Association of Voiding Dysfunction with Functional Constipation.

To identify the frequency of voiding dysfunction in patients with functional constipation, dysfunctional voiding soring system (DVSS) was surveyed in 85 patients with functional constipation. Urinalysis, culture and renal ultrasound were performed in all cases. If the child had urinary tract infection, voiding cystourethrography and DMSA scan were performed. Fifty four patients (63.5%) out of 85 had voiding dysfunction (DVSS score above 6 in females and above 9 in males) compared to 28 out of 280 normal children (10%) in control group (P<0.001). Voiding dysfunction symptoms should be examined carefully in patients with functional constipation.
