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.

Esophageal Strictures-I: Introduction

2025
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous). Etiology The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN This experiment will use inductive coils to demonstrate the concept of inductor and inductance. Magnetic induction will be demonstrated using a rod magnet inserted into or extracted away from the core of a coil to induce a transient electromotive force (emf) voltage in the coil, measured by a voltmeter. This experiment will also demonstrate the mutual inductance between...

University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals ("The Guide") states that pain assessment and alleviation are integral components of the veterinary care of laboratory animals. The definition of anesthesia is the loss of feeling or sensation. It is a dynamic event involving changes in anesthetic depth with respect to an animal's metabolism, surgical stimulation, or variations in the...
FAQs
The initial thermal injury disrupts epithelial and subepithelial tissues in the targeted urethral segment. During healing, inflammation develops, collagen is deposited, and scar tissue contracts. These linked responses transform the original localized damage into progressively tighter narrowing, making the model useful for studying fibrosis mechanisms.
Reproducibility depends on keeping injury conditions standardized across experiments. The selected urethral segment and controlled delivery of electrical energy establish a defined site of tissue damage, while consistent conditions help generate comparable degrees of narrowing. This consistency allows investigators to distinguish treatment effects from variation between models.
The experimental narrowing reflects both the initial tissue damage and the subsequent repair response. Inflammation and collagen deposition develop during healing, and contraction of the resulting scar progressively reduces the lumen. Follow-up therefore captures the evolving fibrotic outcome rather than only the immediate effect of electrical injury.
A general workflow begins by selecting a urethral segment, applying electrical energy with an electrocautery instrument to create controlled thermal damage, and then allowing healing to produce the experimental lesion. Subsequent evaluation examines the resulting narrowing and its structural or functional consequences over time systematically.
Researchers can examine structural outcomes by assessing the extent of lumen reduction, while functional outcomes indicate how the induced narrowing affects urethral performance. Considering both domains is important because a model may show visible scar-related changes and functional consequences that are not represented by a single structural observation.
The model supports investigation of urethral fibrosis and comparison of interventions intended to address stricture disease. Researchers can use it to evaluate surgical, endoscopic, or pharmacological treatments, linking intervention effects to structural and functional outcomes. Its value increases when standardized injury conditions allow meaningful comparisons among studies.
