Surgical techniques for endoscopic resection of bladder cancer.

Accompanying the advances in surgical techniques and new intravesical and systemic therapeutic agents for the treatment of individuals with bladder cancer has been the development of greatly improved instrumentation for viewing the interior of the urinary tract and removing neoplasms. Fiberoptic lenses can now be combined with a video system, which enables the urologist to examine the lower urinary tract, not only more easily but with greater magnification. Training is obviously accelerated with the use of video endoscopy. The system also provides the opportunity for documentation and transmittal of the operative findings using either still or motion photography. The endoscopic procedure should be carried out in an orderly fashion. Sufficient lenses and cautery loops must be available to visualize the entire lower urinary tract and to biopsy or resect any abnormality and ensure hemostasis. The urologist should work closely with the pathologist to obtain sufficient cytologic and pathologic material to be confident of the presence or absence of tumor.
