Nasopharyngeal stenosis (NPS) is an uncommon but potentially life-threatening condition in cats, capable of causing complete upper airway obstruction in severe cases. Carbon dioxide (CO₂) laser staphylectomy provides precise tissue ablation with minimal collateral thermal injury; however, restenosis could occur when used as a sole treatment modality. Balloon dilation can temporarily restore luminal patency, yet recurrence rates remain high when performed alone. This report describes an 8-month-old Korean Shorthair cat with complete nasopharyngeal stenosis that underwent CO₂ laser ablation as an initial intervention, followed by rapid restenosis within three days. A second procedure combining CO₂ laser ablation with endoscopic balloon dilation achieved short-term maintenance of nasopharyngeal patency. These findings suggest that, in cases of complete stenosis with a high risk of recurrence, a multimodal approach may be more effective than single-modality treatment.

Urethral obstruction in male cats, commonly caused by urolithiasis or FLUTD, can be life-threatening. Modified perineal urethrostomy (MPU), connecting the proximal urethra to the preputial mucosa, was performed in three male cats. Two cases with urolithiasis underwent concurrent cystotomy, and one FLUTD case received MPU alone. Two cats recovered uneventfully, while one developed re-obstruction from urinary sludge requiring revision. MPU achieved stable urinary patency and good cosmetic results in most cases, suggesting it as an effective alternative to conventional PU; however, recurrence associated with inflammatory or metabolic causes in FLUTD indicates the need for careful postoperative medical management.

Traumatic urethral rupture is uncommon in cats but may occur secondary to high energy trauma and can cause severe systemic compromise. An 8-month-old neutered male cat presented after trauma by hit-by-car, and retrograde urethrography confirmed a pelvic urethral rupture. Despite conservative management, urethral stricture subsequently developed. Surgical correction was performed by resection of the stenotic segment and urethral anastomosis via a pubic osteotomy approach. The cat recovered normal urination without complications, and no recurrence was observed during one year of follow-up. This case demonstrates successful surgical repair of post-traumatic urethral rupture and stricture in a cat using a pelvic osteotomy approach.
