Ureteric stent is encrusted with stone like material arrows especially in the bladder but also in the upper ureter. It is no longer functional i.e. side holes are blocked obstructing outflow, thus the collecting system is dilated. In summary, identification of encrustation of ureteral stents, one of the main complications of these materials, is possible with color-flow Doppler sonography in the presence of a twinkling artifact. The exact impact of sonographic follow-up on the urologic management of indwelling ureteral stents.
To present our experience and discuss the various endourological approaches for treating forgotten encrusted ureteral stents associated with stone formation.

Ureteral stents provide adequate drainage but when placed for long term, there is an increased risk of incrustation and stone formation.
Ureteral stents and nephrostomy tubes have been used extensively in urology. Attendant to their use are their associated morbidities, such as pain, infection, and encrustation. We review the literature on the subject of the encrusted stents and drainage catheters, discuss the risk factors for encrustation, and describe the endourologic. The removal of encrusted ureteral stents typically necessitates secondary treatment modalities, such as ureteroscopy, extracorporeal shock wave lithotripsy, or antegrade nephroscopy. We present a novel technique for the removal of minimally encrusted stents using a suture and a ureteral access sheath. Management of Forgotten Ureteral Stents One patient presented with a left retained ureteral stent for 9 years and right upper ureteric calculus, and a serum creatinine level of 5.4 mg%. Initially, a right ureteral stent was placed to normal-ize the renal parameters, and subsequently, a push back PCNL was done for the right ureteric calculus. 17/12/2018 · A kidney, ureter, and bladder radiograph KUB Fig. 1 and CT scan Fig. 2 showed the broken distal coil of the Double-J stent inside the urinary bladder with a 2 × 2 cm vesical stone with an encrusted Double-J stent along the entire length, and multiple stones in the right kidney.
As a result, the indications for ureteral stent placement have expanded significantly , Table 1 , 2–, 5. Ureteral stent placement is now considered a standard and indispensable urologic tool. As the technique has evolved, so has the design of the implanted device. 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.
• to allow the ureter to heal – either after injury to the ureter, major abdominal tummy surgery on the bladder or ureter, or after endoscopic surgery within the ureter itself Stents are designed to allow people to lead as normal a life as possible. However, they do have side-effects so. One study found that 9.2% of stents became encrusted when in place for less than 6 weeks, while 47.5% of stents that remained in place for 6 to 12 weeks were encrusted and 76.3% of stents were encrusted after 12 weeks El-Faqih et al, 1991. The length of time a stent remains in place is in fact the greatest risk factor for stent encrustation. T1 - Novel approach for removal of heavily encrusted ureteral stent. AU - Clark, Curtis. AU - Bylund, Jason. AU - Paszek, Matthew. AU - Lagrange, Chad. AU - Pais, Vernon M. PY - 2009/10. Y1 - 2009/10. N2 - We describe a novel approach for removal of a retained, heavily encrusted ureteral stent via combined laparoscopic cystolithotomy and. The stent that had encrusted by 1 month was in a pregnant woman with a ureteropelvic junction stone. She was treated with insertion of a second stent alongside the encrusted stent until she delivered, after which the stent was removed by rigid ureteroscopy. Five patients had more than one encrusted stent, with a total of 13 encrusted stents.
22/02/2019 · Background and Objectives: Remained or forgotten ureteral double-J stents may cause serious complications. Removing of an encrusted, forgotten stent can be challenging. We present our experience with heavily encrusted ureteral stents and discuss the endourologic treatment options as well as their effectivity. Materials and Methods. Encrusted ureteral stents are a challenging endourologic problem that may require multiple procedures. We performed a multi-institutional review of percutaneous nephrolithotomy PCNL as primary treatment for encrusted stents. Patients were identified who underwent percutaneous nephrolithotomyPCNL for treatment of an encrusted ureteral stent. Stents were in place for a mean of 10 months range 6 to 16. One patient had 2 retained stents in a single ureter. Stents were extracted using a holmium laser. The semirigid ureteroscope and/or flexible ureteroscope was advanced beside the retained ureteral stent and laser was used to fragment stone on and around the stent. and/or encrusted ureteral stents together with our single-center experience. Materials and methods: Fifty-four patients with forgotten double-J ureteral stents were treated in our center between January 2008 and March 2014. Encrustation and the related stone burdens.

Objectives: To present our experience in managing encrusted ureteral stents and to review the literature on the subject. Methods: A total of 22 patients with encrusted ureteral stent were treated in our department.

Ureteral stents are one of the most common devices used by urologists. They are placed with cystoscopic guidance in an operating room setting. Ureteral stents are used to relieve ureteral obstruction, promote ureteral healing following surgery, and assist with ureteral.Even though encrustation is seen frequently on retained stents, ureteral stents are rarely forgotten in clinical practice. A fortyone-year-old male patient was referred to our clinic in 2002 because of a forgotten JJ stent that encrusted and associated with a stone burden incidentally seen on the ultrasonography.

Ureteral Stent Exchange under Fluoroscopic Guidance Using the Crochet Hook Technique in Women. Urologia Internationalis, Vol. 88, No. 3. Ureteral stents are used to establish patency in a non-draining ureter, as they are commonly placed in etiologies such as ureteral obstruction and urological surgery. One complication that occurs with stent placement is the absence of follow-up to remove the device. This may be due to a myriad of reasons, including non-compliance and lack of.
