The use of 3D digital anatomy model improves the communication with patients presenting with prostate disease: The first experience in Senegal.

OBJECTIVES: We hypothesized that the use of an interactive 3D digital anatomy model can improve the quality of communication with patients about prostate disease. METHODS: A 3D digital anatomy model of the prostate was created from an MRI scan, according to McNeal's zonal anatomy classification. During urological consultation, the physician presented the digital model on a computer and used it to explain the disease and available management options. The experience of patients and physicians was recorded in questionnaires. RESULTS: The main findings were as follows: 308 patients and 47 physicians participated in the study. In the patient group, 96.8% reported an improved level of understanding of prostate disease and 90.6% reported an improved ability to ask questions during consultation. Among the physicians, 91.5% reported improved communication skills and 100% reported an improved ability to obtain patient consent for subsequent treatment. At the same time, 76.6% of physicians noted that using the computer model lengthened the consultation. CONCLUSION: This exploratory study found that the use of a 3D digital anatomy model in urology consultations was received overwhelmingly favorably by both patients and physicians, and it was perceived to improve the quality of communication between patient and physician. A randomized study is needed to confirm the preliminary findings and further quantify the improvements in the quality of patient-physician communication.

Design of an Ultrasound-Navigated Prostate Cancer Biopsy System for Nationwide Implementation in Senegal.

This paper presents the design of NaviPBx, an ultrasound-navigated prostate cancer biopsy system. NaviPBx is designed to support an affordable and sustainable national healthcare program in Senegal. It uses spatiotemporal navigation and multiparametric transrectal ultrasound to guide biopsies. NaviPBx integrates concepts and methods that have been independently validated previously in clinical feasibility studies and deploys them together in a practical prostate cancer biopsy system. NaviPBx is based entirely on free open-source software and will be shared as a free open-source program with no restriction on its use. NaviPBx is set to be deployed and sustained nationwide through the Senegalese Military Health Service. This paper reports on the results of the design process of NaviPBx. Our approach concentrates on "frugal technology", intended to be affordable for low-middle income (LMIC) countries. Our project promises the wide-scale application of prostate biopsy and will foster time-efficient development and programmatic implementation of ultrasound-guided diagnostic and therapeutic interventions in Senegal and beyond.

[Results of two-level urethroplasty according to Bengt Johanson for complex urethral strictures in adults]. / Resultats de l'uretroplastie en deux temps selon Bengt Johanson pour les stenoses uretrales complexes de l'adulte.

AIM: to evaluate the results of two-level urethroplasty in the treatment of complex urethral strictures in our clinical center. PATIENTS AND METHOD: Thiswas a retrospective cross sectional study from January 2012 to September 2015 in our clinical center. Patients operated according to Bengt Johanson technique were included. The parameters studied were age, the urological history, consultation reasons, duration of evolution, stenosis characteristics and treatment outcomes. RESULTS: twelve patients were enrolled in our study. The mean age was 48 ± 20 years. The main reason consultation reason is urine retention. The mean duration of evolution was 30 ± 25 months. The most common etiology identified was scleroinflammatory one . All the patients already had at least one medical background. The physical examination showed a periurethral gangue in 10 patients. The mean length of the urethral stricture was 6.3 ± 2.2 cm. After an average follow-up of 3.8 ± 2.3 months; the treatment outcomes were considered satisfactory in 8 patients and bad in 4 patients. CONCLUSION: Bengt Johanson's two level urethoplasty gives good outcomes in the treatment of complex urethral strictures.

[Outcomes of radical prostatectomy in patients with prostate cancer at the Aristide Le Dantec University Hospital]. / La prostatectomie radicale: résultats carcinologiques au Centre Hospitalier Universitaire Aristide Le Dantec.

The purpose of this study was to assess outcomes of radical prostatectomy in patients with prostate cancer. We conducted a retrospective single-center study in the Department of Urology and Andrology at the Aristide Le Dantec Hospital in Dakar from June 1, 2010 to May 31, 2016. We collected data of 60 patients undergoing radical retropubic prostatectomy associated with dissection of the iliac and obturator nodes. After radical prostatectomy, prostate specific antigen (PSA) levels were undetectable (<0.1 ng/mL) in 20 patients (33.3%). Eleven patients (18.3%), who had biochemical relapse, received complementary hormone therapy. Patients achieved a response after initiation of treatment, and total PSA became undetectable again after an 8-month follow-up period. Mean overall survival was 17.5 months, with a median of 9.49. Cumulative overall survival rates at 1 year, 3 years and 4 years were 42.4, 13.6 and 6.8%, respectively. Mean relapse-free survival was 17.3 months, with a median biochemical relapse-free survival of eleven (11) months. The mean duration of specific survival was 8.1 months, with a median of 3 months. Seven patients had positive resection margins (11.6%). Four patients had lymph node involvement. Radical prostatectomy, suggested in some patients with prostate cancer in our practice, has been shown to be an effective therapeutic method leading to good outcomes.

Affordable Custom Three-Dimensional Anatomy Atlases.

In this paper, we present methodology and tools for creating custom three-dimensional anatomical atlases for medical education based on web technologies and open-source software. Traditional medical anatomy education has relied on printed anatomical atlases, in-person lectures, and anatomical dissection. This traditional approach underserves populations in need due to high cost, lack of availability of materials, and a limited of trained educators. Open and free online anatomical atlases developed by an international community of experts help remedy these shortcomings, more fully addressing the sustainable development goals of quality education and good health at a global scale. We have developed a web application, the Atlas Assembly Tool, that assists medical professionals in assembling atlases for open dissemination throughout the world. Our tool aims to complement existing open source medical projects such as 3D Slicer and the Open Anatomy Browser to provide a pipeline from original medical image data to web-browsable atlases suitable for medical education. Our development is an integral part of the European INTERREG MACbioIDi project, promoting sustainable development through technology-based medical education and training in close collaboration with partners in Europe, Africa and the United States.

Impact of tumor cytoreduction in metastatic prostate cancer.

Objective: To assess the impact of tumor cytoreduction on cancer outcomes and patient survival in metastatic prostate cancer. Patients and methods: It is a prospective study spanning a two-year period between October 1st 2015 and March 31st 2017. We enrolled 102 cases of metastatic hormone-sensitive prostate cancer. Fifty-seven (57) patients had exclusively androgen deprivation therapy (ADT) (group 1) and 45 had, in addition, an open prostatectomy or Transurethral resection of the Prostate (group 2). We compared both groups using the total PSA nadir, the time to PSA nadir, the overall survival (OS), and the progression-free survival (PFS). Results: The average nadir PSA was lower for the tumor cytoreduction group (16.8±1.6 ng/mL (0.01-193.5) versus 110.7±17.9 ng/mL (0.01-1379)). Median time to PSA nadir was shorter in patients in the ADT only group (8 months vs 3 months (p=0.025)). The OS was shorter in patients treated with ADT only compared to the tumor cytoreduction group (median 14 months vs 24 months, respectively (p=0.03)). Similarly, tumor cytoreduction had a positive impact on patient progression (median PFS 20 months (group 1) vs 43 months (group 2)). Conclusion: Tumor cytoreduction has a positive impact on the oncological results and the survival of patients under ADT.

[Testicular cancer is a rare condition in black people. We report 5 cases of testicular cancer in men with undescended testis]. / Cancer sur testicule non descendu intra-abdominal. A propos de 5 cas.

PATIENTS AND METHODS: We underwent a retrospective study of five cases of testicular cancer in undescended testis. The parameters of study were: age at diagnosis, circumstances of diagnosis, values of tumour markers, and pathological aspects of tumours after removal. The data were studied using the medical records of patients. RESULTS: Mean age was 30, 6 years (27; 34). Only 1 patient had a child at the time of diagnosis. All patients came to our clinic for a general state impairment associated to an abdominal palpable mass. The increase of the value of tumour markers was not constant. A capsular effraction was found in 3 cases with a rupture into the peritoneum. The pathology exam found 3 embryonic carcinoma and 2 seminomas, a lymph node involvement was found in 3 cases. CONCLUSION: The scarcity of these tumours should not make us ignore them. The early diagnosis of the tumour can be facilitated by testicular descent, because even if the descent of the testis does not prevent the tumour it can ease the follow-up.

[Leiomyosarcoma of the spermatic cord]. / Le léiomyosarcome du cordon spermatique.

Leiomyosarcomas of the spermatic cord are rare tumours. The authors report the case of a 65-year-old man presenting with painful mass of the left side of the scrotum with scrotal ulceration. Left transinguinal orchidectomy and left hemiscrotectomy were performed and histological examination of the operative specimen revealed leiomyosarcoma of the spermatic cord. No metastases were observed on thoracoabdominopelvic CT. One month after discharge from hospital, the patient presented with delayed healing and complementary scrotal resection and adjuvant radiotherapy were performed. Local and regional extension is frequently observed in leiomyosarcoma of the spermatic cord, justifying radical transinguinal orchidectomy with high ligation of the cord. Cases at greatest risk of recurrence (large tumour, early local recurrence, positive surgical margins) should be identified by multidisciplinary committees and may be eligible for adjuvant radiotherapy.

Cure de varicocèle sous anesthésie locale: aspects techniques et faisabilité / Varicocele surgery under local anesthesia: technical aspects and feasibilty

Contexte et objectif. Au Sénégal, la chirurgie de la varicocèle, occupe une place non négligeable dans la prise en charge de l'infertilité masculine. Cette chirurgie connait une utilisation de plus en plus fréquente de la voie inguinale ou même sous inguinale. Cette modification progressive des habitudes a été l'origine de l'étude de la faisabilité et de la sécurité de l'anesthésie locale dans notre pratique. Méthodes. Dans une série des cas, trente-cinq (35) patients ayant donné leur consentement ont été opérés sous anesthésie locale selon le même protocole par les médecins de l'équipe. Résultats. L'âge moyen des patients était de 32,5 ± 8 ans (18-54 ans). Le motif de consultation le plus fréquent était l'infertilité du couple (62,9 %). Vingt-deux patients avaient une varicocèle bilatérale et treize une varicocèle unilatérale. Tous nos patients étaient classés ASA I. La moyenne de la durée d'intervention était de 22 ± 9,48 min. La moyenne du degré de la douleur pendant l'opération était à 1,37/10 selon l'EVA chez les 35 patients. Aucun incident peropératoire lié à l'anesthésie ou à un problème technique chirurgical n'a été observé. Après la chirurgie, 94,3% ont déclaré avoir été satisfait du geste. Conclusion. La pratique de la chirurgie ambulatoire sous anesthésie locale de la varicocèle offre une part importante dans la prise en charge de cette affection

Context and objective. In Senegal, varicocele surgery occupies a significant place in the management of male infertility. This surgery is increasingly performed via the inguinal or even sub inguinal route. This gradual change in habits was the origin of the study of the feasibility and safety of local anesthesia in our practice. Methods. In a cross sectional study, thirty-five (35) patients who gave their consent underwent the surgery under local anesthesia according to a standardized protocol by the team's doctors. Results. The average age of the patients was 32.5 ± 8 years (18-54 years). The most frequent reason for consultation was infertility in the couple (62.9%). Twenty-two patients had bilateral varicocele and thirteen had unilateral varicocele. All our patients were classified as ASA I. The average duration of the operation was 22 ± 9.48 min. The average degree of pain during the operation was 1.37/10 according to the Visual analog Scale in the 35 patients. No intraoperative incident related to anesthesia or a surgical technical problem was observed. After surgery, 94.3% said they were satisfied. Conclusion. The practice of outpatient surgery under local anesthesia for varicocele occupies an important part in the management of this condition.

[Review of the management of enuresis in a Senegalese hospital]. / Réflexions sur la prise en charge de l'énurésie dans un centre hospitalier au Sénégal.

The profile of enuretic patients consulting a hospital urology department was reviewed over a period of 15 months based on 102 cases. The study concerned 47 male subjects and 55female subjects with a mean age of 15 +/- 5.3 years. The mean weekly frequency of enuresis was 5.2 +/- 1.9 and enuresis occurred more than once a night for 41.6% of patients. Enuresis was primary in almost 67% of cases. Various aetiological factors for enuresis were identified from analysis of the clinical data and were generally associated: sleep factor (n=93), bladder factor (n=84), hormonalfactor (n=52). Patients were managed as a function of the factors identified. With a mean follow-up of 6 +/- 2.1 months, cure was obtained in 30.4% of cases and improvement was obtained in 24.5%. The various management problems are discussed as a function of socio-economic realities in Senegal and the authors emphasize the need for a multifactorial approach.

[Complications of circumcision. Report of 63 cases]. / Les complications de la circoncision. A propos de 63 cas.

OBJECTIVE: The aim of this study was to report complications of circumcision received in urologic center. MATERIAL AND METHODS: From a retrospective study during a period of 11 years, 63 cases of complications were noticed secondary to traditional circumcision (n = 45) or paramedics (n = 18). RESULTS: The different complications were: urethral fistulas (n = 41), total or partial glans amputation (n = 9), urethral stricture of the meatus (n = 8), penile pseudo elephantiasis (n = 2), penile denudation (n = 1), hemorragiae (n = 6) and septicaemia (n = 1). The authors underline clinical aspects of these complications and the problems of their treatment.

Renal cell carcinoma with MiTF/TFE3 translocation in children: report of a case at the stage of lymph node involvement.

Renal cell carcinoma (RCC) is rare in children. Unlike nephroblastoma, however, it does not respond well to chemoradiotherapy. Its treatment is therefore based on surgical removal of the tumour. However, lymphadenectomy for RCC is controversial, and its prognosis is unclear. The authors report a case of RCC with MiTF/TFE3 translocation at the stage of lymph node involvement without metastasis in a boy of age 12, who was treated with radical nephrectomy and limited lymphadenectomy. This tumour constitutes a newly individualised entity in the World Health Organization's 2004 classification. Eighteen months after the operation, the patient was presented with no sign of recurrence. This case aids in showing that lymph node involvement in RCC with translocation in children is not associated with a poor prognosis and that lymphadenectomy during surgery for enlarged nephrectomy is essential.

Etiology and current clinical characteristics of male urethral stricture disease: experience from a public teaching hospital in Senegal.

OBJECTIVE: To identify the etiology and current clinical characteristics of male urethral stricture disease (USD) in Senegal. PATIENTS AND METHODS: A retrospective and mono-centric study over a 10-year period (between January 1999 and December 2008) was carried out and included all male patients with USD admitted to the Urology Department of Aristide Le-Dantec Hospital (Dakar). RESULTS: We recorded 414 USD cases. The maximum annual incidence was observed in 2004, and from then, the incidence tended to decrease gradually. The mean age of patients was 43.7 ± 19.6 years (1-89 years), and 43% of patients were younger than 40 years old. The mean time from symptoms onset to the consultation was 20.1 ± 24.9 months (1-120 months). Most patients (42.2%) were admitted because they suffered dysuria. In 57.8% of patients, USD was diagnosed with complications. The most common site of stricture was at the bulbar urethra (72.7%). The length of the urethral stricture was smaller than 1 cm in 59.6% of patients, between 1 and 3 cm in 28.5% and between 3 and 5 cm in 7.7%. The stricture was longer than 5 cm in eight patients and was staged (multifocal) in nine patients. The etiology of urethral stricture was infectious in 63% of patients, traumatic in 13.7% and iatrogenic in 8.2%. The etiology was not identified in 14.9% of cases. The infectious etiology was urethritis in 259 cases and urogenital schistosomiasis in 12 cases. A study of the etiology according to stricture site showed that bulbar USD was infectious in 77.7% of cases and that all membranous USD cases were traumatic. CONCLUSION: Male urethral stricture in Senegal is often a sequela of gonococcal urethritis and is frequently detected because of infectious complications such as gangrene of the genitalia or urinary tract infections. Its prevention in this geographical region thus requires fighting against sexually transmitted infections and treating appropriately and effectively all urethritis.
