Odie

• Patient:
  Odie, 8 year old male neutered cat.



• Presenting complaint:
  Urethral obstruction and inability to urinate starting 5 weeks previously. There was only a transient response to catheterization and antibiotics. Odie was being managed by repeated centesis.



• Clinical care and diagnostic studies before endoscopy:
  Odie was dehydrated and started on fluids after placing an urethral catheter. There was blood and protein on urinalysis. The complete blood count and chemistry profile were within normal limits. Contrast radiology and ultrasonography found bilateral renal calculi without evidence of ureteral obstruction. There were calculi within the bladder.



• Endoscopic procedure:
  A laparoscopic-assisted cystoscopic surgery removed approximately twenty calculi, each large enough to obstruct the urethra. Odie was re-positioned to perform a perineal urethrostomy. Two more calculi were identified with a 1.9 cystoscope and were removed with a basket catheter.



• Benefits of using endoscopy:
  The laparoscopic-assisted calculi removal followed by further removal of urethral calculi using a scope with basket catheters was minimally invasive (2 small holes) and confirmed complete calculi removal from the bladder. Cystoscopy via the perineal urethrostomy permitted removal of urethral calculi and a normal urethra. Stone analysis was done with concern directed toward the kidney stones. There were not operated at this time as there was no evidence of obstruction of the ureters.



• Case follow-up:
  Voiding without obstruction or hematuria during recovery, followed by discharge on the fourth day after surgery.
