Final answer:
A urinary diversion is a surgical procedure that redirects the flow of urine into an isolated loop of the intestine, following ureteric detachment from the bladder. It is commonly performed in cases where the bladder has been removed or is non-functional. The ileal conduit and the continent urinary diversion are two primary methods for achieving this.
Step-by-step explanation:
The surgical procedure that involves diverting urine flow through an isolated loop of bowel is known as a urinary diversion. The two common types of urinary diversions are ileal conduit urinary diversion and continent urinary diversion, such as a neobladder. During an ileal conduit procedure, the ureters are detached from the bladder and instead attached to a piece of the small intestine, which is then brought through the abdominal wall to create a stoma. Urine is collected in an external bag, similar to an ileostomy bag. In the case of a continent urinary diversion like the creation of a neobladder, a portion of the intestine is used to create a new bladder that can store and pass urine through the urethra, following a cystectomy.
Patient factors such as existing conditions, expected quality of life, and personal preferences play a significant role in the choice of urinary diversion. Complications can include infections, blockages, and in some cases, the introduction of bacteria can lead to urinary tract infections.
