In the era of minimally invasive surgery (MIS), parenchyma-preserving liver resections are gaining prominence with the potential to offer improved perioperative outcomes without compromising oncological safety. The surgeon learning curve remains challenging, and simulation plays a key role in surgical training. Existing simulation models can be limited by suboptimal fidelity and high cost. We describe a novel, reproducible, high-fidelity, low-cost liver metastases model using porcine livers from adult Landrace pigs, with porcine perinephric fat used to simulate subcapsular metastases. This model was then utilised in a training session for surgical trainees performing robotic parenchyma-preserving surgery (PPS) under the guidance of expert robotic surgeons, with feedback being recorded. Trainees rated the model highly on its fidelity to human liver simulation (median score 9), tissue handling (median score 8), and overall usefulness (median score 9). Tissue handling was felt to simulate in vivo liver resection closely, while suggestions for improvement included adding simulated blood flow. This is a novel, low-cost, high-fidelity simulation model of liver metastases with high acceptability to surgical trainees, which could be readily adopted by other training centres.

Introduction: Laparoscopic nephrectomy has gained widespread acceptance as a treatment for both benign and malignant conditions and is becoming increasingly popular in Irish hospitals. We report a single surgeon, single centre experience with 20 consecutive laparoscopic nephrectomies comparing them to 20 open cases performed prior to the establishment of a laparoscopic service. Methodology: A retrospective comparative analysis was carried out over an 18 month period. Transperitoneal approach was used in the laparoscopic group with renal vessels divided using an Endo GIA® stapling device. Parameters examined included age, weight, indication, operative time, blood loss, tumour size, length of stay and analgesic requirements. Comparison was made with 20 open nephrectomies. Results: Mean age (p=0.26) and weight (p=0.08) were similar in both groups. Average tumour size was similar (4.98cm [range 2.8-9] in laparoscopic group versus 6.4cm [range 3-10], p=0.61). Mean operative blood loss was reduced in the laparoscopic group (65ml (range 50-200) versus 351ml (50-1740) (p=

Aims This study focuses on the assessment of patient reported outcome measures (PROMs) following an educational intervention by urological service providers. In the modern era, social media and search engines are used as educational tools for both patients and healthcare providers alike. The aim of the study was to assess patient satisfaction with kidney stone information, through the viewing of a novel kidney stone educational video. Methods A prospective quality improvement study was conducted amongst patients admitted to our urology service with kidney stones undergoing emergency ureteroscopy using a patient satisfaction questionnaire. Results Patients reported increased satisfaction with overall information provided about kidney stone prevention after viewing the kidney stone educational video (4.8 vs 4 p=0.01). They also reported increased satisfaction with information provided about diet and lifestyle modification (4.5 vs3 p=0.02) (4.6 vs 3 p=0.02), information and demonstration on stent removal 4.8 vs 3.17 p=0.029), information on stent pain (4.7 vs 2.6 P=0.016) and availability of educational information and resources after viewing the video (4.8 vs 2.83 p=0.017). There were 17 patients in total included for statistical analysis. Conclusion Patient satisfaction with traditional patient education regarding kidney stones can be further strengthened through the use of a concise, informative, and readily accessible patient education video during and after point of care., Competing Interests: The authors have no conflicts of interest to declare.

Ureteric stents are frequently inserted post endourological procedures. However, subsequent endoscopic stent removal requires a second procedure for the patient and the availability of necessary resources. Longer duration of indwelling stents can lead to increased risk of symptoms and complications. The use of magnetic stents removed with a magnetic retrieval device (BlackStar©), offers an alternative which obviates the need for cystoscopy. We assessed the outcomes for this novel method of stent removal in our institution. A retrospective analysis was performed of all patients undergoing magnetic stent insertion and subsequent removal in a nurse-led clinic over a nine-month period. Patients were followed up with a prospective validated Ureteral Stent Symptoms Questionnaire (USSQ)3. A cost analysis was also performed. In total, 59 patients were treated using magnetic stents. The complication rate was low (6.7%). The median duration of indwelling stent was 5.8 days (range 1-11 days). Patients reported haematuria and lower urinary tract symptoms but >90% experienced no functional impairment with minimal days of employment lost (mean 0.75 days). All patients reported satisfaction with nurse-led stent removal and 97% were happy to have stents removed via this method in the future. The total financial savings were estimated at €47,790 over this period. Nurse-led removal of magnetic stents is safe and well tolerated by patients and enables expedient stent removal. It also provides a significant cost benefit and frees up valuable endoscopic resources.

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., (Copyright © 2013 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

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., (Copyright © 2013 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Functional reconstruction of the human urinary bladder has been attempted by replacing defective bladder tissue with tissue-engineered xenogenic extracellular matrix (ECM) scaffolds. However, experimental studies that demonstrate the effects of implanted ECMs on important biomechanical properties such as total bladder capacity (TBC) and compliance (C) are lacking. In the current study, the effects of ECM scaffold surface area (SA) on TBC and C was assessed, ex vivo, in an ovine model (n=5). TBC and C were measured at pressures (P) of 5, 10, 15 and 20 mm Hg prior to performing a 3×3 cm (9 cm(2)) partial cystectomy defect. Equal-sized 3×3 cm (9 cm(2)) and larger 6×6 cm (36 cm(2)) urinary bladder matrix (UBM) scaffolds of porcine origin replaced the 3×3 cm cystectomy defect, and TBC and C were re-recorded for comparative analysis. The results showed that TBC decreased by 39.6%±0.005% (122.9 ml±15 ml, p<0.05) and C by 38.9%±0.51%, (ΔP=0-5mmHg, p<0.05) in ovine bladders reconstructed with 3×3 cm UBM scaffolds compared to their native values. It was also found that TBC increased by 25.6±0.64% (64.2 ml ± 8.8 ml, p>0.05) and C by 24.5±0.43% (ΔP=0-5mmHg, p>0.05) in the 6×6 cm UBM scaffold group compared to the 3×3 cm UBM scaffold group; however, these values were not statistically significant. The present work demonstrates that a fourfold increase in ECM scaffold SA relative to its intended defect does not lead to a significant improvement in TBC and C values., (Copyright © 2010 Elsevier Ltd.

The British Association of Urological Surgeons (BAUS) has recently recommended guidelines for the management of Lower Urinary Tract Sypmtoms by GPs outlining the indications for urological referral. We wished to assess the prescription of medical therapy by GPs in the referrals to our LUTS pre-assessment clinic. 115 consecutive patients were reviewed prospectively, over a three month period. Each patient was assessed for International Prostatic Symptom Score (IPSS) and Bother Score, uroflowometry with post void residual and whether medical therapy had been commenced (D-Blocker or 5-D-Reductase inhibitor). The majority of patients (75%) were classified with moderate symptoms. Only 10% of those with moderate symptoms and 5% of those with severe symptoms were commenced on medical therapy by their GP as recommended by the BAUS guidelines. Only 30 patients (26%) had completed an IPSS form with their GP. The majority of patients referred to our service for assessment of LUTS have at least moderate symptom severity and are not prescribed medical therapy by their GP. Further primary care education with greater emphasis on the BAUS LUTS algorithm prior to referral to an urologist should be encouraged.
