Hi Trish
glad Stuart is free of the catheter I am sure he is too!
The dribbles and spurts are normal and tend to happen when there is any small exertion.. standing up, bending down. lifting, coughing, sneezing, hiccuping, reaching up etc. so just about any body movememnt or bodily function. It should all improve quite quicky initially. The important things now are to maintain super cleanliness to avoid any infection, exercises to strengthen muscle control and not trying to hold on to go for a wee, Gravity does play a part too so with less body movement, lying down etc. nights are often easier than days.
I wish Stuart a speedy recovery post op and for you both to have some patience with each other as this can be a frustrating time.
Best wishes
