Summary
A calcified catheter encrustation in an ileal conduit (IC) caused obstructive uropathy and declining kidney function. Endoscopic fragmentation and removal of the encrusted catheter successfully restored renal function.
Area of Science:
- Urology
- Nephrology
Background:
- Ileal conduit (IC) urinary diversion is a surgical procedure for managing intractable urinary incontinence.
- Deterioration of renal function post-IC diversion necessitates thorough investigation to identify underlying causes.
Observation:
- A patient with an IC presented with worsening renal function, bilateral hydroureteronephrosis, and an atrophic kidney.
- Imaging revealed a calcified, tube-like structure within the IC causing obstruction.
Findings:
- Mercaptoacetyltriglycine (MAG-3) renogram was inconclusive for obstruction.
- Computed tomography (CT) identified a calcified catheter encrustation within the IC.
- Endoscopic fragmentation and removal of the encrusted catheter via the IC resolved the obstructive uropathy.
Implications:
- This case highlights a rare complication of catheter encrustation within an ileal conduit.
- Endoscopic management, adapted from percutaneous nephrolithotomy techniques, offers a viable solution for such obstructions.
- Prompt diagnosis and intervention are crucial for preserving renal function in patients with IC diversion.

01:20Disorders of the Urinary System
266
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
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...

01:22Ureters
405
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

01:21Inflammatory Bowel Disease V: Surgical Management
133
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:

01:23Urinary Bladder
491
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...

01:17Chronic Bowel Disorders: Introduction
420
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
