Twenty four hour urinary aberrations in renal stone formers

Aim: to compare the urinary aberrations in renal stone formers with healthy controls . methods: it is case control study carried out at department of urology,nishtar hospital multan from may 2016 to november 2016. patients with renal stones n-160 were recruited into group-a and equal number n-160,age matched healthy male volunteers with no evidence of urolithiasis were recruited in group-b . urine volume). findings of aberrations were noted. results: mean age (±s.e.m.) of patients was 41.68±0.70 vs. 39.65±0.76 years in group-a and group-b respectively. in our study low urine volume was evident in 21(13.1%) cases and 10(6.3%) controls in group-a and b respectively. hypercalciuria was found in 42(26.3%) cases and 23(14.4%) controls in group-a and b respectively. hyperuricosuria was found in 21(13.1%) cases and 19(11.9%) controls in group-a and b respectively. low urine volume and hypercalciuria were significantly more common in group-a compared with group b while hyperuricosuria had no significant difference between group-a and b. conclusion: present study concludes that hypercalciuria was more frequent in cases (26.3%) than controls (14.4%) and hyperuricosuria was 13.1% in cases and 11.9% controls. low urine volume was evident in 13.1% cases and 6.3% controls.
