Ca. Osborne et al., FELINE PERINEAL URETHROSTOMY - A POTENTIAL CAUSE OF FELINE LOWER URINARY-TRACT DISEASE, The Veterinary clinics of North America. Small animal practice, 26(3), 1996, pp. 535
Perineal urethrostomies are associated with complications that may mim
ic primary causes of feline lower urinary tract disorders. Though post
operative urethral strictures may be minimized by proficiency with an
effective surgical technique, removal of the distal urethra may result
in bacterial urinary tract infections in 25% to 30% of patients after
surgery. Urinary tract infections caused by urease-producing microbes
may induce struvite urolith formation. Thus the prophylactic benefits
of minimizing recurrent urethral obstruction by urethrostomy must be
weighed against a long-term predisposition to recurrent bacterial urin
ary tract infection and urolith formation.
