OBJECTIVE To review published reports on arterio-ureteral fistula. METHOD Literature search. RESULTS Eighty cases were identified. Primary fistulas were mainly seen in combination with aortoiliac aneurysmal disease. Secondary fistulas were seen after pelvic cancer surgery, often with radiation, fibrosis and ureteral stenting or after vascular surgery with synthetic grafting. The dominating ...

PURPOSE To report the safety and efficacy of percutaneous nephrostomy and primary antegrade recanalization for treatment of iatrogenic ureteral strictures after gynecologic surgery. PATIENTS AND METHODS Ten women had symptoms suggestive of ureteral obstruction during the immediate postoperative period (5 days-1 week after surgery). Under analgesia and conscious sedation, standard percutaneous...

There are currently no plastic pancreatic duct stents that have been designed for endoscopic ultrasonography (EUS)-guided placement. This study prospectively evaluated the feasibility and efficacy of a new, single-pigtail, plastic stent. Eight patients with main pancreatic duct stricture or stenotic pancreatojejunostomy underwent EUS-guided placement of the pancreatic duct stent. The stent was ...

OBJECTIVE Laparoscopic ureteral surgery is becoming increasingly common; however, advanced laparoscopic skills are required due to the precise suturing involved. Because of the size of the ureter and need for careful mucosal apposition to prevent stricturing, there is less room for error than with larger lumens, as in pyeloplasty. We sought to identify whether the presence of a stent is benefic...

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. We read with great interest the study reported by Ra-bani (1). The author reported their experiences in endo-scopic management of forgotten ureteral stents with large burden stone encrustation. As the author stated, ureteral stents are widely used in urology practices. How...

Ureteral stents are commonly used in urology to provide urinary drainage of the upper tracts, particularly following treatment of urolithiasis. Stents are commonly plagued with infections and encrustation, particularly in stone-forming patients (Denstedt and Cadieux 2009). This involves a multistep process outlined in Figure 1. The first step is formation of a conditioning film comprised of uri...

PURPOSE The aim of this study was to evaluate whether long-term, postoperative ureteral stenting is necessary after ureteroscopic removal of stones (URS) during an uncomplicated surgical procedure. MATERIALS AND METHODS We prospectively examined 54 patients who underwent URS for lower ureteral stones from February 2010 to October 2010. Inclusion criteria were a stone less than 10 mm in diamet...

A seventy-one-year-old woman was hospitalized at our institution for a right-sided "renal colic" associated with an infectious background. Alithiasic ureterohydronephrosis was diagnosed by imaging. A urinary diversion was thus performed using a double J endoureteral stent. The etiologic assessment of the hydronephrosis showed the presence of a periureteral mass that caused extrinsic ureteral co...

OBJECTIVES To evaluate the efficacy of short-duration, open-ended ureteral catheter drainage as a replacement to indwelling stent, and to study the effect of tamsulosin on stent-induced pain and storage symptoms following uncomplicated ureteroscopic removal of stones. DESIGN Prospective randomised study. SETTING School of Medical Sciences and Research, Sharda University, Greater Noida, Indi...
