title: Urolithiasis in Sudan. Geographical distribution and the influence of climate.
abstract: Urolithiasis is common throughout the Sudan with the exception of the southern region where it is rare. The latter region is cooler and decidedly more moist than the other provinces during the hot months of the year (May-October). In the northern provinces urolithiasis is commoner in areas with lower relative humidity.
