Cited by 3 •
2023
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.

Nerve-sparing Mid-urethral Obstruction (NeMO) in Female Small Rodents

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.

The ability to model urinary tract infections (UTI) is crucial in order to be able to understand bacterial pathogenesis and spawn the development of novel therapeutics. This work’s goal is to demonstrate mouse models of experimental UTI and catheter associated UTI that recapitulate and predict findings seen in humans.

This protocol first describes the surgical procedure of the permanent implantation of a urinary bladder catheter combined with external urethral sphincter electrodes, and second, the measurement of the function of the urinary bladder and external urethral sphincter in implanted awake animals.
FAQs
These symptoms result from mucosal irritation and the immune response triggered within affected urinary tissues. In bacterial or sexually transmitted infections, pathogen colonization stimulates inflammation, while chemical irritants and trauma can produce similar irritation without infection. Because several mechanisms can create overlapping symptoms, symptom patterns alone cannot reliably establish the underlying cause or guide treatment.
The principal distinction is the anatomical site involved: bladder inflammation tends to relate to urinary storage and emptying symptoms, whereas urethral inflammation may reflect colonization by sexually transmitted pathogens. This difference matters because urethritis may require pathogen-specific testing and attention to transmission, while evaluation of bladder involvement commonly emphasizes urinalysis and urine culture.
Chemical irritants and trauma can inflame the urinary tract even when bacteria are not responsible. Such noninfectious causes may resemble infection because irritation and immune activation can produce dysuria, frequency, urgency, or pelvic discomfort. Distinguishing these mechanisms from infectious disease prevents clinicians from relying on symptoms alone when selecting antimicrobial or supportive management.
Evaluation begins with a careful assessment of urinary and pelvic symptoms, followed by urinalysis to identify findings consistent with urinary inflammation. Urine culture can further assess bacterial involvement, while pathogen-specific testing is added when the clinical situation suggests urethritis or a sexually transmitted cause. This layered approach supports more accurate diagnosis than any single test alone.
Urine culture is useful when clinicians need to investigate bacterial involvement in urinary tract inflammation, whereas pathogen-specific testing helps identify particular causes of urethritis, including sexually transmitted pathogens. These tests refine the diagnosis when symptoms overlap or when infection must be distinguished from chemical irritation or trauma, allowing treatment and transmission-reduction strategies to match the suspected cause.
A confirmed or better-defined cause helps clinicians choose antimicrobial treatment when infection is responsible or supportive treatment when inflammation is noninfectious. Accurate diagnosis also helps prevent ascending infection by directing appropriate management early. When sexually transmitted pathogens are involved, identifying the cause additionally informs strategies to reduce transmission, while broader planning can address recurrence.
