ABSTRACT:
A new endocystotomy tool for suprapubic cystostomy has a rigid sound, said rigid sound having standard configuration such as a standard Van Buren urethral sound. Said rigid sound having a distal end, said distal end having a removable tip, said removable tip being rounded. A second embodiment of said new endocystotomy tool for suprapubic cystostomy has an extendable trocar slidably seated within the rigid sound. Said second embodiment of said new endocystotomy tool for suprapubic cystostomy having a proximate end thereof which is provided with an insufflation port and a spring loaded plunger, which spring loaded plunger activates said extendable trocar. Either a catheter, a sheath, or a cystoscope is passed inside the tip of the new endocystotomy tool and secured therein. Thus the catheter, sheath, or cystoscope easily slides through the abdominal wall and bladder, i.e., the diameter of the catheter, sheath, or the cystoscope being smaller than the diameter of the new endocystotomy tool.
