CIRCumcision and Urinary Tract Infections in Boys With Posterior Urethral Valves

Not Applicable
Completed
Conditions
Posterior Urethral Valves
Interventions
Procedure: Circumcision
Other: Antibiotic prophylaxis alone
Registration Number
NCT01537601
Lead Sponsor
Centre Hospitalier Universitaire de la Réunion
Brief Summary

Children with posterior urethral valves (PUV) are at risk of presenting febrile urinary tract infections (UTI). Circumcision has been shown to decrease the number of febrile UTIs in healthy children. The effect of circumcision on the number of UTIs in boys with PUV has not yet been studied. Through a prospective randomised trial of children with posterior urethral valves the investigators wish to determine the effect of circumcision on the risk of presenting febrile UTIs. One group will be on antibiotic prophylaxis alone and the other will be on antibiotic prophylaxis plus circumcision performed at the time of valve resection. Both groups will be followed for two years, with clinical examination at 1, 3, 6, 12, 18 and 24 months. A DMSA scan will be performed at 1-2 and 24 months and biological renal function will also be monitored. The relative risk of presenting a febrile UTI in each group will be determined. Clinical, radiological and antenatal data concerning each child will be analysed. At 24 months follow-up, an "impact on family scale" survey (IOFS) will be proposed parents.

Detailed Description

After diagnosis of posterior urethral valves, children will be randomised either to antibioprophylaxis alone or antibioprophylaxis plus circumcision. Circumcision will be performed at the time of valve resection. Children will undergo a cystogram between 1 and 4 months to control valve resection. They will be followed for two years and the number of febrile UTIs in each group will be compared. The diagnosis of febrile UTI will be confirmed by urethral catheterisation or suprapubic aspiration. A DMSA scan will be performed at the beginning and end of the study to determine whether children who have presented febrile UTIs show deterioration of their DMSA as compared to those who did not present febrile UTIs.

At 24 months follow-up, "impact on family scale" survey (IOFS) whose main objective is to evaluate the impact of family support for a child with posterior urethral valves will be proposed parents.
