What is Bladder Outlet Obstruction Nomogram for Women with Lower Urinary Tract Symptomatology about?

The aim of our study was to construct a bladder outlet obstruction nomogram for women with lower urinary tract symptoms. A urodynamic database of 600 consecutive women was reviewed. Bladder outlet obstruction, utilizing strict diagnostic criteria, was diagnosed in 50 (8.3%) patients. A comparison of patient characteristics, uroflowmetry, and detrusor pressure-uroflow studies was carried out between the obstructed patients (mean age, 64.4 ± 17.6 years) and 50 age-matched unobstructed controls (mean age, 64.8 ± 10.7 years). Maximum flow rates were significantly higher in free uroflow studies (free Qmax) than in pressureflow studies (Qmax), in both obstructed (9.3 ± 3.7 versus 5.7 ± 3.6 mL/s, respectively. P ‫ס‬ 2.6 10 -6 ) and unobstructed (25.6 ± 11.2 versus 11.8 ± 5.9 mL/s, respectively. P ‫ס‬ 8.7 10 -12 ) patients. Comparison of detrusor pressure at maximum flow (pdet.Qmax) and maximum detrusor pressure during voiding (pdet.max) values did not reveal significant differences, in both obstructed (39.3 ± 18.4 versus 49.7 ± 25.5 cm H 2 O, respectively) and unobstructed (16.5 ± 8.4 versus 20.6 ± 9.2 cm H 2 O, respectively) patients. Further statistical analysis was carried out to const
