Plain-English summary
A male cat with a urinary blockage was treated at a veterinary hospital, where he received either inhalant anesthesia or sedation for catheter placement. The study found that there was no significant difference in complications or the chance of the blockage returning between the two anesthesia methods. However, certain blood test results, like low calcium and high potassium levels, were linked to higher complication rates and a greater risk of the blockage coming back. Overall, the choice of anesthesia did not impact the cat's recovery, but monitoring blood levels was important for predicting outcomes.

Abstract
OBJECTIVES: The aim of this study was to evaluate the use of inhalant anesthesia vs sedation for urinary catheter placement in male cats with urethral obstruction. The primary outcome measures were the incidence of complications related to catheterization, the incidence of recurrent urethral obstruction (rUO; both during hospitalization and within 1 year) and survival. The secondary aim of this study was to evaluate the association between baseline serum biochemical concentrations and antispasmodic medications with complications and short-term rUO. METHODS: We carried out a retrospective review of records from a university teaching hospital from 2009 to 2020. Cats were included if diagnosed with a urinary obstruction, based on the presence of a large, painful and non-expressible bladder, a urinary catheter was placed and hospitalization occurred for a minimum of 24 h. Collected baseline data included age, breed, weight, serum biochemical concentrations and if cats underwent sedation or inhalant anesthesia for urethral catheterization. For the comparison of inhalant anesthesia or sedation, univariate logistic regression was used. RESULTS: There was no statistically significant difference in complications or the recurrence of obstruction in cats with urethral obstruction that underwent inhalant anesthesia compared with sedation. All serum biochemical concentrations were significantly associated with survival. Decreased serum ionized calcium was found to be statistically significantly associated with higher complication rates ( = 0.0086), as well as short-term recurrence of obstruction ( = 0.004). Increased serum potassium concentrations were found to be statistically significantly associated with the risk of short-term recurrent urethral obstruction ( = 0.0345). No significant difference was found between the use of antispasmodic medications with short-term recurrence. CONCLUSIONS AND RELEVANCE: No significant difference was found between complications or recurrence rates when comparing the use of inhalant anesthesia to sedation protocols. Baseline serum biochemical data were significantly associated with complications, survival and short-term recurrence rates.
