[Etiological orientation from the analysis morphological and constitutional of urinary stones in Conakry].
BACKGROUND
The epidemiological profile of urinary stones varies from region of the world to another according to food habit and certain enviromental factors. The aim of our study was to establish an etiological approach of the urinary lithiasis collected in Conakry by morphological and constitutional analysis.


METHODS
It was a prospective study from january 1 rst 2003 to january 1 rst 2004 concerning all the stones collected. They were analysed by binocular magnifying glass and infra red spectrophotometry of Fourier.


RESULTS
During the period, 18 patients were observed (14 male, 4 femele) of 27.4 +/- 4 years old (from 2 to 69) living mainly in urban environment. From these patients 28 stones were collected; 12 spontaneously and 16 surgicaly. Their composition were whewellite (36%), struvite (29%), carbapatite (14%), urates (14%) and weddellite (7%). In Conakry stones come mainly from hyperoxaluria and urinary tract infection; hypercalciuria is uncomon.


CONCLUSIONS
The urinary calculations examined among patients show in the adult a prevalence of elements in favour of a hyperoxalurie and a notable context of urinary infections in particular in the child; the pure hypercalciurie remains negligible in Conakry, we plan to lead a thorough work to the national scales.
