Journal of Communicable Diseases. 2000 Sep; 32(3): 216-21http://imsear.searo.who.int/handle/123456789/111589Biochemical and bacteriological study of urine, nidus and chemical analysis of 100 calculi from 100 patients admitted in the Regional Institute of Medical Sciences, Imphal from November, 1997 to October 1999 were done. About 47% of the cases had positive urine culture and nidus culture. Escherichia coli was the commonest bacteria isolated both in the urine and nidus of calculi. The commonest radical present in the calculi was calcium while the rarest was uric acid. The stones were composed mainly of calcium oxalate and/or phosphate followed by struvite, then mixed stone.engCalcium Oxalate --analysisCalcium Phosphates --analysisEscherichia coli --isolation & purificationHumansUrinary Calculi --microbiologyUrinary Tract Infections --complicationsComparative Study
