Predictive Value of Transrectal Ultrasonic Doppler and Elastographic Features in Prostate Cancer Detection in Lagos University Teaching Hospital.

Introduction: This study aimed at determining the predictive value (PV) of transrectal ultrasonic Doppler and elastographic features in prostate cancer (PCa) detection among patients in Lagos University Teaching Hospital. Materials and Methods: This prospective study involved patients that underwent evaluation for PCa. Participants had digital rectal examination (DRE), prostate-specific antigen (PSA) assay, and transrectal ultrasound-guided prostate biopsy using colour Doppler (CD) and elastography. All cores were sent for histopathology. Data were analysed using Statistical Package for the Social Sciences Version 22.0. CD and elastography PV in PCa detection and their relationships to the Gleason score (GS) were analysed (P < 0.05). Results: Seventy men (aged between 45 and 87 years) were enrolled. Forty-three (61.4%) patients had PCa with a mean age of 69.37 ± 8.22years. The sensitivity, specificity, positive PV (PPV), negative PV (NPV) and accuracy of CD were 8.50%, 97.44%, 64.10%, 66.42% and 66.31%, respectively. The sensitivity, specificity, PPV, NPV and accuracy of elastography were 84.21%, 94.59%, 88.89%, 92.11% and 91.07%, respectively. Conclusion: There is a significant association between decreased elasticity (elastography) and PCa detection but a weak association between increased vascularity (CD) and PCa detection. A positive correlation exists between extent of prostatic stiffness and GS.

Gamified antimicrobial decision support app (GADSA) changes antibiotics prescription behaviour in surgeons in Nigeria: a hospital-based pilot study.

AIMS: Surgical Antibiotic Prophylaxis (SAP) in Nigeria is often not evidence based. The aim of this study is to test if the GADSA application can change prescription behaviour of surgeons in Nigeria. In addition, the study aims to identify AMS strategies and policies for the future. METHODS: The GADSA gamified decision support app uses WHO and Sanford prescribing guidelines to deliver real-time persuasive technology feedback to surgeons through an interactive mentor. The app can advise on whether clinician's decisions align with SAP recommendations and provides the opportunity for clinicians to make adjustments. Twenty surgeons actively participated in a 6-month pilot study in three hospitals in Nigeria. The surgeons determined the risk of infection of a surgical procedure, and the need, type and duration of SAP. The study used a longitudinal approach to test whether the GADSA app significantly changed prescribing behaviour of participating surgeons by analysing the reported prescription decisions within the app. RESULTS: 321 SAP prescriptions were recorded. Concerning the surgical risk decision, 12% of surgeons changed their decision to be in line with guidelines after app feedback (p < 0.001) and 10% of surgeons changed their decision about the need for SAP (p = 0.0035) to align with guidelines. The change in decision making for SAP use in terms of "type" and "duration" to align with guidelines was similar with 6% and 5% respectively (both p-values < 0.001). CONCLUSION: This study suggests that the GADSA app, with its game based and feedback feature, could significantly change prescribing behaviour at the point of care in an African setting, which could help tackle the global challenge of antibiotic resistance.

Urethral length and its relationship with anthropometric parameters in adult male Nigerians.

BACKGROUND: The available literature on urethral length in adult males is limited. To the best of our knowledge, such measurement has never been carried out amongst Nigerian and African men. This study aimed to document average urethral length as well as the relationship between urethral length and age, and anthropometric parameters amongst the Nigerian male adult population to add to the database for urethral length. METHODS: It was a prospective cross-sectional study amongst adult male Nigerians who had an indication for urethral catheterization as part of their regular treatment at the urologic clinics as well as male adult patients who required urethral catheterization in the theatre and the wards for various reasons. All patients had anthropometric parameters measured or calculated. The total usable length (A) of the catheter was measured before catheterization and the unused catheter length (B) was measured after catheterization for each patient. The calculated urethral length (C) was obtained by subtracting B from A. Data were analyzed using SPSS version 26.0. Mean urethral length was determined while the correlation between urethral length and age as well as anthropometric parameters were determined using Pearson Correlation. RESULTS: A total of 450 adult males were recruited. The mean age of subjects was 63.58 years with a range of 22-91 years. The average total usable and unused catheter lengths were 30.01 and 8.97 cm respectively. The mean urethral length among participants was 21.32 cm (8.4 Inches) with a range of 16.5 to 28 cm (6.5-11.0 Inches). There were no statistically significant correlations between urethral length and age ([r (450) = - 0.029, p = 0.546]) as well as with anthropometric parameters (height: r (450) = - 0.088, p = 0.61; weight: [r (450) = - 0.047, p = 0.324 and BMI: r (450) = - 0.082, p = 0.08) in adult males. CONCLUSION: This study suggests that there may be racial differences in adult male urethral length but no relationship with age and anthropometric parameters. Further research is needed to explore these findings.

A comparison of loupe-assisted and non-loupe-assisted subinguinal varicocelectomy.

Introduction: Varicocele is a treatable aetiology of male infertility. Magnification with surgical loupe has been associated with improved outcome and reduced morbidity than the conventional technique without magnification. Objective: To compare the outcomes of two techniques of subinguinal varicocelectomy, with a surgical loupe and without. Patients and Methods: This was a prospective randomised hospital-based study. Forty-six patients were randomised to two arms - Group A: loupe-assisted subinguinal varicocelectomy (LASV) and Group B: open subinguinal varicocelectomy without Loupe (OSV). They all had their semen and hormonal parameters compared preoperatively and at 3 and 6 months postoperatively. Post-operative complications were also assessed. P < 0.05 was considered statistically significant. Results: The mean age was 38.28 ± 4.55 years with a range of 27-46 years. The mean age in Group A was 37.35 ± 4.68 and 39.22 ± 4.33 years in Group B. There was an improvement in motility, sperm count and concentration in both the groups at 3 and 6 months (P < 0.05). However, there was no difference in these parameters on comparison of the two groups at 3 and 6 months (P > 0.05). Follicle-stimulating hormone decline was significant in the OSV group at 3 and 6 months, P = 0.010 and 0.021, respectively. There was no difference in other hormonal parameters both at 3 and 6 months (P > 0.05). The pregnancy rate in each arm of study was 4.3%. All complications occurred in Group B. Conclusion: Both techniques resulted in improvement in seminal fluid parameters. All complications occurred in the arm that had subinguinal varicocelectomy without loupe. Loupe-assisted subinguinal varicocelectomy is safe and effective.

Quality and appropriateness of uro-surgical referrals at a Nigerian teaching hospital.

Introduction: An effective referral system is crucial for a high-quality health system that provides safe medical care. Aim and Objectives: This study aimed at evaluating the appropriateness and adequacies of information in the referral letters of patients. Materials and Methods: A prospective study of referral letters of all new patients in the urology clinic. Information retrieved was socio-demographic characteristics, source of referral and presence or absence of important information in their letters. We compared the information provided to the new history taken to determine the appropriateness and adequacy using different domains of medical history. Referrals were adjudged appropriate if the diagnosis is urologic, while any referral lacking relevant information is adjudged inadequate. The results were displayed using the simple proportions in tables and charts. Results: A total of 1188 referrals were reviewed. There were 997 (83.9%) males and 191 (16.1%) females. Referrals from private hospitals were the most common in 627 (52.8%) cases. Of all new referrals, 1165 (98.1%) were adjudged to be appropriate, while 23 (1.9%) were inappropriately referred. Referrals from teaching hospitals had higher proportions of good-quality referrals than those from primary healthcare and private centres. The most common deficiencies were the lack of documentation of relevant examination findings (37.8%) and provisional diagnosis (21.4%). The majority, 956 (80.5%), of letters were narrative in nature, whereas 232 (19.5%) were structured. Structured letters were found to be more informative. Conclusion: A significant percentage of referral letters lacked completeness in many key areas. We recommend the use of structured forms or template letters to improve the quality of referrals.

Urological Surgeries in a West African Teaching Hospital.

Introduction: Urological surgeries are a significant part of surgical services. The need for these services varies regionally and globally. Knowledge of the local need is important for prioritisation of resources. Objectives: To describe the urological procedures done in our hospital for effective utilisation of the already scarce resource in this region. Patients and Methods: This was a retrospective one-year study of the urosurgical cases done in a Nigerian Teaching Hospital. The main theatre register was used to collate data. Data collected included age, sex, operation done and anaesthesia employed. Results: One hundred and twenty-two male and three female patients were included with a male-to-female ratio of 41:1. The mean age of the patients was 56.6 ± 19.89 years. Elective cases accounted for 102 (81.6%) of surgeries. Regional anaesthesia was the most common form of anaesthesia accounting for 105 (84%) followed by local anaesthesia in 16 (12.8%). Day cases accounted for 77 (61.6%) of procedures. More than 80% of the study population was 50 years and older. Overall, the three most common performed surgeries were digital-guided prostate biopsy 47 (37.6%), suprapubic cystostomy 16 (12.8%) and open prostatectomy 9 (7.2%). In male patients, the three most common procedures were prostate biopsy 47 (38.5%), suprapubic cystostomy 16 (13.1 %), open prostatectomy 9 (7.4%) whereas nephrectomy, pyeloplasty and stent removal each accounted for 33.3% each of procedures in female patients. Endourological procedures accounted for 5 (4%) of cases. Conclusion: Open surgeries accounted for the majority of these cases done with prostate-related procedures being the most common procedures. Few endourological procedures were performed.

The Burden of Urologic Diseases in a Tertiary Hospital in South-eastern Nigeria: A Three-Year Review.

Background: Urological diseases are an integral part of the surgical burden of diseases. There are national, regional, and global variations. Characterisation of the burden of disease in this specialty is important for the registry and in allocation of the already scarce resource in this sub-region. Objective: This study was aimed at characterising the burden of urological diseases in our teaching hospital as a means towards addressing the gap between resources and urological needs. Materials and Methods: It was a retrospective study of new patients seen over 3 years from January 2019 to December 2021 at the urology clinics of Alex-Ekwueme Federal University Teaching Hospital Abakaliki. Data collected included sex, age, and diagnosis. Data analysis was done using SPSS version 26. Results: A total of 2893 patients were available for analysis, of which 2777 (96%) were male patients whereas 116 (4%) were female patients with a male-to-female ratio of 23.9:1. The mean age of the patients was 58.11 ± 16.76 years. The common presentations were benign prostatic enlargement (BPE) 1515 (52.4%), cancer of the prostate (CAP) 349 (12.1%), urethral stricture disease 268 (9.3%), and urinary tract infection (UTI) 192 (6.6%). In men, the three most common diagnoses were prostate-related diseases 1864 (67.1%), urethral stricture disease 268 (9.70%), and UTI 170 (6.1%), whereas, in women, urolithiasis, urinary tract infection, and hydronephrosis accounted for 50 (43.1%), 22 (19%), and 20 (17.2%), respectively. Conclusion: BPE, CAP, and urethral stricture disease were the most common presentations in men whereas urolithiasis, UTI, and hydronephrosis were common in women. This knowledge can be used to channel hospital resources appropriately.

Leydig Cell Testicular Tumor Presenting as Bilateral Breast Masses: A Case Report.

Leydig cell tumors are rare but are the most common nongerm cell gonadal tumors. They are mostly benign but malignant variants have been reported. Leydig cells constitute the main androgen-synthesizing compartment in adult males but are also capable of estrogen production. This can manifest with clinical features of excessive hormone elaboration. We report a case of a 39-year-old man with abnormal bilateral breast development, reduced libido, and weak erection of 3 years' duration. He never noticed any testicular swelling before presentation. Examination revealed well-developed breasts bilaterally and a mass in the lower pole of the left testis. Scrotal ultrasound confirmed a hypoechoic tumor measuring 2 × 3 cm in the lower pole of the left testis and hormonal evaluation revealed a markedly elevated estradiol level. A diagnosis of estrogen-secreting testicular tumor was made. He had a testis-sparing excision of the scrotal lesion as well as liposuction and excision of glandular tissues of the breasts. He had an uneventful postoperative recovery and was discharged a day after surgery. Histology of excised testicular lesion revealed a benign Leydig cell tumor. Four months following surgery, there was an improvement in libido, erection, and sperm concentration of the patient. The patient was also very satisfied with the cosmetic outcome of the excision of the bilateral gynecomastia. We recommend self-examination of testicles as an important step for early diagnosis of testicular tumors.

Prostate Cancer and Challenges in Management in a Semi-urban Centre: A 10-year Experience.

Introduction: Prostate cancer (CaP) is the second most common cancer in men and the fifth most common cancer worldwide. The incidence in Nigeria is rising. Numerous challenges exist that prevent the successful management of these patients in this subregion. Aims and Objectives: This study aimed to report on the modes of presentation and difficulties encountered in managing patients with CaP in our environment with a view to finding solutions to these challenges. Materials and Methods: This was a retrospective study of all CaP patients who were managed in Alex-Ekwueme Federal University Teaching Hospital, Abakaliki, Ebonyi State, Nigeria over a 10-year period from 2012 to 2021. Data were collated using a pro forma. Numerical data were summarized as means, median, and standard deviation, whereas categorical data were summarized as frequencies. Statistical significance was pegged at P < 0.05. Results: Seventy-three patients were analysed. The mean age of the patients was 71.48 ± 8.15 years. The three most common presenting complaints were lower urinary tract symptoms (LUTSs) 23 (31.5%), acute urinary retention 9 (12.3%), and LUTS with low back pain 9 (12.3%). The median duration of symptoms was 6.5 months. No difference was noted among educational level, occupation, and stage of CaP, (P=0.222 and P=0.548), respectively. The median total prostate-specific antigen was 85.0 ng/mL. Sixty-seven patients (91.8%) had an abdominopelvic ultrasound scan. Fifty patients (68.5%) had stage 4 disease. Thirty-eight (52.1%) had financial constraints. Forty-nine (67.1%) patients were lost to follow-up. Bilateral orchidectomy was offered to 28 (38.4%) patients. Conclusion: Financial constraint was a huge barrier in the management of CaP patients in this study. Late presentation was common in this study.

Exploring barriers to guideline implementation for prescription of surgical antibiotic prophylaxis in Nigeria.

Background: In Nigeria, the prescription of surgical antibiotic prophylaxis for prevention of surgical site infection tends to be driven by local policy rather than by published guidelines (e.g. WHO and Sanford). Objectives: To triangulate three datasets and understand key barriers to implementation using a behavioural science framework. Methods: Surgeons (N = 94) from three teaching hospitals in Nigeria participated in an online survey and in focus group discussions about barriers to implementation. The theoretical domains framework (TDF) was used to structure question items and interview schedules. A subgroup (N = 20) piloted a gamified decision support app over the course of 6 months and reported barriers at the point of care. Results: Knowledge of guidelines and intention to implement them in practice was high. Key barriers to implementation were related to environmental context and resources and concern over potential consequences of implementing recommendations within the Nigerian context applicable for similar settings in low-to-middle-income countries. Conclusions: The environmental context and limited resource setting of Nigerian hospitals currently presents a significant barrier to implementation of WHO and Sanford guidelines. Research and data collected from the local context must directly inform the writing of future international guidelines to increase rates of implementation.

Analysis of 87 Nephrectomies in a Tertiary Healthcare Center in Nigeria.

Background: Nephrectomy is one of the most frequently performed operations on the kidney. It is necessary for treatment of malignant as well as some benign renal conditions. Methodology: This was a five-year retrospective review of all adult patients who had open nephrectomy in Lagos University Teaching Hospital, Lagos, Nigeria between January 2014, and December 2019. The cases were traced using clinic, ward, and theatre records. The clinical and operative details of these patients were retrieved and analysed. Clinical information extracted included patients' demography, clinical presentations, diagnosis, procedures performed, complications and the immediate treatment outcome. Data were analysed using SPSS for Mac Version 25.0. Results were displayed in simple proportions using tables and charts. Results: A total of 87 patients' records were available for review. Age range was15-76years with a mean and median age of 49.415 and 52 years, respectively. Majority, 73(83.9%) of the patients presented with at least one symptom, whereas14(17.7%) were asymptomatic. Loin pain was the commonest presentation in 72(82.8%). Indication for nephrectomy were benign in 28(32.2%) and malignant in 59(67.8%) patients. Overall, renal cell carcinoma was the most common indication for nephrectomy accounting for 59.8% of all nephrectomies. A total of thirty-one morbidities occurred in sixteen patients with a complication rate of 18.4% while transfusion rate was 40.2%. Reoperation and mortality rates were 2.3 and 3.4%, respectively. Conclusion: Malignant renal tumors are predominant indications for nephrectomy in our institution. Though associated with a high transfusion rate, open nephrectomy remains a safe procedure with a good short-term outcome.

Monopolar transurethral resection of the prostate using water as the irrigation fluid: Our initial experience.

BACKGROUND: Monopolar transurethral resection of the prostate (M-TURP) has been the gold standard of surgical intervention in patients with benign prostatic hyperplasia with the indication for surgery. This can be achieved using varieties of irrigation fluids. OBJECTIVES: To document our experience with M-TURP using water as irrigation fluid in 123 consecutive patients. MATERIALS AND METHODS: A retrospective study of all patients who had M-TURP with water as irrigation fluid was performed between January 2017 and July 2019. Information retrieved from theatre records and case notes includes patient's socio-demographic data, indications for surgery, intra-operative findings, the volume of resected chips and irrigation fluid used, post-operative complications and patient's satisfaction with the outcome of the procedure. These data were analysed using SPSS version 23. RESULTS: Data from 123 patients were analysed and presented. The age range was 44-96 years with a mean of 69 years. Prostate volume ranges from 13.9 to 276.00 mls with a mean of 95.69 mls while resected prostate volume ranges from 2.0 to 158.0 mls with a mean of 56.68 mls. Volume of the sterile water used as irrigation fluid ranged from 5.0 L to 174.0 L with a mean of 68.7 L. Mean reduction in International Prostate Symptoms Score, improvement in Q-max and reduction in post-void residual urine were 22.1, 16.9 and 141.6 mls, respectively. Transfusion rate was 6.5% while the duration of admission ranges from 1 to 6 days, with a mean of 2.5 days. The overall complication rate was 26.0%. Ninety-six percent were satisfied with the outcome. CONCLUSION: M-TURP using water as irrigation fluid is safe and is as good as using the more rather expensive glycine or normal saline in bipolar TURP.

Assessment of Health-care Research and Its Challenges among Medical Doctors in Nigeria.

INTRODUCTION: Health-care research in Nigeria has been growing over the years but is constrained by many difficulties. This study aimed to identify the challenges encountered in health-care research and suggest policies to address these problems. MATERIALS AND METHODS: It was a cross-sectional study of medical doctors who have been involved in health-related researches. All participants filled a self-administered online questionnaire comprising 31 questions in five sections. The responses were analyzed using the Google forms and the Statistical Package for the Social Sciences software version 23. RESULTS: The mean age of the study participants was 41.0 ± 8.4 years. Three-quarters of the respondents (75.5%) worked in teaching hospitals. Nearly all (96.6%) carried out their studies using personal funds and only one in 10 had been involved in high-budget projects (≥₦1,000,000). The generation of quality researches was impeded by the restriction of literature review to free online journals (93.2%), incomplete health records (88.0%), limited access to research kits (65.7%), limited use of advanced statistical analysis (29.8%), and challenges with obtaining ethical approval (21.2%). Despite the average online visibility of these researches (52.2%), only 28.5% stated that it has been locally adopted to influence medical practice in their center. CONCLUSION: There is a wide disparity in research capacity among hospital tiers. It is important to leverage on and expand existing partnerships to provide institutional access to premium literature, offer robust, and assessable financial support for the conduct of high-quality researches and provide a framework to bridge the gap in the use of these works to influence practice change in Nigeria.

Delay of Surgery Start Time: Experience in a Nigerian Teaching Hospital.

BACKGROUND: Operating room delay has multiple negative effects on the patients, surgical team, and the hospital system. Maximum utilization of the operating room requires on-time knife on the skin and efficient turnover. Knowledge of the reasons for the delay will form a basis toward proffering solutions. PATIENTS AND METHODS: This was a prospective study of all consecutive elective cases done over a 15-month period from January 2016 to March 2017. Using our departmental protocol that "knife on skin" for the first elective case should be 8.00am, the delay was defined as a surgery starting later than 8.00am for the first cases while the interval between the cases of >30 min for the knife on the skin was used for subsequent cases. Reasons for delay in all cases of delay were documented. The prevalence and causes of the delays were analyzed. P < 0.05 was considered statistically significant. RESULTS: Of 1178 surgeries performed during the period of study, 1170 (99.3%) of cases were delayed. The mean delay time was 151 min for all cases. First on the list had a longer delay time than others; 198.9 min versus 108.5 min (P = 0.000). Delay in the first cases accounted for 47.5% of all delayed cases. Overall, patient-related factor was the most common cause of delay (31.3%) followed in descending order by surgeon-related factor (28.5%) and hospital-related factor (26.2%). Patient-related factors accounted for 43.2% of first-case delays. CONCLUSION: Delays encountered in this study were multifactorial and are preventable. Efforts should be directed at these different causes of delay in the theater to mitigate these delays and improve productivity.

Survey of prostate biopsy practices among urologists in Nigeria.

BACKGROUND: Prostate biopsy (PB) is one of the most commonly performed procedures by urologists in our practice. It is the confirmatory diagnosis of the most common malignancy in elderly men. Currently, there is no national guideline on PB in Nigeria; hence, practices vary among urologists and institutions. The sudy aim was to highlight the various PB practices among Nigerian urologists with a view to determining the gap between our practice and evidenced-based global practice. MATERIALS AND METHODS: A descriptive cross-sectional study which utilised self-administered questionnaires distributed among urologists who participated at the Nigerian Association of Urological Surgeons' (NAUS) Conference in Lagos in 2014. RESULTS: The total number of respondents was 102, distributed across 26 states and various levels of the hospital. All respondents stated that they always perform biopsy if prostate-specific antigen (PSA) was >10 ng/ml. Seventy-nine (77.5%) respondents routinely rely on PSA kinetics in taking a decision on PB. About four-fifth routinely discontinue aspirin before the biopsy. All respondents administer antibiotics with a preference for the parenteral route in 74.5%. Anaesthesia employed for PB included, regional by 52 respondents (50.9%), local by 39 respondents (38.2%), and general by 1 respondent (1.0%), respectively. Transrectal route was preferred by 96 (94.1%). Majority (74.6%) still practice digitally-guided biopsy, whereas 25.4% perform the transrectal ultrasound-guided biopsy. The number of cores commonly taken for systematic technique ranges from 6 to 18. About a quarter (25.5%) had personal or institutional publication (s) on PB. CONCLUSION: PB practice vary among Nigerian urologists. The variability depends on individual training, preference and available institutional facilities. We recommend that NAUS should provide a guideline for the practices of PB in Nigeria.

Management of a giant prostatic enlargement: Case report and review of the literature.

Giant prostatic enlargement often referred to as giant prostatic hyperplasia (GPH) is a rare condition described as a massive prostatic enlargement >500 g. Up until now, the total number of GPH reported worldwide in medical literature is < 30. To the best of our knowledge, only one case of a giant prostate has been reported in Nigeria. We report a case of a giant prostatic enlargement treated by open simple retropubic prostatectomy in a 73-year-old man who was suffering from lower urinary tract symptoms and persistent visible (gross) haematuria necessitating repeated blood transfusions. Transrectal ultrasound (TRUS) scan revealed a markedly enlarged prostate measuring 565 ml with a suspicious nodule and prostate-specific antigen level of 48.5 ng/ml. He had a 20-core TRUS-guided prostatic biopsy which showed benign prostatic hyperplasia. We performed a retropubic open simple prostatectomy for complete enucleation of the adenoma. Specimen weighed 512.5 g with dimensions of 17 cm × 16 cm and a volume of 528 ml. Histological examination showed prostatic fibromuscular hyperplasia with a focus of adenocarcinoma. The patient had an uneventful post-operative recovery and was discharged within a week post-surgery. Urethral catheter was removed after 2 weeks with satisfactory outcome.

An Assessment of the Correlation between Tests of Clinical Competence and Tests of Cognitive Knowledge amongst Nigerian Resident Doctors in Surgery.

Background: Assessment of clinical competence involves the assessment of cognition and assessment of clinical performance (behaviour in practice). The limitations of the traditional long case examination (LCE) in the assessment of clinical performance led to its replacement with the objective structured clinical examination (OSCE) by many institutions. Aims: To determine and compare the abilities of the OSCE and LCE to predict candidates' performance in the tests of cognitive knowledge in the fellowship examination of the National Postgraduate Medical College of Nigeria in the Faculty of Surgery. Materials and Methods: The results of the OSCE, LCE, written papers, picture tests (PTs), vivas, and the total clinical score (TCS) of surgical residents who took part in the fellowship examination over six consecutive examination periods were compared by using the Pearson's correlation coefficient. A P-value less than.01 was considered as significant. Results: The OSCE had a weak but statistically significant positive correlation (.175) with the LCE. Both the OSCE and LCE had similar correlations with the total written papers (TWP) and PTs. The viva had a higher correlation with the OSCE than the LCE. The TCS when compared with either the OSCE or LCE alone had a higher correlation with most of the tests of cognitive knowledge. Conclusion: Neither the OSCE nor the LCE showed any superiority over the other in terms of the ability to predict performance in the tests of cognition. The TCS appears superior to either the OSCE or the LCE as a predictor of the candidates' overall knowledge of surgery. Therefore, both the OSCE and the LCE should be retained as part of the examination.

Contexte: L'évaluation de la compétence clinique implique l'évaluation de la cognition et l'évaluation de la performance clinique (comportement dans la pratique). Les limites de l'examen de cas long traditionnel (LCE) dans l'évaluation de la performance clinique ont conduit à son remplacement par l'examen clinique objectif structuré (ECOS) par de nombreuses institutions. Objectifs: Déterminer et comparer les capacités de l'ECOS et du LCE à prédire les performances des candidats aux tests de connaissances cognitives lors de l'examen de bourse de la faculté de chirurgie du Nigerian National Postgraduate Medical College. Méthodes: Les résultats de l'ECOS, du LCE, des documents écrits, des tests d'image, des vivas et du score clinique total (TCS) des résidents en chirurgie qui ont participé à l'examen de bourse sur six périodes d'examen consécutives ont été comparés en utilisant le coefficient de corrélation de Pearson. Une valeur de p inférieure à 0,01 était considérée comme significative. Résultats: L'ECOS avait une corrélation positive faible mais statistiquement significative (0,175) avec le LCE. L'ECOS et le LCE avaient des corrélations similaires avec le nombre total d'épreuves écrites (TWP) et les tests d'images. La soutenance avait une corrélation plus élevée avec l'ECOS que le LCE. Le score clinique total (TCS), comparé à l'ECOS ou au LCE seul, présentait une corrélation plus élevée avec la plupart des tests de connaissances cognitives. Conclusion: Ni l'OSCE ni le LCE n'ont montré de supériorité sur l'autre en termes de capacité à prédire la performance dans les tests de cognition. Le TCS semble supérieur à l'ECOS ou au LCE en tant que prédicteur des connaissances globales des candidats en chirurgie. Par conséquent, l'ECOS et le LCE devraient être retenus dans le cadre de l'examen.

Endoscopic Management of Ureteric Stones: Our Initial Experience.

AIMS: The aim of this study is to present our initial experience with intracorporeal pneumatic ureterolithotripsy highlighting the pattern of patients' clinical presentation, techniques, and limitation of the procedure. MATERIALS AND METHODS: This is a retrospective study of cases of ureteric stones managed over a period of 18 months in a private hospital. Data obtained include patients' sociodemography, clinical presentation, stone burden, procedural technique, complication, and need for a secondary procedure. Data were analyzed using the Statistical Package for the Social Sciences version 21. RESULTS: The total number of patients managed was 20 with an age range of 28-75 years and a mean of 48.2 ± 12.4 years. Majority of them, i.e., 11 (55%) were middle aged. Female gender was more predominant, 11 (55%). Flank pain was the most common mode of presentation. Right-sided stone occurred in 9 (45%), left sided in 7 (35%), and bilateral in 4 (20%). Stone location was in the upper ureter in 4 (16.7%), mid-ureter in 7 (29.2%), and lower ureter in 13 (54.2%). The stone size ranged from 6 to 18 mm with a mean of 9.7 ± 2.5 mm. Four patients (20%) required initial bilateral ureteric stenting before definitive procedure to allow for recovery from sepsis and/or nephropathy. All patients had double-J stenting and were discharged 2 days after the procedure. The procedure was successful in 19 (95%) with 100% stone clearance rate and complete resolution of symptom without any complication. One patient (5%) had a very hard upper ureteric stone which retropulsed into the renal pelvis requiring open nephrolithotomy. CONCLUSION: Endoscopic treatment of ureteric stone with intracorporeal pneumatic lithotripsy is a safe and effective treatment modality. It is, however, limited in the management of hard upper ureteric stone, especially those that are close to the pelviureteric junction due to the risk of retropulsion of the stone into the kidney.

Prostate cancer screening: what do men know, think and do about their risk? exploring the opinions of men in an urban area in Lagos State, Nigeria: a mixed methods survey.

INTRODUCTION: Prostate cancer (PCa) is the leading cause of cancer-related deaths in men aged 40 years and older. Incidence and mortality rates are higher in African men. PCa is amenable to early detection by screening which can prevent and reduce cancer deaths. Late-stage presentation and diagnosis often occur due to poor screening practices. This study assessed the knowledge, attitude, prevalence and barriers towards PCa screening among males in an urban area in Nigeria using a mixed method approach. METHODS: This cross-sectional descriptive study used quantitative and qualitative methods among men aged 40 years and older. A pretested structured questionnaire was used to interview 344 respondents through multi-stage sampling. Additionally, two focus group sessions were held using a pre-tested guide. RESULTS: Respondents were between 40-89 years with a mean age of 52.8 ± 9.9 years. Majority (54.9%) had poor knowledge of prostate cancer and its screening methods however, 65.7% expressed positive attitudes towards screening. Only 73 (21.2%) had ever been screened. The focus groups showed that respondents expressed a willingness to undergo PCa screening. The main barriers to screening were the fears of a positive result, ignorance and financial constraints. Participants preferred male physicians during digital rectal examinations. CONCLUSION: Respondents showed poor levels of knowledge. They expressed positive attitudes towards screening. However, this was not translated into practice. Public health interventions should educate men about benefits of early detection while addressing fears of positive findings and gender biases during rectal examinations. Efforts at providing low-cost alternatives for PCa screening are needed.

Transabdominal repair of vesicovaginal fistulae: A 10-year tertiary care hospital experience in Nigeria.

BACKGROUND: Vesicovaginal fistula (VVF) is still a major cause for concern in many developing countries. Arguments continue as to the best approach for repair. This study aimed to present our experience with transabdominal VVF repair. SUBJECTS AND METHODS: This was a 10-year retrospective review of transabdominal VVF repair. Important data extracted from the case notes included patients' demography, aetiology, previous repair, operative findings, procedures and treatment outcome. Data were analysed using SPSS version 21. Bivariate analysis of factors affecting treatment outcome was carried out with the level of significance set at P < 0.05. RESULTS: Fifty-three VVF repairs were carried out in 51 patients. Mean age was 29.8 ± 15.4 years. Forty-five (84.9%) had previous repairs. The aetiologies of VVFs were prolonged obstructed labour in 41 (80.4%) and post-operative in 10 (19.6%). Forty-one repairs were through a transperitoneal transvesical approach whereas 12 had an extraperitoneal transvesical approach. The fistulae diameter ranged from 0.3 to 2.8 cm with an average of 1.64 cm. Six had ureteric re-implantation; (bilateral in two patients). Repair was successful in 47 (88.7%) cases, which translated to the overall success rate of 92.1% in the 51 patients treated. Success rate was higher (95.6%) for the subset of patients who had previous transvaginal repairs. Catheter blockage in the post-operative period was a significant factor that had effect on outcome (P < 0.015). CONCLUSION: Transabdominal repair recorded an excellent result in patients who had previously failed transvaginal repairs and may be considered as the first option in these patients.
