Introduction Ureteral obstruction can be occurred by benign condition such as ureteral stricture, or malignant disease. It is important that decompression of the ureteral obstruction and preserving renal function. First reported of double-J stents as a treatment for ureteral obstruction in 1978[1], Up to recently, ureteral obstruction generally was managed by indwelling double J stents. Advantages of double J stents are easy to inserting and rapid relieving of obstruction. Despite of advantages, they have some adverse side effects. Early side effects are stent discomfort, irritative lower urinary symptoms, hematuria, bacteriuria, fever, flank pain. Late side effects are stent migration, encrustation, fragmentation, forgotten.[2, 3] Other important drawback of double J stents is high rates of failure in management of ureteral obstruction by extrinsic causes, such as advanced malignancy.[4, 5] hence, the use of double J stents in malignant ureteral obstruction is controversy. Other option of decompression of ureteral obstruction is percutaneous nephrostomy (PCN). Although PCN has high successful rate for decompression of the ureteral obstruction, low quality of life by the external tube with drainage bag and easy dislodgement makes urologist hesitate to keep PCN to patients. To remedy shortcoming of double J stents and PCN, various kinds of new stents have been developed; coiled metal wire stents, (Resonance, Cook Urological, Indiana, USA) metal coil-reinforced double J stents, (Silhouette, Applied Medical, Cleveland, USA) segmental thermo expandable metal alloy stents (Memokath 051, PNN Medical, Denmark) self-expandable covered metallic stents (UVENTA, Taewoong Medical, Korea), and so on. To our knowledge this study represents the... ... middle of paper ... ...t al., Use of a segmental thermoexpandable metal alloy stent in the management of malignant ureteric obstruction: a single centre experience in the UK.

Transcatheter aortic valve replacement or TAVR is the latest technology used principally for the treatment of aortic stenosis, a condition in which one of the major valves of the heart, the aortic valve, becomes tight and stiff, usually as a result of aging (3). Since many patients who need aortic valve replacement for aortic stenosis are too sick to undergo major valve replacement surgery, they are unable to get the treatment they need. With the transcatheter aortic valve, this issue is bypassed because this valve can be implanted in the heart by accessing the patient’s heart through an artery in the groin. The valve can be inserted through a wire that can be pushed to the heart and the old valve is simply pushed to the side when the new valve is implanted. This technology has been in use in the US with Edwards’ Sapiens valve since 2011 and has saved the lives of many patients with aortic stenosis (4). Medtronic’s CoreValve uses similar technology and has won patent fights in Europe and has been in use internationally. However, within U.S., Medtronic has not been...
BioPatch, and alternatives like Tegaderm CHG, are an important first step in helping prevent catheter-related bloodstream infections (CBIs). As CBIs rank among the most frequent and potentially lethal nosocomial infections, the need for a device to cut down infections at the insertion site has increased. The growing numbers of infections has driven companies to consider a three-tiered approach: a maximal aseptic barrier at insertion, proper site maintenance, and hub protection. With BioPatch and alternative products catheter sites receive that maximal aseptic barrier to prevent bacteria growth.
Many people never find out that they have had stones in their kidneys. Some stones are small enough to flow through the kidney without ever causing any pain. These are called "silent stones"(Ford-Martin & Odle, 2005) Kidney stones cause problems when they get in the way of the normal flow of urine. They can block the flow through the ureter that carries urine from the kidney to the bladder. “The kidney is not accustomed to experiencing any pressure. When pressure builds from backed-up urine, it causes hydronephrosis” (Ford-Martin & Odle, 2005). If the kidney is subjected to this pressure for a while, there may be damage to the fragile kidney structures. When the kidney stone is lodged further down the ureter, the backed-up urine may also cause the ureter to swell. Because the ureter is a musc...
The purpose for the stent was to hold the coronary artery open to allow the blood to flow more freely.

Many experiments later, a device was born. In the late 1960s a man by the name of Carpentier developed the first annuloplasty ring (Christenson & Kalangos, 2009). He created the device in an attempt to reduce the size of the mitral valve and as a result decrease the severity of the mitral regurgitation (Lantada et al., 2009). Annuloplasty rings are designed to aid in the repair of the mitral valve. The repair of a mitral valve is preferred over complete replacement. This is mainly due to the fact that the patient is not required to use long term drug therapy following surgery (Buckner et al., 2010). After a valve has been repaired, the annuloplasty ring is sutured onto the patient’s native mitral annulus. The ring not only reconstructs the shape of the mitr...
Endovascular stent graft repair is designed to help reinforce a weakened aorta. Endovascular surgery is performed inside the aorta using thin, long tubes called catheters to place a stent surrounded with a fabric liner. Endovascular stent grafting uses an endovascular stent graft to reinforce the wall of the aorta and to help keep the damaged area from rupturing and developing into a potentially serious health problem that can be fatal and cause massive internal bleeding.
According to Batshaw, Roizen, and Lotrecchiano (2013), patent ductus arteriosus (PDA) is “the persistence of a fetal passage permitting blood to bypass the lungs” (p. 745). This is an inherited heart condition in which the ductus, a small pathway between the pulmonary and the aortic, valves remain open. This cardiovascular problem usually occurs in low birth weight infants. The blood vessels usually naturally closes after birth (Batshaw et al., 2013, p. 96). It becomes atypical if it remains open after the neonatal period. The structure usually closes in typical developing newborns around the initial 24 hours, and anatomical closure is supposed to follow several weeks later (Stanford Children’s Health, 2015). At the point when the ductus arteriosus stays open, the blood from the oxygen-rich aorta blends with the oxygen-poor pulmonary artery causing the higher chance of blood pressure in the lung pathways (U. S. Department of Health and Human Services, 2011). Certain children who have patent ductus arteriosus may be given medication, relying upon the circumstance to standardize the blood and oxygen levels until surgery is performed. Doctor can treat this condition by providing pharmaceutical medicine, catheter-based procedures, and surgery (U. S. Department of Health and Human Services, 2011).
2013). Inappropriate use of urinary catheter in patients as stated by the CDC includes patients with incontinence, obtaining urine for culture, or other diagnostic tests when the patient can voluntarily void, and prolonged use after surgery without proper indications. Strategies used focused on initiating restrictions on catheter placement. Development of protocols that restrict catheter placement can serve as a constant reminder for providers about the correct use of catheters and provide alternatives to indwelling catheter use (Meddings et al. 2013). Alternatives to indwelling catheter includes condom catheter, or intermittent straight catheterization. One of the protocols used in this study are urinary retention protocols. This protocol integrates the use of a portable bladder ultrasound to verify urinary retention prior to catheterization. In addition, it recommends using intermittent catheterization to solve temporary issues rather than using indwelling catheters. Indwelling catheters are usually in for a longer period. As a result of that, patients are more at risk of developing infections. Use of portable bladder ultrasound will help to prevent unnecessary use of indwelling catheters; therefore, preventing
Different studies had different result numbers or different percentage reduction rates which was primarily based on their indifferences in regards to study design utilized and sample size. As evidenced by research results (Magers, June 2013) and (Welden, 2013), these showed a reduction of urinary catheter days resulted in reduced CAUTI rates. Though different outcome results between the different research studies, they all strongly significantly supported the notion that a nurse-driven protocol to assess and evaluate the appropriateness and use of urethral catheter compared with a no protocol is essential to help in the reduction of CAUTIs. Interpreting these results, (Meddings et al., 2013) showed a drop greater than 52% in CAUTIs and a decrease in catheterization by 37%. The study results from the six scholarly research study articles showed nearly similar or corresponding outcomes. The results were significant enough to support the PICO question. In general, though the difference in sample size, the results still strongly supported excellent outcomes when a nurse-driven protocol is used to evaluate the necessity of continued urethral catheter use.

“The Nephrology Nursing Journal” was initially published in 1974, and is a refereed clinical and scientific resource that provides current information on a wide variety of subjects to facilitate the practice of professional nephrology nursing (ANNA, 2015). Its purpose is to disseminate information on the latest advances in research, practice, and education to nephrology nurses to positively influence the quality of care they provide (ANNA, 2015). It is designed to meet the educational and information needs of nephrology nurses in a variety of roles at all levels of practice, while also serving as a source of knowledge for non-nephrology nurses. (ANNA, 2015). Its content expands the knowledge base for nephrology nurses, stimulates professional growth, guides research-based practice, presents new technological developments, and provides a forum for review of critical issues promoting the advancement of nephrology nursing practice (ANNA, 2015).
After further multidisciplinary team meetings with the involvement of John the treatment option of automated peritoneal dialysis was implemented (NSF 2004). Once the Tenchkoff catheter had been inserted, education and training completed John was ready for discharge home.
