Vesicourethral anastomosis with 2-octyl cyanoacrylate adhesive in an in vivo canine model.

Objectives: To evaluate the effectiveness of 2-octyl cyanoacrylate adhesive (OCA) in the formation of vesicourethral anastomoses.

Methods: Open total prostatectomy was performed on 12 mongrel hounds. Of these, 8 had a vesicourethral anastomosis formed using OCA (4 with suture support and 4 sutureless).

Radiotherapy: effects on expanded skin.

Although the combination of radiation and tissue expansion has been associated with a significant rate of complications, the specific pathophysiology has yet to be clearly elucidated. The objective of this study was to develop a model to identify and examine specific histologic changes associated with tissue expansion and irradiation. Rectangular 50-cc silicone tissue expanders were placed subcutaneously over the midline dorsum of 18 adult New Zealand white rabbits.

Laser welded vesicourethral anastomosis in an in vivo canine model: a pilot study.

Purpose: We evaluated laser welding as an alternative method of forming the vesicourethral anastomosis.

Materials And Methods: Eight dogs underwent open total prostatectomy, including 4 in which the vesicourethral anastomosis was formed by 830 nm. diode laser welding using a chromophore doped albumin solder and 3 or 4 support sutures.

Extravesical cryosurgical approach for VX2 bladder tumor in rabbits.

This study characterized the VX2 bladder cancer model in rabbits and tested the feasibility of treating bladder cancer by extravesical cryosurgery. After the growth characteristics of the VX2 bladder tumor model were determined, the VX2 tumor was inoculated into rabbits at the dome of the bladder. One week later, three freeze/thaw cycles were followed by immediate surgical repair.

Iatrogenic Horner's syndrome in an experimental pig.

An adult domestic female pig (Sus scrofa) exhibited clinical signs of right-sided Horner's syndrome after experimental placement of a woven aortic stent followed by aortic catheterization. The clinical signs included a miotic pupil, ptosis of the upper eyelid, prolapse of the nictitating membrane, and enophthalmos. Necropsy revealed a large mass in the right midcervical region that encased or was in contact with the carotid artery, internal jugular vein, and vagus nerve.
