Abstract: 

OBJECTIVES: PRESSURE FLOW STUDIES ARE NOW ONE OF THE BEST METHODS OF QUANTITATIVELY ANALYZING VOIDING FUNCTION. AS WE NEED TO CATHETERIZE THE PATIENT FOR CYST METRIC EVALUATION AND THEN PERFORMING FLOWMETRY STUDY, EXISTING URETHRAL CATHETER MAY INTERFERE WITH FLOW METRIC FINDINGS, AND CAUSING SOME DEGREE OF OUTLET OBSTRUCTION. THIS STUDY WAS DESIGNED TO EVALUATE THE ROLE OF URETHRAL CATHETER IN THE RESULTS OF FLOWMETRY.
MATERIALS AND METHODS: DURING A CROSS OVER CLINICAL TRIAL, PATIENTS WHO REFERRED TO OUR URODYNAMIC DEPARTMENT AT CHILDREN MEDICAL CENTER FOR PFS WERE SELECTED. PFS WAS PERFORMED ONCE USING URETHRAL CATHETER AND THEN WITHOUT IT. VARIABLES SUCH AS VOIDING VOLUME, MAXIMUM FLOW RATE, MEAN FLOW RATE AND TIME TO MAXIMUM FLOW RATE WERE RECORDED IN EACH SESSION. ROLE OF URETHRAL CATHETER ON THESE PARAMETERS WAS EVALUATED USING DEPENDENT T TEST. P VALUE LESS THAN 0.05 WAS CONSIDERED SIGNIFICANT RESULTS: BETWEEN JUN 2002 TO MAY 2003, IN 97 CHILDREN WITH MEAN AGE OF 8.03
±3.1, PFS WERE PERFORMED. THERE WERE 30 (30.9%) BOYS AND 67 (69.1%) GIRLS. UNDER LYING PROBLEM WERE MOSTLY UTI (43.3%) AND VUR (39.2%). MAXIMUM FLOW RATE (23.2 VS.20.8), MEAN FLOW RATE (9.8 VS.9.1) AND TIME TO MAXIMUM FLOW RATE (10.9 VS.10.1) WERE NOT STATISTICALLY DIFFERENT IN TWO SESSION (P=0.27, P=0.2, P=0.53 RESPECTIVELY).
CONCLUSION: PFSS ARE NOW FREQUENTLY USED FOR EVALUATING URINARY TRACT FILLING AND EMPTYING ABILITY. USING URETHRAL CATHETER CANNOT INTERFERE WITH THE RESULTS OF FLOWMETRY AND REDUCE THE TIME OF PRESSURE FLOW STUDIES.
