UroToday.com - This study by Dr. Erim Erdem, et al. from Turkey evaluated the reliability of bladder perception in children during cystometry, comparing it with the same measure in adults. A total of 30 children were included in this study, and the mean average of the patients was 11 years. There were two phases to the study. In the first phase, a catheter was fixed to the skin without introducing it through urethra. After the children were told that the test had begun, they were asked to report any sensations. In the second phase, an 8F urodynamics catheter had been introduced, but nothing was infused after a regular filling cystometry was performed.

Of the 30 children, four were excluded because of sensation defects in the cystometric evaluation. In the first phase, none of the children reported any first sensation, first desire, normal desire, or strong desire. In the second phase, three of the children reported a first sensation, and two reported a first desire. When the overall cystometry was performed with filling, all the 26 children reported sensations. The first sensation/normal desire percentage was 41%, and the first desire/normal desire percentage was 52%.

These children were compared to a previous study, reported by the same group, that found an important percentage of adults perceived false sensations in the placebo phases. The children in this study had no significant perceptions in the placebo phases. It appears that the sensations reported by children during urodynamics studies can be more reliable than those reported by adults.

This was a very interesting finding since it is perceived that urodynamic studies in children are quite difficult and they have a heightened sensation. This study suggests that their sensations are not heightened, but actually are more accurate.
