Cystometry is an efficient technique to measure bladder function of small animals in vivo. The bladder is continuously infused at rates controlled through an intravesical catheter, whereas the urethra is left free for micturition. This allows for repetitive filling and emptying of the bladder, while intravesical pressure and voided volume are recorded.

Implantation of cancer cells into the organ of origin can serve as a useful preclinical model to evaluate novel therapies. MB49 bladder carcinoma cells can be grown within the bladder following intravesical instillation. This protocol demonstrates catheterization of the mouse bladder for the purpose of tumor implantation and adenoviral delivery.

Intratracheal instillations deliver solutes directly into the lungs. This procedure targets the delivery of the instillate into the distal regions of the lung, and is therefore often incorporated in studies aimed at studying alveoli. We provide a detailed survival protocol for performing intratracheal instillations in mice.
FAQs
The bladder epithelium acts as a biological barrier between the delivered solution and underlying tissues. Its barrier properties affect how much of a therapeutic fluid contacts the target region and how long that exposure remains useful. This helps explain why intravesical delivery can concentrate treatment in the bladder while limiting the amount that reaches the rest of the body.
Dwell time determines how long the medication or therapeutic fluid remains in contact with the bladder lining. A prescribed interval allows the treatment to act locally before the solution is released through urination or drainage. Changing that interval could alter local exposure, so the timing is a planned part of the treatment rather than an incidental step.
Bladder instillation places the therapeutic solution at the organ where treatment is needed, whereas systemic delivery distributes treatment more broadly through the body. This localized strategy may reduce systemic exposure, while its effectiveness depends on contact between the solution and bladder tissues. The distinction illustrates how delivery route influences both treatment distribution and biological response.
The selected solution depends on the condition being managed and the intended biological effect. Clinicians may use intravesical treatment for interstitial cystitis or administer chemotherapy and immunotherapy for selected bladder cancers. These applications show that the same delivery route can support different treatment goals, with the solution determining the relevant therapeutic action and expected response.
The sequence begins by emptying the bladder, followed by catheter placement and introduction of the prescribed solution. The fluid remains in the bladder for the designated dwell time, then leaves through urination or drainage. Each stage supports localized exposure: emptying creates space, catheterization provides access, and timed release concludes the treatment interval.
The essential components are a catheter and the selected medication or therapeutic fluid. The catheter provides a route through which the solution enters the bladder, while the bladder itself serves as the localized treatment compartment during the dwell period. Release may occur through urination or drainage, depending on how the procedure is completed.
This technique connects urinary tract anatomy with epithelial barriers, localized exposure, and treatment response. Students can examine how access to an organ, retention time, and the properties of its lining influence therapy. It also provides a practical example of how delivery route can shape whether treatment remains concentrated at a target site or spreads systemically.
