BACKGROUND: Urolithiasis is a global problem whose incidence is reported to be on the rise across the world. Previously, urolithiasis was reported as being rare among the indigenous African population but recent data suggest otherwise. This study reviewed the demographic and clinical characteristics of patients with urolithiasis seen at the Aga Khan University hospital Nairobi (AKUHN) as well as the chemical composition of the stones and the modalities of therapy used. METHODS: This was a retrospective study which utilized patients' clinical and laboratory records from 2013 to 2014...

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...

INTRODUCTION: During ureteroscopy (URS), ureteral dilation may be required to increase the likelihood of accessing the ureter to complete the procedure. Thus, we sought to assess the safety and efficacy of using Lubriglide sequential ureteral dilators(®) (Boston Scientific) to promote primary URS, without need for prestenting. PATIENTS AND METHODS: Retrospective review was performed of a consecutive series of patients undergoing primary URS by a single surgeon (N...

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...

AIM: To define treatment selection criteria for patients with bladder cancer combined with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Between 2006 and 2015, 1148 patients were treated for bladder cancer and 3368 patients for BPH. Among them, 258 (22.5%) patients had both bladder cancer and BPH. 113 (11.6%) patients had indications for surgical treatment of both diseases. In this group, 18 (13.5%) patients also had bladder stones. Only 2 (1.6%) patients had tumor invading the muscle wall, while the remaining patients had non-muscle invasive bladder cancer...

REVIEW
Tad Kroczak, Kenneth T Pace, Jason Y Lee
PURPOSE OF REVIEW: We set out to provide an overview of the most recent evidence for medical expulsive therapy (MET). Conflicting level 1 evidence for and against the use of MET has been published. RECENT FINDINGS: The largest double-blind randomized control trial (1110 patients) comparing placebo, tamsulosin, and nifedipine found no benefit for MET in preventing the need for secondary intervention. A recent meta-analysis of 55 randomized trials using alpha-blockers suggests that no benefit is seen with smaller ureteric calculi, but patients with larger ureteric calculi experience shorter times to stone passage, fewer episodes of pain, require less surgical intervention, and fewer hospital admissions...

BACKGROUND: Ureteric colic is the most common symptom of lithiasis. It is caused by the presence of stones accumulated in the renal papillae. These stones often migrate down the ureter, causing a ureteric colic, characterized by a severe pain in the lumbar region. The aim of this study was to compare the use of ketorolac and nifedipine vs. ketorolac and tamsulosin for the medical treatment of pain caused by stones in the lower ureter. METHODS: Longitudinal study of 150 patients of 21-years or older with stones in the lower third of the ureter...

Retrograde ureteric stone migration is an extremely rare phenomenon with only one previously reported case in the literature. We report on a case of upward spontaneous migration of a ureteric stone in a 39-year-old male military trainer in Saudi Arabia who was diagnosed with upper left ureteric stone based on non-contrast spiral computerized tomography kidney ureter bladder (CT-KUB) scan. The plan was to treat the patient conservatively with alpha blockers and oral hydration. Two weeks after treatment started, repeated CT-KUB scan revealed an upward migration of the stone to the left renal calyx...
