“…The present study shows that more males were seen with urolithiasis than females. This finding is in agreement with other studies done in Enugu, Nigeria; Kelantan, Malaysia and South India where a male to female ratio of 3.3:1 [1], 1.35:1 [18] and 1.8:1 [8] was found. The higher prevalence in males may be due to their higher level of androgens which have been reported to promote stone formation, while estrogens in females suppress stone formation [19].…”

Background Uroliths are stones formed in the urinary tract. Analysis of stones helps to identify risk factors for their development and prevention of recurrence. Standard stone analysis using modern technology is not routinely done in Nigeria. This study sought to determine the chemical composition of urinary stones seen in Abuja, Nigeria. Methods This was a retrospective study on composition of uroliths. Urinary stones surgically removed from 155 patients through minimal access surgical procedures between January 2015 and August 2019 were analysed. Optical crystallography and infrared spectroscopy were used to determine the chemical composition of the urinary stones. Results A total of 155 urinary stones were assembled from the patients. More stones were removed from male patients and the male to female ratio was 1.9:1. Stones were rare in the extremes of age. The predominant location (89.7%) of stones was in the upper urinary tract. All stones were of mixed composition with calcium oxalate accounting for 93.55%. Calcium oxalate, calcium phosphate and uric acid stones were more common in the upper tract, while 2 of the 3 struvite stones were found in the lower tract. Conclusion Stones found in this study were of mixed composition with the most common constituent being Calcium oxalate and the least common, struvite.

“…In the United States of America, the prevalence of kidney stones for the adult population reportedly increased by 8.8% from 2007 to 2010 [6]. The prevalence of the condition is higher among men than women both in Nigeria (1,2) and other parts of the world [7,8]. It is more common between the 3rd and 6th decades of life [9].…”
