UroToday.com - Dr. Juan Corrales, et al. reported on a technique for the removal of ureteral stents in infants and children using a urethral sound. They performed this procedure on 12 children, 8 girls and 4 boys between the ages of 6 months to 13 years. The procedure was performed under general anesthesia. A 12 French Guyon sound was used in 2 older boys who were 18 and 13 years of age. An 8 French or a 10 French Van Buren sound was used in infants and children. Of the 12 patients, 9 had pyeloplasties while the remaining 3 had ureteral reimplantatations.

The group found that in 9 children, extraction with the sound was rapid, with the first attempt requiring an average of 15 seconds. In the remaining 3 cases extraction with the ureteral stents required 3 attempts. One of the patients was a small girl with a very small 3.7 French stent. They found no complications. No child had bleeding or pain to suggest tearing of any bladder urethral mucosa or disruption.

The group states that this technique is especially useful when standard endoscopic instrumentation is not available. The technique can be easily implemented in countries with limited resources. They speculate that the Guyon sound was more effective in the older boys because it has a more pronounced curvature. They feel this technique is simple and rapid and can obviate the endoscopic equipment - especially single use disposable items.
