Abstract: 

OBJECTIVES: RECURRENT UTI IS ONE OF THE MAJOR HEALTH PROBLEMS IN CHILDREN ESPECIALLY IN THE GIRLS. MANY OF THESE PATIENTS HAVE NOT ANY ANATOMICAL ABNORMALITIES PREDISPOSING THEM TO THIS PROBLEM, EXCEPT HIGH DETRESSOR PRESSURE AT VOIDING. THIS STUDY EVALUATES THE FREQUENCY OF HIGH DETRESSOR PRESSURE IN THIS GROUP AND THE EFFECT OF URETHRAL DILATATION ON REDUCING THIS PRESSURE IN CHILDREN. MATERIALS AND METHODS: DURING AN INTERVENTIONAL STUDY, GIRLS WITH HISTORY OF RECURRENT UTI WITHOUT ANY ANATOMICAL ABNORMALITY WERE EVALUATED WITH URODYNAMIC STUDY. IN PATIENT WITH HIGH VOIDING DETRESSOR PRESSURE, URETHRAL DILATATION WAS PERFORMED UNDER GENERAL ANESTHESIA. CHANGES IN URODYNAMIC FINDING WERE RECORDED THREE WEEKS LATER. THE EFFECT OF URETHRAL DILATATION ON URODYNAMIC PARAMETERS WAS CALCULATED USING DEPENDENT T TEST. P VALUE LESS THAN 0.05 WAS CONSIDERED SIGNIFICANT RESULTS: BETWEEN FEB.2003 TO MAY 2003, 14 GIRLS WITH MEAN AGE OF 7.1± 3.3 YEARS UNDERWENT UD STUDY. NONE OF THEM HAS ANY ANATOMICAL URINARY ABNORMALITIES. VOIDED VOLUME AND TIME TO QMAX WERE NOT DIFFERENT BEFORE AND AFTER URETHRAL DILATATION (P=0.93 AND P=0.81 RESPECTIVELY). QMAX AND QMEAN WERE HIGHER AFTER DILATATION (P=0.035, P=0.011 RESPECTIVELY), AND PVR AND PDET AT VOIDING WERE REDUCED SIGNIFICANTLY AFTER URETHRAL DILATATION (P=0.015 AND P=0.0003 RESPECTIVELY).
CONCLUSION: THIS STUDY SHOWS THAT HIGH PRESSURE VOIDING IS PREVALENT IN GIRLS WITH RECURRENT UTI. URETHRAL DILATATION MAY REDUCE THIS HIGH PRESSURE AND HAVE A ROLE IN PREVENTING RECURRENT INFECTION.
