Prepubic urethrostomy and placement of a caudal superficial epigastric flap for treatment of a self-mutilation injury in a serval

Abstract

A 10-year-old male serval was examined for treatment of a self-inflicted perineal wound that obliterated the ventral anocutaneous junction, penis, scrotum, testicles, and proximal portions of the caudomedial thigh muscles. Repair required placement of a caudal superficial epigastric flap and prepubic urethrostomy. Although it is generally preferable to delay repair of contaminated wounds until a healthy wound bed is established, circumstances related to wound location, affected tissues, and patient compliance led to a decision for immediate wound closure. In this serval, a history of food intolerance, recent diet change, eosinophilia, and eosinophilic granuloma-like skin lesions suggested that the self-mutilation injury was a result of food hypersensitivity, although foreign body or a spider bite could not be ruled out.

Outcome of caudal superficial epigastric axial pattern flaps in dogs and cats: 70 cases (2007‐2020)

“…First described by Pavletic in 1980 (Pavletic 1980a), the CSEAPF is reported in dogs and cats to cover multiple defects in the inguinal area, perineum, lateral body wall, prepuce and medial, lateral and caudal thigh (Lidbetter et al . 2002, Campbell 2003, Mayhew & Holt 2003, Woods et al . 2009, Clarke & Findji 2011, Watrous et al .…”

Treatment of Lower Urinary Tract Obstruction via Scrotal Urethrostomy in an Eastern Fox Squirrel (Sciurus niger)

“…[6][7][8] Other species in which urethrostomy has been documented include small ruminants, antelope species, camelids, equids, dogs, ferrets, a serval, and non-human primates. [9][10][11][12][13][14][15][16][17][18][19][20][21][22] A single case of urethrostomy in a rodent species has been reported; this procedure was performed as a salvage procedure in a male rat with preputial adenocarcinoma and subsequent penile amputation. 23 Complications of urethrostomy include anesthetic risk, stricture of the surgical site, recurrent ascending bacterial urinary tract infections, urinary incontinence, extravasation of urine, skin necrosis, and self-mutilation of the surgical site.…”

Laparoscopic-assisted prepubic urethrostomy: experimental model in rabbit

“…Skin healed as internal sphincter became functional. Cats which undergone PPU also had substantial improve on quality of life following urinary continence recovery (BAINES et al, 2001;CAMPBELL, 2003;BASS et al, 2005). Hematuria is also a common selflimiting complication in cats by BASS et al (2005), BERNARDE &VIGUIER (2004), andPHILLIPS &HOLT, (2006).…”

“…The surgical procedure followed the same principles as for PPU by laparotomy with regard to the establishment of the urethral orifice, with care taken to avoid tension and angulation of the urethra while creating the orifice (BAINES et al, 2001, CAMPBELL, 2003. The stay sutures allowed precise manipulation of the exposed urethra without causing further damage.…”

“…Moreover, lower pneumoperitoneum pressure minimizes possible respiratory and cardiovascular distress and postoperative morbidity (SCHIOCHET, 2006). During urethra dissection, special care was taken to avoid trauma to blood supply and innervation, which was considered relevant for surgical success (BAINES et al, 2001, CAMPBELL, 2003. Fine and precise dissection maneuver was improved by magnification provided by videoendoscopic system, as stated by others (FREEMAN, 1998).…”
