A urinary catheter assembly comprises a urinary catheter (1) comprising a catheter shaft (1) and a non-insertable rearward part (2), wherein a lumen extends between a drainage opening at or in the vicinity of the insertion end of the catheter shaft and a discharge outlet (23) in the rearward part. Two arms (3) are rotatably connected to the rearward part, wherein the arms are rotatable between a first, storage position, in which the arms are aligned with each other and overlying the catheter shaft, and a second, use position, in which the arms are arranged aligned with each other in a different position, not overlying the catheter shaft.
