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.

Parameters of hemocoagulation and fibrinolysis in the blood and urine were studied in 108 children with calculous pyelonephritis. Fibrinolytic inhibition and signs of hypercoagulation were noted. Changes in coagulation were found to be corresponding to the activity of the disease. The changes were mostly pronounced in the urinary fibrinolytic activity, with almost zero levels in those with bilateral nephrolithiasis accompanied by renal dysfunction. Fibrinolytic and anticoagulatory medication was found to be mandatory for the aforementioned patients.

150 patients dying from renal cell carcinoma are studied in order to reveal the background disease, incidence and character of the nephrosclerosis and the possible morphogenetic link between nephrosclerosis and carcinoma. Renal cell carcinoma is found to develop in 82.7% of cases in the kidneys with signs of nephrosclerosis. The diffuse nephrosclerosis developing in connection with the hypertension disease, atherosclerosis, diabetes mellitus, chronic pyelonephritis, nephrolithiasis is the most important. Proliferation of the canaliculi epithelium with the appearance of undifferentiated cells are regularly found in the nephrosclerotic areas. The disturbance of the epithelium differentiation is followed by the development of dysplasia the phenotypical variants of which are similar to those of renal cell carcinoma. Adenomas are found in 11.3% of cases of renal cell carcinoma which may originate from the adenomas developing against the background of nephrosclerosis.

From June 1984 to December 1986 twenty-one benign ureteral stenoses were treated. After percutaneous nephropyelostomy an antegrade dilatation was performed by means of balloon catheters or increasing size of angiographic catheters. Subsequently an ureteral splinting with a F-12-catheter and a glucocorticoid therapy was followed. 13 strictures (61.9%) were treated successfully and in 3 cases (14.3%) an improvement of the obstruction and kidney function was obtained. In 5 patients (23.8%) the dilatation failed, in 2 of whom a nephrectomy was done. The failures occurred in cases with actinic and scarred-fibrotic strictures. The technical procedure, advantages and disadvantages of both dilatation methods were described. Treatment was complicated in 2 patients by the development of nephrolithiasis due to infection and in 2 further patients by acute pyelonephritis. Auxiliary measures of the dilatation therapy are a sufficient diuresis and an effective antibiotic therapy. In conclusion, the results are more dependent on the cause of stricture, than on the duration of disease and the used dilatation technique.

On the basis of a clinical study an analysis about 86 patients with obstructing bilateral nephrolithiasis and chronic obstructive infection of the urinary tract is elaborated. In order to illustrate the change of resistance of the causative agents during a period of 10 years (1973-1982) two separated 5-year analyses are compared. It is made evident that the relations of sensitivity to seven chemotherapeutic drugs in Coli, Proteus and Pseudomonas infections have changed in favour of increasing resistances of causative agents. The results obtained are an expression of the unstableness of antibiotic therapies under palliative purpose when urological basic diseases are not removed. From the analysis the demand for changing the general problems of obstructive pyelonephritis without possible operative sanation becomes evident. early diagnosis and treatment of predisposing factors are the two keystones of our efforts, when the chronic obstructive infection of the urinary tract by resistant causative agents shall not remain a therapeutic problem in the same measure as hitherto.

Some neurophysiological techniques have been employed in clinical nephrology to record abnormalities of nervous conduction in central and peripheral pathways. The electrical monitoring on the peripheral and central nervous systems has allowed the detection of uremic neural injury, the diagnosis of specific electrophysiological abnormalities, the evaluation of various treatments employed and the identification of those abnormalities that uremia can induce. A group of 156 subjects subdivided into four groups were examined: 100 healthy subjects (64 M, 36 F); 56 patients (21 glomerulonephritis, 14 pyelonephritis, 5 nephrolithiasis, 5 polycystic kidney, 4 nephroangiosclerosis, 7 undetermined) with chronic renal failure treated with a conventional low nitrogen diet (CLND, 0.6 g/kg b.w./d. of proteins), 8 of whom passed from CLND to a very low nitrogen diet supplemented with alpha-keto-analogues; a group of 22 of these 56 underwent a regular dialysis treatment for 12 to 15 hours/weekly for 40.5 +/- 10.2 months. Three patients of the CLND group and 13 patients underwent renal transplantation after a variable period of RDT. In the uremic patients we found different populations of motor unit potentials; a decreased MNCV was found in 35% of the CLND patients, RDT patients had slowed MNCV in 42%. The SNCV was compromised more frequently than the MNCV. An increased duration of evoked potentials was sometimes observed in CLND and RDT patients inducing us to consider this a hallmark of uremic syndrome. The alpha-keto-analogues and HD/HP treated patients showed an improvement in several features.(ABSTRACT TRUNCATED AT 250 WORDS)

31 patients with a urological infection caused by a bacterial strain susceptible to gentamycin were treated by a single injection of 240 mg of gentamycin. 11 patients (35.5%) fully recovered, the infection was eliminated and the clinical symptoms and signs disappeared. Better results were achieved in patients with infection of the lower urinary tract without pyelonephritis, 7 out of 15 patients (46%) recovered. Out of 16 patients with pyelonephritis only 4 were cured (25%). Of 10 patients with nephrolithiasis only 1 was cured, in the remaining 9 patients the treatment was without effect. In the group of patients who recovered the patients with E. coli infection prevailed while in the group of unsuccessfully treated patients other bacteria prevailed. No side effects were found. The conclusion is that the treatment with a single gentamycin dose could be applied successfully in patients with an infection of the lower urinary tract without pyelonephritis, morphologic changes in the urinary system or nephrolithiasis.

The incidence of morphological and functional changes of the upper urinary passages and the kidneys obtains 78% in chronic prostatitis. The predominant localisation of the inflammation in the prostate and of the changes on the upper urinary passages and the kidneys on the same side confirms the importance of the chronic prostatitis in the pathogenesis of pathological conditions of the uropoetic system. Chronic pyelonephritis and nephrolithiasis can be proved in 24.5 and 78% of the patients with chronic prostatitis, respectively. Thus, the incidence of these diseases is significantly higher in patients with chronic prostatitis than in patients without such a disease. In 47% of the patients with chronic pyelonephritis and nephrolithiasis a latent chronic prostatitis can be proved, when an exact diagnosis was made.

We report a case of bilateral metachronous xanthogranulomatous pyelonephritis (XGP) in a hemodialyzed patient with end-stage renal failure due to bilateral nephrolithiasis. The XGP was initially diagnosed by computed tomographic (CT) scan, and right nephrectomy was performed. The patient remained clinically stable for the next year. Involvement of the contralateral kidney was again confirmed by CT examination. Both kidneys showed histologic changes compatible with XGP. A coexisting nephrogenic adenoma of the bladder has been attributed to chronic urinary tract infection.
