Hey Jim,
Yes, unfortunately it isn’t uncommon for those with Crohn’s to suffer with kidney stones and I notice you have had also had a resection which increases the chances even more.
You will find you have the compounding effects of malabsorption, diarrhoea and increased uptake of oxalate coupled with an interference of excreting uric acid through the bowel.
With that in mind you may have mixed calcium/uric acid stones.
Theses are general guidelines as what to follow dietary wise to try and lessen the chances of developing the stones:
Calcium Oxalate stones:
Oxalate is naturally found in many foods, including fruits and vegetables, nuts and seeds, grains, legumes, and even chocolate and tea. Some examples of foods that contain high levels of oxalate include: peanuts, rhubarb, spinach, beets, chocolate and sweet potatoes. Moderating intake of these foods may be beneficial for people who form calcium oxalate stones, the leading type of kidney stones. A common misconception is that cutting the oxalate-rich foods in your diet alone will reduce the likelihood of forming calcium oxalate kidney stones. While in theory this might be true, this approach isn't smart from an overall health perspective. Most kidney stones are formed when oxalate binds to calcium while urine is produced by the kidneys.
Instead: Eat and drink calcium and oxalate-rich foods together during a meal. In doing so, oxalate and calcium are more likely to bind to one another in the stomach and intestines before the kidneys begin processing, making it less likely that kidney stones will form.
Uric Acid stones:
In addition to calcium oxalate stones, another common type of kidney stones is uric acid stones. Red meat, organ meats, and shellfish have high concentrations of a natural chemical compound known as purines. "High purine intake leads to a higher production of uric acid and produces a larger acid load for the kidneys to excrete," said Dr. Jhagroo. Higher uric acid excretion leads to lower overall urine pH, which means the urine is more acidic. The high acid concentration of the urine makes it easier for uric acid stones to form.
Instead: To prevent uric acid stones, cut down on high-purine foods such as red meat, organ meats, and shellfish, and follow a healthy diet that contains mostly vegetables and fruits, whole grains, and low fat dairy products. Limit sugar-sweetened foods and drinks, especially those that contain high fructose corn syrup. Limit alcohol because it can increase uric acid levels in the blood and avoid crash diets for the same reason..Eating less animal-based protein and eating more fruits and vegetables will help decrease urine acidity and this will help reduce the chance for stone formation.

Hopefully someone will be along that has actual experience with stones. Good luck Jim!
