The benefit of performing ultrasonography and scintigraphy in the acute phase or cystourethrography is minimal. Our findings support (1) technetium-99m-dimercaptosuccinic acid scintigraphy 6 months after infection to detect scarring that may be related to long-term hypertension, proteinuria, and renal function impairment (although the degree of scarring was generally minor and did not impair renal function) and (2) continued surveillance to identify recurrent urinary tract infections that may warrant further investigation.

Early treatment of acute pyelonephritis in infants and young children had no significant effect on the incidence of subsequent renal scarring. Furthermore, there was no significant difference in the rate of scarring after acute pyelonephritis when infants and young children were compared with older children.

Background and objective: Bronchopulmonary dysplasia (BPD) is the most common chronic lung disease of infancy in the developed countries. Outcomes for BPD patients have traditionally been assessed using physiological parameters such as lung function, and no data are available on the health-related quality of life (HRQOL) for adolescents with BPD. The aim of this study was to assess HRQOL in adolescents with BPD, in comparison with age-matched and sex-matched control groups of healthy volunteers and asthmatic subjects. Methods: We enrolled 27 BPD patients (age range 11-19 years), 27 asthmatic patients and 27 healthy controls. HRQOL was assessed by the Short Form 36 (SF-36) questionnaire. Lung function was assessed by spirometry. Results: The BPD group did not differ significantly from the healthy controls in any scale or dimension of the SF-36 (the BPD group's summary scores were as follows: physical component summary mean 55.6 + 4.98 and mental component summary 51.8 + 7.75 vs 55.8 + 6.25 and 49.2 + 9.45 for the healthy control group, P > 0.5 and P = 0.26, respectively). Asthmatic adolescents scored lower than those of both healthy controls and patients with BPD in several SF-36 dimensions despite adolescents with BPD having lower lung function. No correlation emerged between lung function and HRQOL in BPD subjects. Conclusion: Despite their impaired lung function, BPD patients have an HRQOL comparable with healthy peers and better than asthmatic patients. We did not find any association between HRQOL and lung function parameters.
