    Description / Table of Contents: Zusammenfassung 62 Patienten (14 Knaben, 48 Mädchen), bei denen an insgesamt 85 Niereneinheiten ein vesico-renaler Reflux (Grad 2–4) erfolgreich operiert worden war, wurden im Durchschnitt 9,3 Jahre postoperativ auf das Auftreten von Harnwegsinfektionen (HWI) und von neuen Nierenparenchymnarben (NN) verfolgt. Bei den männlichen Patienten traten postoperativ bis auf einen Knaben keine HWI bzw. NN auf. Ähnliches galt auch für etwa 45% der Mädchen. Beide Gruppen von Patienten wiesen vor Operation hohe Refluxgrade auf. Bei den übrigen Mädchen, deren präoperative Reflux-Grade im Durchschnitt relativ niedrig lagen, traten jedoch postoperativ über Jahre noch HWI auf. NN entwickelten sich vorwiegend in dieser Zeit. Untersuchungen der Fähigkeit von Uroepithelzellen (UEZ), das Bakterienwachstum zu hemmen, zeigten, daß die UEZ dieser Patienten das Bakterienwachstum nicht supprimieren konnten. Somit entsprachen diese Mädchen bezüglich ihrer UEZ-Funktion Patientinnen mit asymptomatischer Bakteriurie. HWI und NN bei Reflux scheinen somit durch unterschiedliche Ursachen ausgelöst zu werden.
    Notes: Summary 62 patients (14 boys, 48 girls) representing 85 refluxive renal units (Grade 2–4) were investigated after successful operation for the development of further urinary tract infections (UTI) and renal scars (RS). The mean follow-up was 9.3 years. With the exception of one boy, none of the male patients developed any UTI or new RS. A similar result was obtained for about 45% of the girls. These two groups of patients presented with high-grade reflux before surgery. The remaining female patients (about 55%), however, presenting with lower-grade reflux before surgical treatment, developed further UTI as well as new RS despite surgical correction of their reflux. Investigations on the capacity of uroepithelial cells (UEC) to suppress bacterial growth revealed a deficient antibacterial effect of UEC in these patients. Such an UEC defect has also been shown in patients with asymptomatic bacteriuria. In conclusion, different reasons seem to be responsible for recurrent UTI and the development of RS in patients with reflux.

    Notes: Abstract Two siblings are reported with a unique association of nephrogenic diabetes insipidus, intracerebral calcifications, defective psychomotor development, dwarfism and peculiar facial appearance. The disorder is to be differentiated from similar disorders, notably the Cockayne syndrome.

    Notes: Abstract After primary bladder closure or urinary diversion, other factors apart from the reconstruction itself gain importance for individuals with the exstrophy-epispadias complex: social integration and, after reaching puberty, sexuality and fertility. Between 1968 and July 1994 115 patients with bladder exstrophy or incontinent epispadias underwent surgery at our institution. A total of 104 patients could be followed, 2 of whom died in the meantime. Of the remaining 102 patients 48 attend school, 4 are in college, 40 have completed or are currently undergoing vocational training, 3 are unemployed, 1 lives in a therapeutic centre and 6 are younger than 6 years of age. A total of 95% of the patients with continent urinary diversion are continent day and night, whereas only three of five patients with a sling plasty (incontinent epispadias) or with primary bladder closure followed by a Young-Dees procedure are continent. None of the patients showed deterioration of renal function. In 25 females the external genitalia were reconstructed. Fixation of the uterus was done in 13 to correct or prevent uterine prolapse. Of the 17 women older than 18 years of age with genital reconstruction, 16 are satisfied with the cosmetic result. All adults engage in sexual intercourse. Five women have delivered seven children by Caesarean section. Of the 35 male adults 32 underwent reconstruction of the external genitalia and 34 males achieve erection. One developed necrosis of the penis early in life following primary bladder closure performed at an outside hospital. Penile deviation was present in 11 of the 32 patients with genital reconstruction, which is distressing in only 2. Thirty patients are satisfied with the cosmetic result. After genital reconstruction 9 males developed epididymitis, necessitating two orchiectomies and three vasectomies. No patient with reconstruction of the external genitalia can ejaculate normally or has fathered children, whereas ejaculation was normal in the three men who did not undergo genital reconstruction and in two patients prior to post-pubertal reconstruction. Furthermore, two of these three men have fathered four children.

    Notes: Abstract The occurrence of a Wilms tumour in a 4-year-old girl with bilateral medullary sponge kidney, Beckwith-Wiedemann syndrome and congenital hemihypertrophy demonstrates the close relationship between these disorders. Another six cases from the literature with congenital hemihypertrophy and with medullary sponge kidney are discussed, two of them also developed intra-abdominal neoplasm.

    Notes: Abstract The effect of buccal epithelial cells (BEC) on bacterial growth was investigated in healthy subjects as well as in patients with recurrent urinary tract infections (UTI) and compared to the antibacterial capacity of uroepithelial cells (UEC) of the same individuals. Epithelial cells were obtained from the following groups: healthy female controls; females without further UTI after reflux operation; females with asymptomatic bacteriuria (ABU); females with further UTI despite successful reflux operation; and patients with meningomyelocele (MMC) and recurrent UTI due to significant residual urinary volume. Cocultivation of Escherichia coli with BEC as well as UEC from healthy females or patients with MMC resulted in significant suppression of bacterial growth. However, neither type of epithelial cell showed an antibacterial effect when they were obtained from patients with recurrent UTI in the absence of urological abnormalities (ABU patients; reflux-corrected patients with further UTI). From these results it is concluded that a generalised epithelial defence defect is one important pathogeneic factor for recurrent idiopathic UTI.

Furthermore, two of these three men have fathered four children. Conclusion Education, occupation and social development of patients with urinary diversion are uneventful. The cosmetic results achieved by genital reconstruction are satisfactory. In female patients, antefixation of the uterus should be performed before or together with an introitusplasty to prevent uterine prolapse. In male patients, however, surgery is performed at the expense of fertility. Detailed discussions with the patients and their parents should include not only the question of primary bladder closure versus urinary diversion, but also the pros and cons of correction of the external and – in females – the internal genitalia.
