A urinary catheter assembly comprises a urinary catheter 1, wherein a drip stop valve is arranged at or in the vicinity of the distal, non-insertable part. In a first storage position, a tubular casing 2 is arranged to accommodate at least the insertable part of the urinary catheter, in which the tubular casing forms a sealed and closed compartment around the insertable part of the urinary catheter. In a second use position, an openable end of the tubular casing is opened, allowing the insertable part of the urinary catheter to be expelled out from the tubular casing. The casing, in a proximal part thereof, is provided with a narrowing section 21 forming a stop abutment for an enlarged distal part of the catheter. The tubular casing is further extendible between a relatively shorter length in the first storage position, and a relatively longer length in the second use position.
