In which examination we insert catheter to the Ureter:
- a- I.V.U.
- b- Retrograde urography.
- c- Ante grade urography.
- d- M.C.U.G.
- e- Non of the above.
The correct answer is: b. Retrograde urography.
Here's why:
- I.V.U. (Intravenous urography):
This examination involves injecting a contrast dye into the bloodstream and then taking X-rays to visualize the urinary tract. No catheter is inserted into the ureter.
- Retrograde urography:
This examination involves inserting a thin, flexible catheter through the urethra, bladder, and up into the ureter to inject contrast dye directly into the kidney and ureter. This allows for clear visualization of the ureter and any blockages or abnormalities.
- Antegrade urography:
This examination is similar to retrograde urography, but the catheter is inserted through a small incision in the skin directly into the renal pelvis, bypassing the ureter. It is less common than retrograde urography.
- M.C.U.G. (Micturition cysto-urethrogram):
This examination involves having the patient urinate while X-rays are taken to assess bladder function and potential issues with urine flow. It does not involve inserting a catheter into the ureter.
Therefore, only retrograde urography involves inserting a catheter directly into the ureter.
