“…14 Unfortunately, ureteral stents are not free of complications and they are associated with the loss of quality of life in a high percentage of patients. 4 An obvious improvement in the present double-J ureteral stent design should be to reduce patient morbidity and to include biodegradation capability. BUS not only avoids a second removal surgery, thus reducing health costs, but it also prevents forgotten stent syndrome.…”

Objective: The aim is to assess the effectiveness of a biodegradable antireflux ureteral stent with heparin coating in a comparative study (BraidStent Ò -H) in an animal model for the treatment of iatrogenic ureteral perforation. Materials and Methods: A total of 24 female pigs underwent initial endoscopic, nephrosonographic, and contrast fluoroscopy assessment of the urinary tract. Afterward, unilateral iatrogenic perforation in proximal ureter model was performed. Then the animals were randomly assigned to Group-I, in which a double-pigtail stent was placed for 6 weeks, or Group-II, in which a BraidStent-H a biodegradable heparin-coated stent was placed. Follow-up assessments were performed at 1 and 6 weeks and 5 months. Results: In terms of therapeutic effectiveness, complete resolution was observed in 95.8% of Group-I animals and 87.5% in Group-II. No animals in Group-II showed vesicoureteral reflux (VUR) during the study; statistical significance was observed at 1 and 6 weeks versus Group-I. All stents in Group-II degraded without producing obstructive fragments and allowed distal ureteral peristalsis. Heparin coating was not efficient to reduce asymptomatic bacteriuria between groups. Pathologic assessment did not show any significance in the global score, but did in the ''fibrosis in muscular layer'' parameter, at the ureteral perforation healing area; Group-II showed higher healing quality. Conclusions: The biodegradable intraureteral BraidStent Ò -H is highly effective for the minimally invasive treatment of ureteral perforation, since it displays controlled and predictable degradation, avoiding the development of VUR as well as irritation of the bladder trigone. Unfortunately, heparin coating was not effective in avoiding stent-associated bacteriuria.

“…3 Unfortunately, stents are not free from side effects; they affect >88% of patients, with pain affecting *92.2%. 4 However, ureteral stents for IUP treatment have been proved effective. The main causes of stent-related symptoms are vesicoureteral reflux (VUR) and bladder irritation caused by the distal curl of the stent.…”

“…Patients with recurrent urolithiasis report more bodily pain, depression, and lower health scores compared to the average population with increased anxiety and stress even between events 13 . This is compounded by a stone event which may lead to ureteric stenting with its documented negative effect on patients’ quality of life 2,3,4 . Hence including PROMs in outcome measures while investigating urolithiasis patients is vital.…”

“…Bosio et al highlighted question GQ to characterize the feeling about the stent, and 51.6% of patients who experienced double-pigtail stent answered they would feel "unhappy" or "terrible" to have another 1 in the future. 22 The concept of material reduction within the bladder seems necessary in order to decrease bladder mucosal irritation. [7][8][9] The influence of the shape of the bladder loop showed controversial results.…”

OBJECTIVETo evaluate the stent-related symptoms using a new customized ureteral stent with a nonrefluxing silicone end-piece. METHODSBy decreasing the amount of material within the bladder, it should be possible to attenuate the stent-related symptoms. To minimize the amount of material, 17 consecutive patients already fitted with a double-pigtail stent for malignant ureteral obstruction agreed to be fitted with a customized stent where the bladder loop was replaced by a nonrefluxing silicone end-piece. The ureteral stent symptom questionnaire was prospectively administered to patients at baseline with doublepigtail stent and Day 15 after customized stent placement. RESULTSNo difficulty in the placement of the customized stent was encountered. No stent failure, no dislodgment and no calcification were observed 6 months after stenting. The scores for the main domain "Urinary symptoms" (34.4 § 3.6 vs 23.0 § 7.0; P = .0004) and the question "Global quality of life" (4.4 § 2.0 vs 2.4 § 2.1; P = .01) were significantly decreased by the replacement of the double-pigtail stent by the customized stent. CONCLUSIONThe customized ureteral stent may constitute an improvement in the field of stent-related symptoms and seems fit for use in its current shape. Studies exploring and exploiting new concepts are greatly required to reduce stent-related symptoms in all patients including those with cancer. UROLOGY 137: 45−49, 2020.
