Ureteral-iliac artery fistula (UIAF) is a rare life threatening cause of hematuria. The increasing frequency is attributed to increasing use of ureteral stents. A 68-year-old female presented with gross hematuria. She had prior low anterior resection for rectal cancer and a retained ureteral stent. CT abdomen and pelvis showed a large recurrent pelvic mass and a retained stent. The patient unde...

Background: The use of ureteroscopy in the management of urolithiasis is well established. Ureteral avulsion is a rare but challenging complication of the procedure. Postureteral injury strictures are a common result of such injuries and are typically managed with reconstructive surgery or endoscopically with polymer stent. This case represents the first effective management of ureteral avulsio...

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 complication...

Double-j (DJ) ureteral stenting is a very common procedure performed after various endourological procedures. Although several complications due to DJ stent insertion were revealed, only three cases of renal parenchymal perforation have been reported to date. We present a case of a 35-year-old woman who had perforation of renal parenchyma without perirenal hematoma following insertion of DJ ure...

BACKGROUND AND PURPOSE Ureteral strictures (US) can be a recurrent chronic illness that leads to severe side effects and poor quality of life. Several options to treat US exist, including repeated dilations, stents, minimally invasive reconstructive surgeries, and urinary diversion or nephrectomy. Placement of an ureteral stent is a good minimally invasive option but has major limitations, such...

Ureteral stents have been used for maintaining luminal patency in ureteral obstruction, including cases of malignant ureteral obstruction due to pelvic malignancy, since the late 1970s (1). Due to migration, encrustation, obstruction, and infection, these ureteral stents have to be removed or exchanged within 4-6 months of the initial placement (2-4). Recently, new optional stents such as metal...

The ureter is possibly the least studied and most poorly understood organ of the urinary tract. The pathophysiologic basis underlying the use of α-blockers to improve ureteral stone passage or to treat ureteral stent symptoms is poorly understood. This, in part, may explain why clinical studies of medical expulsive therapy for ureteral stone passage are fraught with conflicting data. Methods to...

Double-J (DJ) stents are the main tools used in urological practice for prevention and treatment of obstruction. Stenting is also mandatory after complicated ureteroscopy or TUL (Transureteral Lithotripsy). Known complications are upper migration of DJ stents into the kidney and lower migration to the bladder. In a man with an impacted right lower ureteral stone, a DJ stent was placed because t...

BACKGROUND Ureteral stent removal using an extraction string is advantageous because it can obviate an invasive cystoscopy, but there is a paucity of data on how patients feel about it, and how bothersome or beneficial it is. We performed this study to evaluate patients' preference for stent removal using an extraction string and which parameters could affect it. METHODS In total, 114 consecu...

R organ injury, especially ureteral injury, is a rare complication associated with surgical repair of lumbar disc hernia (LDH).(1-3) A 44-year-old male patient was admitted to the urology department with a history of left flank pain, fever, and intermittent hematuria. He had a history of repeat surgical repair of an LDH at the same level 1 month previously. Ultrasound examination revealed a mul...
