[Epidemiology of a cohort of 450 urolithiasis at the Yalgado Ouédraogo university hospital of Ouagadougou (Burkina Faso)].
OBJECTIVE
To report the epidemiological and diagnosis characteristics of urolithiasis in the city of Ouagadougou (Burkina Faso).


METHODS
We performed a retrospective and descriptive study of a cohort of urolithiasis patients from January 2009 to December 2011 at the department of urology of the Yalgado Ouédraogo University hospital of Ouagadougou. The minimum required data were: age, gender, occupation, residence, complete medical observation and medical imaging results.


RESULTS
Four hundred and fifty patients with a median age of 35 years were included in this study. Urinary stones prevalence was 12.5%. There was a male predominance with a sex ratio of 1.91. Renal colic found in 32% of patients was the main pattern of consultation. Urinary schistosomiasis was the main etiological factor correlated with the occurrence of urolithiasis (P < 0.05). The majority of urinary stones in this study were located in the upper urinary tract (86.5%). Complications were dominated by urinary tract infections (45.2%) and obstructive renal failure (8.9%).


CONCLUSIONS
The characteristics of urolithiasis in our center were similar to those reported in the developing world but seem to evolve toward those of industrialized countries.
