Laparoscopic Right Radical Nephroureterectomy
Step by step
Urinary bladder approach
Introduce a thoroughly lubricated working sheath under direct vision of a cystoscope into the urethra, advancing it until the urinary bladder is reached.
Working sheath introduction
The working sheath can either be introduced under direct vision or blindly. The advantage of introducing it under direct vision is that anatomical landmarks can be inspected simultaneously. When introduced blindly, an obturator is inserted in the working sheath to aid the introduction.
