This report describes the simultaneous occurrence of fibrosarcoma and a urolith in the urinary bladder of a 12-year-old female terrier dog that was confirmed by pathology after excisional surgery. Clinical

The dog had some clinical signs such as frequent urination, hematuria and dysuria with anorexia and urinary tenesmus. Radiography confirmed the presence of a cystolith that was removed by surgery. During surgery, a solitary, pedunculated and round mass that had grown from mucosal tissue to the bladder space was observed. The mass was removed by excisional surgery and its pathologic section was prepared and stained by Hematoxylin and Eosin (H&E) and Masson’s trichrome methods. Microscopic findings in the tissue of the mass such as spindle fibroblastic cells with mild to moderate cellular pleomorphism and nuclear hyperchromasia, presence of mild mitosis figures, and chronic inflammation revealed the nature of the mass as a low-grade fibrosarcoma.

The cystolith was removed during depletion of the bladder and fibrosarcoma was removed by surgery to prevent further enlargement of the tumor and occupy the bladder space. Moreover, antibiotic therapy to avoid secondary infection was performed. Post-operation monitoring of the patient showed that there was no evidence for recurrence of the tumor within 3 months after surgery. Clinical relevance: Given the findings of this report, an occurrence of bladder fibrosarcoma has non-specific clinical signs that may challenge its differential diagnosis from other urinary-tract lesions.

Echoes are frequently observed in cat bladder contents through ultrasonography and often mentioned as incidental findings. No comprehensive study has been conducted so far on the precise echoes nature in the bladder contents ultrasonography in cats. The purpose of this study is to provide an accurate description of the cat bladder contents echoes and to specify the relationship between ultrasonographic findings and urinalyses. 30 adult DSH cats were investigated. Bladder ultrasonography was performed. The numbers of echoes in the bladder were qualitatively divided into four classes. At least 5 ml of urine was collected with cystocentesis. Urinalysis was performed on the urine sediment. The statistical analyses were done. Echoes were observed in 19 cases. The echoes were suspended in 17 of the cases, in those cases they were observed and clumped in 2 cases. Of the 19 cases where echoes had been observed in the bladder contents, 9 included oil droplets, 2 included struvite crystals and 4 included hematuria as reported in urinalysis. For 6 of the cats with echoes in the bladder contents, oil droplets, RBCs, and crystals were not reported in urinalysis. The number of echoes observed in the bladder in presence of RBCs, oil droplets, crystals, and leucocytes was not statistically significant (P>0.05). Based on this study, most of the echoes observed in the ultrasonography of cats’ bladder contents can be associated with the presence of oil droplets in the urine, which is in accordance with previous studies.

Cystitis and pyelonephnitis in ruminants most often result from ascending urinary tract infection (UTI). Investigating the prevalence of urine infection and its relationship with histopathological findings of bladder and kidney. This study was carried out on 353 slaughtered buffalos (143 female and 210 male) at Ahvaz abattoir, southwest of Iran. After slaughter, urinary samples were taken directly from bladder by sterile syringe. The bladder and kidney were inspected and samples from them were taken for histophatological study. All of the urine samples were incubated for isolation of bacteria on blood agar and MacConkey. Biochemical characterizations of the isolates were performed according to Bergey's manual of systemic bacteriology. Histopathological samples were taken from representative parts of each bladder and kidney and were stained with haematoxylin and eosin. Out of the 353 urine samples, 19 (5.38%) were positive. The percentages of infected cattle in female and male were 6.3% and 4.8%, respectively. These bacteria were isolated: E.coli (21%), Staphylococcus spp. (31.6%), Streptococcus spp. (15.8%), Proteus spp. (15.8%), Klebciella spp. (5.3%), Yercinia spp. (5.3%), and Actinimyces and Pasteurelle spp.(5.3%). In histopathological examination, 51(14.4%) and 5 (1.4%) of the buffalos had chronic cystitis and pyelonephritis, respectively. Bacteria were isolated only in 3 cases of chronic cystitis and 2 cases of pyelonephritis. Statistical analysis showed there was no relationship between isolation of bacteria from urine with cystitis and pyelonephritis. Some cases of chronic cystitis are not able to isolate of bacteria from urine and for causing pyelonephritis they need predisposing factors which caused urine retention.
