Efficacy of intra-urethral lidocaine jelly administration for prevention of post-cystoscopy dysuria in dogs.

Abstract

BACKGROUND: Post-cystoscopy dysuria is thought to be common in dogs. Limited information is available in veterinary medicine regarding strategies to prevent or mitigate post-cystoscopy dysuria. HYPOTHESIS/OBJECTIVES: Determine the efficacy of intraurethrally administered lidocaine jelly in combination with current standard-of-care pain control (eg, epidural anesthesia, nonsteroidal anti-inflammatory drugs) for prevention of post-cystoscopy dysuria. ANIMALS: Fifty-one client-owned dogs presented for cystoscopy or other cystoscopically guided interventions. METHODS: Randomized, placebo-controlled, double-blinded, and clinical study. All dogs undergoing cystoscopy for common indications were considered for enrollment during the study period with owner permission. Dysuria scores were compared between groups on days 0-7. RESULTS: Twenty-six dogs were included in the lidocaine group and 25 in the placebo group. No significant difference was found in the frequency of postprocedure dysuria between groups. Twenty percent of all dogs exhibited dysuria on day 1 after cystoscopy, but decreased to 11% by day 5 (P&#xa0;<&#xa0;.001). CONCLUSIONS AND CLINICAL IMPORTANCE: Intraurethral administration of lidocaine jelly might not be necessary to decrease the frequency and duration of postprocedural dysuria. Dysuria resolved in most patients undergoing cystoscopy by day 4. This information might be helpful for owner education and preparation of dogs for cystoscopic procedures.
