It is common to test medical devices in large animal studies that are or could also be used in humans. In this short report we describe the use of a ureteral J-stent for the evaluation of biodegradable tubular constructs for tissue reconstruction, and the regeneration of ureters in Saanen goats. Similarly to a previous study in pigs, the ureteral J-stent was blindly inserted until some resistan...

Ureteroarterial fistula (UAF) is a relatively rare condition with about 150 cases reported in the literature. Since it is a potentially life-threatening condition, a prompt diagnosis and treatment are crucial. We present here a rare, challenging case of UAF diagnosed after left nephrectomy, thus involving the ureteral stump. The difficult diagnosis and treatment by contemporary use of endovascu...

Purpose: The development of ureteral strictures is a complicated problem for patients who have had urinary reconstruction at the time of radical cystectomy. Management options range from conservative approaches with minimally invasive options such as balloon dilation and stent placement to the more invasive options with open or laparoscopic surgical repair. The purpose of this study was to revi...

Ureteroarterial fistulas (UAFs) are defined as an abnormal communication between one of the major arteries and the ureter. Urologists most frequently encounter iatrogenic fistulas occurring in patients with a history of pelvic extirpative surgery, chronic ureteral catheterization, and history of pelvic radiation. We present two cases of UAFs in patients with no history of prior radiation, who u...

Introduction: The incidence of urinary leakage is increased as nephron sparing surgery becomes more used for the management of small renal masses. We present an endourologic approach in a patient with a persistent urinary leak after partial nephrectomy by placing two synchronous ureteral stents to improve drainage and avoid further potential surgery. Patients and Method: A 39-year-old patient p...

INTRODUCTION We evaluated the effect of the presence of a double J stent on the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of lumbar ureteral stones. MATERIAL AND METHODS Between January 2007 and February 2012, we performed a retrospective cohort study. Forty-four patients were treated by ESWL for lumbar ureteral stones and included into two groups for the analy...

Objectives To evaluate the effectiveness and safety of Allium ™ ureteral stent as a curative treatment benign strictures. Materials methods We retrospectively reviewed electronic database two centers patients who underwent positioning for different types stenosis (benign or malignant). Between April 2017 May 2021, 151 were treated with strictures including malignant stenosis. In total, 83 them ...

OBJECTIVES Ureteral stenosis is a common complication after a kidney transplant. Treatment for ureteral stenosis ranges from interventional procedures to open surgery. The aim of this study is to present classification for ureteral stenosis and recommend the targeted strategy for effective treatment. MATERIALS AND METHODS Twelve cases of ureteral stenosis were diagnosed among 193 kidney trans...
