Time, cost and carbon-efficiency: a silver lining of COVID era virtual urology clinics?

INTRODUCTION: The COVID-19 pandemic has demanded radical changes in service delivery. Our centre adopted the use of outpatient telemedicine to reduce close-contact interactions between patients and staff. We hypothesised that incidental gains may be associated with this. We evaluated financial, practical and environmental implications of substituting virtual clinics (VCs) for in-person urology outpatient appointments. METHODS: VCs were studied over a 3-month period. Based on patient-reported 'usual mode of transport' to the hospital, travel distance, time, petrol and parking costs, and the carbon emissions avoided by virtue of remote consultations were calculated. The underlying symptom/diagnosis and the 'effectiveness' of the VC were evaluated. RESULTS: Of 1,016 scheduled consultations, 736 (72.44%) were conducted by VCs over the study period. VCs resulted in an agreed treatment plan in 98.4% of a representative patient sample. The use of VCs was associated with an overall travel distance saving for patients of 31,038 miles (49,951km) over 3 months, with an average round-trip journey of 93.8 miles (151km) avoided for each rural-dwelling patient and an average financial saving of £25.91 (€28.70) per rural-dwelling car traveller. An estimated 1,257.8 hours of patient time were saved by avoidance of travel and clinic waiting times. Based on car-travelling patients alone, a 6.07-tonne reduction in carbon emissions was achieved with the use of VCs. CONCLUSIONS: In appropriate clinical circumstances, VCs appear to provide efficiency across a number of domains. Future healthcare may involve offering outpatients the option of telemedicine as an alternative to physical attendance.

Long-term outcomes of en-bloc renal transplantation from paediatric donors into adult recipients.

INTRODUCTION: Transplant units are exploring strategies to increase the availability of donor kidneys. The use of en-bloc kidney transplantation (EBKT) from paediatric donors represents one potential solution. We present our long-term experience with paediatric EBKT among adult recipients. METHODS: Twenty-three paediatric to adult EBKTs were performed by the Irish National Kidney Transplant Service between 1990 and 2016. The primary outcome variable was long-term en-bloc allograft survival rate. Secondary outcome variables were incidence of allograft thrombosis, incidence of delayed graft function, overall patient survival and serum creatinine at most recent follow-up. Outcomes were compared to single kidney transplant recipients from the same time period. RESULTS: Mean donor age was 1.8 ± 0.97 years (range: 7 months to 3 years). Recipient age was 46 ± 12 years. Mean follow-up was 133 ± 64 months (range: 36-264). Overall graft survival was 100%, 91% and 80% after 1, 5 and 10 years respectively, compared to 92%, 79% and 61% in single kidney transplant recipients (p = 0.04). There were 5 cases of allograft failure, 3 due to death from unrelated causes. Median time to graft failure was 108 months (range: 36-172). Mean serum creatinine was 72.6 ± 21.6 µmol/l after the follow-up period. There were no cases of graft thrombosis or delayed graft function. Overall survival was 96.4%, 88.0%, 76.23% and 50.5% at 1, 5, 10 and 20 years respectively. CONCLUSION: En-bloc paediatric kidney transplantation is associated with excellent long-term allograft and patient survival and is a feasible strategy for increasing the transplant donor pool in carefully selected recipients.

The Predictive Ability of Pre-Operative Magnetic Resonance Imaging to Detect Pathological Outcomes in Prostate Cancer

Aims Accurate preoperative knowledge of tumour stage is important in preoperative planning at radical prostatectomy (RP). The aim of this study was to assess the predictive ability of multiparametric MRI for detecting pathological outcomes. Methods A retrospective review was performed of all patients who underwent RP over a 4 year period. Results Preoperative MRI was reported as showing T3 or T4 disease in 26(17.9%) out of 145 patients undergoing RP. Of these, 10(6.9%) had ECE (extra-capsular extension) and 1(0.7%) had SVI (seminal vesicle invasion) on final histology. The sensitivity and specificity of MRI for detecting ECE were 27.3% and 87.6%, respectively. The sensitivity and specificity of MRI for detecting SVI were 11.1% and 97.8%, respectively. The positive predictive values for determining ECE and SVI were 45.5% and 25%, respectively and negative predictive values were 75.9% and 94.4%. Conclusion MRI has good specificity but poor and heterogeneous sensitivity for predicting T3 disease in RP specimen.

The natural history of Leydig cell testicular tumours: an analysis of the National Cancer Registry.

BACKGROUND: Leydig cell tumour (LCT) of the testis is a rare histological subtype of stromal tumours, accounting for 1 to 3% of testicular neoplasms. The natural history of LCT is poorly understood. AIMS: The aim of this study was to assess the incidence and natural history of Leydig cell tumours (LCT) of the testes. METHODS: A search of the National Cancer Registry of Ireland database was performed regarding Leydig cell testicular tumours. Recurrence free survival (RFS) and disease-specific survival (DSS) were analysed. RESULTS: Between 1994 and 2013, 2755 new cases of testicular cancer were diagnosed in Ireland. Of these, 22 (0.79%) were Leydig cell tumours. Nineteen were invasive (stage T1) and three were in situ (stage Tis). One patient developed a local recurrence following an organ preserving procedure and underwent a completion orchidectomy 107 days after initial diagnosis. No further treatment was required. There have been no disease-specific deaths. The 1-, 3- and 5-year overall survival (OS) rates were 95.5, 88.2 and 73.3%, respectively. The 5-year disease-specific survival (DSS) was 100% and the 5-year recurrence free survival (RFS) was 93.3%. CONCLUSION: From the National Cancer Registry, LCT has been shown to be a rare subtype of testicular tumour. Due to the relatively favourable natural history, it may be possible to tailor less aggressive surveillance regimens in these patients.

Comparison of nomograms predicting lymph node invasion in patients undergoing radical prostatectomy for prostate cancer.

INTRODUCTION: The aim of this study was to compare the performance of preoperative risk nomograms or detecting lymph node invasion in a cohort of men undergoing radical prostatectomy (RP). METHODS: A retrospective analysis was performed on all men (n = 145) who underwent RP between 2012 and 2015. Preoperative data was inputted to the Memorial Sloan-Kettering Cancer Centre (MSKCC), Partin 2011 and Briganti nomograms and the University of California San Francisco- Centre of the Prostate Risk Assessment tool (UCSF-CAPRA). The risk of lymph node involvement (LNI) was calculated and compared to final histology. RESULTS: One hundred three (71%) men underwent a lymph node dissection at RP. Ten (9.7%) demonstrated LNI. The median nodal yield was 15 nodes, with no difference between those with LNI and those without (19.5 vs 14.5, p = 0.22).No patient classified as low risk on the UCSF-CAPRA score had evidence of LNI. In patients with LNI, no patient breached the 2% threshold for lymph node dissection (LND) on the MSKCC nomogram; four patients breached the 5% threshold on the Partin tables while three patients breached the 2.5% threshold for the Briganti nomogram. CONCLUSION: Nomograms produce useful information regarding risk of disease; however, they often have not been validated on different populations. Risk predictions need to be considered carefully and treatment decisions were made on a patient specific basis.

Post-Chemotherapy Retroperitoneal Lymph Node Dissection in Patients with Non-Seminomatous Germ Cell Tumour (NSGCT).

Diabetic retinopathy is a significant complication of diabetes, and the most common cause of blindness in people under the age of 65. The National Diabetic Retinal Screening Programme (Diabetic RetinaScreen) was established to detect sight threatening retinopathies. The purpose of this cross-sectional study is to determine the barriers to the uptake of Diabetic RetinaScreen, to investigate discrepancies in attendance, if any, between patients whose diabetes care is delivered in a large tertiary referral hospital out-patient setting or in general practice, and to evaluate general practitioner's satisfaction with the service. Older age (OR 1.023, 95% CI 1.001 to 1.046) and complications of diabetes, excluding ocular complications, (OR 2.741, 95% CI 1.158 to 6.489) were associated with increased attendance at Diabetic RetinaScreen. Online referral is now available and the preferred method of referral. Efforts to encourage younger patients who do not yet have complications of diabetes may be beneficial.

Post-chemotherapy retroperitoneal lymph node dissection in the management of metastatic testis cancer: the 16-year experience in an Irish setting.

INTRODUCTION: Post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) is an important tool in the management of advanced germ cell testis cancer, particularly non-seminoma. AIM: We present the 16-year experience with PC-RPLND in a single Irish tertiary referral centre, and compare our results to the major speciality centres worldwide. METHODOLOGY: All 78 patients undergoing PC-RPLND for the treatment of metastatic testis cancer between January 1996 and December 2011 were included. Medical records were reviewed and up to date follow-up obtained from primary referral centres, patient's GPs and individual patient interview. RESULTS: The mean age at diagnosis was 28.5 ± 7 years. Initial pathology included non-seminoma 62.8 %, seminoma 6.4 % and combined 19.2 %. All patients underwent pre-operative chemotherapy. The resection template utilised was bilateral infra-hilar in 29.5 %, unilateral infra-hilar in 46.2 % and supra-hilar in 20.5 %. Complete abdominal remission was achieved in all but one patient. Additional procedures were required in 38.5 % of patients (n = 30). Clavien Dindo grade three or four complications were seen in 8.9 %, including five patients who required early reoperation. Histology of RPLND specimen showed mature teratoma (41 %) and active cancer (11.5 %). Follow-up data were available for 66 patients (85 %). Median follow-up was 101 (11-207) months. Nine patients relapsed with median time to relapse 15 (8-60) months. Overall 5-year survival rate was 95.2 % (four deaths). CONCLUSION: In this relatively small series due to small population and low disease incidence, we have shown acceptable peri-operative course, morbidity and oncological outcomes with PC-RPLND compared to major international centres.

Early results of the use of collagenase in the treatment of Dupuytren's contracture.

INTRODUCTION: In recent years, the enzyme collagenase has been developed for the percutaneous treatment of Dupuytren's contracture, allowing management of the condition as an outpatient. We present early results on the treatment of Dupuytren's contracture using injectable collagenase. METHODS: Patients awaiting Fasciectomy for Dupuytren's Contracture were selected for enrolment. Contracture cords were then marked and injected with collagenase in the outpatients department. Twenty-four hours later, patients returned for an extension procedure, performed under regional anaesthesia. Hand therapy was then commenced as for surgical release. Contracture angles were measured pre-injection and at follow-up. RESULTS: Thirteen fingers were treated in 10 patients with a mean age of 66 years. Eight little fingers and five ring fingers were treated. Four fingers had isolated metacarpophalangeal joint (MCPJ) contracture, one finger had isolated proximal interphalangeal joint (PIPJ) contracture and the remainder had combined contractures. Mean pre-treatment MCPJ contracture was 58.6° and the mean pre-treatment PIPJ contracture was 39°. Post-treatment contracture was 4.23° and 9° for the MCPJ and PIPJ, respectively. All patients were satisfied with their results. COMPLICATIONS: Significant post-injection bruising occured in one patient. Skin tears occurred in 11 digits, and in all cases healed without intervention. No tendon rupture occurred. CONCLUSIONS: Collagenase is a safe and effective outpatient-based treatment for Dupuytren's contracture, which may be useful in controlling surgical waiting lists. We recommend its use as first-line treatment in patients who are unsuitable more invasive treatment alternatives.

Fracture of the scapular neck sustained in an arm wrestling match.

The sport of arm wrestling requires very little equipment, and can take place anywhere a flat surface is available. As such, undertrained participants often compete, with inevitable injury. Humeral fractures, and elbow injuries are well described, but scapular fractures have not previously been reported in the literature.
