Magnetic resonance imaging following interstim®: An institutional experience with imaging safety and patient satisfaction

Abstract

Although we don't advocate the routine use of MRI following InterStim® implantation, our experience suggests MRI may be feasible under controlled conditions and without adverse events.

International Continence Society best practice statement for use of sacral neuromodulation

“…Two separate studies have shown that MRI studies of the extremities other than the head and body MRI scanning including the lumbar spine and pelvis can be performed safely with earlier and current InterStim devices. Elkelini 147 as well as Chermanski 161 reported the results from individual small series of patients studied without event using the interstim I device, using 1.5 and 0.6 Tesla machines. In one case, a generator (IPG) was found to be damaged after study due to leaving the magnet switch on, and both studies recommended setting the amplitude to zero and turning the magnet switch off.…”

Contribution of sacral neuromodulation to manage persistent voiding dysfunction after surgery for deep infiltrating endometriosis with colorectal involvement: preliminary results

“…The basis for this policy is that potential hazards such as motion, dislocation or torquing of the implanted pulse generator and heating of the leads may occur. However, according to studies based on a few patients, MR imaging with 0.6 or 1.5 Tesla machines may be feasible after Interstim 1 implantation under controlled conditions and without adverse events [31,32].…”
