It was reported that, during a urethroscopy/cystoscopy and intracorporeal laser lithotripsy on (b)(6) 2023 (on a 10 year old canine, male castrated, mastiff, about 155 lbs), the scope stopped working during the fragmentation of the second urolith, and thus a urethrotomy was needed to remove the residual stone.A back-up flex-x2s scope was used for retrieval of a stone fragment since the surgeon was not able to scope the dog after needing to abort lithotripsy to confirm that all fragments were removed.The canine had to recover in the icu due to surgery ending after hours.He was transferred to fluids wards the following morning where he remained hospitalized for four more days than anticipated to ensure proper healing of the urethra and prevent urethral strictures resulting from the surgical conversion.The total delay to the procedure was about 4 hours.
