The clinical course of 138 children who underwent unilateral nephrectomy and had a normal contralateral kidney at the time of nephrectomy was reviewed. The diagnosis leading to nephrectomy included obstructive uropathy in 46% of the cases, reflux or
pyelonephritis
in 30%, Wilms tumor in 15%, hypertension in 4%, dysplastic kidney in 2% and trauma in 2%. Mean age at nephrectomy was 7.3 years and median followup was 24.7 years. Of the 138 patients 121 (88%) are well and 17 died, including 14 secondary to metastatic Wilms tumor and 1 of renal failure. Survival of nonWilms tumor patients was similar to that of an age-matched control group. In 30 patients 24-hour creatinine clearance and 24-hour urinary protein excretion were measured.
Proteinuria
(greater than 150 mg./24 hours) was found in 8 of the 30 patients (27%) (p less than 0.001), renal insufficiency developed in 9 (30%) (p less than 0.0001) and hypertension occurred in 10% (p greater than 0.10). Children with an acquired solitary kidney are at increased risk for
proteinuria
and renal insufficiency.

Obstetric complications recorded prospectively were assessed retrospectively in 150 women with gestational diabetes mellitus (GDM) and 305 control subjects matched for age, parity, and ethnicity. Intensive diet therapy and self-monitoring of capillary blood glucose were used to obtain postprandial euglycemia; 22% of GDM subjects required insulin. GDM and control subjects were grouped by body mass index to detect any influence of maternal prepregnancy weight on outcome. Polyhydramnios, preterm labor, and
pyelonephritis
were not more frequent in GDM, but hypertension without
proteinuria
(7.3 vs. 3.3%) and preeclampsia (8 vs. 3.9%) were more frequent in GDM. The frequency of hypertensive complications in GDM was not totally attributable to being overweight. Abnormalities of labor, birth trauma, and fetal macrosomia were not more common in GDM; 6.7% of the infants of mothers with GDM weighed greater than 4200 g at birth compared with 3.6% of control infants (NS), and 10% were large for gestational age and sex compared with 6.6% of control infants (NS). Despite this, cesarean delivery was more common in GDM (35.3 vs. 22%, P less than 0.01), mostly due to significantly more cesarean births without labor.

196 cases with vesicoureteral reflux (VUR) from multiple centers were analysed to examine the relationship between VUR and reflux nephropathy. The high correlation (p less than 0.01) was observed between reflux and renal scarring. Even in cases in whom VUR was not demonstrated at the time of testing, renal scarring of various degrees was recognized, suggesting either co-existed hypoplastic kidney or pre-existed infection. The renal scarring, but not VUR, had a significant correlation with
proteinuria
and hypertension. Retrospective analysis shows that the surgical treatment was closely related to the degree of renal scarring but not to the degree of reflux. Renal scarring progressed even when reflux did not become worse, which is probably accounted for by the presence of
pyelonephritis
. Although frequency of
pyelonephritis
decreased significantly (p less than 0.01) from 0.60 +/- 0.89 to 0.084 +/- 0.305 times/patient. year after anti-reflux surgery, renal scarring progressed in 13 kidneys (5.8%). Seven of the 13 kidneys became worse due to the surgical failure. The scar progression was recognized in the remaining six kidneys (three patients) including adult cases despite the successful surgical correction of reflux. Our study points to the urged need for a prospective clinical trial designed for the study of the pathological and clinical background of progressive renal failure in VUR.

The analysis of urinary proteins and their identification are discussed, particularly in regard to the technique of sodium dodecyl sulphate electrophoresis in polyacrylamide gradient gels. Urine collection, storage and preparation are evaluated, especially in regard to problems connected with concentration and dialysis of such samples. The instrumental approach to sodium dodecyl sulphate polyacrylamide gel electrophoresis represented by the Phast System appears to be particularly valuable in routine clinical analysis of urine specimens, since no sample pretreatment is required. The following types of proteinurias are evaluated: (a) orthostatic proteinurias; (b) post-renal proteinurias; (c) Bence-Jones
proteinuria
; (d) lower and upper urinary tract infection (cystitis and
pyelonephritis
) and (e) diabetes mellitus proteinurias.

Fifty women with pyelonephritic renal scarring were prospectively followed for five years and the changes in renal function were related to blood pressure control, plasma renin activity, urinary albumin excretion and the incidence of urinary tract infections (UTI). Five patients (10%) developed end stage renal disease. All these patients had bilateral disease,
proteinuria
and anti-hypertensive treatment at presentation. The mean +/- SD glomerular filtration rate (GFR) of all patients with renal scarring was 74 +/- 27 ml/min x 1.73 m2 at presentation which was significantly lower than the GFR in 55 patients with a recent episode of acute
pyelonephritis
(p less than 0.001) and 10 healthy controls (p less than 0.001). GFR and age corrected GFR decreased significantly during follow-up (p less than 0.001) and p less than 0.02 respectively). The decrease in GFR was significantly higher in patients with bilateral scarring, in patients on blood pressure treatment and in patients with an episode of symptomatic UTI during follow-up. Eight patients (16%) had antihypertensive treatment at presentation and another 11 patients (26%), of whom 10 had bilateral scarring, developed hypertension (greater than 140/90 mmHg) during follow-up. Seventy-five per cent of all patients had symptomatic UTI and 40% had an episode of acute
pyelonephritis
during follow-up. In conclusion, patients with pyelonephritic scarring have a high incidence of UTI and are at high risk of developing renal failure and hypertension. It is essential that recurrent episodes of symptomatic UTI are treated promptly and that blood pressure is monitored carefully in these patients.

Experimental and spontaneous infections with Corynebacterium suis in sows were investigated. In early stages animals show no clinical disorders or only for a short time. However, there are already marked changes in urinary samples (hematuria,
proteinuria
, leukocyturia, gross alterations). Using an endoscope mucosal irritations can be seen mainly on the floor of the bladders. In chronic cases alterations in urine are more pronounced. If a
pyelonephritis
is present in addition to the cystitis, general signs of illness are evident including anorexia, emaciation, anemia, subnormal body temperature and abortions. Bladders demonstrate an erosive and ulcerative, hemorrhagic cystitis on the whole mucosal surface. Uremia appears only in late stages of the disease.

The urinary excretion of alpha 1-microglobulin (alpha 1M), beta 2-microglobulin (beta 2M), retinol-binding protein (RBP) and N-acetyl-beta-D-glucosaminidase (NAG) as markers of proximal tubular dysfunction was measured in various forms of urinary tract infections (UTI) and in fever due to non-renal infections. The urinary concentration of these proteins was significantly increased in acute
pyelonephritis
compared with acute cystitis and asymptomatic bacteriuria. Tubular
proteinuria
and enzymuria could also be demonstrated in subjects with fever of non-renal origin and corresponded to the findings of
pyelonephritis
. It is suggested that fever per se is the most likely cause of the tubular
proteinuria
seen in acute
pyelonephritis
. In localizing an acute UTI characterization of the urinary protein profile seems to have no advantage over a carefully measured body temperature. The urinary excretion of alpha 1M,beta 2M and RBP were highly correlated, while urinary NAG activity was less correlated to these low-molecular weight proteins. Fibrin degradation product D (FDP-D) was detected in the urines in 60% of the patients with acute
pyelonephritis
and in one third of those with acute cystitis. The estimation of FDP in urine therefore seems to be of little value in the level diagnosis of UTI.

There are indications that there is an increased risk of chronic renal failure (CRF) in the Negroid race, yet few studies have been carried out in the native 'black' environment. A clinico-pathological study of 100 consecutive Nigerian subjects with CRF, seen over a 3-year period, is presented. Primary chronic glomerulonephritis (CGN) accounted for 50, accelerated hypertension for 25, and various aetiological entities for a further nine; these included, chronic
pyelonephritis
(two), diabetic nephropathy (two), calculous nephropathy (one), toxaemia of pregnancy (one), renal dysplasia (one), tuberculosis (one) and polycystic disease in the ninth subject. In 16 cases, no definitive aetiological diagnosis could be made. Combinations of the following features, protracted hypertension,
proteinuria
, significant analgesic intake and gouty arthritis, were observed. CGN and accelerated hypertension still remain the leading causes of CRF, while diseases such as diabetes mellitus and chronic
pyelonephritis
do not contribute significantly to CRF in Nigerians. Recognition of the early features and the causes of CRF would considerably reduce the prevalence of this condition.

A total of 40 children who suffered from acute or chronic
pyelonephritis
underwent immunological treatment with polypeptide drug tactivin. There was an evidence of clinical and laboratory improvement in 82.5 per cent of treated persons, first manifest in decreased
proteinuria
and normalized urinary sedimentation, and then in lower levels of bacteriuria due to the developing resistance to infectious agents. In 15 per cent of tactivin-treated children leukocyturia persisted though the disease progression was hindered. In the course of the treatment no side-effects were noted. In line with the stimulation of humoral immune response and activation of the complement system, tactivin administration evoked the competence of T-lymphocytes and potentiated the development of this link of immune system. As part of combined treatment the above preparation favourably affected the disease pathogenesis in children.

The medical history of 256 hypertensive and 263 normotensive pregnant women was analysed retrospectively. There was a negative correlation (P less than 0.01) between the maximal pretreatment diastolic blood pressure and the birth weight of newborns in the hypertensive group. The prevalence of a hypertensive family history,
pyelonephritis
,
proteinuria
, delivery by Caesarean section, fetal asphyxia during delivery and death of the newborn during delivery was significantly higher in the hypertensive group than in the normotensive one. The gestational age at delivery was shorter and the birth weight of the newborn was lower in the hypertensive women than in the normotensive women.
