Kock pouch incontinence occurred due to efferent nipple valve perforation during catheterization in a spinal cord injury patient. Surgical revision successfully restored continence.
Area of Science:
- Urology
- Surgical Innovation
- Patient Case Studies
Background:
- The Kock pouch is a surgically created internal reservoir for urinary diversion.
- Maintaining the integrity of the nipple valve is crucial for preventing incontinence.
- Spinal cord injury patients may require urinary diversion and catheterization.
Observation:
- A patient with a spinal cord injury developed Kock pouch incontinence.
- The incontinence was attributed to perforation of the efferent nipple valve.
- The perforation resulted from an attempted catheterization that was unsuccessful.
Findings:
- Nipple valve perforation is a complication that can lead to Kock pouch incontinence.
- Successful catheterization is essential for preventing iatrogenic injury to urinary diversion components.
- Surgical revision can effectively address and repair a perforated nipple valve.
Implications:
- This case highlights the importance of careful catheterization techniques in patients with Kock pouches.
- It underscores the need for vigilance regarding potential complications of urinary diversion devices.
- Surgical revision offers a viable solution for restoring continence after nipple valve perforation.

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
Urinary Bladder
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...
Anatomy of the Genitourinary System II: Bladder and Urethra
The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
