A mare ageing 5years, foaled once, shows yellowish turbid urine since last 4 months. The mare voides the semi solid creamy chalky material from urinary bladder. The urination is frequent and it soils the both hind limbs, the skin got stained and seems to be burned but urine is alkaline (pH-9 on pH paper). On laboratory examination it showed crystals of calcium oxalate. The blood values are in normal range except BUN-45. The feeding and watering habit is normal and not affected. USG of bladder showed snowy-hyperechoic image with thick walled bladder. Cystoscopy showed yellowish hazy mucosal surface.
What could be condition, reason for this and line of treatment?
frequent urination of mare is a sign of
cystitis
Urolithiasis
estrus
But your finding in this case (lab+sonar) lead to clearly the first suggestion (cystitis).
Prolonged treatment regimes are essential since relapses are common because of dormant bacteria in the bladder wall. Bacterial cultures of urine and antimicrobial sensitive testing of cultured bacteria will help the veterinarian determine a course of treatment. Penicillin and trimethoprimsulfa are often used to treat the affected horse with good results.

Good Luck
This is suspected to be a chronic cystitis may be due to neglected treatment and presence of urinary crystals . as said in the former answer it needs a urine bacterial culture, change the food and increase the forages, shifting the urine pH for crystal dissolving
what you see is all normal for equine except the thick wall of UB so i recommend rexamination of UB especially cystitis is accompanied with infrequent urination. At the same time vaginitis and/or Endometritis should be considered.
Carefull examination of vagina by speculum and uterus by ultrasound due to these materials soils the both hind limbs.
