This study was conducted on 16 calves and 2 rams brought to F.U. Veterinary Faculty Clinics for a complaint of urolithiasis. After clinic, ultrasonographic and blood urea profile analyses it was determined that 5 calves and one ram possessed vesica urinea rupture, 5 calves and one ram had urethral rupture arid 6 had urolithiasis with unruptured vesica urinaria. Foley or Pezzer catheters were placed equally in the vesicaurinarias of these cases through flank approach. In rupture formed cases once vesica urinaria and abdominal cavity were thoroughly irrigated and defects were repaired, then the catheters were placed. All cases received postoperatively serum (Isolyte) and antibiotic (Dimisin) and non-steroid antiinflammatory drug (Fynadyne). The catheter's opinings were closed tem-porarily about 5-6 hours/ day duration 3-6 days after surgery and this interval increased daily 12 hours in the following days. The aim of this procedure was to allow urine force urethral stenosis to open and eventually let it flow through its natural course. Urine leaked initially through preputial orificium and then gradually gained its normal flow within 10-15 days. In conclusion, a successful result was obtained in all cases treated with this method. Additionally, with this method the breeding capabilities of all cases were maintained.
