A typical bowel preparation for shockwave lithotripsy involves a clear liquid diet the entire day prior to the procedure. Starting around 11 a.m., take two 5 mg bisacodyl tablets. Take these tablets with at least 8 ounces (240ml) of water. Even more water would be better. Generally, you will have a bowel movement within 6-12 hours. The bowel preparation may lead to mild dehydration, so be sure to drink plenty of fluids. And remember, unless specifically instructed otherwise, DO NOT EAT OR DRINK ANYTHING AFTER MIDNIGHT on the day before surgery.

Some patients, who may have more problems with constipation, may be asked to take one bottle (8oz) of magnesium citrate, instead of the two 5mg bisacodyl tablets. Your urologist/urologist nurse will inform you, if your urologist feels you may be better suited by taking the magnesium citrate instead of the two bisacodyl tablets.
