A technique was developed for catheterization of the portal vein in rhesus monkeys (Macaca mulatta). Silicone rubber catheters (0.040 ID by 0.085 inch OD, or 0.030 ID by 0.065 inch OD) were surgically placed into the portal vein via the umbilical, inferior mesenteric, right colic, or ileocolic veins. The right colic and ileocolic veins proved to be the preferred route for catheterization. Both single end-hole and multiple end-hole catheters with 2 side holes were used. Catheter function was dependent upon proper placement within the portal vein and on maintaining patency. Single-hole catheters were successfully maintained by periodic flushing (2-3 times daily) with heparinized saline solution (1.5-4.0 units/ml), and multiple-hole catheters were best maintained by a continuous flow (1-2 ml/hour) of heparinized saline solution (1.5 units/ml). No adverse clinical effects due to the portal catheter were observed in any of the monkeys catheterized. The technique allowed placing the monkey in a restraint chair, thus enabling one to utilize the monkey in a conscious state.

The purpose of this study was to evaluate 2 methods of semen collection that could be used as terminal procedures in stallions with irreparable conditions, such as fractures or colic. Electroejaculation was attempted under general anesthesia. Forty-eight hours later, the ponies were castrated and 2 different epididymal sperm collection techniques were attempted by using a flushing or floating method. Additionally, the effect of supplemental seminal plasma was evaluated. Experimentally, electroejaculation was found to be a safe but ineffective method of terminal semen collection. Viable sperm cells were successfully recovered with both types of epididymal collection. The flotation method was least cumbersome and showed a tendency to be superior to flushing in terms of sperm motility and percentage of cells passing through glass wool/sephadex filtration, although differences did not reach significance. The addition of seminal plasma to epididymal spermatozoa prior to cryopreservation was of no value. In conclusion, either method of epididymal sperm collection is an acceptable method of terminal semen collection.

A colovesical fistula (CVF) is a pathological connection between the colon and the urinary bladder. Although they are uncommon, consequences can severely affect quality of life and mortality. Diverticula are the most common cause of CVF. This case details a patient's CVF diagnosis in the emergency department with unremitting gastrointestinal and urinary symptoms. A 78-year-old male patient with recent hospitalization for stroke and left carotid endarterectomy complicated by urinary retention treated with a Foley catheter presented to the Emergency Department with a chief complaint of hematuria and unremitting diarrhea. Foley exchange resulted in improved urinary retention and diarrhea during hospitalization. One day following hospital discharge, the patient presented again with a blocked Foley catheter and diarrhea. Foley irrigations resulting in near immediate diarrhea and lack of bladder filling on bladder scan portended to a diagnosis of colovesical fistula despite no history diverticula or colon malignancy. An abdominal/pelvic computed tomography scan and cystogram confirmed a colovesical fistula. This case highlights the need for consideration of colovesical fistula in a seemingly simple ED complaint of urinary retention. It is prudent to closely follow bladder scan volumes when flushing a Foley catheter. Given the significant comorbidities such as urosepsis and health care impact of repeat ED visits and hospitalizations, CVF can and should be entertained and rapidly diagnosed in the emergency department. Our case highlights the need for consideration of a vesico-colic fistula despite the absence of initial relevant risk factors.
