“…The studies were published over a period of 23 years (1992–2016) and included 21 prospective and 10 retrospective studies. These studies reported the effectiveness of specific MSs in population studies [1] , [2] , [3] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , in comparative studies between different MSs [28] and between MSs and JJ stents [29] , [30] . It should be noted that all comparative studies were retrospective in nature.…”

“…Obstruction may be caused either by extension of the disease or by the extrinsic compression of the tumour on the ureter. The decompression of the ureter preserves renal function and prevents the consequences of the obstruction [1] , [2] .…”

“…Complications include haematuria, flank or abdominal pain, encrustation, UTIs, sepsis, and VUR. High rates of migration, decreased peristalsis of the ureter and relative obstruction, the possibility of loss of patency due to the extrinsic pressure, and the need for frequent replacements, are some of the disadvantages [1] , [2] .…”

“…Patients with advanced malignant disease have a short life-expectancy and the quality of life should be taken into consideration when establishing a management plan. Frequent changes of JJ stents or the placement of a permanent nephrostomy have been related to deterioration in the quality of life of these patients [1] . In an attempt to avoid the frequent replacement of JJ stents or the insertion of permanent nephrostomies led to the introduction of metal mesh stents (MSs) in urological practice.…”

ObjectiveTo review the literature on the effectiveness, safety and long-term patency of ureteric metal mesh stents (MSs), as a variety of MSs have been used for managing malignant ureteric obstruction over the last three decades.Materials and methodsA systematic review using the search string; Ureter∗ AND (stent OR endoprosthesis) AND metal∗ was conducted on PubMed, Scopus, Web of science and Cochrane Library online databases in May 2016. Prospective, retrospective, and comparative studies including MSs were included. The primary endpoint was the patency rate and the secondary endpoint was complications.ResultsIn all, 324 publications were screened and 31 articles were included in the systematic review; 21 prospective and 10 retrospective studies. These studies reported the effectiveness of specific MSs in population studies, in comparative studies among different MSs, as well as among MSs and JJ stents. It should be noted that all comparative studies were retrospective.ConclusionThe experiences with vascular MSs, such as the Wallstent™ (Boston Scientific/Microvasive, Natick, MA, USA), were related to high occlusion rates, due to endoluminal hyperplasia, and long-term disappointing patency. The use of covered MSs designed for the vascular system was also unfavourable. The Memokath 051™ (PNN Medical A/S, Kvistgaard, Denmark) had better patency rates, but also higher migration rates. The long-term results were acceptable and rendered the Memokath 051 as a viable option for the management of malignant ureteric obstruction. The Uventa™ (Taewoong Medical, Seoul, Korea) and Allium™ (Allium Medical Solutions Ltd, Caesarea, Israel) MSs, specifically designed for ureteric placement, provided promising results. Nevertheless, the wide acceptance of these MSs would require well-designed clinical studies and long-term follow-up.

“…39,40 The durability of a metallic US is greater in patients with non-malignant obstructions, and metallic USs have been reported by Wang et al 41 to last up to nine months, and up to five years by Kadlec et al 42 Insertion of a metallic US is recommended in patients that have a greater risk of failure, such as those with malignant obstructions. 43 Despite the durability of the metallic USs, they can present complications in up to half of the patients, especially in patients with advanced stages of cancer. The complications include: abdominal pain, persistent hematuria, severe dysuria, and insufficient drainage.…”

An Update in the Use of JJ Stents

Introduction Ureteral stents are widely used tools in the daily practice of the urologist due to the fact that they solve the endo-and extraluminal ureteral obstructions, enabling an adequate urine flow. They are the preferred tool because they are easy to insert and versatile, and are used to treat various urologic pathologies; nonetheless, they are not exempt from complications. Objectives To present an update in the use of JJ stents, describing their main associated symptoms and complications, indications and newest developments. Materials and MethodsWe performed a literature review in the Embase, Pubmed and Google Scholar databases, with the following terms and cross-references: ureteral stent; diagnosis; treatment; and urology, restricting the search to the past 7 years. A total of 428 articles were found, and 49 were used in the revision. Results We described the symptoms and complications associated with the use of JJ stents and their prevention, their use in the treatment of lithiasis and oncologic diseases, the utility of metallic stents, and new designs and improvements in their development.Conclusions JJ stents remain a very useful tool in the daily practice of the urologist, but are not exempt from having adverse effects and complications. There have been advances that decrease the adverse effects associated with their use, mainly infection, symptoms associated to the insertion, and risk of incrustation.
