Evaluation of Renal Morphology for Patients on Hemodialysis Using Ultrasound

Abstract

This study set out to determine renal morphology in patients with chronic renal failure whom had been on haemodialysis , using ultrasound. In this study, 55 patients with CRF and on HD, were studied by ultrasonography which is accepted to be the most suitable noninvasive technique for the estimation of renal morphology .We use ultrasound scanner (Mindray (DP-3300) China ), and (2.5- 5 ) MHz sector transducer .This had been done at Kosti Teaching Hospital– Renal Dialysis Center.The kidney length ,width and thickness were measured using electronic caliber ,and kidney volume was calculated using the formula : kidney volume = kidney length ×kidney width × kidney thickness × 0.523 . Renal shape index was calculated using the formula : kidney shape index = kidney length ÷ ( kidney width + kidney thickness ) . Of the study group , 58.2% were males and 41.8% were females , their ages were ( 47.3 ± 16.6 ) years ,weight (52±15.3) kg. and have been on dialysis for (2.8± 2.1) years. This study conclude that , the right kidney found to be more echogenic than the left kidney and the left kidney is more liable to cystic degeneration than the right kidney . In this study, it has been noticed that there is a negative and significant correlation between kidney volume and dialysis duration on both kidneys , and there is positive correlation between the patient age and kidney volume . Our data also showed that kidney volume has positive correlation with patient weight .
