Summary
The 12/14F ureteral access sheath (UAS) is currently universal for flexible ureteroscopes (F-URSs). Future 10/12F UAS and smaller endoscopes may change compatibility for urologists.
Area of Science:
- Urology
- Medical Devices
- Endourology
Background:
- Ureteral access sheaths (UASs) and flexible ureteroscopes (F-URSs) are crucial for minimally invasive urologic procedures.
- Selecting compatible UAS-F-URS combinations is essential for procedural success and patient safety.
Purpose of the Study:
- To evaluate the compatibility of various commercially available UASs with different F-URSs.
- To provide urologists with data to select appropriate UAS-F-URS pairings for procedures.
Main Methods:
- Evaluated 21 UASs and 12 F-URSs.
- Assessed compatibility through frictionless insertion tests.
- Measurements were taken in French (F) units.
Main Results:
- All tested UAS-F-URS combinations were compatible.
- Frictionless insertion required a minimum internal UAS diameter of 12F.
- UAS length did not impact the compatibility outcome.
Conclusions:
- A correlation table was established between UAS and F-URS compatibility.
- The 12/14F UAS is currently the universal standard for all F-URSs.
- Newer 10/12F UAS sizes and miniaturized endoscopes are anticipated to alter compatibility standards.

2.2K
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

6.7K
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...

7.1K
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male...

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.
