RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

The most commonly used long-term reversible female contraception is intrauterine contraceptive device (IUCD). Its use is however associated with documented complications. Uterine perforation, though rare, is arguably the most surgically important of all these complications. We report a case of a 48-year-old para 4+0 (4 alive) woman who had IUCD insertion 17 years earlier and had forgotten she had the device having had two children thereafter. The IUCD was subsequently translocated through the dome of the bladder into the peritoneal cavity with calculus formation around the tail and thread of the IUCD in the urinary bladder causing recurrent urinary tract infection. This "Collar Stud" effect made either cystoscopic or laparoscopic retrieval alone unsuccessful necessitating a combined approach. This case report highlights the need for a combined laparoscopic and cystoscopic approach in the retrieval of the unusual presentation of translocated IUCD.

RESUMEN

OBJECTIVE: The objective of this study was to assess the efficacy of tamsulosin and finasteride monotherapies, and their combination in men with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: This is a prospective single-blind randomized study of ninety men with BPH who were managed using drugs. The International Prostate Symptom Score (IPSS), peak urinary flow rate, and prostate volume were measured as parameters for assessment at the beginning, 3 months, and 6 months of the study. RESULTS: The mean age of patients was 61.65 with a range of 44-81 years. There was a progressive and sustained improvement in the IPSS score in all patient groups with mean decrease at 3 months of 7.24 (42.59%), 7.60 (41.85%), and 7.24 (40.61%) and at 6 months of 8.14 (47.88%), 10.33 (56.88%), and 11.1 (62.25%) in the tamsulosin, finasteride, and combination groups, respectively. There was an increase in peak urinary flow rate in all groups with mean increase at 3 months of 0.98, 0.05, and 3.55 (ml/s) and at 6 months of 4.11, 0.87, and 3.74 (ml/s) in the tamsulosin, finasteride, and combination groups, respectively. There was a reduction in the prostate volume in the finasteride and combination groups at 6 months of 6.8 and 6.32 cm3, respectively, while the tamsulosin group recorded an increase. CONCLUSION: At the end of 6 months, tamsulosin monotherapy and combination therapy appear to be equally effective in the treatment of lower urinary tract symptoms BPH while finasteride monotherapy appears to be the least effective. Bothersome, side effects were more in patients taking finasteride alone or as combination therapy.

RESUMEN

AIM AND OBJECTIVES: The aim of this study is to compare the prostate cancer detection rates of sextant and extended transrectal ultrasound (TRUS)-guided fine-needle aspiration biopsy (FNAB) protocols. MATERIALS AND METHODS: This was a prospective study of 96 patients investigated for prostate cancer. An extended 10-aspiration TRUS-guided FNAB using a 22G Echotip Chiba needle was performed. Inclusion criteria included the presence of one or more of the following: Abnormal digital rectal examination (DRE) findings, persistently elevated prostate specific antigen, and abnormal prostatic imaging. A set of traditional sextant aspirations were carried out as well as four laterally guided aspirations taken from the middle base of the peripheral zone on either side. The cancer detection rates of sextant and extended (combination of sextant and lateral) FNAB protocols were determined and compared. The value of P < 0.05 was considered statistically significant. RESULTS: The overall cancer detection rate was 24%. Benign cases were reported in 71.8% of patients and 4.2% reported as suspicious. Of the 23 patients' aspirations positive for malignancy, 16 (69.6%) were detectable by the sextant protocol while the lateral protocol detected 21 (91.3%). Two cancers were detected by the sextant protocol only (where the lateral technique was negative for malignancy), 7 cancers were detected by the lateral protocol only while 14 cancers were positive in both the sextant and lateral protocols. The extended protocol showed a statistically significant 30.4% increase in cancer detection over the traditional sextant (P = 0.007). CONCLUSION: The extended protocol rather than the sextant protocol should be offered to patients who require FNAB of the prostate as the optimum FNAB protocol.

RESUMEN

AIMS AND OBJECTIVE: This study aims at correlating different digital rectal examination (DRE) abnormalities with histopathological results in patients with prostatic diseases. MATERIALS AND METHODS: A prospective study of 236 patients who underwent prostate needle biopsy (PNB). Inclusion criteria were presence of abnormal DRE findings or elevated prostate specific antigen above 4 ng/ml or both. They all had 10-core extended transrectal biopsy and specimens were sent for histopathological examination. Correlations were made between DRE findings and histopathology results. Two separate multivariate logistic regression models were created; the first evaluated the relationship of predictors (DRE findings) to the likelihood of detecting cancer and the second explored predictors of high-grade cancer on PNB. RESULTS: Two hundred and thirty-six patients were enrolled with a mean age of 66.9 years and range of 43-90 years. Histopathology results were malignant in 102 (43.2%) and benign in 134 (56.8%). Ninety-one (38.6%) and 145 (61.4%) had normal DRE and abnormal DRE findings with cancer detection rates of 23.1% and 55.8% respectively. Nodular prostate is the most common abnormality in 63.4% patients with abnormal DRE. Each sign of DRE had different predictive value with enhanced positive predictive value when combinations of abnormalities are present. Abnormal DRE is an independent predictor of high-grade tumor. Mean Gleason scores were 4.7 and 7.1 in patients with normal and abnormal DRE respectively. CONCLUSION: DRE is a useful and important tool in assessing patients with suspected prostate diseases who need prostate biopsy. An abnormal DRE correlated well with prostate cancer and independently predicted high-grade disease in these men.

RESUMEN

OBJECTIVE: To present our recent experience in the management of penile fracture. PATIENTS AND METHODS: We present 21 cases of penile fracture managed at the two Federal-owned tertiary hospitals in two neighbouring states in south-west Nigeria between 2001 and 2011. The diagnosis was based mainly on a clinical evaluation. The treatment was surgical in patients who presented within 2 weeks of the fracture. The emphasis during the follow-up was on erectile function and micturition. RESULTS: Seventeen patients presented within 48 h, two presented after a week, while two reported months later with penile deviation. The mean age of the patients was 26.4 years. The cause of fracture was sexual intercourse in 11 (52%) patients and forceful manipulation of the erect penis in 10 (48%). Thirteen (62%) of all injuries occurred in the last 2 years of the study, of which eight men were injured during rear entry with the woman on top (reverse coital) position. Six of the patients with reverse coital injuries reported trying the position after watching it on the Internet, specifically on their cellular phones. Eighteen patients had surgical treatment, with a satisfactory outcome. Two of the other three patients had penile deviation during erection. CONCLUSIONS: The incidence and causes of penile fracture appear to have changed drastically over the last 2 years in our environment. The rapid demographic changes in south-west Nigeria are probably responsible. There appears to be a relationship between the cause of fracture and the use of the Internet, although that might be coincidental. Surgical repair, irrespective of the delay before intervention, usually offers a satisfactory outcome.
