Urolithiasis is an ancient disease with global distribution. It refers to stones originating anywhere in the urinary system. Urinary calculi or stones are the most common cause of acute urinary system obstruction. The study was aimed with finding out the common site of urinary calculus in kidney ureter bladder (KUB) region. This was a prospective cross-sectional study conducted from June 2012 t...

Bladder stones comprise 5% of urinary tract stones. Generally, they occur in the presence of bladder neck obstruction, urinary tract infections associated with neurogenic bladder and foreign objects. They are more common among men than women. Infection stones comprise approximately 15% of urinary tract stones. A giant bladder stone is a rare finding in contemporary urological practice. The gene...

Epidemiology and pathogenesis in urinary stones diagnosed in 184 patients were studied. Mean age was 38.3 years. Male to female ratio was 2.5:1. Stones were predominantly of mixed type: calcium oxalate was the commonest compound. Anatomical distribution of urinary stones was 67.4% renal, 12.5% ureteric and 14.6% bladder. Recurrence rate following previous surgical removal was 15.0%. Bacteria we...

Introduction: Micro-CT scanner with a resolution of about 5 micrometers is one of the modalities used to create three-dimensional/two-dimensional images of urinary stones. This study aimed to optimize imaging parameters in micro-computed tomography (CT) scanner based on the signal-to-noise ratio (SNR) of urinary stones for the analysis of stone composition. <stro...

PURPOSE This retrospective study evaluated the unenhanced multi-detector computed tomography (MDCT) findings of urinary system calculi and the secondary signs associated with ureteral stones in children. MATERIALS AND METHODS The study included 87 children (54 boys, 32 girls) with a mean age of 89 months (range: 5 months to 16 years) who were referred to us from various departments and were e...

Uric acid stones are the most readily dissolvable of all types of urinary stones. By maintaining urinary pH between 6.2-6.8 with the use of sodium acid citrate or uralyt-U and reducing serum uric acid by allopurinol, we tried to dissolve 107 stones in 67 patients. Ninety three (86.9%) stones were dissolved and 6 (5.6%) passed spontaneously within a period of one year. Eight (7.5%) stones were r...

Of 50 patients with urinary calculi, upper tract stones were common between 15-44 and lower tract stones between 0-14 and above 44 years of age. Urinary calculi contained calcium, phosphate, oxalate, urate/uric acid, ammonium, magnesium and carbonate. The frequency of occurrence of each of these radicals in sixty stones was 93.33, 83.33, 61.67, 51.67, 25.00 and 13.33% respectively. Five (27.78%...
