Introduction: Infertility is the inability to achieve pregnancy after 12 months of regular, unprotected sexual intercourse by a couple of childbearing age. It is a real public health problem because of its high prevalence in both developed and developing countries. Female infertility occupies a prominent place in reproductive health in Africa such as in our country Mali. The objective of this work was to determine the hysterosalpingography profile of utero-tubal lesions in the etiological research of female infertility in Mopti. Materials and Method: This was a cross-sectional descriptive study covering a period of one year from January 2019 to December 2019 in the radiology department of Sominé Dolo Hospital in Mopti. The variables analyzed were patient age and hysterosalpingography results. The hysterosalpingography examination was performed 3 or 4 days after menstruation on a remote-controlled table under fluoroscopic control. Data analysis was done with the aid of SPSS version 22 and Excel 2016 software. Results: During the study period, 9012 patients were seen in the imaging department, including 115 patients, or 1.3% for infertility assessment. The 25 - 29 age group was the most represented with 34 patients or 29.6%. The mean was 30.39 ± 6.96 years with extremes of 17 and 46 years. Tubal abnormalities represented 45 cases or 39.1%. Hydrosalpinx was the most prevalent with 26 cases or 36.6%. Conclusion: Tubal lesions were the most observed, especially hydrosalpinx following. Hysterosalpingography remains the first choice in the radiological assessment of female infertility in our context.

Sirenomelia is a rare fetal malformation with more or less complete fusion of both lower limbs consistently associated with bilateral renal abnormalities. The positive diagnosis can be made antenatally by ultrasound during the first trimester of pregnancy but often before the 22 weeks of amenorrhea. The objective was to think about the possible diagnosis by ultrasound in front of the urinary anomalies and the ologiamnios during the morphological study of the second trimester of pregnancy. We report a case of sirenomelia in a 25-year-old lady as part of the routine prenatal assessment suspected and confirmed during the morphological ultrasound of the second trimester of pregnancy and confirmed after the termination of pregnancy in Mali in the Health Center of Reference of commune III of the district of Bamako. The morphological ultrasound made it possible to diagnose the malformation of the urinary tract, the amniotic fluid and to make the therapeutic decision of medical termination of pregnancy at the end of confirming the siren syndrome.

Introduction: Pathologies of the lower urinary tract are common in urology composed of various conditions, responsible for urinary disorders. Despite the new methods, exploration in Africa is mainly based on retrograde urethrocystography (UCR). The main objective was to determine the importance of UCR in the diagnosis of pathologies of the lower urinary tract. Materials and Methods: This was a retrospective and descriptive study covering a period of 5 years (July 2016-June 2021). It involved all patients admitted to the ward for retrograde urethrocystography during the period. A remote-controlled table of the GE PRESTILIX 1600× type was used for the examinations. Results: At the end of our study we collected 100 cases of pathologies of the lower urinary tract out of a total of 112 RCUs performed or 89.28%. Pathologies of the lower urinary tract accounted for 78% of the UCRs in the department. The age group of (61 - 70) was the most affected with extremes from 1 year to 101 years. Non-specific urination disorders were the most common indications (43%), followed by acute urine retention (18%). Acquired urethral pathology was the most common (89%), followed by bladder neck disease 5% and posterior urethral valve with 4%, Bladder struggle was the most common associated sign (54%) with post-urination residue in 97% of patients. Conclusion: Pathologies of the lower urinary tract are relatively common in our region, dominated by urethral narrowings. Retrograde urethrocystography remains the reference examination in our control for the diagnosis of obstructive pathologies of the lower urinary tract while specifying the seat of the obstacle.

Objective: To describe the CT findings and clinico-epidemiological aspects of coronavirus pulmonary lesions at the Radiology Department of Mother-Child Luxembourg’s Hospital in Bamako, West Africa. Materials and Method: This was a cross-sectional descriptive study over a period of three months (November 2020-January 2021). The study involved all patients with a clinical suspicion of COVID-19 or confirmed cases with suggestive CT scan lesions during this period. No patients without suggestive CT lesions were not included. The variables were age, sex, clinical data, lungs lesions on CT scan and their severity. Results: Out of 202 patients enlisted, the age group 52 - 63 years was more frequent (30.2%), i.e. an average age of 60.43 years (range 23 and 95 years). Men represented 56.4% or a sex ratio of 1.3. Cough was the most common clinical manifestations (26.7%). Major findings were mixed appearance of the lung lesions (45.5%). The peripheral distribution was 57.4% and the bilateral topography was 98%. These lesions were extensive in the majority of our patients with 28.2%. Conclusion: Older people dominated the socio-demographic profile of our series with a predominance of men. Cough was the most observed clinical information. Mixed lesions with peripheral and bilateral distribution dominated the semiological tomodensitometric aspects. By severity, extensive lung lesions were the most commonly observed.

Aims: To determine the impact of varicocele on the result of the spermogram in a group of hypo-fertile or infertile men. Patients and Method: This was a cross-sectional, descriptive study concerning 264 men collected between February 2020 and March 2022 at the Fertilia medical clinic in Bamako. The study population consisted of consenting male subjects presenting for infertility. All of our patients had already done a spermogram, they then benefited from a scrotal Doppler ultrasound. The scrotal echo-doppler was completed by an abdominal and pelvic echography in search of a possible etiology, in particular a renal cancer, a thrombosis of the renal or spermatic vein, a retroperitoneal mass or a nutcraker syndrome. Testicular volume was measured on ultrasound according to Lambert’s formula (length × width × height × 0.71). A volume = 16 ml was considered normal. Results: 264 patients were recruited in ours. The average age was 33 years with extremes ranging from 25 to 65 years. 149 patients or 56.44% were between 30 and 45 years old. 213 patients or 80.68% had primary infertility. All the patients, i.e. 100%, had a sperm anomaly and dilation of the pampiniform plexus veins. The most common sperm abnormalities were oligoasthenoteratozoospermia, which concerned 214 patients, or 81%, followed by azoospermia (40 patients, or 15%) and oligospermia (10 patients, or 4%). 213 patients or 80.68% had a Hirshen grade II varicocele, 45 patients or 17% had grade I and 06 patients or 2.27% had grade III. Among the 6 patients, 04 had left testicular atrophy and 2 bilateral atrophy. The venous reflux was more accentuated on the left than on the right. Conclusion: Varicocele is significantly found in men with infertility. Sperm alterations concern both the concentration of spermatozoa, their mobility and their vitality. Even if the mechanism of alteration of the sperm parameters is not well elucidated, our study made it possible to make the link between the dilation of the veins of th

Background: The endometrium is the tissue that lines the inside of the uterus. It undergoes multiple changes during the menstrual cycle and prepares to welcome the fertilized egg. Endovaginal ultrasound is a first-line examination in the assessment of female infertility. Objective: We aimed to determine the impact of endometrial status by endovaginal ultrasound on the outcome of embryo transfers. Subjects and Methods: This was a prospective cross-sectional study of 150 women collected between January and October 2020 at the “Le Diafounou” medically assisted procreation laboratory. Were included in the study, women presenting for desire of pregnancy and having continued the treatment until the transfer of fresh or frozen embryos. An uterine score was used. This score took into account the thickness of endometrium, it is coffee bean aspect, the presence of the notch, the echogenicity of the endometrium, the pulsatility index, the presence of the flow at the end of diastole and sub-endometrial flow. Ultrasounds were performed using a General Electric logic 500, logic 9 and Voluson E8 device. The data was entered into Excel and then analyzed using SPSS version 21. Results: 150 women were selected for the study. 83 women or 55.3% were between 17 and 35 years old and 44.7% were over 35 years old with an upper limit of 50 years old. The number of women who became pregnant was 69% or 46%. The average thickness of the endometrium was 11.40 mm with extremes of 4.65 mm and 18.6 mm. There was a correlation between the thickness of the endometrium and obtaining a pregnancy (p i.e. 88.7%. The pulsatility index was relatively low for those who started a pregnancy, i.e. 90%. The high pulsatility index is one of the reasons for the failure of embryo implantation. The correlation was significant (p = 0.009). 141 women had no notch in the uterine arteries, i.e. 94%. 94 women or 62.7% had a triple line endometrium or typical coffee bean appearance. End-diastolic flow was observed in 12

Aims: Infertility is a major problem in our current societies and the Fertilia medical clinic in Bamako is a center for medical assistance in procreation (MAP) where there is an increasingly growing demand for ultrasound. The objective of our study was to investigate the ultrasound causes likely to prevent the occurrence of pregnancy in a group of infertile and subfertile women. Subjects and Methods: This was a 5-year cross-sectional and prospective study, between January 2017 and January 2022, which involved 250 women wishing to become pregnant (infertile or subfertile), who came for pelvic ultrasound or follicular monitoring and who agreed to participate in our study. The parameters used were ultrasound reports including uterine, ovarian and tubal pathologies. It should be noted that in some cases no ultrasound cause of infertility was found. Data were entered and analyzed in SPSS. Results: 250 women were recruited into our. The average age was 32 years with extremes ranging from 17 to 51 years. 179 patients or 71.6% were between 17 and 35 years old. 139 patients or 55.6% had secondary infertility against 44.4% primary infertility. 202 patients or 80.8% had at least one ultrasound lesion and 48 patients or 19.2% had no significant ultrasound abnormality. The most represented ultrasound lesions were of uterine origin with 72.20%, 23.7% ovarian lesions and 04% tubal lesions. Uterine lesions were dominated by myomas, adenomyosis, endometrial polyps, uterine malformations and synechiae. As for ovarian lesions we noted cysts, polycystic ovary syndrome (PCOS), ovarian endometriosis, non-follicular ovaries and tubal ultrasound lesions showed unilateral or bilateral hydrosalpinx. Conclusion: In our study, ultrasound was an invaluable contribution to the diagnosis of the causes likely to explain subfertility and infertility in our respondents. She highlighted uterine, ovarian and tubal lesions, some of which could be corrected and pregnancies ensued.

Groundwater resources are the main sources of water used to supply drinking water to the population of the Ouémé Delta via the Continental Terminal aquifer. Urbanization, population growth, and agricultural and industrial activities have resulted in a deterioration in the quality of these resources. To assess the quality of the delta’s groundwater and its suitability for human consumption and irrigation, a total of fourteen (14) physico-chemical parameters were analyzed in some forty existing water points between September 2020 and March 2021, using standard water analysis techniques. The values obtained were compared with the potability standards recommended by the World Health Organization (WHO) and the Republic of Benin and were subjected to statistical analysis (principal component analysis (PCA)). In addition, methods for determining the suitability of water for irrigation were used. The results showed that the waters are acidic to slightly neutral and influenced by ambient temperature. In addition, the waters are moderately mineralized, with conductivities (24 - 1205 μS/cm) in line with WHO standards. A comparison of the analytical results of the WHO (2017) and Benin (2001) standards indicates that the majority of the waters studied are of good quality for all the chemical parameters considered. Nevertheless, some samples show levels of nitrates (21%), potassium (14% to 16%), calcium (13%), ammonium (12%), nitrites (8%) and bicarbonates (10%) over their respective standards. The Wilcox and Riverside diagrams indicate that the majority of waters (90%) have excellent suitability for irrigation and no negative effect on soil fertilization.

Accessing drinking water is a global issue. This study aims to contribute to the assessment of groundwater quality in the municipality of Za-Kpota (southern Benin) using remote sensing and Machine Learning. The methodological approach used consisted in linking groundwater physico-chemical parameter data collected in the field and in the laboratory using AFNOR 1994 standardized methods to satellite data (Landsat) in order to sketch out a groundwater quality prediction model. The data was processed using QGis (Semi-Automatic Plugin: SCP) and Python (Jupyter Netebook: Prediction) softwares. The results of water analysis from the sampled wells and boreholes indicated that most of the water is acidic (pH varying between 5.59 and 7.83). The water was moderately mineralized, with conductivity values of less than 1500 μs/cm overall (59 µS/cm to 1344 µS/cm), with high concentrations of nitrates and phosphates in places. The dynamics of groundwater quality in the municipality of Za-Kpota between 2008 and 2022 are also marked by a regression in land use units (a regression in vegetation and marshland formation in favor of built-up areas, bare soil, crops and fallow land) revealed by the diachronic analysis of satellite images from 2008, 2013, 2018 and 2022. Surveys of local residents revealed the use of herbicides and pesticides in agricultural fields, which are the main drivers contributing to the groundwater quality deterioration observed in the study area. Field surveys revealed the use of herbicides and pesticides in agricultural fields, which are factors contributing to the deterioration in groundwater quality observed in the study area. The results of the groundwater quality prediction models (ANN, RF and LR) developed led to the conclusion that the model based on Artificial Neural Networks (ANN: R2 = 0.97 and RMSE = 0) is the best for groundwater quality changes modelling in the Za-Kpota municipality.
