Abstract: 

PURPOSE: TO ESTABLISH NORMAL REFERENCE VALUES OF URINARY FLOW RATE IN CHILDREN BETWEEN 7 TO 14 YEARS OF AGE IN IRAN.
MATERIALS AND METHODS: EIGHT HUNDRED AND TWO UROFLOWMETRY STUDIES WERE PERFORMED ON CHILDREN BETWEEN THE AGES 7 AND 14, 527 OF WHICH (192 GIRLS AND 335 BOYS) WITH NO HISTORY OF A RENAL, UROLOGICAL, PSYCHOLOGICAL OR NEUROLOGICAL DISORDER WERE ANALYZED. THE DATA WAS COLLECTED FROM DIFFERENT SCHOOLS IN DIFFERENT AREAS OF TEHRAN. THE VOIDING VOLUME, AS WELL AS THE MAXIMUM AND AVERAGE URINARY FLOW RATES, WAS MEASURED.
RESULTS: THE MAXIMAL AND AVERAGE URINE FLOW RATE NOMOGRAMS WERE PLOTTED FOR BOTH GIRLS AND BOYS. THE RELATION BETWEEN MAXIMUM OR AVERAGE FLOW RATES AND VOIDING VOLUME WAS BEST FITTED BY A LOGARITHMIC FUNCTION. MEAN MAXIMUM URINE FLOW RATE WAS 19.9 (ML/SEC) FOR BOYS AND 23.5 (ML/SEC) FOR GIRLS WITH A MEAN VOIDED VOLUME OF 142 (ML) FOR BOYS AND 147 (ML) FOR GIRLS. FLOW RATES SHOWED A CLOSE ASSOCIATION WITH VOIDING VOLUME IN BOTH SEXES. THE MAXIMUM AND AVERAGE FLOW RATES WERE HIGHER IN GIRLS THAN IN BOYS, AND THEY SHOWED A SIGNIFICANT INCREASE IN FLOW RATES WITH INCREASING AGE, WHERE BOYS DID NOT.
THE MEAN MAXIMUM URINE FLOW RATES (19.9 ML/SEC FOR BOYS AND 23.5 ML/SEC FOR GIRLS) AND AVERAGE URINE FLOW RATES (8.1 ML/SEC FOR BOYS AND 8.8 FOR GIRLS) WERE FOUND TO BE HIGHER IN THIS STUDY THAN THE VALUES REPORTED IN WESTERN STUDIES.
CONCLUSIONS: NOMOGRAMS OF MAXIMAL AND AVERAGE FLOW RATES OF GIRLS AND BOYS ARE PRESENTED IN CENTILE FORM, WHICH CAN HELP THE PHYSICIAN TO EVALUATE THE RESPONSE TO MEDICAL OR SURGICAL TREATMENT AND BE USEFUL FOR THE SCREENING OF LOWER URINARY TRACT DISTURBANCES IN CHILDREN, FOR A WIDE RANGE OF VOIDED VOLUMES.
