One hundred and eight patients suffering from hypertension due to a unilateral parenchymatous neophropathy were studied over a period of one to eight years after treatment was starded. The aetiologies were diverse: harmonious hypoplasia, segmental hypoplasia, pyelonephritis, reflux nephropathy, hydronephrosis and tuberculosis. Thirty nine patients were treated surgically, with 50% good results. In 82 cases medical treatment was continued for at least a year with a 52% success rate. Such success was recorded in 94% of cases in which beta-blockers were used (38 cases). Surgical success was not dependent upon the period for which hypertension had been present. The best results were seen in cases of hydronephrosis and pyelonephritis and the worst in tuberculosis. Thirteen patients underwent surgery event though there was no unilateral increase in plasma renin levels. Seven were improved or cured. Ten patients underwent surgery with a renin activity 50% greater than on the healthy side, 9 being improved or cured. Treatment with beta-blockers, alone or in association with diuretics, controlled blood pressure in 90% of cases, regardless of the renin activity. Plasma renin activity in the renal veins is of good prognostic value in terms of the effectiveness of nephrectomy against hypertension. In Call cases, beta-blockers were more effective than surgery.

The results of a retrospective autopsy study of 115 adult patients with haematological or lymphoreticular malignancies or who had undergone transplantation procedures, are presented. The overall incidence of infection was 65%, 123 infections being detected in 75 patients. The bulk of the infections involved the gastro-intestinal and respiratory systems, other systems being considerably less frequently affected. Patients who had received allografts and subsequent immunosuppression had the highest incidence of viral inclusions, especially cytomegalovirus. Candida infections were more common than aspergillosis, and severe fungal infections were most frequent in patients with acute leukaemia who had been treated aggressively. The only other mycosis detected was cryptococcosis. Bacterial pneumonia was the most frequent infection over-all (36%). Tuberculosis, pyelonephritis and Pneumocystis pneumonitis were also encountered.

Sera from 103 fasting individuals 3 to 76 years of age and free of clinical infectious disease and sera from 183 patients with infectious disease were assayed for serum total non-esterfied fatty acids (tNEFA) and compared. Data were also separated into five groups according to age of donor: 3--7, 8--19, 20--35, 36--60, and 61--76 years. The mean group serum levels of tNEFA increased with age. Among patients with infectious diseases sixty-five were diagnosed as having hepatitis, 41 with infectious mononucleosis, 18 with cellulitis, 12 with pulmonary tuberculosis, 11 with non-pneumococcal pneumonia, 9 with pneumococcal pneumonia, 8 with pharyngitis, 6 with pyelonephritis, 6 with aseptic meningitis, 4 with Gram-negative sepsis, and 3 with encephalitis. The sera from 23 non-fasting patients with gonorrhea were also tested. The serum tNEFA levels were found to be altered, in fact depressed from normal group values, only in patients with pneumonia or tuberculosis. This depression may be related to aberrant pulmonary metabolism during pneumonia.

Roentgenologic procedures are of limited value, compared with other possible examinations. Early radiologic diagnosis is made rarely. Roentgenologic procedures are important for demonstration of successful treatment and for legal documentation. Excretory urography is effective only in combination with zonography and ureteral compression provided the amount of injected contrast medium is sufficient. Angiography is important in progressive or silent renal tuberculosis, especially in cases of a partial or complete non-functioning kidney. Difficulities in differential diagnosis are possible in unspecific pyelonephritis and malignant tumors.

The diagnostic tactics in the clarification of urogenital tuberculosis are referred to the changes for the individual examinations mentioned. Some tables show the results of radiological investigations on 200 patients with proved renal tuberculosis, the extend of the triple staging proposed by us being specified. In addition to expositions on the radiopathology of urogenital tuberculosis, the differential diagnosis is indicated, its focus lying in the comparsion of 118 patients with clinical-bacteriological and/or histologically confirmed non-specific chronic pyelonephritis. The comparison of patients from two 3-year groups 1959-1961 and 1971-1973 as well as between natives and foreigners shows a change in the clinical radiological picture of renal tuberculosis.

Whether chronic interstitial nephritis (pyelonephritis) mainly results from kidney infection is widely debated. We studies 101 patients with interstitial nephritis, selected from 320 patients with newly diagnosed chronic renal disease, for frequency of etiological factors. Eleven had no etiologic factor(s) identified; 89 had clearcut factor(s): anatomic abnormalities 31, analgesic abuse 20, hyperuricemia 11, nephrosclerosis 10, stones 9, sickle cell disease1, tuberculosis 1, multiple causes7. Bacterial infection (present in 27%) was found only with another preceding primary cause of renal damage. Analgesic abusers frequently denied drug ingestion; 15% had urinary tract infection and 20% classical papillary necrosis. Two had family histories of analgesic abuse with nephropathy. We conclude that interstitial nephritis is a common form of chronic renal disease, is seldom idiopathic, rarely results from bacterial infection alone in adults, and frequently results from analgesic abuse in the United States.

The study of sex distribution revealed an increase of the percentage of females among more than 12 000 patients with pyelonephritis, renal tuberculosis and nephroureterolithiasis in the period 1959-73 from 69 to 75%, from 63 to 69% and from 54 to 64%, respectively. The tendency revealed may be explained by a decrease of the role of general causal factors, which are of the same importance for males and females, and by the relative increase of the role of local factors, which are of greater importance for females due to pregnancy, delivery, and gynecological disorders. The role of the latter factors in the pathogenesis of infectious and calculous renal diseases in women is confirmed by the study of the history and the fate of female patients and by a more frequent affection of their right kidney. Women after complicated pregnancy and delivery, gynecological diseases and genital surgery need regulat dispensary urological observation to prevent and detect early infectious and calculous renal diseases.

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.

The rapid-sequence intravenous urogram (IVU) has tended to fall from favour for investigating hypertension because of its perceived imprecision for detecting renovascular disease. However, no study has examined the value of the IVU as a screening test in appropriately selected patients. We have analysed the diagnostic yield of the rapid-sequence IVU in hypertensive patients selected for features suggesting renal or renovascular disease in a retrospective review of case records from a hypertension clinic. The IVU was abnormal in 27% (95% CI 21-32%) of 241 consecutive patients. The most common abnormalities were chronic pyelonephritis (6%); proven renovascular disease (5%); stone (4%); possible renovascular disease and simple cyst (each 3%); hydronephrosis (2%); and tumour and active tuberculosis (each 1%). The IVU led to intervention aiming to correct hypertension in 5% (95% CI 2-8%) of patients, and revealed an abnormality needing intervention in its own right in 4% (95% CI 2-6%). The IVU led to unnecessary invasive investigation in 3% of cases. Individual abnormalities could not be predicted from the clinical or laboratory features. The initial investigation in hypertensive patients with suspected renal or renovascular disease should be a general purpose test able to detect a wide range of abnormalities. The rapid-sequence IVU is the only single test capable of satisfying this requirement. In patients with features suggesting renovascular disease, a normal rapid-sequence IVU excludes renovascular disease with 93% probability, but is an imperfect screening test since it fails to diagnose about 20% of cases. Renal arteriography should be done despite a normal IVU when it is essential to exclude renovascular disease.

This report describes a 40-year-old man with an unusual form of granulomatous pyelonephritis, associated with nephrolithiasis, resulting in end-stage kidney disease and right pretransplant nephrectomy. The kidney specimen contained a staghorn calculus and showed chronic inflammation with confluent caseating granulomas and multinucleated giant cells, resembling renal tuberculosis. However, neither tubercle bacilli nor other microorganisms were demonstrated in the renal tissue or in urine cultures. Because these findings do not support a tuberculous etiology of the granulomatous pyelonephritis, we conclude that this patient had a pseudotuberculous reaction as a consequence of nephrolithiasis.
