| Popis: | Authors from Hong Kong evaluated the role of ultrasonographically measured bladder variables in assessing bladder dysfunction in children with UTI. In a relatively large study, they confirmed the finding that the bladder volume and wall thickness index is a sensitive method for diagnosing bladder dysfunction in children. OBJECTIVE To evaluate the role of bladder variables measured by ultrasonography (US) in assessing bladder dysfunction in children with urinary tract infections (UTIs). PATIENTS AND METHODS Children presenting with recurrent UTI (with or with no vesico-ureteric reflux) were prospectively recruited. At entry, each patient had US and both natural- filling (NFC) and conventional-filling (CFC) cystometry. Bladder volume and wall thickness index (BVWI) was calculated, and based on US studies and the bladder pattern on US, were classified as thick (BVWI 130) as previously reported. The criteria for diagnosing urodynamic patterns included normal, overactive and hypocontractile, as reported previously. The correlation between the US measured variables and urodynamic findings were then evaluated. Sixty-one children (38 boys and 23 girls; mean age 4.82 years, range 1–11) were selected for further evaluation. RESULTS Of the 61 children, 16 had a normal BVWI, 36 a ‘thick’ value and nine ‘thin’. When the BVWI was correlated with the urodynamic findings, 14 of 16 with a normal BVWI had a normal bladder pattern, whereas 92% of the patients with a BVWI of 130, six of nine had a hypocontractile pattern. The mean (sd) bladder capacity (on CFC) compared to that expected for age was significantly lower, at 56.7 (32.3)% in ‘thick’ bladders, vs children with normal and thin bladders, at 91.3 (23.8)% and 98.7 (31.8)%, respectively (P |
