Plain-English summary
A 6-year-old male Chihuahua was brought to the vet because he was having painful urination and difficulty passing urine for five days. Tests showed that he had cystine crystals in his urine, leading to a diagnosis of cystinuria, a condition caused by an inherited defect that affects how the body processes a specific amino acid. The vet performed surgery to remove cystine stones from his bladder and urethra. After the procedure, the Chihuahua was able to urinate normally again.

Abstract
AbstractA 6‐year‐old, intact male Chihuahua was presented with stranguria and painful urination of 5 days duration. Cystine crystals were observed in low numbers in unstained urine sediment preparations, and a diagnosis of cystinuria was made. Uroliths were removed surgically from the urethra and the bladder, and mineral analysis indicated the stones were composed of 100% cystine. Cystinuria results from an inherited defect in renal tubular transport of cystine that affects many breeds and has been found as an autosomal recessive trait in Newfoundlands. Accurate identification of cystine crystals in urine is an important means of diagnosing cystinuria.
