Abstract
Purpose
To investigate the obstructive findings urodynamically in idiopathic detrusor overactivity and compare them (maximum flow rate ‘Q max’ detrusor pressure at maximum flow ‘PQ max’) with control group.
Materials and Methods
Cystometric evaluation and pressure flow studies were performed in 25 women with symptoms of idiopathic detrusor overactivity and control group comprised 40 women with anatomic incontinence without cystocele. Patients with pelvic floor prolapse, motor urgency and poor compliance were excluded from the study. Q max less than 15 ml/s and PQ max more than 40 cm water were accepted as obstruction.
Results
After cystometric evaluation, obstruction was found in 36% of patients with idiopathic detrusor overactivity and 15% in control group. The range of maximum flow rate and PQ max values were 2–43.7 ml/s (mean 14.47 ± 10.22) and 10–143 cm water (mean 58.97 ± 35.13) in idiopathic urge syndrome group. These values were 6.6–51.8 ml/s (mean 23.24 ± 12.43) and 9.7–61 cm water (mean 25.56 ± 12.43) respectively in control group. Q max and PQ max parameters were compared statistically between the two groups. Idiopathic detrusor overactivity group had lower mean Q max and higher mean PQ max values than control group (P < 0.001) Table 1.
Conclusion
Obstruction percentage was found to be more in idiopathic detrusor overactivity group than the control group.
