Ureteral Double-J Stent

Double-J (DJ) stents are commonly inserted after ureteroscopy. There are several complications associated with the presence of DJ stent: urinary tract infection, stent encrustation, stent migration, and stent-related symptoms (SRS). SRS occur in up to 80% of patients and include pain, hematuria, and dysuria, all of which negatively impact the patient's quality of life. Physicians proposed the distal end of the ureteral stents might involve in SRS by over-simulating the trigone of bladder. The design of the distal end, made with a thinner loop than that of a standard DJ stent, is intended to mitigate SRS and reduce urine reflux.

The placement of a Ureteral Double-J Stent as an emergency treatment or preparation for endoscopy after Colic nephritis is very frequent. It is often poorly supported, most often by young patients. A rich symptomatology is related to the probe responsible for a limitation of activities that can have a strong socio-economic impact. The objective of this study is the identification of the predictive factors of poor tolerance.
