Introduction & Objective: Urinary catheters are different and each one is made for a specific purpose. Some patients have urinary catheters for long stays in their bladder, so its complications must be evaluated. In this study, the effects of two types of urinary catheters on the rabbit bladder pathology were compared. Materials & Methods: It this study a total of 20 New Zealand rabbits were randomly divided into 2 groups of 10 rabbits. Under general anesthesia, and following a lower midline incision, bladder was exposed and in groups 1 cystostomy with Nelaton catheter in 10 rabbit was performed and 10 other rabbits in groups 2 were placed under Systostomy with Foley catheter. 7 days after the surgery, a re-laparotomy with isolation of rabbit bladder tissue was performed for pathological assessment. All data extraction was done by 17.0 SPSS software. Statistical tests such as Chi-square, Fisher's exact test, and Mann-Whitney tests were used for data analysis. P-value ≤ 0.05 was considered significant. Results: In both the Foley and Nelaton catheter groups, the highest frequency intensity in inflammation was of grade 3. Although the group with a Nelaton catheter had more inflammation than Foley catheter group but this difference was not significant (P > 0.05). The samples of inflammatory cells were different from 5 to 80 percent. In Nelaton and Foley catheter groups, the highest frequency of five to ten percent of PMN was seen. The difference between the two groups in the mean severity of bleeding was not significant (P > 0.05). Foley catheter had less chance of infection than Nelaton catheter. Although the differences observed in the two groups was not significant in the chi-square test (P > 0.05). Conclusions: A comparison of the severity of inflammation, inflammatory cells, bleeding in the tissues of the bladder in pathological assessment and urinary tract infection demonstrated no significant difference between Nelaton and folly catheters. This indicates that none of the above two types of catheters had any particular preference.
