Kidney stone

I am a thirtyfour year old female and have always been healthy. Around March last year I was taken ill with severe stomach aches. Medical research indicated stones in my left kidney and the ureter. One stone locked up the ureter, thereforeI was treated successfully with a lithotripter. Other stones 'disappeared' over time without me noticing it.
At the end of last year I got a colic again, with fevers. With medication I finished the holiday I was taking and upon returning in Holland, I visited my urologist in hospital. After waiting to see whether the stone would come out, we decided upon a treatment in January. Although I wasn't very ill or didn't have fever, I kept having some backpains and was tired. The treatment I underwent consisted of the entering of the ureter with a small microscope and removing all stones and the grit (is that a correct word???) that were found in the ureter.
During that 1,5 hour long treatment the whole of the ureter was cleaned.
Afterwards I was told that only three bits of 'grit' (very small) were left in my left kidney, where they couldn't be reached to be taken out.
It was decided that I would undergo some tests to see whether there was a chance of me getting stones in my kidney again, and if so, what could be done about it through diet, medication,... Recently I collected my urine for two days (a weekday and a Sunday) for 24 hours in order to be examinated. No results have come back yet.
In May this year I started a Padi Open Water course, which I finished successfully in June. As I was very enthousiastic about diving, I have been diving at least once a week since then and bought my own set. With the diving school -through which I'm sending you this mail- I am going for a diving holiday to Bonaire in two weeks time, hence the urgency of the question. I know that not much is known about kidney stones and diving, therefore I hope you can shed some light on the matter.
My question is thus: can one dive with stones in the kidney, or in my case, small pieces of grit?
Since my treatment in January I haven't had any colics or fever attacks anymore. I'm a very enthousiastic and responsible diver, always diving with people who've reached at least the Dive Master level. Could you let me know whether it's responsible to go on diving in Holland and now on holiday as well? Are there any known hazards?

Active renal disease, in particular the presence of renal stones is considered a contraindication to diving as a renal colic during a dive can put the diver at an increased risk, also a renal colic post dive can cause confusion with Decompression Illness.
The solution to this is to get rid of the stones as you have done. Since your doctors have told you that you have no troublemaking stones left in your kidney there is no reason why you cannot continue diving as long as you continue to remain under the required medical supervision to prevent recurrences.
