title: Normal urographic findings in Nigerians.
abstract: A review of excretory urographic studies in Nigerians at the Lagos University Teaching Hospital shows that the average renal lengths in adult patients is 12.2 cm. Male patients had slightly longer kidneys than females while the left kidney was longer and higher than the right in most cases and in both sexes. There was symmetry in the pelvicaliceal architecture of both kidneys of the same patient in 85% of cases while disparity in renal length for the same patient was less than 1.5 cm in 89% of cases. Pelviureteric duplication was seen in 4.4% of patients with a male to female ratio of 2:1. The results obtained for the Nigerian patients are not significantly different from those obtained by other authors on caucasians.
