Abstrakt: Objective: Traditionally, double J stent removal in pediatric patients has required cystoscopy under general anesthesia. Magnetic stents allow for double J stent removal without the need for anesthesia. This work describes our initial experience with these stents.
Material and Methods: A prospective cohort study of patients under 14 years of age carrying magnetic double J stents from 2018 to 2021 was performed. Variables assessed included baseline diagnosis, surgical procedure, placement success rate, complications associated with use, and need for general anesthesia at removal.
Results: 23 stents (4.8 Fr, 15 cm-20 cm) were placed in 21 patients, 62% of whom were male. Mean age was 5.01 years (3 months-13 years). Indications for placement included Anderson-Hynes dismembered pyeloplasty (34.8%), endoscopic dilatation of the ureteropelvic junction (UPJ) (21.8%), cystoscopic dilatation of the ureterovesical junction (UVJ) (17.4%), endoscopic lithotripsy (13.1%), renal trauma (4.3%), suspected retroiliac ureter (4.3%), and cystoscopic drainage of pyonephrosis (4.3%). Mean time of stent use was 4.2 weeks. 3 complications (13%) associated with the double J stent - 1 urinary tract infection (UTI), 1 stent obstruction, and 1 distal stent migration - were recorded. 95.5% of magnetic stents were successfully removed without anesthesia.
Conclusions: Magnetic double J stents can be regarded as an effective alternative to conventional double J stents, since they avoid an additional surgical procedure with general anesthesia in pediatric patients.
