is Ureteral Stenting necessary after uncomplicated ureteroscopic lithotripsy a prospective randomized controlled trial
The Journal of Urology, 2002Co-Authors: Yung Tai Chen, Jun Chen, Waiyan Wong, Stephen Sheidei Yang, Chenghsing Hsieh, Chungcheng WangAbstract:Purpose: We conducted a prospective, randomized controlled study to investigate the advantages and disadvantages of Ureteral Stenting after ureteroscopic lithotripsy.Materials and Methods: A total of 60 patients who underwent ureteroscopic lithotripsy were equally randomized into a stented or a nonstented group. The inclusion criteria were stone 6 to 10 mm., absence of polyp or stricture in the ureter and no mucosal injury during ureteroscopy. The operation was performed with a 6Fr rigid ureteroscope without Ureteral dilation and stones were fragmented with a 1.9Fr electrohydraulic lithotriptor without extraction. A 7Fr double pigtail stent was placed in the stented group for 3 days after ureteroscopy. Urinalysis, plain x-ray and renosonography were performed before and after lithotripsy in each patient. Subjective symptoms and pain score were recorded on admission to the hospital and 3 days postoperatively.Results: The stone-free rate was 100% in each group and preoperative hydronephrosis equally resolve...

complete Ureteral stent encrustation managed with serial nephroscopy and laser lithotripsy
Urology, 2007Co-Authors: Joseph L Whetstone, Marc C Smaldone, Erin P Gibbons, Stephen V JackmanAbstract:Encrustation is a well-established complication of retained biomaterials in the urinary tract. Severe stent encrustation is a potentially serious complication of prolonged indwelling Ureteral Stenting often managed with open surgery when endoscopic techniques are unsuccessful. We present a case of a 2800-mm 2 stent encrustation managed with serial nephroscopy and laser lithotripsy.

Impact of Ureteral Stenting in ureteroscopy.
Current opinion in urology, 2016Co-Authors: Ben H. Chew, Christian SeitzAbstract:We review new therapies and biomaterials designed to reduce Ureteral stent symptoms in patients undergoing ureteroscopy. Pharmacologically, alpha blockers and antimuscarinics have been shown to have a synergistic effect and be more effective than either medication alone in reducing stent-related symptoms. PreStenting patients prior to ureterosocpy has been shown to be beneficial for patients with renal stones, offering a better stone-free rate and reduced complications, but not for Ureteral stones. Stenting after use of a Ureteral access sheath reduced complications and unscheduled emergency visits. Nonsteroidal anti-inflammatories have been shown to prevent pain after stent removal. Surveys showed that patients preferred to remove their own stents via dangle strings at home or undergo cystoscopic removal in the operating room with some type of anesthesia. New materials such as gel-based or biodegradable Ureteral stents are being developed to deal with stent-related pain, encrustation, and infection. Antirefluxing stents eliminate vesicoureteric reflux in patients during voiding and may reduce symptoms of back and flank pain. Ureteral stents are involved in many procedures in urology and particularly kidney stone treatments. Advances in materials and medications will help improve the patient experience for those who receive a Ureteral stent.

Impact of Ureteral Stenting prior to ureterorenoscopy on stone-free rates and complications.
World journal of urology, 2011Co-Authors: P. P. Lumma, P. Schneider, Arne Strauss, K. D. Plothe, Paul Thelen, Rolf-hermann Ringert, Hagen LoertzerAbstract:Objective To date, only few studies have evaluated the impact of Ureteral Stenting prior to ureterorenoscopy. This study is to clarify the role of preoperative Ureteral Stenting in the treatment for Ureteral stones.
