Abstract: The invention relates to a surgical drape suited for use in urethra surgical procedures. The drape is used in combination with a surgical sheet used for covering the torso and legs of the patient, with the patient's legs placed in a raised divergent attitude while the surgeon operates therebetween. The surgical drape is mainly characterized in that it has a substantially triangular shape and in that fastenings are provided at the corners of the triangle, these fastenings preferably having the form of a double-sided adhesive tape or coatings of bonding agent or pressure-sensitive adhesive substances. Those fastenings provided at the base corners of the triangle are intended to be secured to the surgical sheet in the vicinity of the lower legs or feet of the patient, and the fastening at the other corner at the site of the operation, so that the surgical drape hangs from its three corners in the shape of a bowl.
