BACKGROUND AND PURPOSE Ureteroscopy is nowadays one of the techniques most widely used for upper urinary- tract pathology. Our goal is to describe its complications in a large series of patients. PATIENTS AND METHODS Between June 1994 and February 2005, 2436 patients aged 5 to 87 years underwent retrograde ureteroscopy (2735 procedures) under video and fluoroscopic assistance. We used semirig...

We present a case of 52 year old male with an acute renal failure that took place 4 days after open transabdominal surgery repair of infrarenal abdominal aneurysm along with aneurysm of left common iliac artery and dilatation of left external iliac artery. Patient was subjected to 13 hemodialysis treatments that resulted in satisfactory recovery of renal function. One month after aneurysm repai...

PURPOSE Nephrostomy tube insertion and/or a ureteral stent placement is advised when pelvi-calyceal perforations are encountered during percutaneous nephrolithotomy (PNL) nevertheless totally tubeless PNL is a possible exit strategy in percutaneous renal surgery therefore case series on the short term clinical outcomes of noninvasive management of iatrogenic pelvicalyceal perforations encounter...

BACKGROUND AND AIM The objective of this study was to establish a rat model to develop hypertrophic fibrosis for subsequent safe application of ureteral stents in order to investigate new treatment options for ureteral strictures. MATERIALS AND METHODS Thirty-two male Sprague-Dawley rats were used. Group 1: Sham surgery; group 2: surgery with uretero-ureteral anastomosis and stenting. Histopa...

INTRODUCTION Use of a ureteral access sheath (UAS) within flexible ureteroscopy (fURS) for the management of kidney and ureteral stones has shown improvements in its effectiveness, but it is also associated with increased risk of ureteral injury. Use of ureteral stent (US) after fURS is recommended by some authors, because of its role in reducing postoperative pain and preventing complications....

OBJECTIVE Ureteral obstruction is one of the complications of testicular tumor with retroperitoneal lymph node metastasis that requires ureteral stenting for management. We elucidated the clinical courses of ureteral obstructions and changes in renal functions in patients with indwelling ureteral stenting. METHODS The medical records of 56 patients who were treated for metastatic testicular t...

We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevat...

Sutureless end to end ureteral anastomoses was successfully constructed in acute and chronic experiments. A photothermal sensitive hydrolyzable (PSH) albumin stent played roles as solder and intraluminal supporter to adhesion and position the anastomosed ureter by end to end fashion. The anastomosis seam was lased with 810 nm diode laser energy supplied through hand-held 600 mm noncontact optic...
