The learning curve of sting method for endoscopic injection treatment of vesicoureteral reflux
ABSTRACT Objective: To identify how many endoscopic injection (EI) procedures, STING method, must be performed before reaching an ideal success rate when simulation training has not been received. Materials and Methods: The EI procedures performed by two pediatric urology fellows were investigated...

Materials and Methods: The EI procedures performed by two pediatric urology fellows were investigated. The study excluded patients without primary VUR and those with previous EI or ureteroneocystostomy, lower urinary tract dysfunction, and/or duplicate ureters. The EIs used dextranomer hyaluronate and the STING method, as described by O’Donnell and Puri. Groups number was determined by multiple statistical trials. Statistically significance differences were achieved with one combination that had 35 EI procedures each and with 3 different combination of patients, having 12, 24, and 36 patients, respectively. Therefore, groups were established 12 patients. The first fellow performed 54 EIs, and the second performed 51. Therefore, each of the first fellow's three groups contained 18 EI procedures, and each of the second fellow's 17. Results: The study included 72 patients and 105 ureter units. When the data from both fellows were combined, each of the three groups contained 35 procedures. For the first fellow, the success rates in the first, second, and third groups were 38.3%, 66.6%, and 83.3% (p = 0.02), respectively, and for the second fellow, the success rates were 41.2%, 64.7%, and 82.3% (p = 0.045), respectively. The increased success rates for both fellows were very similar. Conclusions: An acceptable rate of success for EI may be reached after about 20 procedures and a high success rate after about 35-40 procedures.http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1677-55382018000601200&lng=en&tlng=enLearning CurveEndoscopyVesico-Ureteral Reflux |
