OBJECTIVE To evaluate predictive factors for retrograde ureteral stent failure in patients with non-urological malignant ureteral obstruction. MATERIALS AND METHODS Between 2005 and 2014, medical records of 284 malignant ureteral obstruction patients with 712 retrograde ureteral stent trials including 63 (22.2%) having bilateral malignant ureteral obstruction were retrospectively reviewed. Re...

Usage of ureteral DJ stent is very common in urology practise. There are some complications according to the increased usage of ureteral DJ stent in the literature. Stent fragmentation is a rare complication of ureteral DJ stent. In this study we present a 53-year-old male patient who had previous stone surgery and a ureteral DJ stent applied to our polyclinic with complaint of 3-months-long ri...

Introduction. An isolated renal pelvis rupture is a rare type of blunt trauma that can occur mostly in patients with pre-existing hydronephrosis due to different causes. We presented patient the misplacement percutaneous nephrostomy tube during treatment caused by post-irradiation ureteral stricture. Case report. A 36-year-old woman was referred our institution her gynaecologist for retroperito...

A 72-year-old man with jaundice by ampullary adenocarci-noma was treated at our hospital. For biliary decompression, a transpapillary, fully covered, self-expandable metal stent (FCSEMS) was deployed. Four days later, the patient devel-oped acute cholangitis. Endoscopic carbon dioxide cholan-giography revealed kinking of the common bile duct above the proximal end of the FCSEMS. A 7-F double-pi...

Ureteral stent exchange is usually performed under both fluoroscopic and cystoscopic guidance. We experienced two cases with retrograde placement of metallic ureteral stent via urethra under fluoroscopic guidance. When patients with double-J ureteral stent (DJUS)have symptom and want to change DJUS to metallic stent, fluoroscopic guided transurethral placement of ureteral metallic stent is a go...

Endoscopic transpapillary gallbladder stenting is currently indicated to treat acute cholecystitis, and a double-pigtail plastic stent is usually placed [1–3]. No case of cholecystocolonic fistula caused by endoscopic transpapillary gallbladder stenting has been reported. An 87-year-old man was admitted to our hospital for the treatment of right hypochondralgia. Computed tomography revealed gal...

The effectiveness of pancreatic stents for prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis is widely recognized [1]. However, proximal migration of a pancreatic stent is occasionally encountered, potentially necessitating surgical intervention [2,3]. A gooseneck snare (Amplatz GooseNeck Microsnare Kit; Covidien, Irvine, California, USA), which was originall...

From July, 1987 to Oct, 1989 , 104 patients underwent 111 transurethral ureteroscopy procedures at the Air Force Medical Center. All intramural ureters were dilated by flexible metal dilators. The overall success rate for ureteral stone removal was 95.8 per cent. Ureteroscopy was done for evaluation of gross hematuria, strictures, ureteral stent, and ureteral and pyelocalyceal tumors. The ...

Accurate evaluation of stent encrustation patterns, such as volume distribution, from different patient groups are valuable for clinical management and the development better stents. This study quantitatively compares patterns stone kidney transplant patients. Twenty-seven double-J ureteral stents were collected patients with disease or who underwent transplantation. Encrustations on samples qu...
