                              Fig. 5.15  Cystoscopic retrieval of urinary calculi with a stone basket
                              inserted through the working channel of the cystoscope. (a) The basket is
                              used to snare single irregular stones, or (b) multiple stones may be captured
                              in the device.



                              Inflammatory polyps may then regress if the chronic source of irritation
                              is removed.
                                The cystotomy is then closed with a single layer of sutures and the
                              bladder is replaced in the abdominal cavity. The second port site is closed
                              in  layers  (external  sheath  of  rectus  abdominis  muscle,  subcutaneous
                              tissue and skin) and the abdomen is insufflated and finally examined.
                              The camera port is then removed and the site closed routinely. Lidocaine
                              patches are applied to the areas around the skin incisions for local anal-
                              gesia. Following surgery, radiographs should be taken while the animal
                              remains anaesthetised to ensure that there are no residual calculi. Post-
