Ultrasonography is the reference imaging modality for evaluating renal failure, whether acute or chronic, due to its simplicity, safety, and low cost. Chronic kidney disease (CKD), often silent and diagnosed at a late stage, leads to a progressive and irreversible reduction in renal size and function, with a prevalence that increases with age. In Guinea, no data are currently available. This study was therefore conducted to assess renal morphology and biometry in patients with chronic kidney disease. MATERIALS AND METHODS: This was a retrospective descriptive and analytical study conducted over a one-year period, from January 1, 2022, to December 31, 2022, in the radiology department of Donka National Hospital. The study included records of patients whose ultrasound findings were consistent with CKD during the study period. Files of patients whose ultrasound findings did not support a diagnosis of CKD were excluded. RESULTS: A total of 100 cases were collected, representing a frequency of 75%. The mean age was 49.64 ± 16.28 years (range: 13–80 years). Males predominated with 59% of cases, yielding a sex ratio of 1.43. Nephrologists were the main prescribers (59%). The main indications were renal dysfunction (67%) and edema syndrome (37%). Most patients presented with a hyperechoic cortex (88%) and atrophic kidneys (71%). The mean values of right renal parameters were lower than those of the left kidney. Echographic stages II and III were the most common (35% and 58%, respectively). A statistically significant correlation was found between cortical hyperechogenicity and echographic stages (p = 0.0000).
