Retrospective study of proliferative urethritis in dogs: Clinical presentation and outcome using various treatment modalities in 11 dogs

ACVIM consensus statement on diagnosis and management of urinary incontinence in dogs

Urinary incontinence (UI) is a disorder of micturition that can occur in dogs of any age, sex, and breed depending on the underlying cause and time of onset. Diagnosis and treatment for various causes of UI in dogs have been described by multiple comprehensive single author review articles, but large prospective clinical trials comparing treatment outcomes in veterinary medicine are lacking. The objectives of this consensus statement therefore are to provide guidelines on both recommended diagnostic testing and treatment for various causes of UI in dogs. Specifically, pathophysiology directly related to the canine urinary system will be reviewed and diagnostic and therapeutic challenges will be addressed. A panel of 12 experts in the field (8 small animal internists [L. Adams, J. Bartges, A. Berent, J. Byron, J. Foster, A. Kendall, S. Vaden, J. Westropp], 2 neurologists [J. Coates, N. Olby], 1 radiologist [G. Oetelaar], and 1 surgeon [C. Adin]) was formed to assess and summarize evidence in the peer-reviewed literature and to complement it with consensus recommendations using the Delphi method. Some statements were not voted on by all panelists. This consensus statement aims to provide guidance for management of both male and female dogs with underlying storage or voiding disorders resulting in UI.

Preputial urethrostomy with preservation of the local anatomy in 4 dogs

OBJECTIVE

To describe a novel modified preputial urethrostomy with preservation of the local anatomy in 4 dogs.

STUDY DESIGN

Short case series.

ANIMALS

Four client-owned male dogs.

METHODS

Dogs presented for dysuria and urethral obstruction and underwent a modified preputial urethrostomy as a salvage procedure after the failure of previous treatments. Urethral stenosis or tear was confirmed by cysto-urethrography in all dogs. The preputial urethrostomy involved anastomosis of the pelvic urethra with the preputial mucosa after caudal laparotomy, without dissection of the prepuce or amputation of the penis. Owner follow up was obtained by telephone interview.

RESULTS

Urinary obstruction was due to urethral stenosis in 3 dogs and severe complications following perineal urethrostomy in 1 dog. The urinary obstruction was resolved in all dogs by the modified preputial urethrostomy. None of the dogs had signs of dysuria, urinary tract infection, or dermatitis immediately postoperatively. Two dogs showed signs of urinary incontinence from 15 days to 1 month postoperatively, which persisted throughout the follow-up period.

CONCLUSION

A functional urethral stoma was obtained in all dogs. This technique may be an alternative to prepubic urethrostomy in male dogs.
