“…For the tunica albuginea, a simple interrupted pattern was chosen over a simple continuous pattern for better holding strength and apposition despite requiring additional suture material and knots that may cause undesirable irritation at the incision site. In line with previously cited studies, 10‐14 a urinary catheter was used to divert urine and stent the anastomosis site after surgery. Although both dogs removed their urinary catheters prior to achieving the recommended minimum placement of 5 days, 15 both dogs attained a cumulative total of 6 days of catheterization postsurgery, which was within the recommended range of 5 to 14 days postsurgery, and this had no discernible effect on the quality of anastomosis integrity.…”

Objective: To describe penile urethral augmentation anastomosis (PURAA) for resection anastomosis (RA) of the canine penile urethra by using autogenous tissue in two dogs and to determine the mechanical properties of the augmentation technique in cadaveric specimens.Study design: Cadaveric study and two case reports. Animals: Sixteen canine cadavers and two dogs with urethral obstruction.Methods: The lower urogenital system was harvested from cadavers and randomized into two groups: simple (S) and augmented (AUG) RA of the urethra. Tensile strength and peak load were compared between the two groups. Two dogs were treated with PURAA for urethral obstruction secondary to juxtaurethral neoplasms.Results: Minimal tensile strength (MITS) and maximal tensile strength (MATS) were greater in the AUG group (MITS, 54.36 ± 24.0 N; MATS, 75.37 ± 34.79 N) compared with the S group (MITS, 11.78 ± 4.93 N, P = .0014; MATS, 13.74 ± 3.89 N, P = .0015). Both dogs recovered without complications. Histopathological examinations were consistent with a lipomatous mass in both cases. Both dogs had good medium-to-long-term outcomes. Conclusion:The augmentation technique improved the tensile properties of penile RA in normal cadavers and was associated with successful outcomes in two dogs.Clinical significance: Penile urethral augmentation anastomosis may help prevent stricture or leakage secondary to tension at the surgical site after penile urethral RA.

“…9,10 The range of urethral injuries can vary from contusions and lacerations to complete transections, and in severe cases, may involve urethral avulsion from the urinary bladder. 11,12 Urethral obstruction is a prevalent condition, representing 4.6% of all feline cases and 8.1% of all male cat cases seen in an emergency setting. 13 Underlying causes reported in cats include idiopathic obstructions (54%), urethral plugs (20%), urolithiasis (20%) and other mechanical obstructions, such as strictures and neoplasia (<5% of cases).…”

Case summary A 1-year-old neutered male domestic shorthair cat was referred with suspected uroperitoneum. Ultrasonography showed peritoneal effusion. CT further revealed a bilateral sacroiliac joint disruption associated with an overlapped dislocation of the pubic symphysis, resulting in an abnormal trajectory of the urethra with extramural urethral compression. An open reduction and internal fixation of the pubis with correction of the urethral trajectory was performed under general anaesthesia. The uroperitoneum was determined to originate from a cystocentesis. Relevance and novel information This report describes an unusual case of urethral obstruction secondary to overlapping dislocation of the pubic symphysis with urethral entrapment and concurrent bilateral sacroiliac luxation. To the authors’ knowledge, acute urethral obstruction owing to fractures of the pubis, without urethral laceration, has never been described.
