“…The sonographic features like hyperechoic medullary rim are suggestive of nephropathy [11] and marked renal pelvic dilation with central anechoic space and atrophy of renal parenchyma following longstanding ureteral obstruction [10, 12] in hydronephrosis have been documented. Hydronephrosis have also been sonographically categorized as narrowed renal parenchyma with its structures still discernible in mild hydronephrosis to more thin homogenous renal parenchyma in advanced hydronephrosis [13]. According to this classification, the dog in the present study was affected with advanced degree of hydronephrosis.…”

The present study comprises of 10 dogs of either sex with primary indication of azotaemia. All the dogs were subjected to detailed clinical, haematobiochemical, urinalysis, and microbiological examination along with radiographical and ultrasonographical examination. Based on the ultrasonographic structural abnormalities, the different renal affections associated with CRF in majority of dogs were diagnosed. The different affections included “end-stage” kidneys (n = 4), hydronephrosis (n = 1), renomegaly (n = 1), nephritis (n = 1), nephrolithiasis (n = 1), nephrocalcinosis (n = 1), and renal cyst (n = 1). The significant ultrasonographic features in these affections included small kidneys with loss of corticomedullary demarcation (“end-stage” kidneys); increased cortical echogenicity (nephritis); dilation of the renal pelvis, separation of the central renal sinus with anechoic space, atrophy of renal medulla, (hydronephrosis); enlarged kidneys with increased overall echogenicity of renal cortex (renomegaly and associated nephritis); hyperechoic-mineralized structure with shadowing (nephrolithiasis); diffuse, small, multiple hyperechoic structures in the renal parenchyma with distal acoustic shadowing (nephrocalcinosis); small spherical intercortical anechoic structures fluid (renal cysts). In the present study, ultrasound proved to be a quick, convenient, and sensitive modality in detecting alterations in renal size and parenchymal architecture. All the dogs so diagnosed with CRF were rendered conservative medical treatment to control clinical signs of uraemia; maintain adequate fluid, electrolyte, and acid/base balance; provide adequate nutrition; minimize progression of renal failure.

“…2,14,23,24,73,85 Mild, unilateral pelvic dilation has been observed with saline diuresis or secondary to increased urine flow when the contralateral kidney was badly diseased or missing. However, current high-resolution ultrasound equipment allows visualization of mild pelvic dilation during diuresis in normal animals (pyelectasia).…”

“…73 If the dilation is more than 3 to 4 mm, diuresis is considered less likely and further investigation is warranted to rule out disease. This kidney is enlarged and there is increased echogenicity of the renal cortex (C) in this cat with renal lymphosarcoma.…”

“…Ureters are not normally identified throughout their entire length on single radiographs because of peristaltic emptying of the radiopaque urine (19). Two-dimensional, gray scale ultrasonography can complement data obtained from other diagnostic modalities, including survey and contrast radiography (7,9,10,13,15). In the diagnosis of renal disease in the dog, ultrasonography has many advantages over conventional radiographic procedures.…”

Summary:The objectives of the present study were to describe the complementary use of radiography and ultrasonography in the diagnosis of upper urinary tract disorders in dogs, and to compare ultrasonographic findings with the survey and contrast radiographic findings in the evaluation of canine upper urinary tract diseases. The study materials were composed of 22 dogs of various breed, age, and sex with upper urinary tract diseases. Pyelonephritis (9 cases), acute renal failure (7 cases), policystic renal disease (2 cases), bilateral hydronephrosis (one case), radiopaque nephrolith (2 cases), unilateral ectopic ureter (one case) were diagnosed radiographically and ultrasonographically. The results of the present study indicate that ultrasonography was more sensitive than radiography in diagnosis of upper urinary diseases but was incapable in qualitative evaluation of renal functions and in examination of the ureters. Survey radiographs had little value in the diagnosis of pyelonephritis, disorders of renal pelvis, ureters except for the identification of radiopaque nephrolith. It was determined that EU was valuable for determination of the ectopic ureter, hydronephrosis, and evaluation of renal function.
