- W4319032503 abstract "To evaluate the feasibility of a new technique for imaging-guided de novo retrograde ureteral double J (DJ) stent placement without cystoscopy in women.Eighty-four women referred for ureteral stent placement between April 2019 and January 2022 were included. In all the patients, the initial attempt for stent placement was performed in a retrograde fashion. Successful ureteral catheterization and DJ stent placement were considered as technical success. The fluoroscopy time required to catheterize the ureter and that for the entire procedure were recorded. Factors affecting the technical success rate and fluoroscopy time were examined.A total of 108 ureteral stent placement procedures in 84 women, with a mean age of 57.5 years (range, 19-85 years), were performed. The most common underlying pathologies were cervical (n = 33, 31%) and ovarian (n = 32, 30%) carcinomas. The most commonly involved segments of the ureter were the lower half (n = 44, 40%) and trigone (n = 39, 36%). The technical success rate was 81.5%, and it reached 93% in the case of lower-half ureteral obstruction. Distorted trigonal anatomy caused by external compression of the bladder wall by a mass was associated with a higher rate of technical failure (90.6% vs 47.8%; P < .001). The use of ultrasound guidance to guide the sheath to the ureteral orifice allowed for a significant decrease in the fluoroscopy time for ureteral catheterization (4.6 minutes ± 3.91 vs 2.26 minutes ± 2.32; P = .003) and that for the entire procedure (9.42 minutes ± 4.95 vs 5.93 minutes ± 4.06; P = .001).Imaging-guided de novo retrograde ureteral catheterization and stent placement can be successfully performed in a high percentage of patients within a reasonable fluoroscopy time without the need for cystoscopy in women." @default.
