Zystotomie mit und ohne temporärer Implantation eines präpubikalen Ballonkatheters zur Behandlung der obstruktiven Urolithiasis beim kleinen Wiederkäuer: eine retrospektive Studie

Abstract

The medical records of seventeen male small ruminants that had been referred to the Veterinary Teaching Hospitals of Zurich and Bern, Switzerland, between 1992 and 1997, for treatment of obstructive urolithiasis were reviewed and the short-term outcome evaluated. All seventeen animals were treated by cystotomy and antegrade positive pressure flushing of the urethra. In twelve animals, a prepubic foley-catheter was additionally implanted temporarily into the bladder (tube cystotomy for 8 - 12 days; mean = 10 days). Ten of twelve animals (83 %) with tube cystotomy, but only one of five animals (20 %) without tube implantation were released from the clinic. The prepubic catheter allows free flow of urine during the postoperative period until inflammation of the urethra at the obstruction site has subsided. The results of this retrospective study suggest, that tube cystotomy as compared to cystotomy without tube implantation increases the short-term survival rate of small ruminants with obstructive urolithiasis. Long-term follow-up by telefon conversation with the owners between 2 and 4 years after surgery revealed, that six non castrated animals with tube cystotomy were successfully used for at least one reproduction period and one castrated goat survived for more than 4 years.
