Clinical case description: We report the of a patient who underwent double-pigtail ureteral stent (DPS) retrograde placement, following complicated right renal colic. After two days with persisting pain and hematuria, CT-Scan revealed proximal pigtail misplacement into inferior vena cava (IVC). In multidisciplinary approach, an endourological removal was performed, pulling distal loop cystoscop...

hydronephrosis was not demonstrable by ultrasonoIntroduction graphy, we elected not to perform a transplant puncture for antegrade pyelography or drainage tube Urological complications are the most common type insertion. The patient underwent an MRT of the of post-transplant surgical problems [1]. Delay in transplant and this clearly demonstrated a distal transaccurate diagnosis and an inapprop...

PURPOSE To determine factors affecting patients' discomfort during the period self-retaining ureteral stents are in place. PATIENTS AND METHODS Between April 2001 and May 2003, 58 male and 42 female patients underwent temporary double-pigtail stenting. The indications were endopyelotomy in 39 patients, ureteroscopy in 32, laparoscopic pyeloplasty in 18, and endoureterotomy in 11. The stents w...

background the most important surgical complications of renal transplantation are stenosis and obstruction of anastomosis of the ureter to the bladder. hence, routine use of ureteral stents to prevent such complications seems logical; however, the optimal time to remove the ureteral stent is still controversial. objectives the purpose of this study was to compare the benefits and complications ...

PURPOSE Ureteral patency in malignant ureteral obstruction cases is a therapeutic challenge. We report our long-term experience with palliative treatment for extrinsic malignant ureteral obstruction with percutaneous placement of metal mesh stents. MATERIALS AND METHODS From January 1996 to December 2005, 90 patients with a mean age of 59 years (range 35 to 80) with ureteral obstruction due t...

A 57-year-old man underwent endoscopic retrograde cholangiopancreatography (ERCP) for multiple bile duct and gallbladder stones. During the ERCP, we attempted to insert a prophylactic 5-Fr, single pigtail pancreatic stent (Cook Endoscopy, Winston-Salem, North Carolina, United States) because biliary cannulation is difficult and the pancreatic duct is frequently cannulated unintentionally; howev...

conclusions we can remove the ureteral stent earlier after kidney transplantation with no increase in the prevalence of surgical complications. patients and methods all patients who underwent kidney transplantation from may 2011 until march 2012 in modarres hospital were included in this study. we classified the patients into three groups, based on time of stent removal (10, 20, and 30 days aft...

results a total of 529 patients underwent kidney transplant surgery in our center. urologic complications among the three groups consisting of hydronephrosis, urinoma and collection did not have statistically significant differences. conclusions ureteral stent can be picked up with no increased risk of urologic complications at shorter intervals after the kidney transplantation surgery. patient...
