Abstract

Urolithiasis is a common urinary tract disorder in dogs and a significant cause of lower urinary tract obstruction. The present case report describes the successful surgical management of a complicated case of obstructive urolithiasis in an 8-year-old male Pug, further complicated by a retained and kinked urethral catheter fragment. The animal was presented with a history of anuria, dysuria, and straining, along with reduced appetite and vomiting. Clinical examination revealed a distended urinary bladder, and radiographic evaluation confirmed the presence of multiple radiopaque cystoliths and urethroliths, along with a retained catheter fragment lodged at the base of the baculum, causing urethral obstruction. Initial attempts to relieve the obstruction using retrohydropropulsion were unsuccessful. Therefore, a combined surgical approach involving urethrotomy and cystotomy was performed under general anesthesia. Urethroliths and catheter fragments were successfully removed from the urethra, and multiple calculi were retrieved from the urinary bladder. Postoperative management included antibiotics, anti-inflammatory therapy, and fluid support, resulting in an uneventful recovery. This case highlights the importance of prompt diagnosis and surgical intervention in obstructive urolithiasis, particularly when complicated by iatrogenic factors such as retained catheter fragments. Early management is crucial to prevent life threatening complications and ensure favorable clinical outcomes.
