[Uroflowmetry and flow pressure study parameters in urogynecology patients].
OBJECTIVE
The purpose was to evaluate urine flow rates in an urodynamic study (US) of patients with symptoms of lower urinary tract dysfunction and to record effects of final urodynamic diagnosis and age on these variables.


METHODS
Retrospective analysis of 205 women who had undergone urogynecological investigation. Patients were divided into three age groups: A (< 45 years); B (45 - 60 years) and C (> 60 years). Comportment of urine flow rates and opening detrusor pressure with increasing age were studied and resulting charts recorded. Comparison of maximum and average urine flow rates, opening detrusor pressure and detrusor pressure at the maximal flow according to final urodynamic diagnostic were also made.


RESULTS
There was a decline of urine flow rates with increase of age, which was more significant between groups A X C and B X C. There was also a decline in opening detrusor pressure with aging, which was significant between groups A X C. When analyzing opening detrusor pressure according to final urodynamic diagnosis, a significant decline of this variable was observed in patients with urinary stress incontinence and intrinsic sphincter deficiency in relation to those who were asymptomatic.


CONCLUSIONS
Urine flow rates decreased with age. Women with urinary stress incontinence and intrinsic sphincter deficiency void at a lower detrusor pressure.
