Perineal urethrostomies are associated with complications that may mimic primary causes of feline lower urinary tract disorders. Though postoperative 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 urinary tract infection and urolith formation.
会阴尿道造口术会引发一些并发症，这些并发症可能会模仿猫下泌尿道疾病的主要病因。尽管通过熟练掌握有效的手术技术可将术后尿道狭窄降至最低，但切除远端尿道可能会导致25%至30%的患者术后出现细菌性尿路感染。由产脲酶微生物引起的尿路感染可能会诱发鸟粪石尿路结石的形成。因此，必须权衡通过尿道造口术减少复发性尿道梗阻的预防益处与复发性细菌性尿路感染和尿路结石形成的长期易感性。
