Traditional ureteral stents are commonly used in practice to relieve renal obstruction or as a scaffold to promote healing after endoscopic or open/ laparoscopic surgeries involving the ureter. However, there are many morbidities associated with stent placement either due to bladder irritation or backflow of urine to the kidney. The most commonly reported symptoms include urgency, urinary frequency, dysuria, incontinence, hematuria, suprapubic discomfort, and fever due to urinary tract infections and flank pain, which can occur in up to 80% of stented patients. Sometimes, the symptoms are poorly tolerated and can negatively affect patients' quality of life. Shao et al have studied the relationship between bladder filling and the renal pelvic pressure (RPP) in stented patients, which revealed that RPP increased mildly during bladder filling and increased dramatically during voiding, indicating urinary reflux, and thus encouraging early stent removal. Another study showed that patients with stents whose distal coils cross the midline are at higher risk of post-stenting morbidities. Replacement of the distal portion of the ureteral stent with a thin material may reduce bladder irritative symptoms and allow the ureterovesical junction to coapt, thereby eliminating urinary reflux.
