Place of urolithiasis in the spectrum of urological pathologies, practices and use of endourological procedures in the management of calculi of the upper urinary tract: results of a survey of referral centres in Africa.

Our aim was to determine the current trend of endourology in the management of upper urinary tract calculi in Africa reference centres. We conducted an online multiple-choice questionnaire survey involving 46 centres from 27 countries using a structured well-designed Google Form (®) questionnaire. The questionnaires were distributed to the head of service through their emails. The questions collected demographic data about the centre, the epidemiology of urolithiasis, diagnostic means and management of upper urolithiasis, especially access to endourology procedures and their practices. Descriptive analyses were performed. The participation rate was 77.9%. Urinary lithiasis was one of the three main pathologies encountered in 42/46 centres. 33 centres had easy access to CT scanners and 34 had operating theatres equipped with endo-urological surgery equipment. Of these 34 centres, 30 perform endourology for the management of upper urinary tract stones. Rigid ureteroscopy is the main technique used by the centres. It is the only endourology technique used for stone management by 12 centres (40%). 7/30 (23.3%) have the option of performing rigid ureteroscopy, flexible ureteroscopy and percutaneous nephrolithotomy. The frequency of procedures varies widely, with 43.3% rarely performing endourological surgery. Seventeen centres have their operating theatre equipped with a fluoroscope and 6/42 centres have extracorporeal lithotripsy. Open surgery is still used in 29/42 centres (69.1%). Laparoscopy is available in 50% of centres, but none reported performing laparoscopic lithotomy. In Africa, urinary lithiasis plays an important role in the activities of referral centres. Modern management techniques are used to varying degrees (not all centres have them) and with very variable frequency. Open surgery is still widely performed as a management. Rigid ureteroscopy is the main endourological technique. It is essential to develop the practice of modern urology in Africa, mainly endourology.

Dissemination and implementation of an evidence-based voluntary medical male circumcision program: The Spear & Shield program.

Despite compelling evidence linking voluntary medical male circumcision (VMMC) with 60-70% HIV risk reduction in sub-Saharan Africa, Zambian men have been especially reluctant to undergo VMMC. The Government of Zambia set targets for VMMC uptake and promoted community-level interventions. Spear & Shield (S&S) is an innovative, evidence-based, service program promoting VMMC uptake while ensuring both VMMC supply and demand. This study assessed the large-scale provincial rollout of the program (S&S2) utilizing the RE-AIM model for translating interventions into the community. The S&S2 study was conducted between November 2015 and December 2020, and sequentially rolled out over four Zambian provinces in 96 clinics; 24 observation clinics received VMMC training only. Local clinic healthcare workers were trained to conduct the VMMC procedure and HIV counselors were trained to lead S&S group sessions. Using the RE-AIM model, primary outcomes were: Reach, the number, proportion, and representativeness of S&S attendees; Effectiveness, the impact of S&S2 on VMMC uptake; Adoption, the number, proportion, and representativeness of clinics implementing S&S2; Implementation, fidelity to the S&S intervention manual; and Maintenance, the extent to which S&S2 became an element of standard care within community clinics. Initially, n = 109 clinics were recruited; 96 were sustained and randomized for activation (Adoption). A total of 45,630 clinic patients (n = 23,236 men and n = 22,394 women) volunteered to attend the S&S sessions (Reach). The S&S2 program ran over 2,866 clinic-months (Implementation). Although the study did not target individual-level VMMCs, ~58,301 additional VMMCs were conducted at the clinic level (Effectiveness). Fidelity to the S&S intervention by group leaders ranged from 42%-95%. Sustainability of the program was operationalized as the number of CHCs initially activated that sustained the program. Intervention delivery ended, however, when study funding ceased (Maintenance). The S&S2 program successfully utilized the RE-AIM model to achieve study goals for implementation and dissemination in four Zambian provinces. Innovative VMMC programs such as S&S2 can improve the uptake of VMMC, one of the most effective strategies in the HIV prevention arsenal.

Factors influencing neonatal male circumcision uptake among expecting couples in Zambia: formative findings.

Male circumcision is a protective HIV prevention strategy. However, uncircumcised Zambian men are reluctant to undergo voluntary medical male circumcision (VMMC). Tailored interventions are necessary to stimulate the uptake of early infant male circumcision (EIMC) and VMMC in Zambia. This feasibility study presents the formative process of utilising the PRECEDE framework in the development of a family-centred EIMC/VMMC intervention, Like Father Like Son, and its application in an existing VMMC intervention, Spear & Shield. We found that fear of the pain associated with EIMC procedures, foreskin disposal, beliefs in children's autonomy and rights, and men's dominance in health decision-making were factors affecting EIMC uptake. Perceived benefits for infants included improved hygiene, protection from HIV infection, and faster recovery. Reinforcing factors included female partners and fathers' MC status. The availability and access to EIMC services and information, skill and experience of health workers, and engagement and belief in traditional circumcision practices were factors enabling EIMC uptake. These individual, interpersonal, and structural factors positively and negatively influencing EIMC uptake in the Zambian clinic context were integrated into the intervention for expecting parents. Feedback from community advisory boards suggested the process was effective in developing a culturally tailored and acceptable EIMC/VMMC promotion intervention.

Increasing early infant male circumcision uptake in Zambia: Like father like son.

Voluntary Medical Male Circumcision (VMMC) is an effective strategy for HIV prevention in areas with high prevalence of, and risk for, HIV. More than 361,000 male neonates are born each year in Zambia, many of whom could be eligible for Early-Infant Medical Circumcision (EIMC). Building on successful implementation strategies utilized in our Spear & Shield program, this pilot study, "Like Father, Like Son" (LFLS), evaluated the feasibility and acceptability of offering combined EIMC and VMMC services and couple-level behavioral interventions. A total of N = 702 pregnant women and their male partners (n = 351 couples) were recruited and enrolled. Couples were assessed twice pre-birth, 2 weeks post birth, and 6 months post birth. Expectant mothers were an average of 15.05 weeks pregnant (SD = 8.83). Thirty-nine pregnancies did not result in a live birth (11%), 14 couples withdrew from the study or were lost to follow-up prior to delivery (4%), and 148 babies were born female (42%), leaving 150 couples with a male infant in the analytic sample (43%). The LFLS study achieved significantly higher EIMC rates (35%) in comparison with previously observed EIMC study rates in Zambia (11%), and significantly higher than hypothetical comparison rates up to 30%. Relative to baseline rates, odds of VMMC among couples' older sons increased by 31% at post-intervention and by 90% at two-weeks following birth. Overall, this pilot study found the LFLS intervention to be feasible, acceptable, and effective in doubling the rate of EIMC in comparison with a previous longitudinal study in Zambia. Future research should consider a family-centric approach to promotion of male circumcision for infants and adolescents. LFLS may be effective in promoting father-son "bonding" by MC status; a bond that may be a bridge to increase both EIMC and VMMC uptake in newborns and couples' older sons and is a novel leverage point for promotion of this HIV prevention strategy.

Zambian Parents' Perspectives on Early-Infant Versus Early-Adolescent Male Circumcision.

Despite increasing interest in Early-Infant and Early-Adolescent Medical Circumcision (EIMC and EAMC, respectively) in Zambia, parental willingness to have their sons undergo the procedure has not been explored. This study describes Zambian parents' perspectives on EIMC and EAMC. A total of N = 600 men and women (n = 300 couples) were recruited. Most parents, 89% and 83%, planned to have their newborn or adolescent sons circumcised, respectively, and 70% and 57% had plans for EIMC and EAMC, respectively. Most (91% for infants and 86% for adolescents) reported they were considering the pros and cons of circumcision. Parents' age (OR 1.05), having children living in one's home (OR 3.58), and lower education (OR 0.63) were associated with sons' circumcision. The minimal risks associated with circumcision and the lifetime benefits conferred underscore its contribution to public health in high HIV prevalence areas.

RESUMEN: A pesar del creciente interés en la Circuncisión Médica Temprana de Niños y Adolescentes (EIMC y EAMC, respectivamente, por su siglas en ingles) en Zambia, no se ha explorado la voluntad de los padres, de dar consentimiento, para que sus hijos se sometan al procedimiento. Este studio, describe las perspectivas de los padres de Zambia sobre EIMC y EAMC. Se reclutaron un total de N = 600 hombres y mujeres (n = 300 parejas) que esperaban tener un hijo. La mayoría de los padres, 89% y 83%, planeaban circuncidar a sus hijos recién nacidos o adolescentes, respectivamente, y 70% y 57% tenían planes para EIMC y EAMC, respectivamente. La mayoría (91% para bebés y 86% para adolescentes) informaron que estaban considerando las ventajas y desventajas de la circuncisión. La edad de los padres (OR 1,05), tener hijos viviendo en el hogar (OR 3,58) y menor educación (OR 0,63) se asociaron con la circuncisión de los hijos. Los riesgos mínimos asociados con la circuncisión y los beneficios conferidos de por vida subrayan su contribución a la salud pública en áreas de alta prevalencia del VIH.

Dissemination of the Spear & Shield Project using a Training of Trainers Model: A reflection on challenges and successes.

Several large-scale clinical trials have conclusively demonstrated that voluntary medical male circumcision (VMMC) could provide a 50%-70% reduction in HIV acquisition, but willingness to undergo VMMC has been lowest in Zambia compared to other countries in eastern and southern Africa. This manuscript describes training for "task-shifting" among local healthcare workers at Community Health Centers (CHCs) applying state of the art strategies (e.g., Training of Trainers, i.e., ToT, and Training of Facilitators, ToF) to provide novel clinical services. Staff at 96 CHCs from four Provinces in Zambia were sequentially trained to provide the Spear & Shield intervention. A total of 45,630 men (n = 23,236) and women (n = 22,394) volunteered to participate in the S&S intervention service program when offered in the CHCs. Group session (total = 5313 sessions; 2,736 men's and 2,582 women's sessions) were conducted over 4.5 years. Remarkably, both men and women's groups achieved 97% retention. Of these, 256 sessions recorded from 128 group leaders were assessed and scored for intervention fidelity; fidelity was 80%-90% among the majority of clinics. S&S program sustainment exceeded expectations among 85% of clinics (82/96) in all provinces across the duration of the study. Of note, attendance in the S&S program was encouraged by CHC staff, but no financial incentives were provided to those attending S&S. This study examined the effectiveness of the ToT/ToF model in dissemination of the S&S program, which proved to be feasible even in resource-limited settings. Benefits and challenges are discussed.

Antisperm Antibody Testing: A Comprehensive Review of Its Role in the Management of Immunological Male Infertility and Results of a Global Survey of Clinical Practices.

Antisperm antibodies (ASA), as a cause of male infertility, have been detected in infertile males as early as 1954. Multiple causes of ASA production have been identified, and they are due to an abnormal exposure of mature germ cells to the immune system. ASA testing (with mixed anti-globulin reaction, and immunobead binding test) was described in the WHO manual 5th edition and is most recently listed among the extended semen tests in the WHO manual 6th edition. The relationship between ASA and infertility is somewhat complex. The presence of sperm agglutination, while insufficient to diagnose immunological infertility, may indicate the presence of ASA. However, ASA can also be present in the absence of any sperm agglutination. The andrological management of ASA depends on the etiology and individual practices of clinicians. In this article, we provide a comprehensive review of the causes of ASA production, its role in immunological male infertility, clinical indications of ASA testing, and the available therapeutic options. We also provide the details of laboratory procedures for assessment of ASA together with important measures for quality control. Additionally, laboratory and clinical scenarios are presented to guide the reader in the management of ASA and immunological male infertility. Furthermore, we report the results of a recent worldwide survey, conducted to gather information about clinical practices in the management of immunological male infertility.

Prevalence and correlates of voluntary medical male circumcision adverse events among adult males in the Copperbelt Province of Zambia: A cross-sectional study.

BACKGROUND: Voluntary Medical Male Circumcision (VMMC) is a key intervention in HIV/AIDS. Improving VMMC program uptake in Zambia requires careful monitoring of adverse events (AE) to inform program quality and safety. We investigate the prevalence of VMMC AE and their associated factors among adult males in Ndola, Copperbelt Province, Zambia. METHODS: We performed a cross-sectional study using secondary clinical data collected in 2015 using two validated World Health Organisation/Ministry of Health reporting forms. We reviewed demographics and VMMC surgical details from 391 randomly sampled adult males aged ≥18 years at Ndola Teaching Hospital, a specialised VMMC fixed site in Zambia. Non-parametric tests (Fisher's exact test or Chi-square depending on assumptions being met) and logistic regression were conducted to determine the relationships between associated factors and VMMC AE. RESULTS: The overall VMMC AE prevalence was 3.1% (95% CI 1.60%- 5.30%) and most AEs occurred postoperatively. In decreasing order, the commonly reported VMMC AE included; bleeding (47.1%), swelling (29.4%), haematoma (17.6%), and delayed wound healing (5.9%). There was an inversely proportional relationship between VMMC volume (as measured by the number of surgeries conducted per VMMC provider) and AEs. Compared to the highest VMMC volume of 63.2% (247/391) as reference, as VMMC volume reduced to 35.0% (137/391) and then 1.8% (7/391), the likelihood of AEs increased by five times (aOR 5.08; 95% CI 1.33-19.49; p = 0.018) and then sixteen times (aOR 16.13; 95% CI 1.42-183.30; p = 0.025) respectively. CONCLUSIONS: Our study found a low prevalence of VMMC AEs in Ndola city, Copperbelt Province of Zambia guaranteeing the safety of the VMMC program. We recommend more surgically proficient staff to continue rendering this service. There is a need to explore other high priority national/regional areas of VMMC program safety/quality, such as adherence to follow-up visits.

Correlation of Internal Organ Weights with Body Weight and Body Height in Normal Adult Zambians: A Case Study of Ndola Teaching Hospital.

The objective of the research was to study the correlation of internal organ weights with body weight and length in normal adult Zambians. The study involved 114 (83 males and 31 females) forensic autopsies from Ndola Teaching Hospital done over a period of 12 months. The cases included autopsies of unnatural deaths including road traffic accidents and homicide. Cases where information about age and origin of the person was not available were left out of the study. The age of the decedents ranged from 16 to 85 years. The data was analyzed by Pearson correlation coefficient to determine correlation. P values less than 0.05 were considered to be statistically significant. It was observed that the heart, liver, left kidney, right kidney, brain, and left lung were positively correlated to body weight, while only the brain and the left lung were positively correlated to the height in the male population. In the female population, the heart, liver, right kidney, brain, and right lung were positively correlated to the weight of the body, while only the right kidney was positively correlated to the height of the body.

Accuracy of a "Single Question Nocturia Score" compared to the "International Prostate Symptoms Score" in the evaluation of lower urinary tract symptoms in benign prostatic hyperplasia: A study performed at Ndola Teaching Hospital, Ndola, Zambia.

INTRODUCTION: The International Prostate Symptom Score (IPSS) is a useful tool approved by the World Health Organisation and the American Urological Association to measure the severity of lower urinary tract symptoms (LUTS). Although commonly used in urological practice, the IPSS has faced many challenges in terms of its usage in developing countries. In our setting, most patients presenting with this condition are elderly patients with a low literacy level. Given this background, the IPSS could be time consuming and difficult to administer to such patients and it may lead to additional costs to the services. OBJECTIVES: The objective of this study was to compare the accuracy of a Single Question Nocturia Score (SQNS) with the IPSS in evaluation of lower urinary tracts symptoms in men with Benign prostatic hyperplasia(BPH). METHODS: The study was designed as a cross-sectional study using researcher-administered IPSS and SQNS questionnaires. The sensitivity, specificity, and correlation coefficient were used to compare the results obtained. Sensitivity was defined as the ability of the SQNS to detect severe-to-moderate symptoms, whereas specificity was defined as the ability of the SQNS to detect mild-to-no symptoms. RESULTS: We recruited 162 patients with an age range between 50 and 88 years. The mean age was 66.7 (standard deviation ± 8.97 years). The IPSS showed that 85 patients (52%) presented with mild symptoms, and 77 patients (48%) presented with severe-to-moderate symptoms. In contrast, the SQNS showed that 88 patients (54.3%) presented with mild symptoms and 74 patients (46.7%) presented with severe-to-moderate symptoms. The sensitivity of the SQNS was 91%, and the specificity was 87%. The correlation coefficient of the SQNS to IPSS using Pearson correlation coefficient, was 0.74. This study showed that in our setting, the SQNS may be used as an alternative to the IPSS in assessing the severity of LUTS in men with BPH especially in a busy clinic.

Preputial mucosal graft for urethral repair.

Urethral stricture disease is the commonest cause of morbidity in urology practice in sub-Saharan Africa. In contrast, prostate disease is commonly cited as the leading cause of urological disease in most urology practices in developed countries. In Africa, the aetiology of urethral stricture disease is compounded by a high prevalence of sexually transmitted infections (STIs), increasing levels of urethral trauma and over-stretched urological services. Thus, patients with prostate disease are treated with long-stay urethral catheters for periods often up to two years. This increases the risk of urethral stricture. The predominant aetiological factor is sexually transmitted infection due to gonococcus or chlamydia. This frequently leads to long severe strictures with spongiofibrosis, especially in the anterior urethra where the periurethral glands are located. These strictures respond poorly to urethral dilatation, optical urethrotomy or primary anastomosis. The majority of strictures in Africa are best treated by open substitution urethroplasty. The gold standard has been the use of buccal mucosa graft for this substitution procedure. This procedure poses a great challenge in most centres with limited resources. In these settings, we have found that the use of a dorsal onlay free preputial graft is easy to perform and gives good results.

Strengthening and expanding the capacity of health worker education in Zambia.

INTRODUCTION: Zambia is facing a chronic shortage of health care workers. The paper aimed at understanding how the Medical Education Partnership Initiative (MEPI) program facilitated strengthening and expanding of the national capacity and quality of medical education as well as processes for retaining faculty in Zambia. METHODS: Data generated through documentary review, key informant interviews and observations were analyzed using a thematic approach. RESULTS: The MEPI program triggered the development of new postgraduate programs thereby increasing student enrollment. This was achieved by leveraging of existing and new partnerships with other universities and differentiating the old Master in Public Health into specialized curriculum. Furthermore, the MEPI program improved the capacity and quality of training by facilitating installation and integration of new technology such as the eGranary digital library, E-learning methods and clinical skills laboratory into the Schools. This technology enabled easy access to relevant data or information, quicker turn around of experiments and enhanced data recording, display and analysis features for experiments. The program also facilitated transforming of the academic environment into a more conducive work place through strengthening the Staff Development program and support towards research activities. These activities stimulated work motivation and interest in research by faculty. Meanwhile, these processes were inhibited by the inability to upload all courses on to Moodle as well as inadequate operating procedures and feedback mechanisms for the Moodle. CONCLUSION: Expansion and improvement in training processes for health care workers requires targeted investment within medical institutions and strengthening local and international partnerships.

A Cross Sectional Study of the Prevalence of Preputial and Penile Scrotal Abnormalities among Clients Undergoing Voluntary Medical Male Circumcision in Soweto, South Africa.

OBJECTIVE: Medical device use is currently approved for males without preputial or major penile scrotal abnormalities for voluntary medical male circumcision (VMMC). We determined the prevalence of preputial abnormalities at a busy VMMC centre in Soweto, South Africa. METHODS: This was a cross-sectional record review at a high-volume VMMC centre in South Africa. We collated pre-circumcision demographic and genital examination findings from clients 8 years and older who had undergone VMMC from 01 May 2013 to 30 April 2014. Logistic regression was used to determine factors associated with preputial abnormalities. FINDINGS: During the review period, 6861 circumcisions were conducted and 37.1% (n = 2543) were 8-13 year olds. Median age was 15 years (IQR: 12-23 years). Fifteen percent (n = 1030) had preputial abnormalities or major penile scrotal abnormalities. Age-specific prevalence of preputial or major genital abnormalities were 27.3%, 10.6% and 6.0% in 8-13, 14-18 and > 18 year olds respectively. The odds of preputial or major penile scrotal abnormality were higher in younger clients aged 8-13 years (OR = 5.9; 95% CI = 4.8-7.1) and 14-18 years (OR = 1.9; 95% CI = 1.5-2.4) compared to older clients above18 years and in those testing for HIV outside our clinic network (OR = 1.9; 95% CI = 1.4-2.7). CONCLUSION: The high prevalence of preputial and penile scrotal abnormalities observed suggests a need for VMMC sites to provide for both open surgical and devices methods in the provision of VMMC services. This is especially so among young male subjects presenting themselves for VMMC services at the various sites being developed in sub Saharan African countries.

HIV-associated renal and genitourinary comorbidities in Africa.

With the recent massive scale-up of access to antiretroviral therapy (ART) in resource-limited countries, HIV has become a chronic disease with new challenges. There is mounting evidence of an increased burden of renal and genitourinary diseases among HIV-infected persons caused by direct HIV viral effects and/or indirectly through the development of opportunistic infections, ART medication-related toxicities, and other noncommunicable diseases (NCDs). We review the epidemiology of HIV-associated renal and urogenital diseases, including interactions with kidney-related NCDs such as hypertension, diabetes mellitus, and cardiovascular disease. We also examine the current evidence regarding the impact of HIV infection on the development of urogenital diseases. Highly advisable in sub-Saharan Africa are the establishment of renal disease registries, reviews of existing clinical practice including cost-effectiveness studies, and the adoption and use of HIV-related NCD management, with training for different cadres of health providers. Epidemiological research priorities include prospective studies to evaluate the true prevalence and spectrum of HIV-related renal disease and their progression. Simple diagnostics tools should be evaluated, including urinary dipsticks and point-of-care urea and creatinine tests to screen for kidney injury in primary care settings. Study of urological manifestations of HIV can help determine the extent of disease and outcomes. As patients live longer on ART, the burden of renal and genitourological complications of HIV and of ART can be expected to increase with a commensurate urgency in both discovery and evidence-based improvements in clinical management.

Strengthening faculty recruitment for health professions training in basic sciences in Zambia.

Zambia is facing a crisis in its human resources for health, with deficits in the number and skill mix of health workers. The University of Zambia School of Medicine (UNZA SOM) was the only medical school in the country for decades, but recently it was joined by three new medical schools--two private and one public. In addition to expanding medical education, the government has also approved several allied health programs, including pharmacy, physiotherapy, biomedical sciences, and environmental health. This expansion has been constrained by insufficient numbers of faculty. Through a grant from the Medical Education Partnership Initiative (MEPI), UNZA SOM has been investing in ways to address faculty recruitment, training, and retention. The MEPI-funded strategy involves directly sponsoring a cohort of faculty at UNZA SOM during the five-year grant, as well as establishing more than a dozen new master's programs, with the goal that all sponsored faculty are locally trained and retained. Because the issue of limited basic science faculty plagues medical schools throughout Sub-Saharan Africa, this strategy of using seed funding to build sustainable local capacity to recruit, train, and retain faculty could be a model for the region.
