In order to obtain patients history different hospitals including Nishtar hospital Multan, Life kidney stone center, Siyal medical center and Medicare hospital were visited. Of the 263 cases of urinary stones, 193(73.38%)were in kidney, 57(21.67%) were in the urinary bladder, 13(4.94%) were in ureter. The three predominant symptoms associated with urinary stones were lumber pain, 88(33.46%), burning in micturition 72(27.37%) and heamaturia 103(39.16%).Other related symptoms were vomating 75(28.51%), fever 50(19.01%), dribbling 25(9.50%), pysuria 34(12.92%), dysuria 30(11.40%) and retention 49(18.63%).According to the chemical composition of the urinary stones, most of the stones examined in this study were of calcium oxalate + uric acid 66(25.09%), calcium oxalate 57(21.67%), calcium oxalate + calcium phosphate 51(19.39%), pure uric acid 44(16.73%), calcium oxalate + calcium phosphate + uric acid 29 (11.02%), pure calcium phosphate, 3(1.14%) and others 13 (4.94%) were of mixed lithiasis. Of these cases the incidence of formation of calcium oxalate + uric acid stone, was maximum in males of age group 14 B 49 years.]]>Ahmed, M.,1983Ahsan, I.,1997Asplin, J.R., M.J. Favus and F.L.
