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.

Primary Outcome Measures:
  • Relative risk of presenting a febrile UTI [ Time Frame: 24 months ]

Secondary Outcome Measures:
  • Number of children with febrile UTIs in each group at two years [ Time Frame: 24 months ]
  • Evolution of compliance to antibioprophylaxis. [ Time Frame: 24 months ]
  • Evolution of the grade of reflux [ Time Frame: At diagnosis and at 3 months ]
  • Comparison of the number of children who will show deterioration of their DMSA scan between children who have had UTIs and those who have not. [ Time Frame: 24 months ]
  • number and type of adverse effects related to circumcision and antibiotic prophylaxis [ Time Frame: 24 months ]
  • Identification of the responsible bacteria [ Time Frame: 24 months ]

Estimated Enrollment: 90

Arms Assigned Interventions
Antibiotic prophylaxis alone
Children will be on antibioprophylaxis and will not have a circumcision.
Other: Antibiotic prophylaxis alone
Antibiotic prophylaxis alone
Experimental: Circumcision and antibiotic prophylaxis
Children will have a circumcision at the time of valve resection and will be on antibioprophylaxis
Procedure: Circumcision

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.
