We examined changes in nocturnal urine production and bladder capacity in enuretic children during bell and pad treatment.
A total of 18 children 7 to 11 years old with severe nocturnal enuresis had nocturnal urine production measured for a 14-day baseline period, which included daytime voidings on weekends. Thereafter, a 6-week treatment with the bell and pad was initiated, and nocturnal urine production and bladder capacity were monitored.
Of 18 patients 10 became dry. Maximum daytime bladder capacities before treatment were fairly normal with no indication of treatment outcome. At the beginning of treatment maximum nocturnal bladder capacity was smaller than maximum daytime bladder capacity and during treatment it increased gradually. An increase in bladder volume during the enuretic episode was noted as well. No overall changes were found for nocturnal urine production.
Treatment with the bell and pad is associated with a significant increase in nocturnal bladder capacity, in children who became dry and in those who remained wet. This increase explains why after attaining dryness the children were able to sleep through the night instead of having nocturia.
我们研究了遗尿儿童在铃铛和尿垫治疗期间夜间尿量及膀胱容量的变化。
共有18名7至11岁的重度夜间遗尿儿童，在为期14天的基线期测量夜间尿量，其中包括周末的日间排尿量。此后，开始为期6周的铃铛和尿垫治疗，并监测夜间尿量和膀胱容量。
18例患者中有10例不再尿床。治疗前最大日间膀胱容量基本正常，无法预示治疗结果。治疗开始时，最大夜间膀胱容量小于最大日间膀胱容量，治疗期间逐渐增加。遗尿发作期间膀胱容量也有增加。夜间尿量未发现总体变化。
对于尿床儿童和未治愈儿童，铃铛和尿垫治疗与夜间膀胱容量显著增加有关。这种增加解释了尿床儿童治愈后能够整夜睡眠而不再夜尿的原因。
