Pararectal Cystotomy for Urolith Removal in Nine Horses

摘要

ObjectiveTo report outcome of horses after standing pararectal cystotomy for removal of uroliths.Study DesignCase series.AnimalsHorses (n=9) with cystic calculi.MethodsMedical records (December 1998-May 2007) of horses with cystic calculi that had standing pararectal cystotomy were reviewed. Signalment; urolith number, size, and type; surgical technique; sedation and analgesia protocols; intra- and postoperative complications and outcome were analyzed.ResultsUroliths (mean diameter, 6.37 cm; median, 6 cm; range, 3-10 cm) were removed intact without need for fragmentation. Eight (89%) horses had no complications and 1 horse (11%) developed persistent drainage from the perineal incision and incisional healing was prolonged. The complications resolved after wound revision, and although cystoscopy showed absence of uroliths, the clinical signs associated with cystitis recurred.ConclusionsCystic calculi can be removed safely in standing horses using a pararectal approach. The procedure was well tolerated and no serious complications were encountered.Clinical RelevancePararectal cystotomy allows removal of cystic calculi in standing sedated horses. The technique may offer an economic advantage over approaches that require general anesthesia.
