Iatrogenic bladder rupture in individuals with disability related to spinal cord injury and chronic indwelling urethral catheters.

We present two cases of extraperitoneal rupture in chronically catheterized SCI patients following bladder instillation. Both patients were undergoing instillation of fluid through balloon catheters which likely occluded the outlet. We believe that rupture in both cases was iatrogenic, from elevated intravesical pressures during gravity instillation of fluid. Both patients experienced AD during these events. A procedure involving bladder instillation in chronically catheterized SCI patients should be performed by providers familiar with management of AD. Risk factors for iatrogenic bladder rupture during instillation procedures likely include chronic catheterization, small bladder capacity, instillation under significant pressure, and occlusion of the bladder outlet by a balloon catheter.
