Use of the stomach for bladder replacement and urinary diversion
Annals of the Royal College of Surgeons of England
|July 1, 1978
Summary
The pyloric antrum of the stomach offers a superior alternative for urinary diversion and bladder replacement, showing excellent function in human clinical use since 1969.
Area of Science:
- Urology
- Surgical Innovation
- Gastrointestinal Surgery
Background:
- Current urinary diversion and bladder replacement techniques present significant limitations.
- The pyloric antrum of the stomach possesses unique characteristics suitable for urinary tract reconstruction.
Purpose of the Study:
- To evaluate the efficacy of using the pyloric antrum for urinary diversion and bladder replacement.
- To compare the pyloric antrum technique with existing methods for bladder reconstruction.
Main Methods:
- Surgical techniques utilizing the pyloric antrum for bladder replacement and conduit formation were developed.
- Initial trials were conducted in canine models, followed by human clinical application since 1969.
- Extensive postoperative studies were performed to assess functional outcomes.
Main Results:
- Canine studies demonstrated encouraging results for both bladder replacement and conduit creation.
- Human clinical application since 1969 has shown the pyloric antrum to function well within the urinary tract.
- Postoperative evaluations indicate successful urinary diversion and bladder replacement.
Conclusions:
- The pyloric antrum is a viable and potentially superior option for urinary diversion and bladder replacement.
- The technique offers advantages due to the pyloric antrum's blood supply, absorptive properties, urine acidification, and contractility.
- Long-term clinical data supports the efficacy and benefits of this surgical approach.

01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:21Inflammatory Bowel Disease V: Surgical Management
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

01:25Urinary Tract Calculi VI: Surgical Management
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
01:26Kidney Transplant II: Surgical Procedure
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
01:22Imaging Studies V: Intravenous Urography and Retrograde Pyelography
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

01:22Imaging Studies VI: Voiding Cystourethrography and Cystography
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
