The effects of indwelling transurethral catheterization and tube cystostomy on urethral anastomoses in dogs

The influence of urinary diversion procedures on urethral healing was studi ed in 15 male dogs following transection and anastomosis of the intrapelvic portions of their urethras. Dogs were randomly assigned to one of three tr eatment groups and had urine diverted from the surgical site by indwelling transurethral catheter, cystostomy catheter, or a combination of transureth ral catheter and cystostomy catheter. There were no statistically significa nt differences in urethral healing when considering the different diversion methods, based on clinical, radiographic, and urodynamic parameters evalua ted.
