Comparative evaluation of intravenous urogram and ultrasound in prostatism.

The combination of renal ultrasound, abdominal scout film, and urine analysis detected all significant renal pathology in 53 patients before surgery for prostatism. It is suggested that these combined examinations in conjunction with a blood urea nitrogen determination can replace urography in the preoperative screening of these patients.

Pancreatic pseudocysts presenting as thick-walled renal and perinephric cysts.

Posterior extension of a pancreatic pseudocyst should be considered in the differential diagnosis of a thick-walled renal or perinephric cyst seen on infusion pyelography with tomography. Opacification of the wall of a pancreatic pseudocyst by this technique has not been reported previously and lack of knowledge of this possibility can lead to mistaken diagnosis and the possibility of an unnecessary exploratory operation, particularly when angiography is inconclusive and a gastrointestinal series is negative or equivocal. The mechanism of opacification of the wall of a pancreatic pseudocyst is discussed. Parasitization of the renal capsular arteries by a pancreatic pseudocyst can further compound the difficulty of diagnosis.

Acute adult onset bacterial nephritis: long-term urographic and angiographic followup.

Most adults with acute bacterial renal infection demonstrate no roentgen abnormality in the acute stage and recuperate without significant functional or morphological renal abnormality. We report the initial and long-term findings in a virulent form of acute bacterial nephritis caused by gram-negative organisms and predominantly in patients with diabetes and associated septicemia. The findings of a small, poorly functioning symmetrically scarred kidney with significant caliceal distortion and the associated angiographic abnormalities are presented for the first time in the long-term followup of this disease.
