Urinary infection after micturating cystography.

Out of 87 patients who underwent micturating cystourethrography (M.C.U.) 14 had infection at the time of the procedure, and infection later developed in 18 patients. The occurrence of post-M.C.U. infection was significantly influenced by whether the patient was on antibacterial treatment at the time of the procedure, but not by the sex of the patient, difficulty of catheterisation, or radiological abnormality. Hence, antibacterial prophylaxis should be given, and subsequent urine culture is mandatory.
