A total of 150 patients with renal pathology (chronic glomerulonephritis, pyelonephritis, urolithiasis, etc.) accompanied by the development of psychoneurological disturbances were examined. In the initial stage of the renal insufficiency the authors observed neurasthenic, radicular, polyneuritic, renovisceral syndromes, in a more remote stage--encephalopathies and disturbances of the brain circulation. The important part in the above-mentioned disturbances is played by azotemia, metabolic acidosis, disturbances of fluid-electrolyte and albumine balance, as well as arterial hypertension.

Eight cases are reported of female children presenting with hypertension and found to have primary vesicoureteral reflux with chronic pyelonephritis. In 6 patients renal function was essentially normal while 2 had azotemia and progessive renal deterioration. As a result of early surgical intervention in the form of antireflux procedures, occasionally combined with unilateral nephrectomy for renin-dependent lesions, 5 of the 8 had complete disappearance or amelioration of hypertension with stabilization of renal function. The interactions of each member of the triad--vesicoureteral reflux, pyelonephritis, and hypertension--are reviewed with emphasis on pertinent pathophysiologic concepts regarding their roles in the production of progressive renal deterioration.

The parathyroid glands of 14 deceased diabetics were investigated as well as nine control non-diabetics. Various in character and degree histological alterations were observed during the morphological investigations of those glands: mild or better manifested hyperplastic alterations (six cases), microadenoma (one case), focal vasculary determined atrophia (two cases, total atrophia of involutive type (two cases), close to the control alterations (three cases). Hyperplastic alterations are established most frequently in the presence of diabetic nephropathia and azotemia. They could be explained with the development of a secondary hyperparathyroidism, associated with chronic renal insufficiency. In single cases, an effect of the disturbance of the calcium-phosphorus metabolism in diabetes is admitted. Changes in the parathyroid glands, from the type of generalized diabetic microangiopathy, is suspected in one of the deceased patients. Two microadenomas were found in another case, predominantly with dark basic cells. No dependence was established between the morphological alterations and the severity, diabetes form, nor with the presence of pyelonephritis. Certain dependence was established between the age of the deceased and the stage of the azotemia.

Bilateral nephrolithiasis with intermittent ureterolithiasis was diagnosed in a 7-year old Holstein cow. Two episodes of ureterolithiasis resulted in severe azotemia which resolved after spontaneous movement of the stone. A third episode of obstruction one year after the initial episode resulted in rupture of one kidney, necessitating euthanasia. The histopathological examination of the kidney was diagnostic for chronic pyelonephritis. Corynebacterium sp. was cultured from a nephrolith. In this case it is believed that the chronic pyelonephritis predisposed to the calculi formation.

Results of the treatment of 12 patients operated on organs of the abdominal cavity for peritonitis and 2 patients with purulent pyelonephritis are described. The patients had different degrees of disturbances of the renal function (renal insufficiency included). The use of plasmapheresis improved the diuretic function of the kidneys, parameters of glomerular filtration and reduced azotemia. However in patients with the terminal renal insufficiency the including of plasmapheresis and hemofiltration proved to be unsuccessful.

In connection with the analyses of 84 post-mortem examinations (47 men, 37 women, average age: 66.3 years) the author dealt with the renal complications of multiple myeloma. The signs of cylinder nephropathy, light-chain nephropathy, amyloidosis, nephrocalcinosis, urate nephropathy, acute renal insufficiency, renal vein thrombosis, acute and chronic pyelonephritis as well as the tumorous infiltration of the renal tissue have been sought for. The severity of the lesions were ranged into minimal, slight, moderate, and severe groups. On the basis of the semiquantitative morphological picture and the clinical data: 1. intact kidney (41 patients), 2. involvement of the kidney without azotemia (10 patients), 3. involvement of the kidney with azotemia (17 patients, serum creatinine level: greater than 177 mumol/l) and 4. renal involvement with chronic renal insufficiency associated with uremia (16 patients) were discerned. In the background of 33 cases (39%) with deteriorated renal function cylinder nephropathy was found most frequently (27 occasions) (32%). Every other complication occurred significantly less frequently e.g. amyloidosis or kappa-light-chain nephropathy occurred in 3 cases each.

Acute renal failure is a most challenging clinical problem when it occurs in pregnancy. It requires an understanding of the normal physiology of the kidney in pregnancy and the natural history of different underlying renal diseases when pregnancy occurs. Because patients with chronic renal disease may present with worsening proteinuria, hypertension, and renal function, these disorders must be excluded from those conditions that cause acute deterioration of renal failure in otherwise normal women during pregnancy. As in all patients who develop acute renal failure, prerenal and obstructive causes must be excluded. Particularly important causes of prerenal azotemia in pregnancy include hyperemesis gravidarum and uterine hemorrhage, especially if it is unsuspected as in abruptio placentae. Infectious causes of acute renal failure in the pregnant woman include acute pyelonephritis and septic abortion. The clinical presentation of both these conditions should be apparent, and appropriate diagnosis and treatment can then be promptly instituted. Renal cortical necrosis is another cause of renal failure that occurs more frequently in pregnancy, and it must be differentiated from the many causes of acute tubular necrosis that may be associated with pregnancy. Those conditions that cause renal failure unique to pregnancy must always be considered when renal function deteriorates in the last trimester or the postpartum period. Severe preeclampsia, acute fatty liver of pregnancy, and idiopathic postpartum acute renal failure may all present similar complications, but the approach to each of these clinical disorders must be individualized. By understanding the causes of renal functional deterioration in pregnancy, a logical differential diagnosis can be established, allowing appropriate therapeutic decisions to preserve both maternal and fetal well-being.

The historic, physical, laboratory, and histologic findings for 74 cats with chronic renal disease were reviewed. Most cats were older, and no breed or sex predilection was detected. This most common clinical signs detected by owners were lethargy, anorexia, and weight loss. Dehydration and emaciation were common physical examination findings. Common laboratory findings were nonregenerative anemia, lymphopenia, azotemia, hypercholesterolemia, metabolic acidosis, hyperphosphatemia, and isosthenuria. The most common morphologic diagnosis was chronic tubulointerstitial nephritis of unknown cause. The other pathologic diagnoses were renal lymphosarcoma, renal amyloidosis, chronic pyelonephritis, chronic glomerulonephritis, polycystic renal disease, and pyogranulomatous nephritis secondary to feline infectious peritonitis.

290 patients with recurrent urinary tract infection were treated with either placebo, methenamine hippurate, nitrofurantoin or trimethoprim. 38.9% of the patients had chronic pyelonephritis and 23.8% azotemia. During the follow-up period of 1 year 63.2% recurred in the placebo group, 34.2% in the methenamine hippurate group, 25.0% in the nitrofurantoin group and 10.4% in the trimethoprim group. 62.5% of the recurrences in the trimethoprim group were associated with trimethoprim-resistant strains. However, such strains appeared only in 6.5% of the patients treated with trimethoprim, compared with 16.2% in the placebo, 8.3% in the nitrofurantoin and 11.0% in the methenamine hippurate groups. Side-effects were mild and occurred most frequently in the nitrofurantoin group (13.9%).

The authors examined 9015 necropsies, over the age of 14, in a general hospital for the period January 1, 1967 to March 1, 1979. They found that the chronic pyelonephritis (ChPN) was the most frequent renal diseases with a lethal end--62.83 per cent of the renal patients and 7.95 per cent of all deceased. In 458 (63.87%) of them ChPN was accompanied by arterial hypertension (AH), which with an average duration of 8.8 years had caused a considerable hypertrophy of left ventricle. A better manifested atheromatosis of aorta, coronary, cerebral and renal arteries, being statistically significant, was found in the deceased with ChPN and AH as compared with the control group of 524 subjects, deceased without hypertension but that atheromatosis was less manifested than in those that died of hypertonic disease. That fact was explained by the authors with the shorter duration of hypertension in ChPN, with a more strict nutritional regimen among them, with the shorter life span and azotemia, as well as with the more active involvement of adrenergic systems of the patients with ChD. Whereas in 2/3 of the deceased with ChPN, without hypertension, the cause for the lethal end was uremia and urosepsis, the incidence of cardiac and cerebral-vascular complications, in those deceased with ChPN and AH, was 6 times greater than the first and uremia and urosepsis--considerably less frequent.
