Plasmacytoid urothelial carcinoma is a rare and aggressive form of urothelial carcinoma characterized with delayed presentation and poor prognosis. Very few cases of this carcinoma have been reported in the literature. Here, we report and discuss two cases of bladder plasmacytoid urothelial carcinoma of a 57-year-old male presentedwith renal colic, and a 33-year-old female presented with macroscopic hematuria. Pathologic examinations of thetransurethral biopsies revealed urothelial carcinoma with plasmacytoid appearance...

Primary hyperparathyroidism is one of the most common endocrine diseases, however, it is rare in children. In most cases, it is caused by adenoma of these organs. Its most common complications include urolithiasis, nephrocalcinosis and osteoporosis. CASE REPORT: A 16-year-old patient was admitted to our Clinic because of his first-ever renal colic. The ultrasound examination revealed rightsided hydronephrosis caused by the presence of 9 mm stone in the upper part of the right ureter. In addition, the presence of 8 mm stone in the middle calyx of the left kidney was found...

Steven A Kaplan, Bilal I Chughtai
INTRODUCTION: Although tamsulosin is indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia (BPH), it has also been assessed in clinical studies for other conditions/symptoms and in other populations such as women and children. In this systematic review of randomized studies, the overall safety of tamsulosin was assessed, focusing on these understudied populations. METHODS: Literature searches were conducted using Embase, Medline, and PubMed (inception-December 2015)...

Hereditary xanthinuria (type I) is caused by an inherited deficiency of the xanthine oxidorectase (XDH/XO), and is characterized by very low concentration of uric acid in blood and urine and high concentration of urinary xanthine, leading to urolithiasis. Type II results from a combined deficiency of XDH/XO and aldehyde oxidase. Patients present with hematuria, renal colic, urolithiasis or even acute renal failure. Clinical symptoms are the same for both types. In a third type, clinically distinct, sulfite oxidase activity is missing as well as XDH/XO and aldehyde oxidase...

Appropriate deliberate clinical inertia refers to the art of doing nothing as a positive clinical response. It includes shared decision-making to improve patient care with the use of clinical judgement. We discuss common clinical scenarios where the use of deliberate clinical inertia can occur. The insertion of peripheral intravenous cannulae, investigating patients with suspected renal colic and the investigation of low risk chest pain are all opportunities for the thoughtful clinician to 'stand there' and use effective patient communication to avoid low value tests and procedures...

BACKGROUND: Renal colic is a frequently encountered diagnosis among emergency department patients. Point-of-care (POC) ultrasound has taken on an increasingly important role in the diagnostic strategy of this disease, as it has been shown to be an effective modality for diagnosis and for guiding management. The primary pathology that the emergency physician will evaluate for in cases of suspected renal colic is hydronephrosis, which is a dilatation of the renal pelvis and calyces resulting from a distal obstruction such as a ureteral stone...

PURPOSE: In the emergency setting, flank pain commonly leads to a noncontrast CT despite a significant percentage of patients having alternative diagnoses, often difficult to characterize without contrast. We investigated the combined utility of urinalysis and history of urolithiasis in identifying patients who are unlikely to have urolithiasis and may benefit from a contrast-enhanced study. METHODS: Retrospective review of 350 patients from May 2013 to May 2016 was performed for patients in the emergency department with renal colic that underwent noncontrast CT and urinalysis testing...

INTRODUCTION: Menstrual cup is increasingly gaining acceptance among women to control the menstrual period. The majority of brands advocate that these devices are 100% safe to the users, notwithstanding there are some reports of rare complications associated with these devices. PRESENTATION OF CASE: In this case we present a woman who developed a right renal colic using a menstrual cup. The pain was difficult to manage with conventional analgesics. The plain abdominal X-ray revealed the device in the pelvis occupying more than one third of the pelvis minor diameter and oriented to the right side...

OBJECTIVE: The ability of emergency physicians (EP) to identify hydronephrosis using point-of-care ultrasound (POCUS) has been assessed in the past using CT scans as the reference standard. We aimed to determine the ability of EP for identifying and grading of hydronephrosis on POCUS using the consensus interpretation of POCUS by emergency radiologists as the reference standard. METHODS: The study was conducted at an urban academic emergency department (ED) as a secondary analysis of previously collected ultrasound data from the EP performed POCUS-databank...

Background: The ureteral stent provides a conduit for urinary drainage from the kidney to the bladder and is integral to contemporary urologic practice. A ureteral stent is often utilized in acute conditions to prevent or overcome obstruction; however, in nonsurgical patients, because of disease or preference, a ureteral stent may be used as a last resort for long-term management of a stricture in lieu of a nephrostomy tube. This case highlights a patient whose chronic ureteral obstruction has been managed with an indwelling ureteral stent for 25 years; remarkably, stent exchanges are currently required only every 2 years...

BACKGROUND: Non-contrast computed tomography of the kidneys, ureters, and bladder (CT KUB) is the investigation of choice for renal colic; however, radiation exposure can be a concern. AIMS: The study aimed to investigate the diagnostic accuracy of low dose (LD) and ultra-low dose (ULD) CT of the urinary tract for detection of urinary tract stones in patients with renal colic. METHODS: A Cochrane style systematic review of the literature from 1995 to 2017 was carried out...

BACKGROUND: Assessment of pelvic configuration is an important factor in the prediction of a successful vaginal birth. However, manual evaluation of the pelvis is practically a vanishing art, and imaging techniques are not available as a real time bed side tool. Unlike the obstetrical conjugate diameter (OC) and inter spinous diameter (ISD), the pubic arch angle (PAA) can be easily measured by transperineal ultrasound. OBJECTIVES: Three dimensional computed tomography bone reconstructions were used to measure the three main birth canal diameters, evaluate the correlation between them and establish the normal reference range for the inlet, mid- and pelvic outlet...

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...

PURPOSE: To study the clinical application of low-dose unenhanced computed tomography with iterative reconstruction technique (LDCT-IR) on renal colic in the emergency department. MATERIALS AND METHODS: We conducted a prospective, single-blinded, randomized, and non-inferiority study. From March 2014 to August 2015, 112 patients with renal colic were included, and were randomized to either LDCT-IR (n=46) or standard-dose unenhanced CT (SDCT) (n=66) groups. The accuracy of urolithiasis diagnosis was the primary endpoint of this study...

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...
