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.

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.

Coronoid-Temporalis Pedicled Flap for Orbital Floor Defect Reconstruction
0 Views •
2025
This protocol presents a novel coronoid-temporalis pedicled flap (CTPF) technique for reconstructing small-to-medium orbital floor defects. CTPF avoids microvascular risks while maintaining biomechanical stability. Clinical cases demonstrate effective structural restoration, reduced complications, and preserved facial symmetry, offering a viable alternative to traditional grafts or alloplastic materials.
FAQs
Location and extent guide whether surgeons can remove the scarred segment and reconnect healthy urethral ends or must enlarge the narrowed channel. Limited disease may permit direct reconnection, whereas more extensive loss may require a tissue graft or flap. This planning links the repair method to the amount and distribution of damaged tissue.
A graft or flap provides additional tissue when the urethral channel cannot be adequately restored by simply joining healthy ends. The choice reflects the length or severity of the affected area and the need to widen the passage. Using added tissue can help reestablish a continuous channel when direct reconnection is unsuitable.
Temporary catheterization supports the reconstructed urethra while healing takes place. It provides a route for urine during the early recovery period and helps maintain the intended passage as repaired tissue stabilizes. Because catheterization is temporary, it functions as postoperative support rather than the definitive treatment for the underlying narrowing, injury, or abnormality.
Reestablishing a continuous urinary passage addresses the interruption or narrowing that can obstruct urine flow. As the channel is restored, patients may experience improved flow and reduced obstruction-related symptoms. The goal is not only to create an open passage but also to achieve durable functional recovery after the repaired tissue has healed.
The procedure begins by addressing the damaged or scarred section according to its location and extent. Surgeons may remove the affected tissue and reconnect healthy ends, or widen the channel with a tissue graft or flap. Temporary catheterization then supports the repair during healing, linking the operative reconstruction to early postoperative care.
Urethral stricture disease is a common indication, particularly when narrowing interferes with urinary passage. Reconstruction may also be considered after traumatic injury and for selected congenital or postoperative abnormalities. These conditions differ in origin, but each can leave the urethra narrowed, damaged, or absent enough to require restoration of its structure and function.
Clinical assessment focuses on whether the reconstructed passage remains continuous and supports urinary function. Relevant outcomes include improved urine flow, reduction of obstruction-related symptoms, and the durability of functional recovery over healing. These measures help indicate whether the selected repair has adequately addressed the underlying narrowing, injury, or structural abnormality.
