A smooth blunt tip tubular structure in a form of a sound or a catheter and a pressure producing and regulating system. The sound or the catheter has a smooth blunt end on one end and a non blunted end on the opposite end. There is a lumen extending from one end to the opposite end. There is a furrow running circumferentially around the blunt end of the sound or the catheter. The furrow lies on the side wall within two centimer from the blunt end tip of the sound or the catheter. There are multiple openings on the floor of the furrow. The openings within the furrow communicate with the lumen of the sound or the catheter. The pressure producing end regulating system is in fluid communication with the lumen. The side walls of the furrow elevate above the surface of the sound or the catheter forming ridges. There are six grooves equally distanced from each other between the furrow and the tip of the sound or the catheter. With the entire system in operative condition, the tip of the sound or the catheter is able to carry by suction, the transected segment of membranous urethra to the pelvis for it to be anastomosed to the bladder neck at the time of radical retropubic prostatectomy.
