Traditional modeling of partial bladder outlet obstruction in rodents is fraught with animal mortality. A denervation injury from dissection around the proximal urethra and bladder neck is also of major concern. We developed and evaluated a safe and reliable mid-urethral obstruction model, avoiding the shortcomings of the traditional model.

In the present protocol, a urethral stricture induction was developed in Wistar rats, followed by urethral reconstruction with a buccal mucosa graft. A retrograde urethrogram and laser Doppler assessment were performed, validating urethral reconstruction (after stricture formation) and graft placement.

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to...

Generating Urinary Tract Infection Model: A Technique to Administer Uropathogenic Bacteria in Mouse to Develop Urinary Tract Infection Model
0 Views •
2025
In this video, we describe the technique for the intravesical administration of uropathogenic bacteria to generate a urinary tract infection model in mice. This model can be used to understand the spread of uropathogenic bacterial infection within the urinary system and the mechanisms that determine UTI susceptibility.
FAQs
Its value comes from providing a defined route into the bladder, where researchers can instill test materials under controlled conditions. The material may then be retained or recovered, allowing investigators to relate exposure to treatment response or urinary tract effects. This controlled access helps reduce variation between experimental conditions and strengthens comparisons among treatment groups.
Careful advancement helps limit tissue trauma while the catheter reaches the bladder, and standardized positioning makes the procedure more consistent across animals or experimental groups. Consistency matters because differences in placement or handling could affect how materials enter, remain within, or leave the bladder. These controls support more reproducible dosing and interpretation of biological responses.
Retention allows an instilled drug, tumor cell suspension, imaging agent, or other test material to remain in contact with the lower urinary tract under defined experimental conditions. Recovery provides a way to collect material after exposure when the study requires it. Together, these options let researchers design experiments around exposure duration, material handling, and outcome measurement.
Reliability depends on consistent catheter advancement, controlled placement within the bladder, and standardized handling of the instilled material. Minimizing tissue trauma is also important because injury could complicate interpretation of urinary tract biology or treatment response. When these elements are kept consistent, researchers can better distinguish effects caused by the test material from variability introduced by the insertion process.
A study typically defines the material to be tested, advances the catheter carefully through the urethral opening into the bladder, and instills the material under specified conditions. Investigators then retain or recover it according to the experimental design and assess the planned response. Standardizing these stages helps maintain consistent exposure and improves comparison across study conditions.
In cancer research, the approach is useful for intravesical studies in bladder cancer models. Researchers can deliver drugs to evaluate treatment response, introduce tumor cells to study tumor development, or administer imaging agents and other test materials. Because exposure occurs through the lower urinary tract, the method supports investigations focused on bladder tumors and urinary tract biology.
