This video demonstrates a technique for generating a primary culture of neurons and glia from a rat's urinary bladder. It outlines the steps involved in tissue preparation, enzymatic digestion to obtain single cells, and culturing the cells in a neuron-specific medium to establish a primary neuronal and glial culture.

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.

Approximately 3-8 million people in the United States suffer from interstitial cystitis/bladder pain syndrome (IC/BPS), a debilitating condition characterized in part by pelvic pain. In order to study nervous system contributions to the condition, a physiological model of urinary bladder pain is used in mice and rats.

Surgical stages of bladder augmentation are described using 3-D scaffolds in murine and rat models. To test the efficacy of biomaterial configurations for use in bladder augmentation, techniques for both awake and anesthetized cystometry are presented.
FAQs
Each modality generates contrast through a different physical signal: ultrasound detects reflected waves, magnetic resonance imaging measures magnetic resonance signals, X-ray methods assess attenuation, and optical systems detect emitted light. This distinction affects which bladder features can be visualized and helps researchers select an approach suited to anatomy, volume, wall structure, or functional monitoring.
Imaging can provide quantitative measurements of bladder capacity, volume, wall structure, and remodeling. Repeating these measurements in living rats allows investigators to compare changes within the same subject rather than relying only on separate tissue collections. The resulting time-dependent data can reveal progression or treatment-associated changes in urinary tract studies.
Longitudinal imaging permits repeated observation of the same animal during disease progression, tissue regeneration, biomaterial evaluation, or device testing. Because measurements can be collected in vivo over time, researchers can follow structural and functional changes while reducing the need for repeated tissue collection. This supports more direct assessment of evolving biological responses.
Selection depends on the information required and on the signal used to produce the image. A study focused on volume, wall structure, functional changes, or treatment response may favor different modalities because ultrasound, magnetic resonance, X-ray, and optical methods do not generate contrast in the same way. The experimental objective therefore determines the most appropriate approach.
A study first identifies the bladder feature or response to be measured, then selects an imaging approach capable of producing the relevant in vivo information. Researchers acquire images from laboratory rats and evaluate anatomy, volume, wall structure, or function across time. These measurements can then be compared during biomaterial, regeneration, disease-model, or device-performance experiments.
The technique supports research on urinary tract function, biomaterials, tissue regeneration, disease models, and implanted or evaluated device performance. Imaging provides noninvasive or minimally invasive measurements that can be linked to bladder capacity, remodeling, and treatment response. In this context, it helps connect engineered interventions with observable changes in living tissue.
