The murine model of irreversible unilateral ureteric obstruction (UUO) is presented together with the model of reversible UUO in which the ureteric obstruction is relieved by anastomosis of the severed ureter into the bladder. These models enable the study of renal inflammation and scarring as well as tissue remodeling.

Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.

Among abdominal solid organ transplantation, pancreatic grafts are prone to develop severe ischemia reperfusion injury-associated graft damage, leading eventually to early graft loss. This protocol describes a model of murine pancreas transplantation using a non-suture cuff technique, ideally suited for analyzing these early, deleterious damages.

However, there are many factors that can complicate placement of a peripheral intravenous cannula (PIV), and it is extremely common for PIV attempts to fail. PIV placement may be technically challenging in small...
FAQs
Preserving the ureter’s blood supply supports the tissue while it is mobilized and joined to the receiving structure. Excessive disruption could compromise the reconstructed connection, making accurate alignment and durable healing more difficult. For this reason, mobilization must balance adequate movement with protection of the ureter’s vascular support, particularly when establishing a reliable urinary passage.
A submucosal pathway places the ureter within or beneath the receiving tissue before it exits into the urinary tract. This arrangement can create a longer, tissue-supported route that limits backward urine flow toward the ureter. Its relevance is greatest when reconstruction must provide both drainage into the receiving structure and protection against reflux.
Accurate alignment, a tension-free connection, and preservation of an open lumen are central technical factors. The cuff must be positioned so the joined tissues meet securely without narrowing the urinary passage. Careful suturing also supports a sealed connection, helping reduce leakage while maintaining drainage and limiting complications such as obstruction or stricture.
The procedure begins by mobilizing the ureter while maintaining its blood supply. The ureter is then aligned with the receiving ureteral or bladder tissue, and the cuff is positioned to support the connection. Sutures secure the tissues while preserving lumen patency and avoiding tension. The completed reconstruction is intended to provide drainage without leakage.
This technique may be selected when a ureter must be reconnected to bladder or ureteral tissue during ureteral reimplantation or broader urinary tract reconstruction. It also has a role in selected transplantation procedures. Across these settings, the approach addresses the need for a secure connection that supports urinary drainage while limiting obstruction, stricture, leakage, or reflux.
Evaluation centers on whether urine can pass through a patent, unobstructed connection and whether the anastomosis remains sealed. Clinicians also consider signs related to stricture, leakage, or reflux, because these findings indicate failure of one or more reconstruction goals. In transplantation and other complex repairs, reliable drainage is a principal measure of technical success.
