With struvite - what about a bout of juvenile cystitis?

In juvenile dogs, magnesium ammonium phosphate uroliths (struvite) occur most commonly . Chronic urinary tract infection with bacteria, such as Staphyloccus sp., E. coli, Proteus sp. and Streptococcus sp., predispose to formation of struvite uroliths.

I am not aware of in-utero struvite urolithiasis? I would think the PH of the urine and amniotic fluid is closely maintained and sterile?

Also I would have to consider a congenital malformation in the lower urinary tract i.e. diverticulum/stenosis etc?

That's pretty much what I was thinking - it would be interesting to know if mum has any issues with her waterworks, but I'd love to hear any of the pathology bods spout on mechanisms of urolith production in the foetus.

Hopefully, and more practically, it's a one-off which will get talked about at each (uneventful) booster consult for the next fifteen years or so....

follow up urine all clear no sign of crystals etc do you think it is possible this urolyth has formed in utero ?

Don't think shunt likely alsthough as so young is a possibility I suppose, owners bought 3 pups to add to their other 5 dogs!!! all 3 I saw last week for 1st vacc and they were all equally bright playful and noisy, of course being bichons they cried when injected!

Yes cystotomy as well and normograde flushing etc, castrated and created a permanent urethrostomy at scrotal site just bladder side of where stone was stuck.

Urate urolith? It's not shunting is it?

Wow. An unusual Sunday afternoon for you, then. Did you do a cystotomy as well?
