The financial cost of bedwetting management is often underestimated. A
study including 48 children aged 6 to 16 years was carried out in the
outpatient clinic in order to evaluate the cost of these disorders du
ring a 4 month-period. The diagnosis was the following: nocturnal enur
esis (n = 15), bladder instability (n = 22) and other voiding dysfunct
ion (n = 11). Our results showed that these expenses were quite import
ant. A relationship between the kind of voiding dysfunction and the su
bsequent expenses was observed: the more complex was the disorder, the
more expensive it was (average expenses = 1317 FF/year for nocturnal
enuresis, 2506 FF/year for bladder instability and 3174 FF/year for ot
her dysfunctions). Subsidiary expenses (transport, diapers and extrawa
shing) constituted an important part of the whole expenses: 46% in noc
turnal enuresis, 42% in bladder instability and 38% in other dysfuncti
ons.
