Bresciani et al: Modified prepubic urethrostomy with body wall tunneling: Description of technique and long-term outcome in eight male cats
Veterinary Surgery 2, 2022

🔍 Key Findings

  • Modified prepubic urethrostomy (mPPU) was effective for managing proximal urethral obstructions in male cats.
  • All 8 cats regained voluntary urination within 24 hours postoperatively.
  • Early urinary incontinence and peristomal dermatitis occurred in all cats but were self-limiting.
  • Two cats (25%) required surgical revision due to stomal obstruction from weight gain and abdominal fat.
  • No intraoperative complications were reported in any of the 8 cats.
  • Follow-up (13–84 months) showed sustained urinary continence and owner satisfaction in all cases.
  • The rectus abdominis muscle tunnel likely increased outflow resistance, minimizing persistent incontinence.
  • Recurrent hematuria and dysuria occurred in 3 cats but were managed conservatively.

Multiple Choice Questions on this study

In Bresciani 2022 et al., on modified urethrostomy outcomes, what was the long-term continence status of cats post-mPPU?

A. Only 2 cats achieved full continence
B. All cats had persistent leakage
C. 4 cats required long-term meds for incontinence
D. Continence was restored fully in all cats
E. All cats required surgical revision for incontinence

Answer: Continence was restored fully in all cats

Explanation: Urinary continence was achieved in all cases by final follow-up without ongoing medication.
In Bresciani 2022 et al., on modified urethrostomy outcomes, what complication required surgical revision in 2 cats?

A. Urethral rupture
B. Stomal hemorrhage
C. Stricture at the rectus tunnel
D. Skin fold obstruction from weight gain
E. Peritonitis

Answer: Skin fold obstruction from weight gain

Explanation: Weight gain led to abdominal fat and skin folds occluding the stoma, requiring surgical correction.
In Bresciani 2022 et al., on modified urethrostomy outcomes, what was the most common early postoperative complication in cats undergoing mPPU?

A. Urethral stricture formation
B. Recurrent urethral obstruction
C. Peristomal dermatitis and mild incontinence
D. Urinary tract infection
E. Bladder atony

Answer: Peristomal dermatitis and mild incontinence

Explanation: All cats experienced mild incontinence and skin scalding early post-op, which resolved spontaneously.
In Bresciani 2022 et al., on modified urethrostomy outcomes, what surgical modification aimed to improve urinary continence?

A. Use of a bladder flap for stoma
B. Paramedian stoma positioning
C. Subcutaneous tunneling through sublumbar muscles
D. Tunneling through rectus abdominis muscle
E. Partial preservation of prostatic urethra

Answer: Tunneling through rectus abdominis muscle

Explanation: The urethra was tunneled through rectus abdominis muscle to increase resistance and reduce incontinence.
In Bresciani 2022 et al., on modified urethrostomy outcomes, what was the reported outcome for voluntary urination post-surgery?

A. Most cats required catheterization for >48 hours
B. All cats urinated voluntarily within 24 hours
C. Only 50% regained voluntary urination by 72 hours
D. Average time to urination was 96 hours
E. Indwelling catheters were left for 5 days

Answer: All cats urinated voluntarily within 24 hours

Explanation: Urination resumed within 24 hours in all 8 cats without need for prolonged catheterization.
