Unlikely , this bacteria is uncommon in UTI .

Thank you for your input. Is it possible that Coagulase-negative Staphylococci increases urine pH and causes apatite stones since it is on of Urea-splitting bacteria.

The association between nephrolithiasis and UTIs can be either (i) kidney stone formation developed following UTIs (the so-called ‘infection-induced stones’) or (ii) nephrolithiasis with subsequent UTIs as its complications (the socalled ‘stones with subsequent infections’). Whether they are infection-induced stones or stones with subsequent infections, the stones themselves are the important source of secondary infection.  It has been thought that types of bacteria in the stone nidus implicate the causative microorganisms involved in stone formation and the pathogenesis of

‘infection-induced stones’, whereas those found in the stone periphery implicate microorganisms entrapped into the stones during secondary UTIs (stones with subsequent infections). The latter should have microorganisms found only in the periphery of stone matrices, not in the stone nidus.

Thank you very much, Dr.Reddy for your input!

Some times stone itself produces injury in the kidneys which leads to the infections but your question has a worth and someone should go through it 

Thank you, Dr.Mahnood! Appreciated you found this topic interesting!

As a possible urea-splitting bacteria it more commonly originates struvite stones instead of calcium phosphate stones. Beware that not all apatite
