Thanks, Karen. I appreciate your input. Thanks to Sharon and Tex, too. This is a great community of kind, caring and knowledgable people! :)<br><br>The vet collected a urine sample via cystocentesis yesterday. No catheter, but I believe the needle irritated an already inflamed bladder wall, and possibly broke a blood vessel. Since the cystocentesis, there has been intermittent, bright red spotting (in addition to the pink urine), although sometimes my piggie's urine looks completely clear. I have learned since yesterday that spotting can happen as a result of this procedure. I would not have consented to this procedure, as we previously obtained urine samples by merely squeezing the bladder, but I wasn't told (different vet). <br><br>We are waiting to get the results of the urine tests back before assuming antibiotics are necessary. I will also talk over pain meds with my piggie's regular vet tomorrow. My piggie only seems to be in pain while urinating/defecating -- her
appetite, behavior and habits are otherwise normal.<br><br>I am keeping her bladder flushed. Since the initial stone diagnosis last month, I have been syringing water to my piggie throughout the day (in addition to what she consumes on her own). I also used shilintong for 2 1/2 weeks (until the pink urine appeared yesterday); I have discontinued the shilintong as the stone now appears larger on x-ray. Something isn't working.<br><br>I am considering chanca piedra and I am wondering if anyone knows the appropriate dosage for a guinea pig. My understanding is that shilintong soothes the bladder and relaxes the urethra, while chanca piedra actually breaks up a stone.<br><br>Any guidance regarding chanca piedra will be appreciated. I have read conflicting dosage instructions on other websites. <br><br>Thanks again!<br><br>Kelly<p>
