Intervertebral disc degeneration is a significant contributor to back pain and a leading cause of disability worldwide. Numerous animal models of intervertebral disc degeneration exist. We demonstrate an ovine model of intervertebral disc degeneration, utilizing a drill bit, which achieves a consistent disc injury and reproducible level of disc degeneration.

The zebrafish kidney is home to both renal and hematopoietic adult stem/progenitor cells, and represents an outstanding opportunity to study these cell types and their progeny in a vertebrate model organism. Here, we demonstrate a detailed dissection procedure that enables the researcher to identify and surgically remove the adult zebrafish kidney, which can be used for applications such as cell isolation, transplantation, and expression studies of kidney and/or blood cell populations.

FAQs
Following the natural tissue planes helps separate structures behind the peritoneal cavity while limiting unnecessary tissue disruption. This approach provides access to the posterior abdominal wall and helps the operator recognize the expected relationships among the kidneys, adrenal glands, ureters, major vessels, and lymph nodes. Preserving these planes supports more deliberate operative planning in a confined anatomical region.
Mobilizing the peritoneum creates access to retroperitoneal structures without treating the peritoneal cavity as the primary operative field. As the peritoneum is moved, the operator can expose and separate deeper structures along the posterior abdominal wall. This maneuver is important for reaching target anatomy while maintaining awareness of nearby urinary structures, vessels, nerves, and lymph nodes.
The relationships among the kidneys, adrenal glands, ureters, major vessels, lymph nodes, and posterior abdominal wall require careful attention. Critical vessels, nerves, and urinary structures may lie close to the intended dissection area, so identifying them before separation helps reduce the risk of tissue injury. Understanding these relationships also supports safe access to pathology in a limited space.
In anatomical education, the technique demonstrates how structures are arranged behind the peritoneal cavity and connected to the posterior abdominal wall. Learners can study the relative positions of the kidneys, adrenal glands, ureters, major vessels, and lymph nodes while observing the importance of tissue planes. This spatial understanding provides a foundation for interpreting operative anatomy and planning procedures.
The approach can support tumor removal, lymph-node assessment, adrenal surgery, renal surgery, and vascular repair. The specific target varies, but each application depends on exposing the relevant retroperitoneal structures and preserving nearby critical anatomy. Because the region contains several closely related organs and conduits, the technique helps clinicians address pathology while maintaining the anatomical relationships needed for operative control.
By clarifying tissue planes and the positions of vessels, nerves, urinary structures, and organs, retroperitoneal dissection helps clinicians anticipate the anatomy encountered during surgery. That knowledge can guide selection of an access strategy, identify structures requiring protection, and reduce avoidable tissue injury. It is particularly relevant when pathology occupies the confined retroperitoneal region or involves multiple neighboring structures.
