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...
OBJECTIVES To examine the feasibility of early laparoscopic ureteroneocystostomy for ureteral obstruction due to hysterectomy injury. METHODS We retrospectively reviewed a 10-y experience from 2 institutions in patients who underwent early (<30 d) or late (>30 d) laparoscopic ureteroneocystostomy for ureteral injury after hysterectomy. Evaluation of the surgery included the cause of the stric...
OBJECTIVE The purpose of the present study is to compare the standard bare metal stents (BMS) with the Paclitaxel-Drug Eluting Stent (DES) in the ureter of a pig model. MATERIALS AND METHODS We report on an experimental study with ten female pigs weighing between 25 and 30 kg. The stents were randomly placed in either the right or left ureter in each of 10 study animals, for a total of 20 ste...
there are occasional reports of using the appendix to replace sections of the ureters, and to our knowledge, only a couple of them were in the left side. we used the appendix as a ureteral substitute in two cases in technically difficult parts, the upper left ureter and the first part of the right ureter. follow-ups of8 years and 6 months in right and left side cases, respectively, are impressi...
INTRODUCTION The limitations of traditional ureteral stents in patients with deficiencies in ureteral drainage have resulted in frequent stent exchanges. The implementation of metallic stents was introduced to improve the patency rates of patients with chronic upper urinary tract obstruction, obviating the need for frequent stent exchanges. We report our clinical experiences with the use of met...
BACKGROUND Ureteral obstruction caused by extrinsic compression is often associated with intra-abdominal cancers. Internal drainage with ureteral stents is typically the first-line therapy to relieve such obstructions. Novel designs of ureteral stents made of different materials have been invented to achieve better drainage. In this study, we described the functional outcomes of a Resonance met...
PURPOSE To report the safety and efficacy of percutaneous nephrostomy and primary antegrade recanalization for treatment of iatrogenic ureteral strictures after gynecologic surgery. PATIENTS AND METHODS Ten women had symptoms suggestive of ureteral obstruction during the immediate postoperative period (5 days-1 week after surgery). Under analgesia and conscious sedation, standard percutaneous...
