Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 2
Abstract
Background: Urolithiasis is stone formation in the urinary tract which can be removed surgically to relieve symptoms or passed spontaneously in urine. They are sent to the laboratory for analyses, because knowledge of the chemical composition of stones aids appropriate treatment in order to prevent reoccurrence. We therefore aimed to determine the chemical composition of urinary calculi in our patients. Method: This was a retrospective study of the chemical composition of urinary calculi submitted to the Chemical Pathology laboratory at University of Nigeria Teaching Hospital, Enugu over a four year period. After conducting physical examination of the calculi received in the laboratory, a portion was crushed and analyzed using flame and chemical reagents. Results: Forty-fivestones were obtained from 37(82%) males and 8 (18%) females of which 37(82%) were adults and 8 (18%) children. Calculi were obtained from the following anatomic sites: Kidney 9(20%), Ureter 2(4.4%), Bladder 22 (48.9%), and Urethra 12 (26.7%). The stones were all mixed stones with chemical composition of: calcium 38, oxalate 8, magnesium 44, ammonium 44, phosphate 44, carbonate 1. Conclusion: Urinary stones were more prevalent among males and commonly found in the urinary bladder. The stones were mixed of which struvite (ammonium, magnesium, phosphate) was the most prevalent chemical found in the calculi which may suggest urinary tract infections as the causative factor.
