Open Ureteric Exploration in Aminu Kano Teaching Hospital: Indications and Outcome.

Background: Open ureteric exploration is an important procedure in urology employed in the management of ureteric obstruction from various causes. Ureteric obstruction is a common urological problem leading to significant morbidity and may lead to obstructive nephropathy in patient with bilateral obstruction or obstruction in a solitary kidney. Objective: The study aims to determine the demographics of patients who underwent open ureteric exploration, indications, and complications associated with open ureteric exploration. Materials and Methods: This is a retrospective review of all patients who had open ureteric exploration between January 2012 and September 2015. A total of 41 patients had the procedure within this period. Their case notes were retrieved; relevant information was collected with a structured proforma and analyzed with SPSS version 17. Result: In the 41 patients reviewed, the age range was 3 to 70 years with mean age of 33.1 ± 12.14. The commonest age group was 21 - 30years accounting for about 32% (n = 13). Male patients account for 68% (n = 28) while females 32% (n = 13). The indications were ureteric stone 58%, ureteric stricture 23% and external compression 19%. The commonest site of obstruction was the distal ureter 84% (n = 36). Ureterolithotomy was the predominant definitive procedure performed in 58% (n = 24). About 24% (n = 9) of patients developed complications, which includes urinary tract infections (UTI), post-operative intestinal obstruction and surgical site infections. Conclusion: The distal ureter was the commonest site of obstruction while the commonest procedure was ureterolithotomy. Open ureteric exploration is still an important option in the management of ureteric obstruction especially in resource constrain areas.

Donor Nephrectomy Through Mini-Flank Incision: A Single-Centre Experience Among Nigerian Patients.

Background and objective The field of kidney transplantation in sub-Saharan Africa is still in the rudimentary stages. The majority of patients with chronic kidney disease have no access to renal replacement therapy, leading to very high mortality rates. Donor nephrectomy (DN) is an important aspect of kidney transplantation. Over the last two decades, open DN (ODN) has given way to minimally invasive techniques like laparoscopic DN (LDN) and robotic-assisted DN. In this study, we aimed to describe our experience with mini-flank incision donor nephrectomy (MIDN) at a Nigerian renal transplant center. Materials and methods We conducted a retrospective review of all DN cases performed at a single Nigerian kidney transplantation center over a three-year period. Information obtained from these patients was classified into pre-, intra-, and postoperative. The data included sociodemographic characteristics, preoperative preparation, details of intraoperative techniques, and postoperative findings. These were entered into a proforma and analyzed using SPSS Statistics version 21 (IBM Corp., Armonk, NY). Results A total of 230 patients underwent ODN during the study period. The majority of the donors were males (92.8%) with a mean age of 30.83 ±8.43 years. The body mass index (BMI) of most (76.1%) of the donors was within the normal range (18.5-24.9 kg/m2). The duration of DNs ranged from 72 to 154 minutes with a mean duration of 130 ±28 minutes. The length of flank incisions ranged from 7.8 to 12 cm with a mean incision length of 10.8 ±1.0 cm. Donors who had MIDN attained satisfactory postoperative pain control with about 90% of them having a BMI of <30 kg/m2. Oral intake and ambulation were commenced on the first postoperative day, and the cosmetic outcomes were deemed acceptable in over 90% of kidney donors. Conclusion Mini-incision for DN through the flank approach is a suitable alternative to LDN in the developing world where facilities and skills for LDN or robotic nephrectomies are largely unavailable. It offers a short recovery time, early ambulation, and excellent allograft outcomes.

Scoping review: bladder cancer in Nigeria - what are the gaps in clinical care and research?

OBJECTIVES: There are currently no national guidelines regarding bladder cancer treatment and clinical care pathways in Nigeria. The aim of this scoping review was to identify any gaps in the knowledge of epidemiology, clinical care and translational research in order to aid the development of a defined clinical care pathway and guide future research. METHODS: A scoping review was conducted by searching Medline, Ovid Gateway, The Cochrane library and Open Grey literature using predefined search terms from date of inception to June 2020. Studies were included if they discussed the epidemiology or treatment pathway of bladder cancer. All data were charted and were analysed in a descriptive manner. A consultation phase was also conducted consisting of a multidisciplinary team of clinicians and bladder cancer survivors. RESULTS: A total of 19 studies were deemed suitable for inclusion. The themes included the epidemiology of bladder cancer (high prevalence of schistosomiasis), research surrounding the biology of the disease and translational research including potential biomarkers. The consultation phase highlighted some possible sociocultural and infrastructural issues relating to both the diagnosis and treatment of bladder cancer, with poor knowledge of bladder cancer and its symptoms within the general population identified as a key issue. CONCLUSION: Even though the factors surrounding the relationship between schistosomiasis and the histopathology of bladder cancer remain unclear, there is potential for screening for schistosomiasis in endemic regions of sub-Saharan Africa. Other key areas for future research include the dissemination of information to the general population surrounding bladder cancer and its symptoms to encourage prompt diagnosis.

Scoping review protocol: bladder cancer in Nigeria: what are the gaps in clinical care and research?

INTRODUCTION: Bladder cancer (BC) is the 10th common cancer worldwide and ranks seventh in Nigeria. This scoping review aims to identify the gaps in clinical care and research of BC in Nigeria as part of the development of a larger national research programme aiming to improve outcomes and care of BC. METHODS AND ANALYSIS: This review will be conducted according to Arksey and O'Malley scoping review methodology framework. The following electronic databases will be searched: Medline (using the PubMed interface), Ovid Gateway (Embase and Ovid), Cochrane library and Open Grey literature. Two independent reviewers will screen titles and abstracts and subsequently screen full-text studies for inclusion, any lack of consensus will be discussed with a third reviewer. Any study providing insight into the epidemiology or treatment pathway of BC (RCTs, observations, case series, policy paper) will be included. A data chart will be used to extract relevant data from the included studies. Results will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. A consultation process will be carried out with a multidisciplinary team of Nigerian healthcare professionals, patients and scientists. ETHICS AND DISSEMINATION: The results will be disseminated through peer-reviewed publications. By highlighting the key gaps in the literature, this review can provide direction for future research and clinical guidelines in Nigeria (and other low-income and middle-income countries), where BC is more prevalent due to local risk factors and healthcare settings.

Outcome and complications of permanent hemodialysis vascular access in Nigerians: a single centre experience.

BACKGROUND: It is widely accepted that autogenous arteriovenous fistula (AVF) carries less morbidity and mortality compared to all other forms of vascular accesses in maintenance hemodialysis patients. There is paucity of data on vascular access from sub-Saharan Africa. The aim of this study was to assess the outcome and complications of permanent vascular access in our center. MATERIALS AND METHODS: The study is a prospective, hospital-based, longitudinal study. All consecutive patients on maintenance hemodialysis in Aminu Kano Teaching Hospital who were referred to the surgical unit of for creation of permanent hemodialysis vascular access were included in the study. The patient's clinical and demographic data were documented. Data about vascular access types, outcomes, and complications were obtained over a 1-year period from the time of vascular access creation. RESULTS: One hundred and seventy four patients were operated upon between January 2008 and December 2010 with a mean age of 46.4 years (range 18-76 years) and a male to female ratio of 1.5:1. Brescio--Cimino fistula was performed in 110 (63.2%) patients, brachiocephalic (Kauffmann) fistula in 51(29.3%), and synthetic graft in 1 (0.6%) patients respectively. Ten patients (5.7%) had brachio-brachial transposition arteriovenous fistula and 2 patients (1.1%) had transposition graft using harvested long saphenous vein. One-year patency rate was 63.2%. Complications encountered include AVF failure in 47(27.3%), steal syndrome in 2(1.1%), distal venous insufficiency in 2(1.1%), and false aneurysm in 6(3.5%) patients. CONCLUSION: The outcome of permanent vascular access is favorable in our patient population with a one-year patency rate of 63.2%. The first choice of vascular access in our maintenance dialysis population should be AVF.

Organ transplantation: legal, ethical and islamic perspective in Nigeria.

Organ transplantation dates back to the ancient times and since then it has become one of the important developments in modern medicine; saving the lives, as well as improving the quality of life of many patients. As the demand for organ transplantation far exceeds the organ availability, the transplant program is often saddled with complex legal and ethical issues. This review article highlights the legal and ethical issues that might arise regarding organ transplantation and appraises the existing legal frame work governing organ transplantation in Nigeria. Information on legal, cultural, religious and medical ethical issues regarding organ transplantation in Nigeria was obtained by searching the PubMed and Google Scholar, conference proceedings, seminar paper presentations, law library and other related publications were collated and analyzed. In decision making for organ transplantation, the bioethical principles like autonomy, beneficence and justice must be employed. It was believed by Catholic theologians that to mutilate one living person to benefit another violates the principle of Totality. Among Muslim scholars and researchers, there are those who throw legal support as to its permissibility while the other group sees it as illegal. Organ/tissues transplantation is considered a medical intervention that touches on the fundamental rights of the donor or the recipient. Where there is an unlawful infringement of the right of such persons in any way may be regarded as against Section 34 of the 1999 Nigerian Constitution dealing with right to dignity of the human person. Worldwide, the researchers and government bodies have agreed on informed consent for organ/tissue donation and for recipient should be obtained without coercion before embarking on such medical treatment Worldwide organ transplantation has become the best medical treatment for patients with end stage organ failure. However, there is no law/legislation backing organ/tissues transplantation in Nigeria. The government should take measures to combat transplantation tourism and the problem of national and international trafficking in human tissues and organs, ethics commission and National Transplant registry should be established in order to monitor and regulate the programme in the country.
