OBJECTIVES: To describe the technique and report our first experience of robotic-assisted renal transplantation (RART) with more than one year follow up. PATIENTS AND METHODS: In our center the first case of RART was realized in October 2013 with a cadaveric graft. We used the combined extra- and intraperitoneal robot assisted laparoscopic route with extraperitoneal positioning of the graft and intraperitoneal transplantation. The patient was placed in the supine position with arms along the body; the robot came from the right inferior part of the patient...

Ureterocalicostomy is usually a salvage procedure for recurrent pelvi-ureteric junction (PUJ) stricture or upper ureteric injury. It requires meticulous dissection of the upper ureter, and lower pole nephrectomy is considered an essential step to achieve a wide funneled and dependent ureterocaliceal anastomosis. We, hereby, highlight the importance of guillotine lower pole nephrectomy through a case report of recurrent PUJ stricture managed with ureterocalicostomy that failed due to the omission of lower pole nephrectomy...

Ureteral metastasis of renal cell carcinoma (RCC) is rare and usually confined to the ipsilateral ureter. In literature, about 50 cases have been reported so far. Of these, only 14 metastasized metachronously to the contralateral ureter.A seventy-one-year-old man was hospitalized with recurrent painless severe haematuria. Seven years previously, he had undergone radical nephrectomy of the right kidney due to a clearcell renal cell carcinoma (cRCC), Fuhrman grad 2. Intravenous urography and a retrograde ureterogram revealed a filling defect (25 mm) in the left distal ureter, which we expected to be an urothelial carcinoma...

Background: Schistosomiasis is rare in western countries, but remains a potentially serious disease. It is known to result in severe urogenital complications; prompt diagnosis can therefore significantly affect outcomes. Case Presentation: We report the case of a 41-year-old male with pleuritic chest pain and visible hematuria who had emigrated from Zimbabwe to the United Kingdom 20 years previously. CT imaging revealed a hydronephrotic right pelvicaliceal system, with a dilated ureter to its distal portion...

INTRODUCTION: It is generally advised to have a safety guidewire (SGW) present during ureteroscopy (URS) to manage possible complications. However, it increases the strenght needed to insert and retract the endoscope during the procedure, and, currently, there is a lack of solid data supporting the need for SGW in all procedures. We reviewed the literature about SGW utilization during URS. METHOD: A review of the literature was conducted through April 2017 using PubMed, Ovid, and The Cochrane Library databases to identify relevant studies...

BACKGROUND: Biliary complications continue to be the "Achilles heel" of living-donor liver transplantation (LDLT). The use of biliary stents in LDLT to reduce biliary complications is a controversial issue. We performed a randomized trial to study the impact of intraductal biliary stents on postoperative biliary complications after LDLT. STUDY DESIGN: Of the 94 LDLTs that were performed during a period of 16 months, ABO-incompatible transplants, left lobe grafts, 3 or more bile ducts on the graft, and those requiring bilioenteric drainage were excluded...

REVIEW
Mohamed A Elkoushy, Sero Andonian
Patients presenting with nephrolithiasis often undergo repeated imaging studies before, during, and after management. Considering the significant risk of stone recurrence in primary stone-formers, repeated imaging studies are not uncommon. Cumulative effects of ionizing radiation exposure from various imaging studies could potentially increase the risk for developing cataracts and solid malignancies in urolithiasis patients. Therefore, practitioners planning or performing imaging studies with ionizing radiation are compelled to keep radiation exposure to humans and the environment as low as possible, thus strictly adhering to the ALARA (As Low as Reasonably Achievable) principles...

Gilad Amiel, Zaher Bahouth, Boaz Moskovitz, Sarel Halachmi, Ofer Nativ
Stents are widely use in endoscopic urological procedures. One of the most important indications is the treatment of urinary tract strictures. Allium™ Medical has introduced several types of stents for the treatment of different types of urinary tract strictures, based on anatomic location. All the stents are made of nitinol and coated with a co-polymer that reduces encrustations. These stents are self-expandable and have a large caliber and a high radial force. They have different shapes, designed especially for the treatment of each type of stricture...
