Abstract

Two boys, aged 11 and 13, had involuntary, unstoppable, and complete emptying of the bladder on laughter. In one the wetting occurred only when standing and in company, but in the other occurred regardless of posture or company. One boy had a strong family history of wetting including a grandmother who had giggle micturition as a teenager. The symptoms had been present for between 1 and 2 years. However, unlike cases previously reported, each boy was cured--one within 6 weeks and the other within 6 months. It is not clear how much of the success was due to the general sympathetic and confidence-building measures used, advice about posture, or to the drug propantheline.
