In Reply.— Dr Altschul presents data on urinary tract infections during infancy and reports infection rates substantially lower than those we have previously reported.1,2 He then makes several conclusions based on these differences. His data indicate that the maximum infection rates would be 0.11% among girls and 0.02% and 0.12% among circumcised and uncircumcised boys, respectively. In contrast, from a population of 422,328 infants, we found the overall incidence of symptomatic urinary tract infection during the first year of life to be 0.57% in girls, 0.11% in circumcised boys, and 1.12% in uncircumcised boys.

We report the results of a two-part study examining the incidence of urinary tract infection during the first year of life. In the first part of the investigation, we reviewed the occurrence of urinary tract infection in a cohort of 3,924 infants born at our institution during a 4-year period. Infection developed in 16 infants (0.41%). The incidence of urinary tract infection in noncircumcised males was greater than the incidence in both female (P < .004) and circumcised male (P < .001) infants. In the second part of the study, we explored the frequency of urinary tract infection in all infants born in US Army hospitals, worldwide, over a 10-year period. There were 422,328 infants born in army facilities during this time period. Subsequent hospitalization for urinary tract infection occurred for 1,825 (0.43%) infants during the first year of life. Overall, there was no male preponderance for infections in early infancy compared with females. After an equivalent incidence during the first month of life, female infants had significantly more infections than did male infants (P < .001). However, noncircumcised male infants had a higher incidence of urinary tract infection than female infants (P < .001). Additionally, noncircumcised male infants had a tenfold greater incidence of infection than circumcised male infants (P < .001). There was a significant decrease in the circumcision frequency rate during the 10-year study period (from 85.4% to 73.9%, P < .001). As the number of circumcisions decreased, there was a concomitant increase in the overall number of urinary tract infections in males (P <.02). A reduced incidence of infection may be at least one medical benefit of routine neonatal circumcision.

Increased Susceptibility

In a recent report of 100 infants less than 8 months of age with urinary tract infection, it was noted that 95% of the male infants were not circumcised.1 The authors speculated from this observation that the uncircumcised male infant may have an increased susceptibility to urinary tract infection, but commented that the incidence of urinary tract infection in uncircumcised compared with circumcised infants was unknown. We report the results of a study documenting the incidence of unnary tract infection during the first year of life in a large cohort of infants born at our institution over an 18-month period and we also document the incidence of urinary tract infection in circumcised compared with uncircumcised male infants.

Abstract Background An association between bladder-bowel dysfunction (BBD) and urinary tract infection (UTI) is well-known. However, a question less explored is whether children with UTI early in life also have increased prevalence of BBD after they are toilet-trained. In this study, consecutively selected children with pyelonephritis during their first year of life were assessed for BBD at pre-school age. Methods Ninety-two children (51 boys) hospitalized due to pyelonephritis during their first year of life were assessed for BBD at median age 5.4 years. A validated BBD questionnaire, along with urine flow and residual volume measurements, was used for diagnosing BBD. During follow-up, the group was well-characterized regarding renal status, vesicoureteral reflux (VUR), and recurrent UTI. Results BBD was diagnosed in 35/92 (38%), of which the majority was sub-diagnosed with dysfunctional voiding (DV). There was a strong association between BBD and recurrent UTI during follow-up (p < 0.0001), but only a slight association with VUR status at presentation. Nevertheless, in the group with both BBD and VUR, recurrent UTI was four times higher (12/13, 92%) than in children who had neither VUR nor BBD (23%), (p = 0.0008). BBD was also associated with kidney damage (p = 0.017). Conclusion In children with pyelonephritis during the first year of life, 38% had BBD at pre-school age, regardless of whether they had VUR or not. The study shows an important association between BBD and recurrent UTI, so an assessment of BBD is therefore recommended for pre-school children with UTI, especially when they have history of pyelonephritis during infancy.

Various clinical and laboratory aspects in 15 kidney transplanted patients with urographic evidence of caliceal clubbing and adjacent parenchymal scarring in their native kidneys are reported. These lesions were found in 16 per cent of our series of kidney transplantations; below 35 years of age it was the second most frequent disease. In 9 of these patients severe vesicoureteral reflux had been demonstrated. In the remaining 6 patients reflux nephropathy was only a tentative diagnosis based on a striking similarity in the radiographs and in several clinical findings. Nine patients had symptoms (mainly related to urinary tract infection) from 1 to 17 years before diagnosis/urography, in 5 as early as the first year of life. Recurrent urinary tract infection and renal impairment were the most frequent disorders leading to the diagnosis. Replacement therapy was initiated at an average age of 32.7 years. Following renal transplantation urinary tract infection was documented in 37 per cent of patients whether the patient had been bilaterally nephrectomized or not.

SummaryStrains ofEscherichia coliisolated from adult females with symptomatic urinary tract infection were found to possess the following properties significantly more frequently than faecal strains: (i) high K-antigen titre; (ii) haemolysin; (iii) type 1 pili; (iv) mannose-resistant haemagglutination; (v) fermentation of dulcitol and salicin; (vi) O serotype 2, 6 and 75; (vii) H serotype 1.E. coliisolated from urine specimens containing significant numbers of antibody-coated bacteria were richer in these seven properties than strains from urines without detectable antibody-coated bacteria.The O and H serotypes ofE. coliobtained from patients with urinary tract infection in two New Zealand cities were compared with those reported in the world literature and found to be similar.
