SONOGRAPHIC EVALUATION OF NORMAL RENAL VARIANTS IN POPULATION OF LAHORE
Abstract
BACKGROUND AND OBJECTIVES: Congenital renal diseases consist of a variety of entities. The age of presentation and
clinical examination narrow down the differential diagnosis; however, imaging is essential for accurate diagnosis
and pretreatment planning. Ultrasound is often used for initial evaluation. To evaluate the normal renal variants
on ultrasound in population of Lahore.
METHODOLOGY: A cross sectional analytical study was conduct at university ultrasound clinic township
University of Lahore. Total sample size was 258. SPSS version 21.0 was used for data analysis.
RESULTS: Out of total number of 258 patients, 98 (38 %) were females and 160 (62%) were males, normal variants
of kidneys in which 45 (17.4 %) patients had Lobulation variant, 114 (44.1%) had column of bertin, 55
(21.3%) had dromedary hump, 23 (8.9%) had duplex collecting system and 21(8.1%) had junctional parenchymal
defect. Cross tabulation shows between gender and variant, column of bertin is most frequent variant in both
genders.
CONCLUSION: Study concluded that normal variants are commonly encountered on ultrasound imaging. In this
study the most common normal renal varient was colomn of bertine and least common was junctional parenchymal
defect. Sonography continues to occupy a central role in the evaluation and detection of different congenital
normal anatomical variants due to its advantage of rapid scanning time, lack of radiation exposure, cost effective
and easy feasibility
