BACKGROUND To assess and to compare the renal volume evolution in bitches during pregnancy by two-dimensional (2D) ultrasonography using the ellipsoid technique (volume = length x width x depth x 0.523) and three-dimensional (3D) ultrasonography using the Virtual Organ Computer-aided AnaLysis (VOCAL) method. A longitudinal prospective study was performed with 17 normal Golden Retrievers bitches...

Hepatorenal failure, a well-recognized complication of established liver disease, is characterized by early renal hemodynamic changes (vasoconstriction) before clinically recognized kidney disease. This renal vasoconstriction (increased renal vascular resistance) should be detectable noninvasively by Doppler ultrasonography. We studied whether renal Doppler ultrasonography detects abnormalities...

Ultrasonography is a quick and non-invasive method of evaluating the kidney which cannot be seen on excretory urography. If advanced renal tuberculosis is the reason, then ultrasonography is frequently diagnostic.

OBJECTIVES Recently, several authors reported that Tc-99m DMSA renal scan frequently showed cortical defects of the involved kidneys even in the patients with acute pyelonephritis who did not show abnormal findings in the ultrasonography and intravenous pyelography (IVP). METHODS In order to evaluate the utilities of Tc-99m DMSA renal scan and the clinical meaning of cortical defects in the T...

  The common use of maternal ultrasonography has increased the apparent incidence of neonatal hydronephrosis. Many of these cases are found to have partial obstruction at the ureteropelvic junction (UPJ). These patients are safely managed in our institution with careful observation and only occasionally require surgical intervention. The authors present two contrastin...

INTRODUCTION We report on the successful endovascular treatment of a ruptured splenic artery pseudoaneurysm. Our patient had acute pancreatitis superimposed on chronic calcific pancreatitis and chronic renal impairment. Contrast-enhanced ultrasonography was used to assess post-embolization results. CASE PRESENTATION Our patient was a 67-year-old white Caucasian man with recurrent pancreatitis...

Ultrasound is very sensitive in diagnosing obstruction by demonstrating hydronephrosis (1, 2). Ultrasonography has great advantage over IVU in patients who have azotemia, contrast materialinduced allergy, are pregnant, fetal, or pediatric patients with no exposure to radiation. And ultrasonography can nicely visualize the both the renal parenchyma and the collecting system as well as causative ...

BACKGROUND Hydronephrosis is the one of the most common congenital abnormalities of urinary tract. The left kidney is more commonly affected than the right side and is more common in males. AIM OF THE STUDY To determine the role of ultrasonography, renal dynamic scintigraphy and lowerdose computed tomography urography in preoperative diagnostic workup of infant with extreme hydronephrosis. ...

A case of renal tubular acidosis (RTA) who had gradual onset of paralysis of lower extremities and persisted for a long time is presented. His primary workups were mistaken for muscular dystrophy. Eventually, an abdominal ultrasonography revealed small stones in both of the kidneys and his workup for the stones were in favor of distal renal tubular acidosis and advanced rickets with hypokal...
