PURPOSE
Bladder volume evaluation is a crucial point during investigation of bladder dysfunctions in children. It is usualy done by
using bladder diary and evaluating MVV as a functional bladder capacity.
The aim of the study was to compare compatibility of MVV as a predictor of functional bladder capacity and bladder
volume evaluated during triplicate urine flow measurements with ultrasound evaluation of PVR as an alternative method
for evaluation of bladder capacity in different various well defined bladder disturbances.
MATERIAL AND METHODS
52 treatment naïve patients with bladder dysfunctions were diagnosed in our secondary center. Patient history, bladder
diary consisting of 14 days recording of bladder symptoms and 48h frequency/volume chart, and triplicate urine flow
measurement (Andromeda device) with post void residual evaluation with ultrasound was done. Type of bladder
dysfunction was evaluated in accordance with ICCS terminology. Normal bladder capacity was defined as 65-150% of
EBC for age.
RESULTS
After complex evaluation 26/52 patients were diagnosed with OAB, 11/52 with MNE, 13/52 with dysfunctional voiding
and 2/52 with enuresis risoria. Decreased bladder capacity was found in both evaluating methods in 22/52 cases.
Incompatibility in bladder volume evaluation defined as normal/abnormal bladder volume between frequency/volume
chart and urine flow measurement was found in 10/52 cases, 6/26(23%) OAB, 2/11(18%) MNE, 2/13,(15%) DV and
0/2 (0%) enuresis risoria.
CONCLUSIONS
1.
High concordance (80%) was found between both methods.
2.
Bladder diary is objective method of bladder capacity evaluation as well as triplicate urine flow measurements and may
be used interchangeably diagnosing different types of bladder dysfunctions.
