Summary
The Detour extra-anatomic stent (EAS) offers a viable alternative for urinary diversion in complex ureteric obstruction cases. This stent system can improve quality of life for carefully selected patients with malignant disease.
Area of Science:
- Urology
- Surgical Innovation
Background:
- Ureteric obstruction due to malignancy or complex strictures presents significant management challenges.
- Long-term nephrostomy drainage is often undesirable for patients with advanced disease or comorbidities.
Purpose of the Study:
- To evaluate the experience and outcomes of using the Detour extra-anatomic stent (EAS) for ureteric obstruction.
- To assess the efficacy and safety of EAS as an alternative to traditional urinary diversion methods.
Main Methods:
- Retrospective analysis of 20 Detour EAS implantations in 13 patients between 2001 and 2017.
- Indications included malignancy-related obstruction or injury; follow-up averaged 12 months.
Main Results:
- Successful drainage was achieved in all cases post-treatment or revision.
- Complications included urinary leaks and infections; one death was stent-related.
- Seven patients died from disease progression with functioning stents; five remain well.
Conclusions:
- The Detour EAS system is a suitable option for urinary diversion in selected patients.
- It can provide a good quality of life for patients with comorbidities and malignant disease.

Anatomical Positions
19.9K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Anatomical Terminology
27.0K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Anatomical Movements
15.6K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Cerebrum: Anatomical Overview II
4.9K
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...

Diencephalon: Anatomical Regions
5.4K
The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the...

Cerebellum: Anatomical Regions
4.6K
The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...
