Urethrotomy
The urethrotomy or urethral slit is an endoscopic procedure for the treatment of urethral strictures . The urologist inserts the urethrotome into the urethra and makes a small incision in the area of the constriction. Two methods have become established: Otis urethrotomy and Sachse urethrotomy . There are also methods according to Jules-Germain-François Maisonneuve (1809–1894) and Jean Civiale , but these no longer play a role in practical urology.
Urethrotomy according to Otis
With this method, the urethra is incised “blindly”, which means that the surgeon cannot see the narrow point exactly. It is particularly suitable for strictures in the area of the external urethral meatus (external urethral exit) and distal pars pendulans urethrae (urethra in the penis). The instrument is inserted into the urethra. After opening, the roof-shaped knife is pulled back over the narrow area at 12 o'clock.
Sachse urethrotomy
If the stricture can be seen, a visual urethrotomy is always carried out with the Sachse instrument. The urethrotome is inserted under visual control. Then the knife in the instrument is extended and the urethra is incised at 12 o'clock. This process can be repeated several times. A urethral catheter is inserted to avoid complications.
