Among 1050 consecutive renal transplants (Rtx) performed in Heidelberg since 1967 we have gained experience with 163 children and adolescents under the age of 16, receiving a Rtx since 1969. 30% of these were terminally renal insufficient due to congenital obstructive uropathy, mainly infravesical obstruction and/or reflux nephropathy. A special diagnostic work-up (flow chart) for evaluating and eliminating potential pre- and posttransplant risk factors consisted of noninvasive screening methods (ultrasonography and uroflow) followed step by step by more invasive imaging procedures (MR, MCU) and finally invasive methods of evaluating upper urinary tract and voiding disorders (complete urodynamic work-up). We emphasize the preservation or rehabilitation of urinary bladder function, eradication of significant UTI and pre-Rtx surgical treatment of otherwise hard to handle nephrogenic hypertension. Unnecessary psychologically and somatically traumatizing pretransplant diagnostic and therapeutic procedures can be avoided in pediatric non-obstructive nephropathy patients.

During a 15-year period 29 patients were treated for unilateral multicystic kidney. The diagnosis was obtained from antenatal ultrasonography in 17 cases, investigation of an abdominal mass at routine palpation in 10, UTI investigation in 1 and uraemia investigation in 1. Eleven patients had associated malformations. Further investigations included ultrasonography, intravenous pyelography, micturition uretrocystography and in a few cases computed tomography and Dimercapto-succinic acid (DMSA) scan. Percutaneous pyelography was performed in 9 cases. Twenty-six children were operated on and 3 were not operated, of which 1 with severe cardiac malformations, died. The age at operation was under 6 months in 14 cases and between 6 and 12 months in 8. Four children developed hypertension preoperatively but the hypertension disappeared within 1 week postoperatively in all cases. The indication for surgery in unilateral multicystic kidney seems to be clear if the patient is symptomatic. In the asymptomatic patient, the complications of a remaining multicystic kidney like hypertension, malignancy, infection and pain suggest a surgical approach at around 6 months of age.

The highest figure for first-time UTI is found in infants below one year of age. These early infections are often pyelonephritic in character, but they are easily overlooked because symptoms are unspecific, high fever and failure to thrive being the most important. It has been shown that delay in start of treatment increases the risk of the child developing pyelonephritic scarring. There is reason to believe that undetected and therefore untreated attacks of pyelonephritis may be associated with renal scarring revealed later in life. This type of renal damage is associated with development of hypertension in about 10 per cent of children and it accounts for around 20 per cent of the children entered into dialysis and transplant programs. Prevention of such long-term problems would be of great value and pyelonephritic scarring is a potentially preventable disease. The majority of infants and young children with UTI are probably managed at the primary care level. It is therefore essential that general practitioners are well informed about the epidemiology of UTI in infancy and childhood and that adequate diagnostic facilities are provided. For example, suprapubic aspiration to obtain uncontaminated urine is a technique that may well be used in an outpatient setting, and dipslide cultures are accurate and inexpensive. In addition to young age, vesicoureteric reflux and repeated attacks of pyelonephritis are risk factors associated with development of renal scarring. Therefore, diagnostic imaging to detect children with anomalies within the urinary tract are especially important in the very young. Furthermore, long-term supervision should be provided and the parents advised to consult the doctor when there is suspicion of a new infection to avoid delay in treatment. There is no reason to perform general screening for bacteriuria in healthy infants. Although bacteriuria may be found in 1 to 2 per cent, asymptomatic children have a very high rate of spontaneous clearing of the bacteriuria and they seem to constitute a low-risk group. Instead, frequent culturing of urine from febrile infants would be much more important.

Fifty-eight patients were treated with cefotaxime (CTX, Claforan) intravenously. Almost all patients (54 patients) had underlying diseases that were 16 cases of diabetes mellitus, 10 cases of respiratory diseases, 8 cases of cerebral vascular disturbance, 6 cases of renal diseases and blood diseases, 5 cases of carcinoma and hypertension, 4 cases of cholelithiasis, 3 cases of heart diseases and 7 cases of other diseases. The clinical efficacy of CTX in 34 cases of RTI, 11 cases of UTI, 8 cases of BTI and 5 cases of other infection was excellent in 11 cases, good in 27 cases, fair in 12 cases, poor in 4 cases and unclear in 4 cases. The over all clinical effectiveness was 70.4%. No adverse reaction was observed except for 2 cases (general fatigue in 1 case and eruption and itching in another). These results obtained should support the usefulness of CTX.

The performance of 11 medical care systems of varying size and payment mechanisms (consisting of six government owned and operated Indian Health Service units, three fee-for-service private practices and two HMOs) was studied. Performance was defined as the percentage of consumers in need of care who received adequate care according to predetermined standards for the process of care for various functions (i.e., prevention, screening, treatment, follow-up) and various health conditions (i.e., prenatal and infant care, hypertension, anemia, UTI). Size was found to have a strong negative relationship to the quality of treatment and follow-up care, but payment mechanism did not show such a relationship. Neither size nor payment mechanism was significantly related to prevention performance. In screening, the results depended on the health condition: size was inversely related to performance of screening for hypertension; HMOs performed significantly better in screening for prenatal anemia; and neither size nor payment mechanism was related to performance of screening for infant anemia.

In a research project undertaken to describe the content of adult primary care, episodes of illness for six common primary care conditions were analyzed: URI (upper respiratory infection, UTI (urinary tract infection), HYP (hypertension), AP (abdominal pain), CP (chest pain), and PE (physical examination). Data from the Kaiser-Permanente Medical Care Program-Oregon Region were used in the project. Episode of the six conditions studied tended to be of brief duration; at least half of the episodes of each condition except hypertension involved only a single medical visit. The physical examination episodes typically involved both laboratory and radiology services, but these services were less frequently used for the other five conditions. Few episodes involved a referral to a consultant physician, the use of sophisticated ancillary procedures, repeat tests, or a hospitalization. If patients had been billed for the episode-related care involved in treating each episode, the average charge incurred (in 1980 dollars) would have bee: URI $38.67, UTI and HY $52.27 each, AP $66.59, CP $46.54, and PE $91.65, excluding the costs of pharmaceuticals. Ancillary services accounted for one-third or more of the costs for each type of episode except URI. The results suggest that cost savings in primary care are likely to depend less on the control of sophisticated medical technology than on efficiently meeting patient-initiated demands for care and on influencing physician-generated ordering of simple ancillary procedures. The results also suggest the utility of analyzing the distinctive demands on the medical care system that are generated by diverse primary care conditions.

Renal ptosis is the caudal acquired displacement of one or both of the kidneys, with different degree and etiology, considered as a urological pathology because of its urodynamic changes and, in the last years, almost completely neglected. The aim of the work is to research a parenchymal involvement, through a close examination of our outpatient record of cases, compared with data from the literature about renal ptosis. The literature reports the largest incidence in females; in our record of cases, instead, the incidence is nearly the same. Second degree ptosis is the most frequent, but, in females, bilateral ptosis is prevalent (77%). We agree with the literature about urinary symptoms; actually, the most of the patients shows urinary colics or lumbar pain. We also noticed UTI (62%), urinary lithiasis (26%) and pyelocalyceal ectasia (46%). A lot of patients suffer from microscopic haematuria (77%) and, in 12%, we noticed gross haematuria. Hypertension affects about half of the patients (46%) and proteinuria too (42%). Echography highlights a reduced cortex (12%), cysts (14%) and other changes (8%). GFR is decreased in 30% of cases, to a different degree. The patients show different changes, according to their age. In conclusion, considering that the incidence and the anatomic and functional changes are remarkable, we think it opportune to take renal ptosis into account as a cause of chronic renal damage, also because it is included among the causes of obstructive nephrophaty, which according to some researches, can cause severe glomerular and tubular-intestinal changes, triggered off by a short urinary stasis and evident in the controlateral kidney too.

This study was performed to evaluate prognostic factors in ADPKD progression to ERSF. Previously reported negative factors (male gender, age, hypertension, palpable kidneys and UTI) as well as the extra-renal presence of cysts and proteinuria, were analysed in a group of 45 ADPKD patients (Male/Female, 25/20; Age = 40.1 +/- 19.7 yrs, range 21-69). Palpable kidneys were associated with higher serum creatinine values (955 +/- 689 vs 743 +/- 504 umol/l, p < 0.001) but not with a greater prevalence of renal failure. Renal failure (100% vs 60%), higher creatinine values (981 +/- 495 vs 778 +/- 654 umol/l) and hypertension (50% vs 18%) were related to a higher prevalence of extra-renal cysts (p < 0.05). Older patients (> 40 years) had a greater prevalence of renal failure (96% vs 32%, p < 0.001). Also, subjects with palpable kidneys, and those with extra-renal cysts, were significantly older (52.8 +/- 10.3 vs 30.5 +/- 20.6 yrs, p < 0.025; and 42.1 +/- 21.9 vs 38.1 +/- 18.2 yrs, p < 0.025). Patients with renal failure and those with extra-renal cysts had a greater prevalence of proteinuria (65% vs 0%, p < 0.001; and 100% vs 24%, p < 0.001). No correlation was seen for male gender, hypertension or UTI with any known complications of ADPKD. The extrarenal presence of cysts, older age, proteinuria and palpable kidneys were associated with a worse renal outcome, but for this Romanian population we can't confirm previous reports suggesting a role for male gender and early onset of disease.

The long-term adverse consequences of UTI in childhood are hypertension, impaired renal function, end-stage renal disease, and complications during pregnancy. These adverse effects of UTIs are a result of renal parenchymal damage. Currently, these complications are unusual among patients in industrialized countries, unless kidney damage is present at birth. VUR, the most common abnormality encountered in infants and young children with UTIs, is not a diagnostic entity, but reflects a spectrum of underlying conditions. There may be nonobstructive VUR with no other urinary tract abnormality. VUR may be associated with voiding dysfunction and frequent UTIs. It may be present with bladder outlet obstruction, hydronephrosis, and intrauterine renal damage. Children with intrauterine renal damage are those most likely to develop hypertension and those at greatest risk for progression to end-stage renal disease. Acquired renal injury as a cause of adverse long-term consequences due to UTI is much less common than it was early in this century, probably as a result of improved health care.

One hundred and thirteen pregnancies in 73 women who received a renal transplant were studied. The duration between the transplant operation and the conception averaged 19.9 months with a range of I month to 72 months. The mean age was 28 years. The majority (50 recipients had one pregnancy each, but two women had 5 children each and one had seven children). Only 12 (11.5%) out of the 113 pregnancies ended up with spontaneous abortions. The maternal medical problems encountered were reversible rejection in 11%, hypertension in 43%, UTI in 17% and gestational diabetes in 21%. It was noted that there was high incidence of preterm delivery in 64% of the pregnancies Caesarian section was required in 72% % of the cases. In conclusion we observed a high prevalence of successful pregnancies with no adverse effect on the allograft function and excellent fetal outcome (which is described in a separate paper focusing on the fetal outcome).
