Reference excerpt

An ileal conduit urinary diversion is one of various surgical techniques for urinary diversion. It has sometimes been referred to as the Bricker ileal conduit after its inventor, Eugene M. Bricker. It is a form of incontinent urostomy, and was developed during the 1940s and is still one of the most used techniques for the diversion of urine after a patient has had their bladder removed, due to its low complication rate and high patient satisfaction level. It is usually used in conjunction with radical cystectomy in order to control invasive bladder cancer.

To create an ileal conduit, the ureters are surgically resected from the bladder and a ureteroenteric anastomosis is made in order to drain the urine into a detached section of ileum at the distal small intestine, though the distal most 25 cm of terminal ileum are avoided as this is where bile salts are reabsorbed. The end of the ileum is then brought out through an opening (a stoma) in the abdominal wall. The residual small bowel is reanastamosed with the residual terminal ileum, usually seated inferior relative to the anastomosis. The urine is collected through a bag that attaches on the outside of the body over the stoma. The bag is changed every 3 to 5 days, or as directed by a stomal therapist. The risk of infection is actually quite small, but there is a high risk of stomal breakdown if not cared for correctly. Another and very effective use of an ileal conduit is for systemic isolation of a kidney transplant, often due to bladder neuropathy that may pose an unacceptable risk of reflux and thus infection or obstruction, into the transplanted organ. The urostomy is fashioned as previously described and connected by ureteroenteric anastomosis to the transplant ureter. Urinary tract infections are unfortunately very common because stomas are natural colonisers of bacteria; in transplant patients, antibiotic treatment, often over a long term and more frequent appliance changes are effective but not curative countermeasures. The bag adheres to the skin using a disk made of flexible, adherent materials. Unfortunately, there can be problems with leaking and rashes (excoriation), and heavy physical exertion will exacerbate deterioration of the appliance. Sometimes the leakage occurs unexpectedly, and "ostomates" (as they are known) usually carry a spare appliance to deal with unexpected emergencies.

Worked examples

Example 1 — a first encounter with Ileal conduit urinary diversion

Start with the simplest possible case. Write down what Ileal conduit urinary diversion claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ileal conduit urinary diversion before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ileal conduit urinary diversion ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ileal conduit urinary diversion

In research: Ileal conduit urinary diversion appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ileal conduit urinary diversion in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ileal conduit urinary diversion is common in secondary-school and first-year university syllabi. It links to neighbouring topics Urologic surgery, so understanding it makes those chapters shorter.
In everyday life: Look for Ileal conduit urinary diversion outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
