Summary
This study introduces a fluoroscopy-free technique for ureteral access sheath placement during endourologic procedures. This direct visual method safely reduces radiation exposure for patients and surgical teams.
Area of Science:
- Urology
- Endourology
- Surgical Techniques
Background:
- Endourologic procedures commonly rely on fluoroscopy, posing radiation risks.
- Minimizing radiation exposure is crucial for patient and surgical team safety.
Purpose of the Study:
- To present a novel technique for ureteral access sheath placement without fluoroscopy.
- To evaluate the safety and efficacy of direct visual endoscopic access sheath placement.
Main Methods:
- A semi-rigid ureteroscope was used to navigate the renal pelvis.
- The ureteral access sheath was placed over the ureteroscope under direct endoscopic vision, acting as a guide.
Main Results:
- Successful ureteral access sheath insertion was achieved in 88 of 106 procedures (83%).
- Mean insertion time was 19 seconds.
- The stone-free rate was 78.12%.
Conclusions:
- Ureteral access sheath placement can be safely performed using direct visual control with a semi-rigid ureteroscope.
- This technique eliminates radiation exposure during the procedure.
- It potentially leads to shorter operative times.

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
