Urethral entrapment by an overlapping dislocation of the pubic symphysis in a cat.

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.

Use of a T'LIFT transabdominal organ retraction device in two-portal laparoscopic ovariectomy in dogs.

OBJECTIVE: To describe the use of the T'LIFT transabdominal organ retraction device to suspend ovaries during canine laparoscopic ovariectomy (LapOVE) and compare its use to a transabdominal suspension suture (TSS). DESIGN: Randomized clinical trial. ANIMALS: Client-owned intact bitches (n = 30). METHODS: Dogs were randomly assigned either to group T, in which LapOVE was performed with the T'LIFT, or to group S, in which a TSS was used. Laparoscopic ovariectomy was performed by using a standard two-portal protocol. Signalment (age, weight, body condition score [BCS], fat score of the ovarian pedicle [FSOP]), overall operative time, ovarian resection time, and perioperative complications were compared between groups. RESULTS: No significant differences were found between groups regarding age, weight, BCS, or FSOP. Surgical times were not significantly different between groups. No significant differences in major or minor complications were recorded. Overall operative time was significantly shorter for the last half of the cases compared with the first half, for the overall population, and within each group. Ovarian resection time for the last cases was significantly shorter compared with that for the first ones only in group T. CONCLUSION: The T'LIFT was used to suspend ovaries for two-portal LapOVE, with no major complications noted. There was no significant difference in surgical times or complications compared with transabdominal suturing. CLINICAL SIGNIFICANCE: The T'LIFT can be considered as an alternative to transabdominal suture for ovarian suspension in dogs undergoing LapOVE.

Radical cystectomy and subsequent ureterohysterostomy in a bitch.

OBJECTIVE: To describe and report the outcome of a ureterouterine anastomosis after unilateral dehiscence of a ureterovaginal anastomosis after total cystectomy in a bitch. STUDY DESIGN: Case report. ANIMAL: A 10-year-old intact female border collie with a urinary bladder leiomyosarcoma. METHODS: The dog was diagnosed with an invasive urinary bladder tumor, treated by radical cystectomy and bilateral ureterovaginal anastomosis. Postoperative necrosis of the distal ureter led to dehiscence of the anastomosis on the right side. To preserve the right kidney, the right ureter was anastomosed to the right uterine horn, and a stent was placed across the uterine cervix. RESULTS: The dog recovered from surgery and regained satisfactory urine output. Both ureteral anastomoses were patent at 10 months postoperatively. At 12 months postoperatively, intraluminal obstruction of the uterine stent, loss of patency of the right ureter, and severe right renal hydronephrosis were noted. The owner declined nephrectomy, and the dog died 2 months later. CONCLUSION: This is the first published report of a ureterouterine anastomosis and stenting of the uterine cervix in a dog. The functional outcome was satisfactory for 1 year postoperatively. The uterine stent and distal ureter were eventually obstructed by soft tissue. CLINICAL SIGNIFICANCE: Ureterouterine anastomosis can be considered as a salvage procedure when other surgical techniques have failed.
