The Inclusion of Practical Urology Skills in Intern Induction: A Pilot Programme.

Introduction Intern is the first postgraduate year of training and gives interns the opportunity to practice skills in real-life settings. We aim to examine the undergraduate exposure to urology across all Irish Medical Schools and assess the impact of a mandatory urology training skills session delivered during induction on the preparedness of interns ahead of starting their intern year. Methods In July 2020 all interns mandated to attend the Dublin/Mid-Leinster (DML) network intern induction underwent a 120-minute urology teaching session. The session comprised of formal teaching, followed by practical training and an informal question and answer session. All interns were asked to complete a survey before and after the session that examined undergraduate urology exposure and confidence around practical skills. Results All interns (n=74) who attended induction completed the survey. Less than half [43% (n=32]) reported a compulsory urology placement in medical school and 57% (n=42) reported previous practical training sessions in urology. There was low level of confidence in the management of urological scenarios with only 45 % (n = 33) reporting confidence in the management of urosepsis and 26 % (n = 19) in the insertion of a male catheter. There was a significant increase in self-reported confidence following the teaching session with 78 % (n = 58) interns reporting confidence in the management of urosepsis and 81 % (n = 60) in the insertion of a male catheter. Conclusion To ensure best patient care interns need to be trained in the management of common urology presentations, but our results suggest the current undergraduate curriculum is not sufficient. A dedicated theory and practical urology teaching session during intern induction was able to improve self-reported confidence and better prepare interns. Therefore we support inclusion of practical urology skills session in network intern induction.

The role of T-lymphocytes in neuropathic pain initiation, development of chronicity and treatment.

Ongoing research has strongly suggested the role the immune system plays in the pathogenesis of neuropathic pain. T cells appear to be one of the main regulators of the immune system with many mediators appearing to promote or suppress pain resolution. Limited effective therapies are available for treatment of neuropathic pain. Treatments available appear to modulate specific T cell with altered ratios present 3 months post treatment and parallels clinical improvement. This further supports the neuro-immune basis for neuropathic pain chronicity. Identification of novel immune mediators involved in pain development may suggest new target areas in treatment.

The Management of Incidental Prostate Cancer Following TURP

Aims The aim of this study was to assess the incidence, management and outcomes of incidentally diagnosed prostate cancer following TURP. Methods A retrospective review was performed using the histopathological departments' database of all patients who underwent a TURP across two university teaching hospitals over a ten year period. Results During the study period, a total of 826 patients underwent a TURP. 72 (10.3%) had an incidental diagnosis of CaP following TURP. 46 (63.9%) were managed expectantly while 26 (36.1%) underwent active treatment. Overall mortality was 29.2% (n=21) while cancer specific mortality was 6.9% (n=5). All these patients were in the hormonal treatment sub-group. Conclusion Our study demonstrates an expectant approach is favourable in low risk disease. Curative treatment does need to be considered for younger patients with a long life expectancy or patients with higher risk disease.

Iatrogenic Bowel Injury at Exchange of Supra-Pubic Catheter

Suprapubic catheter insertion and exchange is a common urological procedure, but it is not without risks and complications. While bowel perforation is a recognised complication at suprapubic catheter insertion, it is not commonly reported at suprapubic catheter exchange. We report our experience of recognition, diagnosis and subsequent successful management of the most important complication related to suprapubic catheters.

Prospective evaluation of a virtual urology outpatient clinic.

BACKGROUND: Outpatient department (OPD) clinics account for a significant proportion of healthcare expenditure. We report on a pilot study of a virtual outpatient clinic (VC) for urology patients as an alternative to a general urology clinic review. AIMS: The study aims to assess the safety and cost-effectiveness of a virtual clinic as an alternative to general OPD review. METHODS: A prospective study performed between March 2015 and December 2015 investigated the effectiveness of a VC in our institution. Eligible patients were recruited from general urology outpatient visits, from medical team members and from general practitioners (GP). Data recorded on each VC review included patient demographics, indication for referral to VC, outcome of VC and method of communication with the patient and their GP after the VC. RESULTS: Three hundred eighty-five patients were registered for the VC. Indications for referral included review of imaging results (n = 136), doctor or patient query (n = 112) and review of laboratory results (n = 67). Outcomes after VC review included general OPD follow-up (n = 134), discharge from urology care (n = 39), referral for urological intervention (n = 29) and referral for radiological investigation (n = 23). VC review prevented 217 OPD clinic visits, saved €17,360 and provided a failsafe mechanism for reviewing investigation results. Two patients booked for OPD review following VC review did not receive appointments. CONCLUSIONS: Virtual clinic is a safe and cost-effective alternative to general OPD review in appropriately selected patients.

The Hidden Burden of Outpatient Repeat PSA Testing in a Prospective Cohort.

PSA testing is widespread throughout Europe for diagnostic purposes and follow up. We performed a prospective outpatient cohort study of 250 men (2013-2015) in two hospital sites. Included were those men being followed up by urology with PSA blood testing. First appointments and those men in whom non-PSA tests were ordered by urology were excluded. The median age was 67.2yrs (46-88). Eighty-one point two percent of samples had a combination of 21 different serology tests at an added cost of >€18,000. Abnormal serology resulted in 53 referrals. Twenty-six-six percent of correspondence referenced abnormal serology other than PSA. Follow up of non-PSA test results poses a challenge in an outpatient setting with failure to appropriately follow-up on abnormal results, increased costs, and medico-legal implications. There is currently no Irish legislature in place to safeguard hospital physicians. This study quantifies the levels of expenditure, resources and risk associated with ambulant PSA testing.

The effect of Rapid Access Prostate Clinics on the outcomes of Gleason 7 prostate cancer: does earlier diagnosis lead to better outcomes?

INTRODUCTION: Rapid Access Prostate Clinics (RAPC) were introduced in Ireland by the National Cancer Control Programme bringing about expedited referral pathways and increased detection rates of prostate cancer. Lower Gleason (G) grade at diagnosis due to RAPC has been previously reported but grade at prostatectomy has not been assessed. The aim of this study was to assess the impact of RAPC on the outcomes of patients with G7 disease on radical prostatectomy (RP). METHODS: A retrospective analysis was carried out of all RPs performed over a 9-year period (2006-2014). Outcomes for G7 prostatectomies were compared before and after the introduction of the RAPC, with a further sub-analysis of G4 + 3 versus G3 + 4. The primary outcome was biochemical recurrence (BCR). Other outcomes were adjuvant/salvage radiotherapy, extra prostatic extension, positive surgical margins, seminal vesicle involvement and tumour stage. RESULTS: In total, 240 RPs were performed with 167 cases graded G7 (70 graded G4 + 3 and 97 graded G3 + 4). Since the introduction of RAPC the proportion of G4 + 3 compared to G3 + 4 has increased from 37.9 to 42%. There was no statistical difference in outcomes for G4 + 3 treated before and after the introduction of RAPC. G4 + 3 was associated with higher rates of BCR (24.4 vs. 0%, p < 0.0001, radiotherapy (41.1 vs. 4.8%, p < 0.0001) and worse histological features than G3 + 4. CONCLUSION: Despite the benefits in diagnosis of prostate cancer brought about by RAPC in Ireland, this has not translated to a lower grade for surgically treated patients. There has been no improvement in outcomes especially for higher grade G4 + 3 disease.

Development and evaluation of a centralised computerised registry for ureteric stents: completing the audit cycle.

INTRODUCTION: A forgotten ureteric stent may result in severe renal impairment leading to nephrectomy. AIM: To compare the effectiveness of a centralised computerised registry for monitoring ureteric stent activity with a previously established theatre stent logbook system. METHODS: This prospective audit was performed in two 9-monthly intervals. During the first interval, insertion/removal of a ureteric stent was documented in a specific theatre stent logbook. In the second interval, an electronic centralised computerised registry was developed to document insertion/removal of a ureteric stent onto an accessible hospital server. A computerised traffic-light system was also developed to identify patients with an indwelling stent for >3 months. The primary outcome variable was the number of prolonged indwelling ureteric stents in both groups. RESULTS: During the first time interval, 188 ureteric stents were inserted and 182 (96%) were removed or changed. Six (4%) patients underwent insertion of a ureteric stent for a prolonged period of time (>6 months). This subgroup required complex endourological intervention for stent removal due to encrustation. During the second time interval, 157 ureteric stents were inserted and all patients had their stent removed or changed within 6 months. No patients in this group were lost to follow-up. CONCLUSION: This study demonstrates that a centralised computerised ureteric stent registry is superior to a conventional logbook for monitoring ureteric stent activity. We propose the introduction a centralised nationalised ureteric stent registry for eliminating the potential for prolonged or forgotten ureteric stents.

Procoagulant activity in gynaecological cancer patients; the effect of surgery and chemotherapy.

BACKGROUND: Gynaecological cancers are associated with high rates of venous thromboembolism (VTE). Studies on ambulatory cancer patients do not support thromboprophylaxis during chemotherapy. Approximately 6-7% of gynaecological cancer patients suffer a postoperative VTE despite Low Molecular Weight Heparin prophylaxis (LMWH). Large cancer studies have shown that Calibrated Automated Thrombogram (CAT) and Microparticles (MP) assays may be useful in predicting VTE but data on gynaecological cancer patients is scarce. OBJECTIVE: Our objective was to identify whether the CAT assay and MP functional assays have potential as biomarkers predictive of VTE in gynaecological cancer patients. PATIENTS AND METHODS: Gynaecological cancer patients were investigated before surgery (n=146) and at 5, 14 and 42days post-surgery (n=78). Fourteen additional patients were investigated before chemotherapy and after 3 and 6 cycles of therapy. Thrombin generation was measured before and after addition of thrombomodulin. RESULTS: Patients with clear cell cancer (CCC) of the ovary and patients with endometrial cancer had higher ETP and peak thrombin compared with patients with benign disease. Patients who developed VTE (n=8) following surgery had enhanced thrombin generation prior to surgery which persisted during the post-operative period despite LMWH prophylaxis. Both neoadjuvant and adjuvant chemotherapy showed increased thrombin generation following addition of thrombomodulin. There were no differences in MP levels during the study. CONCLUSIONS: CAT assay shows potential as a promising biomarker for the prediction of VTE in gynaecological cancer patients. The identification of high risk patients combined with individualised LMWH prophylaxis might reduce VTE in this high risk group.

Predictive value of PI-RADS classification in MRI-directed transrectal ultrasound guided prostate biopsy.

AIM: To correlate the results of transrectal ultrasound (TRUS)-guided targeted prostate biopsies (performed in the setting of at least one previous negative biopsy) with the Prostate Imaging Reporting and Data System (PI-RADS). MATERIAL AND METHODS: Fifty-two patients (mean age 64 years, range 52-76 years), with previous negative prostate biopsy underwent magnetic resonance imaging (MRI)-directed TRUS-guided targeted and sectoral biopsy. A retrospective review of MRI examinations was carried out, blinded to biopsy results. PI-RADS scores (T2, diffusion-weighted imaging [DWI] and overall) were assigned on a per lesion basis, and localised to sextants. The scores were correlated with biopsy results, and the positive predictive values (PPV) of PIRADS scores for positive biopsies were calculated. RESULTS: Overall, biopsies were positive in 23/52 (44.2%) patients. Eighty-one areas were targeted in 52 patients. On a per lesion basis, there was significant correlation between positive targeted biopsy and both T2 and overall PI-RADS score (p<0.001). The correlation between biopsy and DWI score was significant for peripheral zone tumours only, not for transitional zone tumours. The PPV of overall PI-RADS scores of 3, 4, and 5 were 10.6%, 44%, and 100%, respectively. The PPV of T2 PI-RADS scores of 3, 4, and 5 were 19.6%, 60%, and 100%, respectively. The PPV of DWI PI-RADS scores of 3, 4, and 5 were 50%, 27.3%, and 33%, respectively. When transitional tumours were excluded, the PPV of DWI PI-RADS 3, 4, and 5 were 40%, 43%, and 78%. CONCLUSION: The PIRADS score provides an effective framework for determining the likelihood of prostate cancer on MRI. The DWI PI-RADS score correlates well with the presence of peripheral zone tumour on targeted biopsy, but not with transitional zone tumours.

Predicting prostate cancer: analysing the clinical efficacy of prostate cancer risk calculators in a referral population.

BACKGROUND: The decision to proceed to biopsy for the diagnosis of prostate cancer in clinical practice is a difficult one. Prostate cancer risk calculators allow for a systematic approach to the use of patient information to predict a patient's likelihood of prostate cancer. AIMS: In this paper, we validate the two leading prostate cancer risk calculators, the prostate cancer prevention trial (PCPT) and the European Randomized Study of Screening for Prostate Cancer (ERSPC) in an Irish population. METHODS: Data were collected for 337 men referred to one tertiary referral center in Ireland. Calibration analysis, ROC analysis and decision curve analysis were undertaken to ascertain the performance of the PCPT and the ERSPC risk calculators in this cohort. RESULTS: Of 337 consecutive biopsies, cancer was subsequently diagnosed in 146 men (43 %), 98 (67 %) of which were high grade. The AUC for the PCPT and ERSPC risk calculators were 0.68 and 0.66, respectively for the prediction of prostate cancer. Each calculator was sufficiently calibrated in this cohort. Decision curve analysis demonstrated a net benefit via the use of the PCPT and ERSPC risk calculators in the diagnosis of prostate cancer. CONCLUSIONS: The PCPT and ERSPC risk calculators achieve a statistically significant prediction of prostate cancer in this Irish population. This study provides external validation for these calculators, and therefore these tools can be used to aid in clinical decision making.

Peri-operative management in urinary diversion surgery: A time for change?

INTRODUCTION: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

A Narrative Review on the Pathophysiology and Management for Radiation Cystitis.

Radiation cystitis is a recognised complication of pelvic radiotherapy. Incidence of radiation cystitis ranges from 23 to 80% and the incidence of severe haematuria ranges from 5 to 8%. High quality data on management strategies for radiation cystitis is sparse. Treatment modalities are subclassified into systemic therapies, intravesical therapies, and hyperbaric oxygen and interventional procedures. Short-term cure rates range from 76 to 95% for hyperbaric oxygen therapy and interventional procedures. Adverse effects of these treatment strategies are acceptable. Ultimately, most patients require multimodal treatment for curative purposes. Large randomised trials exploring emergent management strategies are required in order to strengthen evidence-based treatment strategies. Urologists encounter radiation cystitis commonly and should be familiar with diagnostic modalities and treatment strategies.

Incidentalology: A developing urological sub-specialty.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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). CONCLUSION: 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.

Emerging evidence for Gleason grade migration and distance impact in prostate cancer? An analysis of the rapid access prostate clinic in a tertiary referral center: St. Vincent's University Hospital, Dublin (2009-2011).

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.

Pregnancy in women with Type 1 and Type 2 diabetes in Dublin.

INTRODUCTION: The Confidential Enquiry into Maternal and Child Health (CEMACH) reported outcomes of pregnancies in women with pre-gestational diabetes (PGDM) in the UK (n = 3,733). This study aimed to compare CEMACH outcomes with PGDM pregnancies in Dublin. METHODS: Retrospective chart review of all PGDM pregnancies. Comparison to CEMACH are shown in brackets. RESULTS: One hundred and ten PGDM women delivered in Dublin. Thirty (27%) had T2 diabetes (vs. 27%). Fifty-nine (53%) women had a booking HbA1c less than 7% (vs. 66%). Nineteen women (17.3%) had a first trimester miscarriage (vs. 8.5%). Of the 91 remaining women, 71 (78%) women underwent induction of labour (vs. 38.9%). Fifty-four women (59.3%) were delivered by caesarean section (vs. 67.4%). Two infants (2.1%) were macrosomic (vs. 5.7%). There was one intrauterine death (0.1 vs. 0.6%) and no maternal deaths (vs. five). CONCLUSION: These results serve to underline the continued importance of multidisciplinary care for pregnant women with diabetes.

Carcinosarcoma of the penis.

BACKGROUND: Carcinosarcoma of the penis is extremely rare and little is known about its biological behaviour. AIMS: We report the second such case and discuss its histological categorisation and biological behaviour. METHODS: A total penectomy with perineal urethrostomy was performed without lymphadenectomy in an 83-year old presenting with a fungating penile mass. RESULTS: Microscopy of the gross specimen showed a biphasic tumour with both squamous and spindle cell elements. Immunohistochemical staining for epithelial markers showed positivity in the squamous cell elements but was uniformly negative in the spindle component. Immunohistochemistry of the spindle cell element demonstrated mesenchymal markers. The patient refused further treatment and follow up but presented at 26 months with inguinal lymphadenopathy. Biopsy confirmed squamous cell carcinoma metastasis consistent with penile origin. The patient refused further surgery and received pelvic irradiation. He died 6 months later. CONCLUSIONS: This case illustrates the biological behaviour of this rare tumour.
