The objective of this study is to assess the efficacy of adjunctive silodosin therapy in improving the success rate of semi-rigid ureteroscopy for removing ureteral stones. Prospective randomised controlled clinical trial performed between July 2016 and September 2016. All the patients underwent ureteroscopic holmium lithotripsy with a YAG laser. The patients were randomised into one of three groups: those who did not use an alpha-1 blocker (AB) (Group 1, n = 50), those who used an AB for one day (Group 2, n = 50), and those who used an AB for three days (Group 3, n = 47)...

Background: Nephron-sparing surgery has been shown to achieve oncological results equivalent to those of radical nephrectomy in patients with compromised renal function who have renal tumors <4 cm. However, technical difficulties and potential surgical complications remain challenges to the surgeon. Various factors, such as tumor size and location, collecting system invasion, and patient's expectations, are major concerns that may affect the feasibility of performing an effective partial nephrectomy. We report a patient with renal cell carcinoma who underwent open partial nephrectomy and suffered from complications of perirenal abscess because of stone migration, obstruction, and subsequence urine leakage...

Introduction: Flexible ureteroscopy (fURS) is an endoscopic procedure for the minimally invasive treatment of ureteral and renal calculi. Due to improvements in technique and ureteroscopic instrumentation over the past two decades, complications associated with URS are infrequent. However, in the event of an unexpected device malfunction or failure, the operating surgeon must employ prompt, resolute decision-making to resolve any intraoperative complications and avoid significant injury to the kidney or ureter...

RATIONALE: In patients with bilateral ureteral obstruction, the serum creatinine levels are often elevated, sometimes causing postrenal acute kidney injury (AKI). In contrast, those with unilateral ureteral obstruction present normal serum creatinine levels, as long as their contralateral kidneys are preserved intact. However, the unilateral obstruction of the ureter could affect the renal function, as it humorally influences the renal hemodynamics. PATIENT CONCERNS: A 66-year-old man with a past medical history of hypertension and diabetes mellitus came to our outpatient clinic because of right abdominal dullness...

INTRODUCTION AND OBJECTIVES: Ureteral stent symptoms are experienced by the majority of patients with ureteral stents. No one stent or technology has shown a clear advantage.  The Helical<sup>TM</sup> stent, a spirally cut stent made of proprietary Percuflex<sup>TM</sup> material was designed to conform to the shape of the ureter and better accommodate patient movement.  We prospectively sought to compare unscheduled visits, analgesic use and pain scores in patients who received a Percuflex Helical ureteral stent following ureteroscopy compared to a historical control group...

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 elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus...

OBJECTIVE: To compare the measured stone burden recorded between urologists and radiologists, and examine how these differences could potentially impact stone management. As current urologic stone surgery guideline recommendations are based on stone size, accurate stone measurements are crucial to direct appropriate treatment. This study investigated the discrepant interpretation that often exists between urologic surgeons and radiologists' estimation of patient urinary stone burden. MATERIALS AND METHODS: From November 2015 through August 2016, new patients prospectively enrolled into the Registry for Stones of the Kidney and Ureter (ReSKU™) were included if they had computed tomography images available and an accompanying official radiologic report at the time of their urologist provider visit...

Shows the current real time terminology and variants of systematization and grading of complications of contact ureteral lithotripsy (CULT). Research papers related to complications of CULT published over the last three decades were analyzed. Currently there is no clear terminology, classification, systematization and grading of CULT complications. The terms used are deficient because they do not adequately characterize specific complications of CULT. For example, some researchers define a complete ureteral avulsion as a defect at two levels, but others interpret it as a defect of the ureter at only one level...

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...

Urolithiasis is a well-known and common late complication in patients with urinary diversion. Patients without urinary diversion lead to symptoms such as hematuria and ureteral colic, whereas stones in patients with urinary diversion tend to be asymptomatic and are often diagnosed incidentally during staging examinations of oncologic diseases. We report the case of a 64-year-old male patient with a lower pole kidney stone and a stone in the ileal ureter substitution. He presented with diffuse abdominal and left-sided flank pain...
