The diagnosis of hydronephrosis is made by excretory urography with late films and retrograde pyelography. Renal arteriography in hydronephrosis permits exact evaluation of vascular supply and parenchymal thickness. In three cases selective arteriography was performed because of a non-functioning kidney or suspected space-occupying lesion. The combination of arteriogram and urogram--if necessary together with percutaneous puncture--allows to differentiate between hydronephrosis, avascular tumors, renal cysts, polycystic renal disease, renal abscess, subcapsular renal hematoma, fibrolipomatosis, xanthogranulomatous pyelonephritis, and tuberculosis.

In a new canine experimental model the time concentration relationship of cephalothin in serum, urine, soft tissue interstitial fluid (STIF) and renal interstitial fluid (RIF) were compared simultaneously. Antibiotic concentration in RIF was less than urinary levels but exceeded the serum concentration. Urinary antibiotic concentration does not necessarily reflect concentration in the renal interstitium. This model helps to understand the basic pharmacokinetics of antibiotics in the renal interstitium where pyelonephritis occurs.

The angiographic findings in 13 patients with renal hemangiomas (one pararenal) are presented. The material suggests, contrary to earlier reports, a predominance for the female sex and the right kidney. Nine of the patients had macroscopic hematuria, of which five had renal colic. Obstruction was found at urography in seven cases. Renal angiography is the definitive diagnostic procedure and should be performed in all cases of unexplained macroscopic hematuria. Diagnosis may eventually be improved by pharmacoangiography or by hemodynamic studies using a dye dilution technique, as small arteriovenous shunts may remain undetected at angiography. Cardiac decompensation was not noted in our material, even though arteriovenous shunting within the hemangioma was seen in eight cases, suggesting that the shunt flow in renal hemangiomas usually does not reach levels high enough to impair the general circulation. Hypertension was present in only one patient, attributed to chronic pyelonephritis. Hematuria disappeared in all nine patients operated upon.

Concentrations of prostaglandins of the E and F series were estimated by radioimmunoassay in cerebrospinal fluid (CSF) of 30 febrile patients (infants and adults) and of 19 afebrile, adult patients. In CSF of all feverish patients with meningitis, pneumonia, or pyelonephritis, concentrations of prostaglandins of the E series were about twice higher than those of the afebrile subjects. In contrast, concentrations of prostaglandins of the F series remained largely unchanged during fever. In accord with the results of animal experiments prostaglandins of the E series seem to act as mediators of fever during infectious diseases also in man.

Bone marrow biopsies from the iliac crest in 56 patients with chronic pyelonephritis were evaluated quantitively and correlated with renal function and peripheral blood values (n = 100). In proportion to increasing serum creatinine, mild marrow hypoplasia develops which mainly, and to a statistically significant extent, affects the percentage and amount of erythropoietic cells and megakaryocytes. The simultaneous reduction of erythrocytes and reticulocytes in peripheral blood is more pronounced and only slightly correlated to the marrow cells. There is no correlation between the number of peripheral granulocytes or the decrease in lymphocytes concomitant with uremia, and their respective precursors in the marrow.

The presence of bacteriuria during gestation increases the chance of acute pyelonephritis. Treatment of bacteriuria in pregnancy reduces subsequent development of symptomatic disease. Numerous studies have shown that single-dose therapy for asymptomatic bacteriuria is as effective as longer course of treatment. Single-dose therapy also has the advantages of improved compliance, reduced costs, and less adverse effects resulting from long term therapy. Follow-up cultures following antimicrobial treatment should be used for early detection of recurrence or relapse. If the urine culture yields no growth, a urine culture at a monthly interval will suffice. If on the other hand bacteriuria is present, a repeat course of antimicrobial therapy should be chosen based on antimicrobial susceptibility testing. A longer course of therapy, possibly with a different drug, is recommended for women with a positive follow-up urine culture. Acute cystitis may be treated with the same regimen as asymptomatic bacteriuria. When upper urinary tract infection is suspected, hospitalisation and a longer course of therapy is recommended. If the organism is susceptible to cefalexin or nitrofurantoin, postcoital prophylaxis with either agent for the remainder of the pregnancy may be beneficial.

A man presented with recurrent renal cell carcinoma, complicated with acute pyelonephritis, 3 months status post partial nephrectomy. He underwent cystourethroscopy and a bilateral retrograde pyelogram, then was referred for a Tc-99m DTPA renal study; the images showed an initial photon-deficient area of the right kidney being gradually filled-in by radiotracer with further extension laterally, indicating urinary extravasation. 16 days later this area was aspirated, yielding 5 ml of yellowish fluid with clots consistent with necrotic tumor and pus.

Three cases of pulmonary complications associated with antepartum pyelonephritis are presented, in two of them tracheal intubation and mechanical ventilation were required. All three cases were related to recurrent urinary infections with failure of first line antimicrobial therapy and a concomitant usage of tocolytic therapy. The possible etiology, risk factors and clinical approach, aimed to prevent pulmonary complications in antepartum pyelonephritis are discussed.

Bacillus Calmette-Guerin (BCG) is the most effective agent currently available to treat superficial bladder cancer. However, this form of therapy is not without potential serious or fatal complications. In addition to the potentially toxic systemic side effects attributed to hematogenous absorption of the bacillus, direct upper tract seeding may occur in patients with vesicoureteral reflux. We report on a patient treated with intravesical BCG for bladder cancer in whom unilateral necrotizing granulomatous pyelonephritis developed. Although severe, this complication is rare and we conclude that reflux is not a contraindication for intravesical BCG therapy.

The ureterovesical junction of pigs with cystitis and pyelonephritis was examined. There was significant shortening of the intravesical portion of the ureter in sows with pyelonephritis. In cases associated with acute pyelonephritis the ureteric orifice was found to be significantly wider than that found in the normal population. The ratio of the intravesical length to the ureteric orifice diameter was also significantly reduced. It is postulated that these changes to the ureterovesical junction originate or are caused by the disease processes in the bladder and may allow vesicoureteric reflux to occur, leading to ascending pyelonephritis.
