The incidence of post-renal transplantation ureteral stenosis ranges from 2%-12%. Because the role of self-expanding ureteral metallic stents for its treatment has been scarcely reported, the aim of this study was to evaluate the efficacy of Nitinol stents. Eleven ureteral stenoses in patients with chronic graft dysfunction (8 cases) or high surgical risk (3 cases) were treated by antegrade per...

PURPOSE We report our experience with auto-expandable metallic stents for treating ureteropelvic junction obstruction. MATERIALS AND METHODS We treated 4 patients with a mean age of 45 years who had ureteropelvic junction obstruction with placement of a self-expandable intraureteral metallic stent (Wallstent, Schneider, Zurich, Switzerland). All patients presented with recurrent ureteropelvic...

Ureteral stents are commonly used following urological procedures to maintain ureteral patency. However, alongside the benefits of the device, indwelling stents frequently cause significant patient discomfort (pain, urgency, frequency) and can become encrusted and infected. The importance of these sequelae is that they are not only bothersome to the patient but can lead to significant morbidity...

Urology has traditionally been a technically driven specialty. Minimally invasive surgical procedures aim to reduce collateral surgical damage while optimizing functional and oncological results. Improvement of magnification, 3D imaging, articulated instruments, depth perception, and precise motor control are prerequisites to achieve these goals. Robotic technology has overcome most of these po...

Abstract Background Malignant ureteral obstruction caused by extrinsic compression of a primary malignant tumour or metastatic disease is an indicator poor prognosis with median life expectancy about one year. We examined clinical outcomes following Resonance Metallic Ureteral Stent (Cook Medical, Bloomington, IN) placement in patients obstruction. Methods This was prospective study who underwe...

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Ureteral stents are being used more commonly in the daily urological practice. They are functionally used to re-establish or maintain the patency of the ureter and are used to relieve ureteral obstruction, promote ureteral healing following surgery, and to assist with uret...

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 of 8 years and 6 months in right and left side cases, respectively, are impress...
