-ABSTRACTS POSTERS- ABSTRACTS PREPUCIAL URETHROSTOMY PERFORMED USING THE COATING TECHNIQUE

Abstract

Penile urethral obstruction in cats is a commonly seen clinical presentation. In cases where there is no response to catheterisation or medical intervention, surgery is needed to enable urination and correct uremia and hyperkalemia. Several surgical techniques have been described. Great care must be taken to minimize leakage in the anastomosis site and promote healing when performing the pelvic urethra and prepucial mucosa anastomosis. To achieve this, the line of anastomosis has been reinforced by covering the anastomosis with the bilateral bulbourethral tissue, m. ischiourethralis and m. ischiocavernosus using simple mattress sutures. This modifi cation, which varies from the technique performed by Yeh and Saroglu, has been termed the coating technique. Advantages of this RS S new technique over standard perineal urethrostomy have been discussed. This technique was used in the treatment of 49 cats with penile urethra obstruction presented to our clinic. 47 cats showed uncomplicated recovery. Stenosis developed after 1 month in 2 cases in which normal urination was resumed by performing the standard perineal urethrostomy technique. Following anastomosis, a male dog urethral catheter with an outer diameter of 2.6 mm was placed in each patient. The reasons for using a catheter in this technique were explained. In order to avoid infection, the catheter was changed at 7-day intervals, remaining in situ for 2 weeks and was removed after 14 days. All cats with obstruction returned to good health
