Ureterolithiasis

BACKGROUND: We aimed to investigate the factors predicting the need for ureteral J stent placement in the treatment of distal ureteral stones by ureteroscopy (URS). METHODS: Between January 2007 and June 2018, 550 consecutive patients who underwent URS with the diagnosis of distal ureteral stone disease were evaluated in a single center. The patients were divided into two groups as; group 1 who received a ureteral J stent, and group 2 without ureteral J stent. The two groups were compared in terms of possible preoperative, perioperative and postoperative risk factors...

Dilatation of foetal urinary collecting system is common. But cause of obstruction, if any, arise from soft tissues or developmental abnormalities of urinary tract or other paradox. A prenatal diagnosis of a 'calculus' inside ureter producing obstruction and ultimate back pressure changes in collecting system of a foetus is not reported so far. Other than inborn error of metabolism, what aetiological factors lead to this, are a matter of concern and great research. Here kidneys are not dysplastic. Amniotic fluid volume remains normal...

OBJECTIVES: Clinicians have minimal guidance regarding the clinical consequences of each radiologic imaging option for suspected renal colic in the emergency department (ED), particularly in relation to patient-centered outcomes. In this scoping review, we sought to identify studies addressing the impact of imaging options on patient-centered aspects of ED renal colic care to help clinicians engage in informed shared decision making. Specifically, we sought to answer questions regarding the effect of obtaining computed tomography (CT; compared with an ultrasound or delayed imaging) on safety outcomes, accuracy, prognosis, and cost (financial and length of stay [LOS])...

OBJECTIVES: The aim of this study was to determine whether preoperative ultrasound imaging characteristic(s) in cats suffering from unilateral benign ureteral obstructions are predictive of outcome after successful renal decompression with a subcutaneous ureteral bypass (SUB) device. METHODS: This was a retrospective study of 37 cats with unilateral, benign ureteral obstruction. Preoperative imaging characteristics (including renal pelvis diameter, parenchymal thickness [transverse plane], renal length and pelvic size:overall renal size) and biochemical data were evaluated for all cats diagnosed with a unilateral ureteral obstruction treated with a SUB device...

INTRODUCTION: The aim of this article was to compare retrograde intrarenal surgery (RIRS), antegrade ureterorenoscopy (URS), and laparoscopic ureterolithotomy (LU) for impacted proximal ureter stones larger than 1.5 cm in terms of operative data, success, complications, auxiliary treatment rates, and visual analog scale (VAS) scores. MATERIAL AND METHODS: Medical records of patients undergoing RIRS, antegrade URS, or LU were retrospectively reviewed. After exclusion criteria, 122 patients were included in advanced analyses...

In this review article, we will discuss the gamut of abnormalities involving the ureters. In the emergency department, ureterolithiasis is the most common indication for imaging abdomen and pelvis. However, spectrum of ureteral abnormalities including congenital, infectious and inflammatory, primary and secondary ureteral malignancies, retroperitoneal fibrosis rare described in this article may be encountered. Thus, we will describe acute subacute as well as chronic conditions that may affect ureter. Knowledge of common, as well as rare entities and their imaging features, is of utmost importance to enable appropriate management...

X-ray-free endoscopic combined intra renal surgery (ECIRS) is a feasible alternative to avoid radiation exposure to both surgical teams and patients, but has not been reported prior. The aim of this report is to present our first-hand experience of performing X-ray-free ECIRS for complex ureteral stone. A 57-year-old female presented with right flank pain, fever, dysuria, and leukocytosis. The computed tomography scan showed right impacted proximal ureteral stone sized 33 ´17 mm and grade IV hydronephrosis...

BACKGROUND: Approximately 2 million patients present to emergency departments in the USA annually with signs and symptoms of ureterolithiasis (or renal colic, the pain from an obstructing kidney stone). Both ultrasound and CT scan can be used for diagnosis, but the vast majority of patients receive a CT scan. Diagnostic pathways utilizing ultrasound have been shown to decrease radiation exposure to patients but are potentially less accurate. Because of these and other trade-offs, this decision has been proposed as appropriate for Shared Decision-Making (SDM), where clinicians and patients discuss clinical options and their consequences and arrive at a decision together...

A 13-year-old patient presented to the emergency department with a history of abdominal pain and right flank pain. Two days before, she was evaluated at her pediatrician's office and was diagnosed with acute gastroenteritis and sent home. In the emergency department, the patient was diagnosed with ureterolithiasis after a physical examination, laboratory work, and imaging findings. She was treated successfully with conservative medical management. Symptomatic presentation of ureterolithiasis can include abdominal pain, flank pain, hematuria, dysuria, urgency, nausea, and vomiting...

BACKGROUND: Adrenal incidentaloma (AI) has been frequently encountered in the clinical setting. It has been shown that primary aldosteronism (PA) or subclinical Cushing's syndrome (SCS) are the representative causative diseases of AI. However, the coexistence of PA and SCS has been reportedly observed. Recently, we encountered a case of AI, in which PA and SCS coexisted, confirmed by histopathological examinations after a laparoscopic adrenalectomy. We believe that there were some clinical implications in the diagnosis of the present case...

INTRODUCTION Distal ureteral stones (DUS) are common in patients presenting to the emergency department (ED) with renal colic. The majority of DUS will pass spontaneously and therefore conservative care is common. Follow up is imperative as some of these stones might not pass and potentially lead to complications. The aim of our study was to evaluate the rate of compliance with follow up and to find predictive variables for it. MATERIALS AND METHODS: We retrospectively surveyed the medical records of all patients who had a non-contrast computed tomography (NCCT) at our ED between 01/03/16 and 31/5/17...

The ureteral avulsion is the most horrific complication of ureteroscopy. The traditional treatment of ureteral avulsion is open ureteral repair. However, mucosal avulsion is a new terminology that could be managed endoscopically. Herein, we present a patient with mucosal avulsion. This case was followed-up with imaging and there wasn't any evidence of ureteral stenosis. We believe that mucosal ureteral avulsion could be managed by endourology techniques in selected patients. However, pros and cons of this treatment option should be carefully discussed with patients and long term follow up is necessary in these group of patients...

Bilateral intravesical ureteroceles is a rare condition where both ureters terminally end in cystic dilations in the urinary bladder. Herein, a 31-year-old male patient presented with severe right flank pain and gross hematuria. Upon computed tomography imaging, a right ureterocele with an entrapped stone was revealed. Direct visualization also showed a smaller ureterocele at the left ureterovesical junction. Both ureteroceles were unroofed using rigid resectoscope with cold knife resulting in rapid bilateral efflux...

BACKGROUND: Governments have implemented social distancing interventions to curb the speed of SARS-CoV-2 spread and avoid hospital overload. SARS-CoV-2 social distancing interventions have modified several aspects of society, leading to a change in the emergency medical visit profile. OBJECTIVE: To analyze the impact of COVID-19 and the resulting changes on the non-SARS-CoV-2 emergency medical care system profile. METHODS: This is a retrospective multicenter cross-sectional study evaluating medical consultations, urgent hospitalizations, and deaths in São Paulo, the largest city of the Americas...

Purpose: To address whether preoperative tamsulosin increases the rate of successful ureteral orifice navigation for ureteroscopy (URS) without prestenting in school-age pediatric patients. Methods: We retrospectively reviewed all pediatric patients who had undergone ureteroscopy (URS) at our institution from 2013 to 2020. Patients were divided into two groups: those who had received tamsulosin 0.4 mg daily ≥48 hours preoperatively and those who had not. Statistical analysis was done using independent-sample t -tests and Mann-Whitney U tests for continuous variables, and χ2 and Fisher's exact tests were used for categorical variables...

Objective: To determine the external validity of STONE score for predicting the probability of ureteral stone in patients presenting in emergency department with suspicion of ureteral stones. Methods: In this prospective validation study, a total of 134 patients aged above 18 years, and first time arrived in the emergency unit for treatment of flank pain and then referred for the CT scan for suspected ureteral stone in Sandeman Provincial Hospital, Quetta, from 10-June-2018 to 15-Oct-2019 were included...

Introduction: The most common cause of acute renal colic is a ureteral obstruction caused by ureterolithiasis. Urgent intervention is often necessary due to intractable pain. Early extracorporeal shockwave lithotripsy (SWL) as an alternative treatment option to ureteral stenting becomes forgotten in times of rising ureterorenoscopy. However, definitive guidelines are lacking, in which urgent treatment should be preferred in the absence of signs of infection. Therefore, we assessed efficacy and safety of early SWL (eSWL) to secondary SWL (sSWL) after urgent ureteral stenting...

Giant ureteral calculi stones defined as larger than 5 cm in length or circumference. Although many giant ureteral stones have been reported, the laparoscopic removal of these stones is rare. A 45-year-old male patient presented to our clinic with right flank pain and discomfort from 6 months ago. Abdominopelvic computed tomographic scan showed a giant left middle ureteral stone. On the first stage laparoscopic ureter lithotomy was performed with 3 ports and the stone was extracted from 12 mm port successfully...

Ureterolithiasis in the pediatric population is uncommon and may mimic acute abdomen. While the majority of small stones pass spontaneously, complications may ultimately warrant surgical intervention. As the majority of affected patients have a predisposing condition, targeted therapy with close and consistent follow-up may prevent recurrence, emphasizing timely diagnosis. The authors present the case of a previously healthy 13-year-old boy with eight days of right lower quadrant abdominal pain and emesis, who was found to have a distal ureteral stone necessitating surgical intervention...
