Metal stents are effective for relieving ureteral obstruction but success regarding patient tolerability has been variable. We present our single institution experience with long-term metal ureteral stent placement Data was collected from 68 patients that had long-term ureteric stents placed for more than 6 months for various causes. Flank pain, irritative bladder symptoms and hematuria were the predominant problems. Other symptoms such as gross haematuria, lion pain, suprapubic pain were minimal as the patients handled these symptoms for more than 6 months This is used for short term stents (needed for 1 week or less). A nurse practitioner can do this in the office within days of your surgery. Ureteral stents that do not have a visible string, or were placed to allow a longer healing period, will require a minor in-office procedure However, the long-term failure rate of stents has been high, especially in cases of malignant ureteral compression. 1 Segmental metal mesh stents and Resonance metallic stents seemed promising at the beginning, but the long-term results were not outstanding.3, 4, 5 Although the exact cause of stent failure is not completely understood, stent.

Long-Term Follow-Up of Yearly Replaced Double Internal Stents for Extrinsic Malignant Ureteral Obstruction J Endourol. 2020 Sep 1. doi: 10.1089/end.2020.0469. Online ahead of print An indwelling ureteral stent is commonly used for relief of ureteral obstruction. However, few reports have documented the frequency of febrile urinary tract infection and changes in renal function in patients with long-term ureteral stent placement The ureter is the tube that carries urine from your kidney into your bladder. A stent is a thin hollow plastic tube used to hold your ureter open and allow urine to flow. The stent may stay in for several weeks. Long-term stents will stay in longer and need to be replaced within a certain period of time Resonance®; Metallic Ureteral Stent. Used for temporary stenting of the ureter in adult patients with extrinsic ureteral obstruction. This stent is intended for one-time use. This product line is serviced by the following clinical division(s) A 'ureteral stent' or 'ureteric stent' is a thin, hollow tube inserted into the ureter. Ureters are thin tube-like-organs which connect kidneys to the urinary bladder, to allow urine flow from the kidney. The stent is longer than the actual ureter and tube-ends are usually coiled

A stent is inserted during a short, outpatient procedure that requires sedation or regional anesthesia. Lifelong maintenance is required—stents need to be replaced every six months to year. Stenting is typically a temporary treatment that is used in people who cannot have surgery to reconstruct the ureter Internal double-J ureteral stents were designed from a urine-compatible polymer (C-Flex), and 35 stents were placed in patients. The overall patency rate for the stents was 80%, with most stent failures occurring before 2 months; the follow-up period ranged from 2 to 16 months, with a mean follow-up for all stents of 5.0 months Ureteral stents are considered to be a long-term mucosal contacting implant and testing should include, but is not limited to, mucosal irritation, sensitization, cytotoxicity, chronic systemic. Objective To define which long-term stent would work best in malignant ureteral obstruction (MUO) and benign ureteral obstruction (BUO), focusing on their mechanisms of action, price and insertion approach. Methods A systematic review was developed using the MEDLINE and Scopus databases and in accordance with the PRISMA checklist. There were no language restrictions for the search. Studies. A ureteral stent is a specially designed hollow tube placed in the ureter (the tube that carries urine from your kidney to your bladder). Made of flexible plastic material, the length of an adult stent is typically 22 to 30 centimeters long, extending from the kidney to the bladder, with a coi

Ureteral stents passively dilate the ureter; urine flows through the center of the hollow stent as well as around the stent, facilitating the passage of debris . Stent insertion initially increases ureteral peristaltic activity, but with time, the frequency and amplitude of ureteral peristalsis decreases [ 3-5 ] Objectives: To assess the long term complications of JJ stent, the management of complications and the role of endoscopic approach to manage these complications. Materials and Methods: Nineteen patients with indwelling JJ stent for a duration of more than 6 months were included in this study. Patients were assessed with X-ray KUB, USG KUB, blood urea, creatinine and DTPA renogram Ureteral stents are quite commonly used in patients that are suffering from urinary retention, have kidney stones that they are unable to pass, acute renal colic, a prolonged endoscopic procedure or aq situation where a second-look ureteroscopy has to be performed Ureteral stents are small tubes inserted into the ureter to treat or prevent a blockage that prevents the flow of urine from the kidney to the bladder. The most common reason for ureteral stents is the treatment of kidney stones. Below are the answers to some of the questions we receive about ureteral stents

All about ureteral stents

A ureteral stricture can block or narrow the ureter, making it difficult to pass urine from the affected kidney. To help open the passage and prevent it from narrowing, NYU Langone physicians can perform stenting. In this procedure, doctors place a small, hollow plastic or metal device called a stent into the ureter Ureteric stents, also known as ureteral stents, double J stents, JJ stents or retrograde ureteric stents, are urological catheters that have two J-shaped (curled) ends, where one is anchored in the renal pelvis and the other inside the bladder.. Stents are used for the free passage of urine from the kidney to the bladder, in adverse conditions such as postoperative urologic procedures, and. The authors concluded that metal mesh stents provide long-term decompression of the upper urinary tract in the presence of extrinsic ureteral obstruction only in select cases. M. F., Bahnassy. Objective To investigate the long-term outcome of treatment of ureteral stricture with shape-memory alloy net-like stent. Methods Nickel-titanium shape-memory alloy net-like stent was used to treat 9 patients with ureteral stricture, 4 males and 5 females, aged 41 (29-63), with the length of ureteral stricture of 1.0-4.0 cm, the etiology being radical operation for rectal carcinoma in 2 cases.


Metal stents have also been used over the last three decades including the Wallstent™, Resonance ® and Memokath™ stents. They have shown promising results particularly when long-term relief of ureteric obstruction is needed Ureter Reconstruction. The ureter is a long but thin tube that travels from the kidney to the bladder on each side of the body. Each tube is surrounded with muscle that tightens and relaxes, propelling the urine in an active process towards the bladder. Each ureter is generally 8-10 inches long. Indications a patient may need a ureter repair.

Numerous publications describe the management of stent encrustations, but few address long-term risks. The purpose of this study is to analyze the incidence of new chronic kidney disease attributed to retained ureteral stents in a large multi-institutional patient population Kidney stents, also called ureteral stents, are thin, flexible, hollow tubes placed into the ureter to bypass the obstruction and allow the passage of urine. One end of the stent opens into the kidney and the other end opens into the bladder. The stent is not permanent—the urologist removes it after the obstruction is resolved

The coating for ureteral stents has been designed for short-term implantation. The effect of the coating on the process of encrustation and PAP release by the dynamic in vitro model with artificial urine (AU) up to 30 days was evaluated. The influence of AU on the physical and chemical properties of ureteral stents was determined Ureteral Stent Set Universa® Double Pigtail 6 Fr. 24 cm Polyurethane.

There are curls on each end to stop the stent from moving. Stents are temporary and in some circumstances, a small length of string is attached to the lower part of the stent to facilitate removal A review of the currently available metallic stents and their role in the long-term management of ureteric strictures is presented. Materials used in the manufacture of indwelling urological. A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney.The length of the stents used in adult patients varies between 24 and 30 cm. Additionally, stents come in differing diameters or gauges, to fit different size ureters

The costs of managing MUO by polymer ureteric stent ranged from USD $4100 to $24 000 per patient per year. 2, 7 Previous cost effective analysis by López-Huertas et al comparing Resonance metallic stent vs polymer stent have shown that the metallic stent can provide a 43% cost reduction within a 12 month duration. 7 Yuen et al's study in a. The duration of ureteral stent treatment is dependent on the person's medical condition, it may be placed for a short duration or for long term treatment. However, ureteral stents may cause some side effects such as difficulty in physical activity Cauda, V. et al.

Partial ureteral lacerations or thermal injuries that are diagnosed during the operation can be managed by endoscopic placement of a ureteral stent (for four to six weeks). Laparoscopic suturing of the lacerated ureter also has been performed successfully used to provide temporary or long-term urinary drainage for patients with impassable ureteric strictures. This procedure has major disadvantages for long-term use because there is the need for regular changes, the catheters often get dislodged european urology 52 (2007) 193-198 available at www.sciencedirect.com journal homepage: www. Brief introduction. Memokath™ 051 Ureter is a non-allergenic metallic stent used to effectively treat ureteric stricture. The stent is typically inserted in 30-45 minutes under general or spinal anesthesia and can be inserted either retrograde or antegrade to be positioned across the stricture allowing urine to flow through the ureter The major benefit of stents is to prevent complications associated with ureteral obstruction as stone fragments pass down the ureter [3]. Indwelling stents are supposed to prevent pain, obstructive symptoms, and the need for secondary endoscopic procedures [4] Forgotten ureteral stent is not only disastrous for the patient but also fraught with serious medico-legal implications for the urologist. Herein, we present four cases of long-term retained part of ureteral stent with its varied presentation and subsequent management

Ureteral Stent Complications: Are they a Huge Health Risk

Metallic ureteric stents are a type of ureteric stent developed to offer improved symptomatic relief of obstruction when compared to polymeric (polyurethane) stents.They are often used in patients with chronic malignant ureteric obstructions who require placement of long-term ureteral stents to relieve the urinary obstruction and as a palliative measure to reduce pain and avoid major operation Ureteral stent placement is a procedure to open a blocked or narrow ureter. The ureter is the tube that carries urine from your kidney into your bladder. A stent is a thin hollow plastic tube used to hold your ureter open and allow urine to flow. The stent may stay in for several weeks. Long-term stents will stay in longer and need to be. A malignant ureteral obstruction (MUO) can be caused by a malignancy that compresses the ureter externally. MUO has been reported to be an indicator of poor prognosis, and the median life expectancy of patients with metastatic cancer that causes a ureteral obstruction is generally < 1 year [1,2,3].Immediate urinary diversion using a ureteral stent and the preservation of renal function are.

DESIGN Retrospective case series.. ANIMALS 44 dogs (57 ureters).. PROCEDURES Medical records of dogs that underwent ureteral stenting for treatment of benign ureteral obstruction between 2010 and 2013 were reviewed Figure 1 Ureteral stents are flexible tube-like devices with holes orthogonal to the length which allow for the passage of urine in case of ureteric obstruction. Pig tail ends in the stent help reducing migration of the stent and are located in the kidney and in the bladder. (A) A standard ureteral stent highlighting its key features (pig-tail ends and side-holes); (B) a cartoon of the urinary. Introduction. The long-term patency of a double J ureteral stent is known to be limited due to calcium salt deposition or stent displacement/fracture thus requiring regular removal or replacement (1-3).Although urologists traditionally remove and insert double J stents using a cystoscope (), fluoroscopy-guided antegrade or retrograde removal and replacement of a double J stent has gradually. Ureteral stents are widely used to ensure good urinary drainage and to relieve obstruction, pain and infection during urologic procedures. However, long‑term indwelling ureteral stents can cause various complications, such as encrustation, hematuria and infection. Here, the case of an 88‑year‑old man who had undergone simultaneous radical resection of sigmoid colon cancer and partial.
