    Quality of handwritten surgical operative notes from surgical trainees: a noteworthy issue
    Nzenza, TC ; Manning, T ; Ngweso, S ; Perera, M ; Sengupta, S ; Bolton, D ; Lawrentschuk, N (WILEY, 2019-03)
    BACKGROUND: Surgical operation notes are crucial for medical record keeping and information flow in continued patient care. In addition to inherent medical implications, the quality of operative notes also has important economic and medico-legal ramifications. Further, well-documented records can also be useful for audit purposes and propagation of research, facilitating the improvement of delivery of care to patients. We aimed to assess the quality of surgical operation notes written by junior doctors and trainees against a set standard, to ascertain whether these standards were met. METHOD: We undertook an audit of Urology and General Surgery operation notes handwritten by junior doctors and surgical trainees in a tertiary teaching hospital over a month period both in 2014 and 2015. Individual operative notes were assessed for quality based on parameters described by the Royal College of Surgeons of England guidelines. RESULTS: Based on the Royal College of Surgeons of England guidelines, a significant proportion of analysed surgical operative notes were incomplete, with information pertaining to the time of surgery, name of anaesthetist and deep vein thrombosis prophylaxis in particular being recorded less than 50% of the time (22.42, 36.36 and 43.03%, respectively).Overall, 80% compliance was achieved in 14/20 standards and 100% compliance was attained in only one standard. CONCLUSIONS: The quality of surgical operation notes written by junior doctors and trainees demonstrated significant deficiencies when compared against a set standard. There is a clear need to educate junior medical staff and to provide systems and ongoing education to improve quality. This would involve leadership from senior staff, ongoing audit and the development of systems that are part of the normal workflow to improve quality and compliance.

    Trends in the surgical treatment of benign prostatic hyperplasia in a tertiary hospital
    Ow, D ; Papa, N ; Perera, M ; Liodakis, P ; Sengupta, S ; Clarke, S ; Bolton, DM ; Lawrentschuk, N (WILEY, 2018-01)
    BACKGROUND: To assess current treatment trends and perioperative outcomes of transurethral resection of the prostate (TURP) and photoselective vaporization of the prostate (PVP) in a tertiary institution. METHODS: We prospectively collected a database of all patients undergoing TURP and PVP for benign prostatic hyperplasia (BPH) at a tertiary hospital between January 2011 and December 2013. Patient characteristics such as length of stay, readmission, anticoagulation status, American Society of Anesthesiologists (ASA) score and need for blood transfusion were recorded and analysed. RESULTS: In total, 560 cases were included: 204 (36.4%) underwent TURP and 356 (63.6%) PVP. Patients undergoing PVP had higher ASA scores (P < 0.001) and were more frequently on continuing anticoagulant therapy (P < 0.001). With regards to non-aspirin/asasantin coagulation therapy, 61 (17.1%) patients underwent PVP with their anticoagulants continued while no patients who received TURP continued anticoagulation. Blood transfusion percentages were similar at 1.0% for TURP and 1.7% for PVP but readmission proportions were higher after PVP (32 patients, 9.0%) compared to TURP (10 patients, 4.9%). These differences were attenuated when excluding patients continuing anticoagulation during the procedure. CONCLUSION: At our institution, the use of PVP has been increasing on a year-by-year basis. The results of the current study demonstrated that PVP is safe in patients with increased anaesthetic risk or on active anticoagulation when compared to traditional TURP. While this makes PVP an attractive alternative to TURP in high-risk anticoagulated patients, these patients may have complex post-discharge issues that should be addressed during the informed consent process.

    Declining use of radical prostatectomy and pelvic lymphadenectomy despite more robotics: National population data over 15 years
    Roberts, MJ ; Papa, N ; Perera, M ; Joshi, A ; Scott, S ; Bolton, D ; Lawrentschuk, N ; Yaxley, J (WILEY, 2020-04)
    AIM: To describe national surgical patterns of prostate cancer (PCa) care considering radical prostatectomy with or without pelvic lymphadenectomy and consideration of robotic-assisted techniques. METHODS: Retrospective analysis of publicly accessible Medicare claims data was performed for the period 2001-2016 and included patients undergoing radical prostatectomy with or without pelvic lymphadenectomy relative to total and PCa-specific populations among men aged 45-84 years. Proportion of cases performed robotically was considered. RESULTS: Total procedures performed increased from 2001, peaked in 2009 and subsequently decreased until 2016. Since 2009, the age-specific rate of surgery in men aged 75-84 increased by 2.3-fold, whereas the rates for men aged 55-64 and 45-54 reduced by 44% and 55%, respectively. Rates of concurrent pelvic lymphadenectomy fell until 2009 with subsequent stabilization (ratio 1.05-1.14) through to 2016. Significant regional practice patterns were observed, as was an increasing trend toward a robotic-assisted laparoscopic approach, comprising more than 80% of radical prostatectomies in 2016. CONCLUSION: Since the peak in 2009, radical prostatectomy is performed less in men <65 years and more in men ≥65 years. An increasing proportion of cases omit concurrent pelvic lymphadenectomy and are performed robotically.

    Mesenteric metastases from mature teratoma of the testis: A case report
    Loh, Z ; Manning, TG ; O'Brien, JS ; Perera, M ; Lawrentschuk, N (ELSEVIER SINGAPORE PTE LTD, 2020-07)
    Metastatic spread of testicular cancer has been well documented, with 95% of cases involving para-aortic retroperitoneal lymph nodes. Mesenteric lymphatic basins do not lie within the canonical drainage pathway of the testes and represent a rare site of metastasis. Various mechanisms of spread to the mesentery have been described, including direct extension and haematogenous dissemination. We present a case of a previously-well 43-year-old man who presented with right scrotal discomfort and intermittent lower back pain, who was found to have mesenteric metastases from a non-seminomatous germ cell tumour of the testis. Managing lymphadenopathy that lies outside of standard resection templates remains a complex surgical challenge. Here we present the first case in the English medical literature with co-existing supradiaphragmatic axillary and mediastinal nodal disease.

    Qu, LG ; Perera, M ; Lawrentschuk, N ; Umbas, R ; Klotz, L (SPRINGER, 2021-09)
    PURPOSE: Contemporary, original research should be utilised to inform guidelines in urology relating to the COVID-19 pandemic. This comprehensive review aimed to: identify all up-to-date original publications relating to urology and COVID-19, characterise where publications were from, and outline what topics were investigated. METHODS: This review utilised a search strategy that assessed five electronic databases, additional grey literature, and global trial registries. All current published, in-press, and pre-print manuscripts were included. Eligible studies were required to be original research articles of any study design, reporting on COVID-19 or urology, in any of study population, intervention, comparison, or outcomes. Included studies were reported in a narrative synthesis format. Data were summarised according to primary reported outcome topic. A world heatmap was generated to represent where included studies originated from. RESULTS: Of the 6617 search results, 48 studies met final inclusion criteria, including 8 pre-prints and 7 ongoing studies from online registries. These studies originated from ten countries according to first author affiliation. Most studies originated from China (n = 13), followed by Italy (n = 12) and USA (n = 11). Topics of the study included pathophysiological, administrative, and clinical fields: translational (n = 14), COVID-19-related outcomes (n = 5), urology training (n = 4), telemedicine (n = 7), equipment and safety (n = 2), urology in general (n = 4), uro-oncology (n = 3), urolithiasis (n = 1), and kidney transplantation (n = 8). CONCLUSION: This review has outlined available original research relevant to COVID-19 and urology from the international community. This summary may serve as a guide for future research priorities in this area.

    Optimising patient outcomes with photoselective vaporization of the prostate (PVP): a review
    Pascoe, C ; Ow, D ; Perera, M ; Woo, HH ; Jack, G ; Lawrentschuk, N (AME PUBLISHING COMPANY, 2017-07)
    Benign prostatic hyperplasia (BPH) is a common pathology causing lower urinary tract symptoms (LUTS) and may significantly impact quality of life. While transurethral resection of the prostate (TURP) remains the gold standard treatment, there are many evolving technologies that are gaining popularity. Photoselective vaporization of the prostate (PVP) is one such therapy which has been shown to be non-inferior to TURP. We aimed to review the literature and discuss factors to optimise patient outcomes in the setting of PVP for BPH. A comprehensive search of the electronic databases, including MEDLINE, Embase, Web of Science and The Cochrane Library was performed on articles published after the year 2000. After exclusion, a total of 38 papers were included for review. The evolution of higher powered device has enabled men with larger prostates and those on oral anticoagulation to undergo safely and successfully PVP. Despite continued oral anticoagulation in patients undergoing PVP, the risk of bleeding may be minimised with 5-Alpha Reductase Inhibitor (5-ARI) therapy however further studies are required. Pre-treatment with 5-ARI's does not hinder the procedure however more studies are required to demonstrate a reliable benefit. Current data suggests that success and complication rate is largely influenced by the experience of the operator. Post-operative erectile dysfunction is reported in patients with previously normal function following PVP, however those with a degree of erectile dysfunction pre-operatively may see improvement with alleviation of LUTS.

    Incidental prostate cancer in transurethral resection of prostate specimens in men aged up to 65 years
    Perera, M ; Lawrentschuk, N ; Perera, N ; Bolton, D ; Clouston, D (ELSEVIER INC, 2016-03)
    BACKGROUND: The identification of prostate cancer (PC) is important in men aged ≤ 65 years. We examined complete transurethral resection of prostate (TURP) specimens to quantify the incidence and nature of PC in men aged ≤ 65 years. METHODS: A prospective multi-institutional database included TURP specimens. The cohort was stratified into two groups according to age. For men aged ≤ 65 years, the entire specimen was submitted for histological analysis, while the TURP specimens from men aged > 65 years were sampled following standard guidelines. RESULTS: A total of 923 men were included, with 224 in the younger group. PC was identified in 13.4% in men aged ≤ 65 years, compared with 28.7% the older group. The younger group had a lower proportion of Gleason score ≥ 7 (30% compared with 40%) and higher rates of pT1a (57% compared with 43%). In men aged ≤ 65 years with cancer, tumor was identified in one block in 15 of 30 cases (50%). Following diagnosis, 4/30 underwent radical prostatectomy, 5/30 underwent curative radiotherapy, 10/30 androgen deprivation, and 1/30 received palliative radiotherapy. CONCLUSION: Incidental PC in men aged ≤ 65 years is not uncommon. Our results suggest that TURP specimens in men aged ≤ 65 years should be completely assessed. Underidentification of cancer may occur as a result of increasing use of laser prostatectomy and the consequent loss of tissue for pathological examination.

    Prostate cancer screening with prostate-specific antigen: A guide to the guidelines
    Cabarkapa, S ; Perera, M ; McGrath, S ; Lawrentschuk, N (ELSEVIER INC, 2016-12)
    BACKGROUND: Prostate cancer remains the most common non-skin cancer malignancy in men. Prostate-specific antigen (PSA) is recognized as a biomarker for the diagnosis, monitoring, and risk prediction of prostate cancer. Its use in the setting of prostate cancer screening has been controversial due to the risk of over diagnosis and over treatment. OBJECTIVE: Within Australia, there are inconsistent recommendations surrounding the use of PSA screening in clinical practice. In light of the 2016 PSA-screening guidelines by the major Australian health authorities, the current review aims to highlight the controversies and objectively outline the current recommendations within Australia. DISCUSSION: Health-care authorities across Australia have issued conflicting guidelines for prostate cancer screening culminating in confusion amongst health care practitioners and members of the public alike. A general consensus is held by other countries across the globe but differences amongst the specific details in how to best employ a PSA screening program still exist.

    Prostate cancer biomarkers: Are we hitting the mark?
    McGrath, S ; Christidis, D ; Perera, M ; Hong, SK ; Manning, T ; Vela, I ; Lawrentschuk, N (ELSEVIER INC, 2016-12)
    PURPOSE: Localised prostate cancer diagnosis and management is increasingly complex due to its heterogeneous progression and prognostic subgroups. Pitfalls in current screening and diagnosis have prompted the search for accurate and invasive molecular and genetic biomarkers for prostate cancer. Such tools may be able to distinguish clinically significant cancers from less aggressive variants to assist with prostate cancer risk stratification and guide decisions and healthcare algorithms. We aimed to provide a comprehensive review of the current prostate cancer biomarkers available and in development. METHODS: MEDLINE and EMBASE databases searches were conducted to identify articles pertaining to the use of novel biomarkers for prostate cancer. RESULTS: A growing number of novel biomarkers are currently under investigation. Such markers include urinary biomarkers, serology-based markers or pathological tissue assessments of molecular and genetic markers. While limited clinical data is present for analysis, early results appear promising. Specifically, a combination of serum and urinary biomarkers (Serum PSA + Urinary PCA3 + Urinary TMPRSS2-ERG fusion) appears to provide superior sensitivity and specificity profiles compared to traditional diagnostic approaches (AUC 0.88). CONCLUSION: The accurate diagnosis and risk stratification of prostate cancer is critical to ensure appropriate intervention. The development of non-invasive biomarkers can add to the information provided by current screening practices and allows for individualised risk stratification of patients. The use of these biomarkers appears to increase the sensitivity and specificity of diagnosis of prostate cancer. Further studies are necessary to define the appropriate use and time points of each biomarker and their effect on the management algorithm of prostate cancer.
