title: Pattern of urolithiasis in Benin City, Nigeria.
abstract: A retrospective study was performed to determine the frequency and pattern of urinary stone disease in a black African population. Urolithiasis was found to be a rare condition in the black African occurring with a frequency of 6.3 per 100,000 hospital population, with a male:female ratio of 4:1. Urinary stasis and infection are associated or etiologically related factors in a significant number of patients. Idiopathic stone disease is uncommon (28% of patients). A recurrence rate of 10% is similar to that found in other areas of the world where the disease is more prevalent.
