Urolithiasis in chronic inflammatory bowel disease
Abstract:
In a selected material of 228 patients with chronic inflammatory bowel disease (CIBD) the incidence of urolithiasis was 15% (95% confidence limit 11-21). The tendency to urolithiasis is significantly correlated to small-bowel resection and its extent and to obstruction in the urinary tract. On the other hand, there is no definite correlation to the duration or extent of the bowel disease. The significant correlation between urolithiasis and ileal resection is in agreement with the hyperabsorption of oxalate as an important cause of stone formation demonstrated by others. That local factors too play an essential role in the formation of urinary calculi is apparent from the increased incidence of urolithiasis in obstruction of the urinary tract. The incidence of urolithiasis was particularly high (22-25%) among patients with ileostomies. The few and negligible symptoms of and sequelae to, urolithiasis in CIBD encourage a conservative attitude.

Chronic Bowel Disorders: Introduction
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...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
