The variations in urinary calculi are based on different diameters, which range in the form of sand grain to a urinary collecting system so that it can pass through the urinary tract regardless of any symptoms. To determine the composition of urinary calculi for patients in Northern Jordan by using Fourier Transform Infrared Spectroscopy method, samples of urinary calculi were retrieved from patients at King Abdullah University Hospital and Princess Basma Teaching Hospital. Urinary calculi were surgically removed from patients either arthroscopically (n = 35), or by percutaneous nephrolithotomy (PCNL) (n = 15) over a period of 16 months (2013-2014) and were brought to the laboratory in sterile containers. They were analyzed by Fourier Transform Infrared Spectroscopy method. A total of 39 male patients (78%) aging 23-85 years and 11 female patients (22%) aging 33-69 years were included in the study. The calculi comprised of 40% calcium oxalate and uric acid, 24% calcium oxalate, 18% pure uric acid, 12% magnesium ammonium phosphate, and 6% calcium oxalate and calcium phosphate. Mixed urinary calculi of calcium oxalate and uric acid were predominantly found among the patients with the following characteristic IR bands [1637cm-1 C=C Stretching, 1021 cm-1 N-H stretching, 780 cm-1 aromatic C-N stretching].
