Background:Urolithiasis may result in many complications including renal failure. There is a paucity of documented scientific study on the prevalence of urolithiasis in the University of Abuja Teaching Hospital within the Federal Capital Territory, Nigeria. The aim of the study was to assess the prevalence of urolithiasis in patients undergoing ultrasound at University of Abuja Teaching Hospital.Materials and Methods:This study which adopted a survey approach was conducted at the Department of Radiology, University of Abuja Teaching Hospital between June 2014 and May 2015. A total of 2310 patients that underwent abdominopelvic ultrasound in the department who aged between 2 and 64 years and met the inclusion criteria participated in the study. They were recruited using a convenience (nonprobability) sampling technique. Data obtained were subjected to descriptive statistics and analyzed using Student's t-test. P < 0.05 was considered statistically significant.Results:A total of 2310 patients were scanned, 31 patients were sonographically identified with urolithiasis. The prevalence of urolithiasis was 13.4/1000. The mean age was 31.12 ± 3.69 years. There were 58.06% males and 41.93% females giving a male-to-female ratio of 1.3:1. The peak age of incidence was 21–50 years. Majority (22 [71%]) were located in the upper urinary tract, whereas 9 (27%) were in the lower urinary tract. The most common presenting symptoms were flank/loin pains (renal colic) noted in 12 (40%) patients, followed by hematuria in 4 (13.3%) patients.Conclusion:The prevalence of urolithiasis was 13.4/1000. This information can be utilized in formulating future health plans for prevention of urolithiasis in the hospitals within this locality.

Background: Coronavirus disease (COVID-19) is a pandemic that is ravaging the world. Chest imaging plays an important role in the diagnosis and management of patients with COVID-19-related chest infections. This study determined the pattern of chest radiographic features among confirmed COVID-19 patients in Abuja, Nigeria. Materials and Methods: Chest radiographs (CXR) of COVID-19 patients were reviewed, and the radiological features of the lesions were recorded based on the type of opacities, pattern of distribution in the lung fields, side of lesions, and severity of pulmonary abnormalities. Results: The radiographs of 77 patients were analyzed. Their age range was 15–88 years with a mean of 47.4 years and peak age group of 51–60 years. Gender distribution of the patients was 58 (75.3%) males and 19 (24.7%) females giving a male-to-female ratio of 3.1: 1. Fifty-five (71.4%) of the patients had normal CXRs, whereas 22 (28.6%) patients had abnormal pulmonary appearances. Seven (58.3%) out of 12 patients with mild interstitial pneumonia had unilateral disease, whereas 5 (41.7%) had bilateral disease. Combined total of ten patients with moderate and severe interstitial pneumonia all had bilateral disease. Conclusion: Plain CXR gives reliable diagnosis about the presence and degree of interstitial pneumonia in COVID-19 patients. CXR should be routinely done as a baseline diagnostic tool in patients positive for reverse-transcription polymerase chain reaction test. The findings in the CXRs of COVID-19 patients in sub-Saharan Africa are similar to those reported from the other parts of the world.
