Incidence of urinary calculi and its composition have been showing a remarkable global variation with profound changes in living standards and dietary habits. Indian urinary stone composition is usually different from that of the western countries. Urinary calculi in northern India were composed of pure calcium oxalate monohydrate (COM) and pure calcium oxalate dihydrate (COD) and in Bihar were...

Introduction: Urolithiasis is rare in developed countries. Staghorn calculi are a type of upper urinary tract stone that involves the renal pelvis and extends into at least two calyces. Although all types of urinary stones can potentially form staghorn calculi, approximately 75% are composed of a struvite matrix and are generally associated with urinary tract infection caused by urea -splitting...

The authors report a case of swine urolithiasis caused by improper administration of sulfamonomethoxine and which was diagnosed by examination of urinary sediments and analyzing the composition of the uroliths. The chemical composition of urinary calculi obtained from affected pigs with urolithiasis was further confimed as sulfamonomethoxine by fourier transform infrared (FTIR). It is suggested...

AIM To determine the (i) sensitivity and specificity of ultrasound (USG) in the detection of urinary tract calculi, (ii) size of renal calculi detected on USG, and (iii) size of renal calculi not seen on USG but detected on computed tomography urogram (CTU). METHODS A total of 201 patients' USG and CTU were compared retrospectively for the presence of calculi. Sensitivity, specificity, accura...

Background: Urinary calculi have serious implications in urology. Lower ureteral stones can cause obstructive uropathy and subsequent deterioration of renal function. Because the patient’s symptoms stone size do not predict loss function because there is no clear time threshold for irreversible damage, treatment should be strongly considered any patient with stones. In this study we are compari...

Increased urinary calcium (Ca++) excretion and the presence of negative Ca++ balance is well documented in primary hyperaldosteronism. However, renal calculi as a major manifestation of this disorder is not previously described. This report describes probably the first patient who presented with renal calculi in association with primary hyperaldosteronism. We believe that primary hyperaldostero...
