Subureteral endoscopic injection is a safe and effective treatment for vesicoureteral reflux (VUR). Dextranomer/hyaluronic acid (Dx/HA) is the most commonly used bulking agent for the treatment of VUR. We report a confusing radiographic finding of calcified Dx/HA injection initially simulates distal ureteral stone in a female patient who has intermittent lumbar pain. Calcification of Dx/HA implants may mimic distal ureteral calculi; therefore, urologists should be aware of the potentially confusing radiographic images...

Background: Urinary tract stones is one of the most frequent medical emergencies which leads to life-threatening complications, namely obstructive uropathy as well as renal failure in some situations. Previously, bilateral stones were treated with either open surgery or percutaneous nephrolithotomy (PCNL). However, these treatment options were associated with lengthy operation time, need for more anesthesia, further bleeding, and long hospitalization. Therefore, much effort has been made to treat both sides simultaneously...

Use of α-blockers for medical expulsive therapy (MET) has been the subject of huge debate in Urology. Moreover, there have been a number of randomised controlled trials (RCTs) with differing results. We conducted a systematic review and meta-analysis of RCTs investigating the efficacy α-blockers for MET. This review confirms there is a role for α-blockers in medical expulsive therapy for ureteric stones specifically in stones >5mm and distal ureteric stones, which is associated with improved stone expulsion...

BACKGROUND: Ureteral colic is a common reason for patients to seek medical care. Alpha-blockers are commonly used to improve stone passage through so-called medical expulsive therapy (MET), but their effectiveness remains controversial. This is an update of a 2014 Cochrane review; since that time, several large randomised controlled trials (RCTs) have been reported, making this update relevant. OBJECTIVES: To assess effects of alpha-blockers compared with standard therapy for ureteral stones 1 cm or smaller confirmed by imaging in adult patients presenting with symptoms of ureteral stone disease...

CLINICIAN'S CAPSULE What is known about the topic? Most ureteral stones pass spontaneously, but intervention is an option. No trials have compared conservative vs. interventional treatment. What did this study ask? We compared 60-day outcomes for ED patients with ureteral colic in Calgary and Vancouver. What did this study find? Index intervention rate was seven-fold higher in Calgary. Calgary patients had more subsequent ED revisits and hospitalizations. Adverse outcomes were associated with intervention for small stones and with non-intervention for large stones...

Acute flank pain from suspected urolithiasis is a common presenting complaint in the Emergency Department. Multiple computed tomography (CT) has traditionally been the standard imaging modality used to diagnose obstructive kidney stones, however point of care ultrasound (PoCUS) can play an important role in the diagnostic algorithm and risk stratification of acute flank pain. Here, we present the case of a 29-year-old female with suspected urolithiasis, who underwent PoCUS that revealed right-sided hydronephrosis and normal left kidney, bladder, and aorta...

BACKGROUND Urine solute supersaturation leads to the formation of urinary tract caliceal stones. Many parameters can be involved in the supersaturation of solutes in urine, such as pH. Uric acid has pKa ≤5.5, and it is solubilized at pH ≥5.5. The objective of the study was to evaluate the effects of potassium citrate and lemonade supplementation in pediatric patients with urolithiasis. MATERIAL AND METHODS A total of 126 children who had lower ureteral stones calculi and fragments with severe colic pain participated in this cross-over study...

Introduction Ureteral duplication is the most common ureteral anomaly, occurring in 0.6-0.7% of the population. Our objective was to compare urolithiasis treatment outcomes in patients with and without ureteral duplication. Methods Patients with ureteral duplication who underwent ureteroscopy (URS) were identified in a stone registry at a high volume, tertiary care center from 1998 to 2015. Preoperative, intraoperative, and postoperative data were collected retrospectively. A 1:1 control cohort of patients without duplication was identified, matched by stone location and size, as well as age, BMI and gender...

Owing to the fragile kidney and relative small collecting system of pediatric patients, urologists were always reluctant to treat pediatric urolithiasis with PCNL. Here we conduct a study to assess the effectiveness and safety of pediatric patients with renal calculi <6 years.A total of 88 pediatric patients (99 kidney units) <6 years underwent the ultrasound (US)-guided minimally invasive percutaneous nephrolithotomy in our institute from March 2006 to April 2016. The mean age was 30.9 months (range, 7-72 months)...

INTRODUCTION: Successful surgical therapy for pediatric upper urinary tract calculi (UUTC) minimizes the need for repeat surgical interventions. However, staged procedures, whether planned or unplanned, are sometimes necessary. We assessed predictors of repeat intervention for children with UUTC using a nationwide administrative dataset. METHODS: Using the Pediatric Health Information System (PHIS) dataset, we assessed children with UUTC undergoing shock wave lithotripsy (SWL) or ureteroscopy (URS) for an index stone from January 2010 to June 2015...

INTRODUCTION: Ureterocele is a cystic dilatation of the lower part of the ureter. It is a congenital anomaly that is associated with other anomalies such as a duplicated system, and other diseases. It poses a great challenge owing to its numerous types and clinical presentations. Its incidence is 1 in every 4000 individuals. One of its presentations in the adult population is the presence of a stone, usually a solitary stone, inside the ureterocele. CASE PRESENTATION: We are reporting a case of an adult ureterocele complicated by a large calculus; managed endoscopically with transurethral deroofing of the ureterocele followed by cystolitholapaxy...

OBJECTIVES: The most important treatment strategy for obstructive nephropathy is to protect renal tissue from the deleterious effects of fibrosis. Therefore, we sought to investigate the renoprotective effects of darbepoetin alfa on unilateral ureteral obstructions. METHODS: We used 12 female and 12 male 3-monthold Wistar rats weighing between 250 and 350 g. The rats were divided equally into sham, darbepoetin and control groups. With the exception of the sham group, left unilateral obstructions were applied to all of the rats...
