Abstract:
Perforation of the small bowel during SWL is reported for the first time. The patient was treated in the prone position for a ureteral stone with 4500 shockwaves. There were no underlying or predisposing factors for the damage to the gut with the exception of the large number of shockwaves at a high energy setting. It is concluded that SWL in the prone position with shockwaves traversing the peritoneal cavity carries a risk of damage to the bowel. A reduction of the number of shockwaves and the energy level should be considered in this setting.

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...
