Does digital rectal examination affect uroflowmetry measurements?

To determine whether digital rectal examination (DRE) would affect uroflowmetry parameters and whether these findings were not due to the circaidan changes. A total of 79 male patients (59 in study and 20 in control group) were included in this study. First uroflowmetry was done at 10:00 am just before the genitourinary physical examination in the study group. Second and third uroflowmetry was performed at the 6th and 24th hour after the first uroflowmetry. The same uroflowmetry tests were done in a control group without DRE. Voided volume and maximum and average flow rate parameters of uroflowmetry were interpreted in our study. The relationship among first, second, and third uroflowmetry parameters were determined in the study and control groups. There were statistically no difference between the mean first, or 6th- or 24th-hour uroflowmetry parameters of the study and control groups (P > 0.05). We could not find any effect of DRE on uroflowmetry parameters. Studies in a larger patient series would be appropriate for recommending DRE before or after uroflowmetry test.

Urine Flow in Childhood: A Study of Flow Chart Parameters Based on 1,361 Uroflowmetry Tests

We attempted to analyze the parameters of the urine flow chart in children. We evaluated 1,361 uroflowmetry tests of healthy boys and girls, analyzed voided volume in relation to age and body surface area, and made a descriptive study of flow chart parameters. Analysis of variance was used for comparative study of these parameters in sex, age and body surface area groups. Mean values of maximum and average flow increased with voided volume, patient age and body surface, and they were higher in girls. However, mean values of flow time and time to maximum flow were higher in boys. Flow time increased with volume, and decreased with age and body surface, although time to maximum flow increased slightly with volume and did not change with age in boys or girls. Generally, we noted significant differences in maximum and average flow, and flow time and time to maximum flow in the different age groups and in both sexes. Regarding flow curve shape, a normal flow pattern (bell-shaped curve) was noted in more than 90% of cases. The plateau curve was apparent in 5.2 and 0.7% of boys and girls, respectively.

Computerized automatic responses of uroflowmetry tests

We developed a procedure to construct automatic responses of uroflowmetry tests based on data of patient's sex and age, voided volume, micturition time, high flow rate and shape of curve. The response is constructed by comparison of recorded data of actual test with expected values. The procedure works correctly in most cases, rarely a non-automatic response is required.
