A 38-year-old woman presented with fever, right flank pain, and a clinical diagnosis of pyelonephritis. Work-up revealed the presence of a crossing arterial branch causing obstruction of the superior infundibulum of the right kidney, which is an uncommon cause of nephralgia and urinary infection initially described by Fraley in 1966. Intravenous urography, retrograde pyelography, and angiography remain the mainstay of diagnosis, much as in the initial descriptions of this entity. [131I]Hippuran imaging, with analysis of the upper and lower pole regions of interest, provides a simple yet powerful method of evaluating functional and excretory changes in the superior infundibulum, and has proved more efficacious than previously reported whole-kidney renograms. Renal scintigraphy represents a relatively noninvasive method of serial functional examination in this disorder. Ultrasound imaging, by monitoring upper-pole dilatation, may provide complementary morphologic information important for long-term follow-up.

A 14 year old boy was admitted for vomiting, anorexia, flank pain and leukocyturia/hematuria. Shortly after admission, he developed anuria and acute renal failure so that hemodialysis had to be started. Pre- and post-renal causes were excluded. There were no signs of acute glomerulonephritis; liver enzymes were normal. The 123Iodine-Hippuran scan showed a shock kidney pattern lacking tubular clearance. Renal biopsy revealed an interstitial nephritis with edema and a mixed cellular infiltration. History was empty for nephrotoxic agents except for mushroom ingestion: Five days before admission the boy ate Cortinarius speciocissimus mushrooms, the toxine of which is known to be nephrotoxic, causing irreversible renal failure in severe cases (Orellanus Syndrome). Renal function did not improve much and renal transplantation was performed after 14 months on hemodialysis. In interstitial nephritis of unknown etiology the possibility of mushroom poisoning should be considered.

The value of ultrasound and 131-Hippuran renography for diagnosing hydronephrosis during pregnancy was investigated. In a control series of 31 symptom-free pregnant women the ultrasonographically measured renal pelvic diameters in the three trimesters were 5, 10 and 12 mm on the right side and 3, 4 and 5 on the left, respectively. In ten healthy non-pregnant women the pelvic diameter varied from 3 to 9 mm on the right side and from 2 to 6 mm on the left side when measured during antidiuresis and water diuresis. Out of 35 pregnant women complaining of flank pain, 31 showed an increased renal pelvic diameter. These 35 women also underwent renography on the same day as the ultrasound examination. In 6 of 27 pregnant women with right-sided pain and in 3 of 8 with left-sided pain, diuresis renography indicated acute ureteral obstruction and in 6 of these 9 patients impairment of renal parenchymal function was also evident. In some cases the impaired renal function was fully reversed after surgical intervention. It is concluded that ultrasound investigation of the kidney is a valuable method for screening prior to renography. Since the negative prediction value of using 17 mm as the upper limit of the pelvic diameter was 100%, patients with a smaller pelvic diameter may not need to be referred further for renography or urography, and radiation will thus be minimized. On the other hand, renography is indicated when the pelvic diameter is more than 17 mm in patients complaining of flank pain.(ABSTRACT TRUNCATED AT 250 WORDS)
