A subcutaneous ureteral bypass (SUB) was placed in a 10-year-old Birman cat for management of unilateral ureterolithiasis. Perioperative occlusion of the nephrostomy tube of the SUB device happened secondary to a severe pyonephrosis. Flushing of the system throught the subcutaneous shunting port was made with saline solution after clamping the urinary bladder catheter. Repetitive flushing of the device was performed daily for 3 days to be sure of the remanent patency of the catheter. Repetitive flushing of the SUB device is a successful renal-sparing treatment for pyonephrosis in a cat and may be considered as an effective treatment option for this condition...

INTRODUCTION: Immediate ureteroscopic treatment for patients presenting to the emergency room with symptomatic ureterolithiasis is more commonly being utilized. Recent reports demonstrate good efficacy for emergency ureteroscopy (URS); however, preoperative predictors of treatment success have not been described. In this study, we report our multicenter experience with emergency URS and identify predictors of successful treatment. We also describe the Emergency Ureteral Stone Treatment (EUST) score, which integrates these predictors and stratifies patients into those that are likely and unlikely to have successful treatment...

INTRODUCTION: Urolithiasis is a common medical condition that accounts for a large number of emergency department (ED) visits each year and contributes significantly to annual healthcare costs. Urinalysis is an important screening test for patients presenting with symptoms suspicious for urolithiasis. At present there is a paucity of medical literature examining the characteristics of ureteral stones in patients who have microscopic hematuria on urinalysis versus those who do not. The purpose of this study was to examine mean ureteral stone size and its relationship to the incidence of clinically significant hydronephrosis in patients with and without microscopic hematuria...

OBJECTIVE: Recent studies have clarified the role of alpha-blockers, such as tamsulosin, for patients diagnosed with ureteral stones <10mm not requiring an urgent intervention. Prior studies have reported low rates of use of MET by emergency physicians. We sought to describe patterns of alpha-blocker use and to determine factors associated with utilization in patients diagnosed with ureterolithiasis in the ED. METHODS: We used data from a randomized trial of CT scan vs...

CASE DESCRIPTION A 3-year-old and a 7-year-old spayed female rabbit (Oryctolagus cuniculus) were evaluated because of digestive stasis associated with renal asymmetry. CLINICAL FINDINGS Neoplasia of the right kidney was diagnosed via cytologic analysis in the 3-year-old rabbit. Ureterolithiasis of the left kidney was diagnosed via abdominal ultrasonography in the 7-year-old rabbit. To evaluate whether unilateral nephrectomy was indicated, evaluation of glomerular filtration rate by dynamic CT (CT-GFR) was performed on both rabbits...

REVIEW
M I Kogan, I I Belousov, Akef Maarouf Yassine Akef Maarouf Yassine
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...

Identifying the etiology of acute pelvic pain in girls is often clinically challenging. Particularly in young girls, it is often difficult to determine if acute pelvic symptoms are originating from a gynecologic source or from a genitourinary or gastrointestinal etiology based on the child's clinical examination alone. Therefore, imaging plays a key role in establishing a diagnosis and in directing medical and surgical treatment. Pediatric gynecologic conditions, which can present acutely with pain or mass or both include ovarian torsion, hematometrocolpos, pelvic inflammatory disease, inguinal hernias containing an ovary or the uterus or both, adnexal cysts, pregnancy, vaginal foreign bodies, and ovarian vein thrombosis...

We present the case of a 37-year-old lady who presented with severe colicky left sided flank pain associated with vomiting, chills and rigors. A non-contrast Computed Tomography of the Kidney Ureter and Bladder was performed which showed a 2-3 mm stone in the pelvic part of the left ureter. Following 2 days of conservative treatment she was still complaining of increasingly severe pain. A contrast computed tomography of the abdomen was performed which was suggestive of a perforation of the left collecting system...

OBJECTIVES: Symptomatic ureterolithiasis (renal colic) is a common Emergency Department (ED) complaint. Variation in practice surrounding the diagnosis and management of suspected renal colic could have substantial implications for both quality and cost of care as well as patient radiation burden. Previous literature has suggested that CT scanning has increased with no improvements in outcome, owing at least partially to the spontaneous passage of kidney stones in the majority of patients...

REVIEW
Toru Kameda, Nobuyuki Taniguchi
Point-of-care abdominal ultrasound (US), which is performed by clinicians at bedside, is increasingly being used to evaluate clinical manifestations, to facilitate accurate diagnoses, and to assist procedures in emergency and critical care. Methods for the assessment of acute abdominal pain with point-of-care US must be developed according to accumulated evidence in each abdominal region. To detect hemoperitoneum, the methodology of a focused assessment with sonography for a trauma examination may also be an option in non-trauma patients...
