PIRADs score of 3, 4, 5 was 14, 57 and 100% respectively. CONCLUSION PIRADs provides a useful framework for reporting likelihood of prostate cancer, facilitating communication and guiding expectation of clinicians and patients in the setting of MRI assessment for occult prostate cancer and targeted biopsy. CLINICAL RELEVANCE/APPLICATION In patients with raised PSA and previous negative prostate biopy, the use of MRI can help target repeat biopsy and predict the likelihood of a positive result.

    ABSTRACT: To identify the incidence and features of significant incidental findings discussed at our departmental multidisciplinary team meeting (MDM). The improved quality of radiological imaging has resulted in increased rates of incidental findings. Although some may be trivial, many have clinical significance and early diagnosis and treatment may be beneficial. A retrospective analysis was performed of all cases discussed at the MDM between January 2012 and February 2013. Cases were divided into two groups - Group 1 consisted of patients whose initial imaging was performed for a urological presentation which resulted in a synchronous finding; Group 2 consisted of patients who were referred with a synchronous urological finding for discussion following investigation of an initial benign urological condition or a non-urological condition. 696 patients were discussed at 53 MDMs. 109 (15.7%) patients had incidental findings. 61 (56%) of these were in Group 1. 16 (26.2%) were synchronous malignant diagnoses, 25 (41%) were benign and 20 (32.8%) were indeterminate. 48 (44%) patients in Group 2 - 40 (83.3%) were renal in origin and 30 (75%) of these proceeded to surgery. The median tumour size was 3.2 cm (Range: 1.2 cm-10 cm). One patient had radio-frequency ablation. Two were referred for palliative care. Seven patients are under ongoing surveillance - the median size of these lesions is 3.6 cm (Range: 2.1 cm-8.3 cm). A substantial workload is generated from the investigation of incidental findings discussed at MDM - these now represent the majority of the caseload for renal cancer surgery.

    ABSTRACT: Bowel preparation was established as part of the pre-operative course for patients undergoing ileal conduit formation since the late 1970's. Rationales for its use include reduction in infection and wound complications, technically easier anastomosis and earlier return to bowel function. However, recent reports have challenged this practice. Traditionally antibiotics were also administered for several days prior to surgery with the assumption that bacterial load was reduced. Modification of antibiotic protocols resulted from evidence-based findings. Furthermore, publications emphasizing the benefit of Enhanced Recovery Protocols/Programmes (ERP) have become contemporary. An online multiple-choice questionnaire (via Monkey Survey(®)) was administered to all consultant urologists in Ireland. This national cross-sectional study evaluated the use of bowel preparation and antibiotic prophylaxis prior to urinary diversion. In addition, we also assessed consultant urologists' awareness of ERP and their views on the introduction and implementation of such a national program. Of the 41 consultant urologists surveyed, 80.4% (n = 33) responded. 63.6% routinely used bowel preparation. Klean Prep(®) was the most commonly used bowel preparation. 80.9% of urologists admit their patient's one-day pre-operatively for bowel preparation, with 87.8% using antibiotic prophylaxis at anesthesia induction, and 18.1% continuing the antibiotics for 24-48 h post-operatively. Although 74% of consultants are aware of ERP, only 66.6% are in favor of their national implementation. The majority of Irish urologists use bowel preparation prior to ileal conduit formation. Substantial recent evidence has emerged showing no difference in infective complications or anastomotic leakage when bowel preparation was not used. National guidelines would be beneficial regarding the use of bowel preparation, antibiotic prophylaxis and ERP for urinary diversion surgery.

    ABSTRACT: PURPOSE: There is growing conflict in the literature describing the effect of delayed treatment on outcomes following radical prostatectomy. There is also evidence to suggest progression of low-risk prostate cancer to develop higher grades and volumes of prostate cancer during active surveillance. It is unknown as to what affect a delay in referral of those men with abnormal screened-PSA levels have on subsequent Gleason grade. METHODS: We identified 350 men through our rapid access prostate clinic who underwent TRUS biopsy for abnormal age-related PSA and/or abnormal clinical examination. Clinicopathological findings were compared for those with positive versus negative TRUS biopsies, and for those with initial delays in referral (<12 months, 12-18 months, and >18 months). We used ANOVA and Student's t-tests amongst other statistical tools to examine significance of clinical findings. RESULTS: Of the 350 men who underwent TRUS biopsy, those with a delay in referral of 12 months or more were significantly associated with higher PSA titers, clinically palpable disease and likelihood of diagnosis with prostate cancer. A delay of 18 months or more led to a significantly higher risk of being diagnosed with a leading grade 4 prostate cancer, which was further supported using PSA velocity as a diagnostic tool (change >0.4 ng/ml/year). CONCLUSION: We recommend that repeated asymptomatic abnormal age-related PSA readings and/or abnormal clinical examination in the screened population be referred without delay to a urologist for further assessment, enrolment into an active surveillance program or definitive subsequent treatment.

    ABSTRACT: Fracture of the penis is a rare urological emergency which occurs as a result of abrupt trauma to an erect penis. There is paucity of data regarding long-term sexual function or erectile potency following fracture of the penis. The aim of this study is to objectively assess the overall sexual function following fracture of the penis. A retrospective analysis of 21 penile fractures was performed. A voluntary telephone questionnaire was performed to assess long term outcomes using three validated questionnaires-the Erection Hardness Grading Scale, the International Index of Erectile Function (IIEF-5) and the Brief Male Sexual Function inventory (BMSFI). The mean age was 33.1 years (range: 19-63). The median follow up was 46 months (range: 3-144). All fractures were a result of sexual misadventure and all were surgically repaired. There were two concomitant urethral injuries. Seventeen patients were contactable. Fourteen patients demonstrated no evidence of erectile dysfunction (ED) (IIEF-5>22), 1 patient reported symptoms of mild ED (IIEF-5, 17-21) and one patient reported mild to moderate ED (IIEF-5, 12-16). No patients reported insufficient erection for penetration (EHGS: 1 or 2). Regarding the overall BMSFI, 13 (83%) patients were mostly satisfied or very satisfied with their sex life within the previous month. In a small surgical series of men with penile fracture managed within a short time frame from presentation, we demonstrate erectile potency is maintained. Long-term overall sexual satisfaction is promising.

    ABSTRACT: Abstract Spontaneous abscess of the corpus cavernosum is an extremely rare presentation. This is the first documented case of corpus cavernosal abscess caused exclusively by organisms from the Streptococcus milleri group, which have previously been described as being associated with abscess formation. This report outlines the case of a 56-year-old alcoholic male with no risk factors who presented with an 8-day history of penile pain, swelling and sepsis. A diagnosis of abscess of the right corpus cavernosum was confirmed by magnetic resonance imaging. Management required intravenous antibiotics, penile exploration, incision and drainage. Streptococcus constellatus and Streptococcus intermedius were isolated. The aetiology, diagnosis, management and microbiology of this unusual presentation are discussed, and the few previously documented cases of abscess of the corpus cavernosum are reviewed.

    ABSTRACT: BACKGROUND: Recent evidence has suggested that the introduction of rapid access prostate cancer programs has led to a more streamlined pathway for patients, and was designed to ultimately reduce referral delays AIMS: To identify the initial impact of the introduction of the rapid access prostate clinic on Gleason grading within the prostate cancer cohort, as well as the impact of distance from a tertiary referral center on subsequent Gleason grading METHODS: A prospective database was maintained from those men attended the rapid access prostate clinic in St. Vincent's University Hospital. Data relating to demographics, biopsy results, retrospective PSA readings, and subsequent treatment pathways were all recorded and analyzed. Statistical significance was taken at p < 0.05 RESULTS: Prospective data from the rapid access prostate clinic illustrated similar results in patient demographics, Gleason grade and choice of treatment outcomes to other published institutions, however, for the first time demonstrate emerging evidence of the effect of the rapid access prostate clinic leading to a downward shift in Gleason grade over a 2-year period, as well as data showing an inverse correlation between leading Gleason grade and distance from our tertiary referral center CONCLUSION: These results suggest that the introduction of the rapid access prostate clinic has initially begun to demonstrate an initial downgrading in Gleason scoring patterns. Our data also reflects a poorer Gleason score in those patients living further away from the rapid access prostate clinic. This may be in part attributed to a surge in referrals of those patients previously managed outside a tertiary institution, and suggests that patients should undergo prompt referral following suspicion for prostate cancer.

    ABSTRACT: Urethral duplication is a rare congenital anomaly with less than 200 cases reported. It predominantly occurs in males and is nearly always diagnosed in childhood or adolescence. It is defined as a complete second passage from the bladder to the dorsum of the penis or as an accessory pathway that ends blindly on the dorsal or ventral surface. We present the case of a 54-year-old patient with incomplete urethral duplication. Urethral duplication commonly occurs in the sagittal plane with one urethral channel lying dorsal to the other. Symptoms vary from completely asymptomatic to urinary incontinence which can lead to a mucopurulent discharge from a low grade urinary tract infection. Other symptoms include double stream (most common complaint) and intermittent urinary discharge.

    ABSTRACT: Extracorporeal shock-wave lithotripsy (ESWL) is a relatively new technological adjunct in the treatment of renal calculi, but availability is limited. The aim of this study was to assess the outcome of ureteroscopic procedures in a unit without on-site ESWL facility. A retrospective study of all cases of ureteric calculi presenting to this hospital during the period 1991 to 1997 was performed. One hundred and thirty five patients with a mean age of 46.8 years were evaluated. Ninety-four (69.5%) had their stone successfully manipulated and/or extracted at ureteroscopy. Using strict criteria, 41 patients (30.5%) had failed ureteroscopies. Fourteen (10.4%) suffered complications related to their ureteroscopy, thirteen had their complications treated conservatively and three (2.3%) needed open procedures. Ureteroscopy has a high success rate and low morbidity. We continue to advocate ureteroscopy in the initial management of ureteric calculi.

    ABSTRACT: Although well described, there is limited published data related to management on the coexistence of prostate and rectal cancer. The aim of this study was to describe a single institution's experience with this and propose a treatment algorithm based on the best available evidence. From 2000 to 2011, a retrospective review of institutional databases was performed to identify patients with synchronous prostate and rectal cancers where the rectal cancer lay in the lower two thirds of the rectum. Operative and non-operative outcomes were analysed and a management algorithm is proposed. Twelve patients with prostate and rectal cancer were identified. Three were metachronous diagnoses (>3-month time interval) and nine were synchronous diagnoses. In the synchronous group, four had metastatic disease at presentation and were treated symptomatically, while five were treated with curative intent. Treatment included pelvic radiotherapy (74 Gy) followed by pelvic exenteration (three) and watchful waiting for rectal cancer (one). The remaining patient had a prostatectomy, long-course chemoradiotherapy and anterior resection. There were no operative mortalities and acceptable morbidity. Three remain alive with two patients disease-free. Synchronous detection of prostate cancer and cancer of the lower two thirds of the rectum is uncommon, but likely to increase with rigorous preoperative staging of rectal cancer and increased awareness of the potential for synchronous disease. Treatment must be individualized based on the stage of the individual cancers taking into account the options for both cancers including EBRT (both), surgery (both), hormonal therapy (prostate), surgery (both) and watchful waiting (both).
