Quistes renales simples diagnosticados con tomografía multidetector y factores asociados. Hospital José Carrasco Arteaga. Cuenca, 2017

Abstract

Background: Simple renal cysts are closed sacs that have a thin and smooth wall, contain liquid, which is homogeneous, with a density similar to water, whose clinical significance is still uncertain. Objectives: To determine the prevalence of simple renal cysts diagnosed with 64-channel multidetector tomography and associated factors in the José Carrasco Arteaga Hospital. Methodology: An analytical cross-sectional study will be carried out, with the patients that go to the area of Imaging for the performance of a tomographic study of simple abdomen, in a simple random sample of 416 patients, during the period January-December 2017. The exam was carried out with a 64-slice Multidetector Tomography. Results: The prevalence of simple renal cysts was 22.11%, with a mean age of 51.3 ± 16.2 years, of which the male sex represented the highest proportion (58,73%). The simple renal cyst was more frequently unilateral (77,17%), and predominantly localized to the right side and peripherally (86,95%). The majority had a size smaller than 20mm (64,13%), in addition the average diameter of the largest cyst was 19,18 ± 14,75 mm, with a range of 3 to 66 mm. We found a significant association of simple renal cysts with type 2 diabetes mellitus (p = 0.020), arterial hypertension (p = 0.000) and decreased renal function (p = 0.000). Renal lithiasis did not present statistical significance (p = 0.120).
