In a national survey, chronic renal failure (CRF) in Swedish children was studied during the period 1986-1994; 118 children (72 boys, 46 girls) with CRF, defined as a glomerular filtration rate below 30 ml/min per 1.73 m2 body surface area, were identified. The median annual incidence of CRF was 7.7 and that of terminal renal failure (TRF) 6.4 per million children. The prevalence of preterminal renal failure decreased from 29 to 21 per million children over the study period, while the prevalence of TRF increased from 17.8 in 1986 to 38 per million children in 1994. The increase in TRF prevalence was due to a lower incidence of deaths due to uremia and a slightly increased incidence of TRF compared with an earlier study period, 1978-1985. The results point to a more active treatment of uremia in Sweden now than during the period 1978-1985. The congenital causes of CRF (renal malformations, obstructive conditions, and hereditary disorders) accounted for 67.5% of all cases, which is high compared with data from other countries. No child with non-obstructive pyelonephritis as a cause of CRF was identified. Age at detection of CRF and time from detection of CRF to TRF were studied. As a high proportion of children, 42%, reached 16 years of age without entering TRF, the value of presenting time from CRF to TRF for the remaining individuals is questionable. There were only minor differences in primary renal disease, age at presentation, and time from CRF to TRF when the study results were compared with those from 1978-1985.

Glycosaminoglycanes (GAG) were measured in 24-h urine of patients with chronic pyelonephritis (CP) and chronic glomerulonephritis (CGN) at different stages of nephrosclerosis. These patients developed hyperglycosaminoglycanuria at early stages of nephrosclerosis before establishment of chronic renal failure. There is a positive correlation between the severity of excretion of GAG and leukocyturia in CP patients (p < 0.05). Estimation of GAG 24-h urinary excretion can help evaluate metabolism of connective tissue of the kidneys in CP and CGN patients for early diagnosis of nephrosclerosis, control of the treatment efficacy and the disease prognosis. It can also serve as additional criterion for rating of inflammation. The method is non-invasive, informative, available for clinical diagnostic laboratories.

Post-transplant neutrophilic interstitial nephritis (NIN) is characterized by an interstitial infiltrate consisting of polymorphonuclear cells that leads frequently to acute graft dysfunction. In 220 graft biopsies performed because of renal dysfunction over 2 years in our unit, 11 (5%) diagnoses of NIN were made. Only two patients had chronic pyelonephritis as original disease. Four patients had urological problems before transplantation. After transplantation, five patients had urinary tract infection, one had urethral stenosis, two had vesicourethral reflux and one patient had a perinephritic abscess. Seven patients had fever (63%). Only in six patients did urine culture lead to microorganism isolation. After 6 months, only two patients had a serum creatinine level < 1.4 mg/dl, five patients had abnormal function, three had lost their grafts, and one patient had died with sepsis. We conclude that 5% of the biopsies performed in our center disclosed NIN, an entity that causes graft dysfunction and progresses frequently to chronic renal failure. In some cases, no infectious etiology could be detected.

Analysis of the changes in the levels of total prostatic specific antigen (t-PSA) in patients with benign prostatic hyperplasia (BPH) shows that the patient's age, size of the prostatic gland and chronic bacterial prostatitis influence the levels of t-PSA but have no effect on the levels of PSA-ACT. The relationship between the levels of t-PSA and age in BPH patients is explained by growing mass of benign hyperplasia causing mechanical load on the intact prostatic tissue. The maximal concentration of t-PSA of 8.7 +/- 1.22 ng/ml was observed in BPH patients at the age of 61-70 years. BPH stages, chronic pyelonephritis, chronic non-bacterial prostatitis, chronic renal failure are not essential for t-PSA and PSA-ACT and can be neglected in interpretation of t-PSA values in BPH patients.

In patients with inoperable cancer of the urinary bladder complicated by uretherohydronephrosis, chronic pyelonephritis, chronic renal failure, profuse bleedings from the tumor and pronounced dysuria, the supravesical derivation of urine is thought to be vitally indicated in spite of the unfavourable prognosis of the basic disease. First, it is necessary to provide the adequate drainage of the upper urinary ducts and kidneys followed by making favourable conditions for their longer and good functioning.

Urinary tract infections are one of the most common renal diseases sometimes leading to renal injury and in consequence to chronic renal failure. The most frequent causative pathogen responsible for this infection is Escherichia coli. There are several factors which increase the risk of infection including vesicoureteral reflux, cystic renal disease, urinary calculi, obstruction and other anatomical and functional abnormalities of urinary tract as well as neurological bladder dysfunction, long term indwelling catheters, mechanical vaginal diaphragms and intensive sexual intercourse. This paper will highlight general view on the treatment of different manifestations of urinary tract infections including asymptomatic bacteriuria, urethritis, cystitis, prostatitis as well as acute and chronic pyelonephritis. The details of those problems will be elucidated in another paper.

Hearing function was assessed in 63 patients with pronounced chronic renal failure (40 males, 23 females aged 20-52 years). Chronic renal failure resulted from chronic glomerulonephritis in 34 patients (16, 10 and 8 cases of nephrotic, hypertensive and mixed form, respectively), chronic pyelonephritis in 29 patients. The acoustic function was evaluated using acumetric methods, tonal threshold and suprathreshold audiometry, ultrasound sensitivity test, speech audiometry. Hearing disorders detected in patients with chronic renal failure were moderate and were characterized as neurosensory hypoacusis. The defects concerned high frequency perception. Hearing thresholds were high in all the examinees.

Progressive chronic pyelonephritis (CPN) leading to renal failure was, in the past, a mode of death in children with meningomyelocele (MMC). With more sophisticated management modalities, renal failure is now uncommon, but the problem of CPN still remains. In this series of 100 children with MMC, 39% have CPN. It is significantly more common in girls than in boys. There is a strong relationship between CPN and vesico-ureteric reflux (VUR). There is no association with raised bladder pressure. The majority of CPN arises in children under the age of 4 years, but damaged kidneys can continue to deteriorate. Although chronic renal failure is rarely seen in children with MMC, there is a risk that this may merely be postponed into adulthood.

An adolescent with a history of pyelonephritis and renal scarring had antireflux surgery at the age of 2.5 years. His serum creatinine was high at the age of 14 years (133 micromol/l; glomerular filtration rate (GFR) 56 ml/min x 1.73 m(2)), and reflux nephropathy with chronic renal failure was diagnosed. Because of a fall in height velocity, endocrinological investigations were performed six months later which showed hypothyroidism caused by autoimmune thyroiditis. Substitution with thyroxine was started; renal function improved to normal six months later (GFR 108 ml/min x 1.73 m(2)). Metabolic changes of hypothyroidism led to a reduction of GFR in this patient and mimicked chronic renal failure.

Icterohemorrhagic spirochetosis convalescents develop slowly regressing renal dysfunctions most frequent of which are chronic renal failure, pyelonephritis and tubulointersticial nephritis, arterial hypertension. Renal disorders may be due to immunopathological reactions followed by activation of bacterial microflora. Damage from commissures at the sites of prior hemorrhage is also possible. In bovine leptospirosis renal damage is not so severe but it tends to progression. So, renal affection in leptospirosis is a specific pathology observed in any clinical form of the disease and demands surveillance in the regions of local focuses.
