Laparoscopic augmentation cystoplasty: a comparison between native ileum and small intestinal submucosa in the porcine model.

Objectives: To determine the feasibility of laparoscopic augmentation cystoplasty (LAC) in the porcine model and to compare LAC using standard bowel vs a small intestinal submucosa (SIS) allograft.

Materials And Methods: Fourteen female pigs underwent LAC; six had standard ileal AC and eight AC with SIS. All the pigs had limited cystometrogram studies before surgery to determine bladder capacity.

A dorsal approach for the removal of the nasal septum in the horse.

Objective: To describe and evaluate a technique involving a dorsal approach for the removal of the nasal septum in adult horses.

Study Design: Retrospective clinical study.

Animals: Four client-owned horses.

Rupture of the peroneus tertius tendon in 27 horses.

The purpose of the study was to identify factors influencing the outcome and prognosis of rupture of the tendon of the peroneus tertius muscle in 27 horses. Information on history, physical examination findings, diagnosis, treatment, and final outcome was summarized from medical records. Long-term follow-up information on horses was obtained by telephone survey.

Secondary azoospermia after vasovasostomy.

Objectives: To determine the frequency of secondary azoospermia after microsurgical vasovasostomy and to determine what factors increase the risk of its occurrence.

Methods: We performed a retrospective review of three surgeons' experience. Patency was defined as the presence of sperm in at least one postoperative semen sample.

Long-term outcome analysis of Starr plication for primary obstructive megaureters.

Purpose: The Starr technique of tapering megaureters was first reported in 1979. Although this method of ureteral plication is well known, to our knowledge there are no clinical studies regarding outcomes. We report the first long-term outcome results with the Starr technique for primary obstructive megaureters.

Patient use of the internet for information in a lung cancer clinic.

Study Objectives: To determine how frequently patients attending a lung cancer clinic use the Internet for their own health information, to determine whether there are demographic differences between Internet users and nonusers, and to determine how patients compare the quality of Internet information with other sources of lung cancer information.

Design: Sequentially administered patient questionnaire. One hundred eighty-four patients were surveyed, and 139 patients (75.

Varicocele: current concepts in pathophysiology, diagnosis, and treatment.

Although significant advances have been made in the understanding of varicoceles, a clear pathophysiologic mechanism remains elusive. Most likely, a varicocele is the result of a multifactorial process. Appreciation of the complex venous drainage of the testis remains a key to maximizing the chances for treatment success.

Hematology of equine fetuses with comparisons to their dams.

The Hematologic values of 19 equine fetuses between 202 and 238 days gestation were compared with those of their dams. The red blood cell (RBC) count, hemoglobin concentration, hematocrit, and mean corpuscular hemoglobin concentration were significantly lower in fetal blood, while the mean corpuscular volume, mean corpuscular hemoglobin, and red cell distribution width were significantly higher. Mares had a significantly higher nucleated blood cell count than fetuses, and all nucleated cells were leukocytes (WBC).

Effects of delayed serum separation and long-term storage on the measurement of thyroid hormones in equine blood samples.

Studies were conducted to determine the effects of delaying the separation of serum from the clot and of long-term storage of serum samples on the measurement of thyroid hormones in blood from horses using a fluorescence polarization immunoassay. The measured concentrations of T3 and T4 were not affected by leaving serum on the clot for as long as 24 hours at room temperatures. Storage of serum for 19 to 22 months at -20 degrees C resulted in significant increases of measured T4, but not T3.
