Abstract: This invention is to enable exact localization and display of the part being examined in graphic form. When doing an endoscopic examination the exact location of the treatment or examining element can be determined in relation to anatomical landmarks. This is particularly useful in one of the Urodynamic tests called Urethral Pressure Profile. The pressure being measured along the urethra can be correlated exactly with visible anatomical landmarks. Visible landmarks is stressed because during surgery the operating surgeon relies on visible landmarks to decide how much tissue needs to be removed. The results can be displayed, analyzed, interpreted, stored and printed. The same can be done with any other organ.

Abstract: An endoscope is modified so it can be connected to a computer. Thus all the movements of the said endoscope is monitored and displayed on the computer screen in color graphic form. When surgery is performed using the said endoscope there are limits within which cutting away of the diseased tissue is safe. Surgery beyond these safe limits can cause dangerous consequences to the patient. These safe limits are preset. During surgery the position of the cutting element of the said endoscope is continuously monitored and displayed. When any of these limits are transgressed and the cutting current is about to be switched on then an alarm by the computer alerts the surgeon. Events occurring during surgery are recorded on the computer disc for future reference. The importance of this is exact and continuous monitoring of the cutting element and recording the surgery for future playback and study.
