Rigid cystoscopy can be performed under the same conditions, but is generally carried out under general anesthesia, particularly in male subjects, due to the pain caused by the probe. The sizes of the sheath of the rigid cystoscope are 17 French gauge (5.7 mm diameter), 19 Fr gauge (6.3 mm diameter), and 22 Fr gauge (7.3 mm diameter).
Ureteroscopy is an examination of the upper urinary tract, usually performed with a ureteroscope that is passed through the urethra and the bladder, and then directly into the ureter. [1]
At this time a rigid urethrotome or a flexible cystoscope/urethrotome combination will be inserted and guided to the face of the stricture and a small blade towards the tip of the instrument will be deployed using a trigger mechanism to cut the stricture at locations determined by the surgeon.
An intravenous drip is inserted and a person is given some sedation before a cystoscope, which is a flexible tube, is inserted into the bladder via the urethra. [5] 10 ml of contrast [14] is usually injected during cystoscopy, which is where a flexible tube is inserted into the bladder and to the lower part of the ureter. [5]
Many also undergo cystoscopy, wherein a flexible camera is threaded through the urethra and into the bladder to visually inspect for cancerous tissue. [6] Cystoscopy is most efficient at detecting papillary tumors (tumors with a finger-like shape that grow into the urine-holding part of the bladder); it is less efficient with small, low-lying ...
