INTRODUCTION: Use of a ureteral access sheath (UAS) within flexible ureteroscopy (fURS) for the management of kidney and ureteral stones has shown improvements in its effectiveness, but it is also associated with increased risk of ureteral injury. Use of ureteral stent (US) after fURS is recommended by some authors, because of its role in reducing postoperative pain and preventing complications. Our objective is to determine if postoperative stenting is necessary in pre-stented patients that underwent fURS using UAS...

A 41-year-old male presented at Emergency Department (ED) with right flank pain associated with hematuria for 3 days. Patient had a previous history of nephrolithiasis. The physical examination and blood tests were normal. Urine analyses showed haematuria > 1.000.000/μL. After clinical evaluation, a computer tomography (CT) showed right ureteral dilata¬tion caused by a 5 mm proximal stone and a distal intraluminal mass of 8 cm in length. In this setting, an ureteroscopic biopsy was performed and revealed a large polypoid lesion histologically suggestive of fibroepithelial polyp...

OBJECTIVE: To investigate the efficacy of plain radiography and ultrasonography each as the sole imaging tool as well as combined, for detecting renal stones using unenhanced computed tomography as a standard reference. Ultrasonography and plain radiography of the kidneys, ureters, and bladder are often used for urinary tract stone detection, but the effectiveness of each method used alone, or the two methods used together, remains controversial. MATERIALS AND METHODS: From January 2012 to September 2014, 822 patients underwent plain radiography, ultrasonography, and unenhanced computed tomography on the same day...

INTRODUCTION: The treatment of large renal stones (≥1 cm) in paediatric patients is challenging. The usual treatment options include percutaneous nephrolithotomy (PCNL) or shockwave lithotripsy (SWL). There is a rise in the use of ureteroscopy and laser stone fragmentation (URSL) for paediatric stones; however, outcomes of treatment for large renal stones in this age group are still largely unknown. OBJECTIVE: To investigate the outcome of URSL for large paediatric renal stones ≥1 cm treated at the present institution over the last 5 years...

Impacted stones frequently cause changes in the ureter, including edema of the ureteral wall, stone embedding in the ureteral mucosa or ureteral bending, which often preclude spontaneous passing of the stone and increase the risk of complications during surgery. When stone impaction is suspected preoperatively, management should be adapted accordingly. However, surgical treatment strategies remain controversial in pediatric patients because of the scarcity of cases reported. We describe the case of a 2-year-old girl with a right impacted ureteral stone who presented with gross hematuria and pyuria, but no metabolic risk factors or hematological abnormalities...

Sonography is a convenient, non-invasive diagnostic modality in small ruminants, often used in reproductive management, internal medicine, and surgery. Pregnancy diagnostics and imaging anatomy and pathology of organs, such as neoplasia, are major applications. Urolithiasis is one of the most common causes of death in male sheep and goats, for which sonography is the diagnostic modality of choice. Although ultrasound-imaging techniques for kidneys, ureters, and urinary bladder in small ruminants have been described previously, this study focuses on reporting the imaging technique of the extra-pelvic portion of the urethra, as nearly all the cases of obstructive urolithiasis result from urinary stones in this part...

Expert panels of AUA and EAU defined highly effective approaches to surgical treatment of ureterolithiasis and recommended extracorporeal and contact lithotripsy as the main options. Therapeutic strategy for ureteral stones measuring less than 10 mm is clearly defined and supported by the Russian Society of Urology. At the same time, the views of researchers on the management of large ureteral stones vary. This literature review provides information on the results of extracorporeal shock-wave lithotripsy and contact ureterolithotripsy of large stones located in various parts of the ureter...
