Late complications of ureteral stents are frequent, and longer indwelling times are associated with an increased frequency of complications. Although there are reports of various complications of long-term indwelling ureteral stents, a renocolic fistula secondary to a perinephric abscess resulting from an indwelling ureteral stent has not been reported. Here, we present a fatal case of a renoco...

PURPOSE Previous reports suggest a high success rate for retrograde ureteral stenting for intrinsic ureteral obstruction, but few preoperative predictors of success have been offered. We reviewed our experience to look for factors that suggest failure of stents for intrinsic ureteral obstruction. MATERIALS AND METHODS We retrospectively reviewed the outcome of retrograde ureteral stent placem...

BACKGROUND AND PURPOSE Ureteral stents are widely used in patients with urologic disorders. This review critically evaluates the recent literature, providing an update on advances in the development and design of stents. METHODS A thorough MEDLINE and PubMed literature search on ureteral stents was performed, and all pertinent articles were reviewed in detail. This review was formulated on th...

BACKGROUND The most important surgical complications of renal transplantation are stenosis and obstruction of the ureterovesical anastomosis. Routine use of ureteral stents can prevent this complication, but the optimal time for ureteral stent use is still controversial. OBJECTIVES The purpose of this study is to compare the benefits and complications of early and delayed stent removal after ...

OBJECTIVES To analyzed the therapeutic results for patients with overlooked iatrogenic ureteral injuries after gynecological surgery, treated at the department since 1990. Before the era of endourology, ureteral injuries were operated on immediately after making a diagnosis. This approach was changed after the popularization of percutaneous nephrostomy (PN) and ureteral stenting using a JJ sten...

The incidence of post-renal transplantation ureteral stenosis ranges from 2%-12%. Because the role of self-expanding ureteral metallic stents for its treatment has been scarcely reported, the aim of this study was to evaluate the efficacy of Nitinol stents. Eleven ureteral stenoses in patients with chronic graft dysfunction (8 cases) or high surgical risk (3 cases) were treated by antegrade per...

OBJECTIVES Ureteral double-J stents are known to migrate proximally and distally within the urinary tract, while perforation and stent displacement are uncommon. Possible mechanisms of displacement are either original malpositioning with ureteral perforation or subsequent fistula and erosion of the excretory system, due to infection or long permanence of the device. We present the unique case o...

OBJECTIVE The commonest indications for ureteral stent placement are: obstructive nephrolithiasis, renoureteral surgery, urologic oncology, endourology and extrinsic ureteral compression. METHODS We report the case of a 77-year-old male patient with a DJ ureteral catheter placed for an 8-month period and history of nephrolithiasis; the stent showed a 60 mm x 30 mm calcification on its distal ...

background ureteral stents are widely used in many urologic practices. however, stents can cause significant complications including migration, fragmentation, and encrustation and it may possibly be forgotten. successful management of a retained, encrusted stent requires combined endourological approaches. objectives to present our experience with the approaches for treating forgotten ureteral ...

A knotted ureteral stent is an extremely rare condition, with fewer than 20 cases reported in the literature; however, it is difficult to treat. We report a case in which a folded Terumo guidewire was successfully used to remove a knotted stent percutaneously without anesthesia. We also review the current literature on predisposing factors and management strategies for knotted ureteral stents.
