The significance of ultrasonography in diagnosing and follow-up of cystic cystitis in children

Objectives and study : Cystic cystitis is a separate form of urinary bladder inflammation, detected by cystoscopy in children with recurrent urinary infections. Cystoscopy is an invasive method, so the aim of this investigation was to determine the ultrasonographic characteristics of cystic cystitis and to assess the reliability of ultrasound in relation to cystoscopy in diagnosing cystic cystitis. Methods : The study included 115 girls with repeated urinary infections. Cystoscopy and ultrasonography was performed in all. According to the cystoscopic finding the subjects were divided into 4 groups. Lateral and posterior urinary bladder wall thickness was measured during ultrasonography. Volume of the liquid introduced into the bladder during cystoscopy and the ratio of this volume to the expected bladder capacity were determinated. Results : A statistically significant difference was found between all 4 groups, the method demonstrated a high degree of sensitivity (0.97) and specificity(0.91). Bladder wall thickness of 3.0 mm is presumed a borderline measure. In the group with normal cystoscopic finding the mean value of bladder wallthickness is 2.6 mm, in the group with less than 5 cysts it is 3.5 mm, in the group with 5 - 10 cysts it is 4.4 mm and in the group with more than 10 cysts the mean value is 4.8 mm. The probability that a positive test confirms the disease (LPR) is 10.95, and the ability for a negative test to confirm health (LNR) is 36, calculated for all groups. Percentile calculations were determined for wall thickness. Conclusions : Ultrasonography can replace endoscopy in diagnosis and follow-up of cystic cystitis in children, with at least 50% fullness of the urinary bladder as a prerequisite.
