Abstract


Background: The lower urinary tract dysfunction (LUTD) has high incidence in children with ano- rectal malformation (ARM) which if left untreated leads to upper tract damage.

Aim: To determine role of uroflowmetry in early diagnosis of LUTD in children with ARM.

Methods: This prospective study included twenty consecutive patients of ARM and every patient underwent uroflowmetry at-least 6 weeks after definitive procedure.

Results: The mean age of patients was 3.015±0.86 years. Of the twenty patients, there were 12 (60%) males and 8 (40%) females; 11 (55%) were high ARM, 4 (20%) were intermediate and 5(25%) were low ARM. Lower urinary tract symptoms (LUTS) was present in 8/20 (40%) patients but uroflowmetric abnormalities were present in 11/20 (55%) patients. Forty five percent (5/11) patients with abnormal uroflowmetry were asymptomatic and 25% (2/8) symptomatic patients had normal uroflowmetry. The incidence of uroflowmetric abnormalities was significantly higher in patients with spinal anomalies (p=0.03; χ2=4.1) and those with high ARM (p=0.004; χ2=8.1).

Conclusion: Uroflowmetry is a noninvasive method that may help in early detection of neurovesical dysfunction in asymptomatic children and subsequent cystometric analysis in patients with uroflowmetric abnormalities can be done for early definitive diagnosis and prevention of upper urinary tract damage.
