Introduction. In the 40 years since Gruntzig’s first angioplasty,1 percutaneous coronary intervention (PCI) has become one of the most frequently performed therapeutic interventions in medicine.2 Devices and techniques have evolved during this period and facilitated improved patient outcomes, so unlike Gruntzig it is no longer necessary to have a cardiac surgeon. Stent thrombosis (ST) is a catastrophic complication of coronary stenting, presenting as sudden death or nonfatal myocardial infarction (MI) in almost all cases. 1,2 Despite a decreasing frequency of ST in the current era, these dire consequences have generated intense clinical and research interest in prevention and management. In the early period of bare-metal stenting, ST. possible complications of dj stents include encrustation, fragmentation, migration, malposition, stenturia, stent fracture, forgotten stent, urinary tract. By Staff Writer Last Updated March 31, 2020. The recovery time after a ureteral stent depends on the amount of pain and number of complications, if any, that develop after the ureteroscopy procedure. Most patients typically go home within 48 hours of the surgery and can quickly return to work and their normal activities, according to Urology West. if you have a stent with a string coming outside the body through the urethra, sex may be difficult.

It was hypothesised that durable polymers used in the first generation DES would trigger the inflammatory process and induce stent thrombosis. 16,20 Biodegradable pol ymer coatings, which are composed of lactic or glycolic acids, facilitate drug delivery to the vessel wall and are fully resorbed by hydrolysis after drug release without causing any long. Patients that had had preoperative JJ stent placement were compared with those that did not. Inverse-probability-weighted regression adjustment (IPWRA) was used to examine the effect of preoperative JJ stent placement on the stone-free rate (SFR), length of hospital stay (LOHS), operative duration, and complications (rate and severity). By Staff Writer Last Updated March 31, 2020. The recovery time after a ureteral stent depends on the amount of pain and number of complications, if any, that develop after the ureteroscopy procedure. Most patients typically go home within 48 hours of the surgery and can quickly return to work and their normal activities, according to Urology West. In this review the technique, indication for and complications of percutaneous nephrostomy (PCN) and antegrade ureter stent insertion are described. ... In the case of severe infection and bleeding after PCN JJ-stent insertion may be contraindicated so long as there is no sufficient concomitant drainage via a PCN .

Other common complications associated with ureteral stent insertion include infection, ureteral tissue irritation and irregular peristalsis. Stent migration and failure can also occur. These complications are, however, most commonly found in those with forgotten ureteral stents or those with long-term stents. One particular study from February. The following predictors of procedural complications have been described: deceleration during rotablation >5,000 rpm; ... Popma JJ, Pichard AD, et al. Patterns of calcification in coronary artery disease. ... Popma JJ, et al. Sirolimus-eluting stents versus standard stents in patients with stenosis in a native coronary artery. N Engl J Med 2003. Information Conditions Centers. Ureteral stenting (also known as double J stent) is the procedure to place a thin, flexible plastic tube that is temporarily in the ureter to help urine drain from the kidney into the bladder in the case of a blockage. The ureters carry urine from the kidneys to the bladder. (Each kidney is connected to one ureter.). benefits and possible complications. I certify that I have read or had read to me the contents of this form and will follow any patient instructions related to this procedure. I understand the potential risks, complications and side effects involved with the proposed Ureteroscopy with laser without laser and Stent Placement. Despite tremendous advances in stent biomaterials and design, JJ stents are not free of complications and problems and the search for an ideal JJ stent may remain utopian. 1,2 A literature search of various ureteral stents was carried out and depicted so as to have a broad overall view of ureteral stents and their recent advances. THE IDEAL. . Ureteral stenting and nephrostomy help restore urine flow through blocked ureters and return the kidney to normal function. Ureters are long, narrow tubes that carry urine from the kidneys to the bladder. They can become obstructed – and urine flow blocked – as a result of various conditions. Your doctor may use image guidance to place a. AbstractBACKGROUND AND AIMS. Transplantation (KTx) is considered the best renal replacement therapy nephrologists can offer and improving its outcomes remains a. Positioning stent in head and neck radiotherapy seems to have benefit to prevent oral complications but it hasn’t been summarized by an evidence-based method. This review aims to evaluate the efficacy of positioning stents in preventing oral complications after radiotherapy. We conducted an electronic search in MEDLINE, EMBASE, Cochrane CDSR, and Cochrane. 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. It may also offer solutions for their correction. Stents should be monitored while in place, promptly removed when no longer needed, and changed periodically if chronically indwelling. Risk factors for complications should be minimized with high fluid intake, timely evaluation of clinical complaints, and aggressive treatment of documented infection. Stent thrombosis is a very serious complication, with mortality rates of over 60%. ... Premature discontinuation of antiplatelet therapy could lead to lethal complications such as late stent thrombosis. 10. ...
