OBJECTIVE: To compare different modalities to aid in the evaluation of intraoperative ureteral patency on cystoscopy in the postindigo carmine era. METHODS: In a randomized controlled trial, participants undergoing pelvic surgery were randomized into one of four groups: saline distention (control), 10% dextrose distention, oral phenazopyridine, or intravenous sodium fluorescein. Our primary outcome was visibility of the ureteral jets. Secondary outcomes included surgeon satisfaction; adverse reactions including allergies, urinary tract infections, urinary retention, cystoscopy times, and ureteral obstruction; and delayed diagnosis...

INTRODUCTION: The risk of kidney stone formation increases with urinary stasis, which is associated with decreased peristaltism. The relationship between nonobstructive kidney stone formation and ureteral jet dynamics, which can be measured with Doppler ultrasonography (US) and provide information about ureteral peristaltism, has been demonstrated in adults. OBJECTIVE: To investigate the relationship between ureteral jet dynamics, which provide information about ureteral peristaltism, and stone formation in children...

REVIEW
Lea Luketic, Ally Murji
Intraoperative cystoscopy has been studied as a means to identify ureteral injuries at the time of gynecologic surgery. The majority of published studies investigating intraoperative cystoscopy have used indigo carmine to dye the urine to allow visualization of ureteral jets; unfortunately, however, this dye is currently not available in North America. The unavailability of indigo carmine may be a permanent reality that forces gynecologists to examine alternatives for the evaluation of ureteral integrity. Various alternative methods have been suggested, ranging from cystoscopy without dye to other commercially available products that dye the urine...

Cystoscopy can be used to diagnose urologic injuries at the time of gynecologic surgery. Current cystoscopy setup involves removing the indwelling catheter placed for the procedure and assembling a multicomponent cystoscope. The objective of this study was to evaluate and report on our initial experience with CystoSure (Emmy Medical, Holliston, MA), a new Food and Drug Administration-approved device designed to facilitate perioperative diagnostic cystoscopy. The CystoSure catheter is an 18F quad-port silicone transurethral catheter with a central sealed port for the cystoscope and a side port that allows for bladder filling...

The incidence of acute kidney injury related to urinary tract obstruction is low (1-10%). It occurs in bilateral renal or lower urinary tract obstruction or in ureter obstruction in patients with a single functioning kidney or with pre-existing chronic kidney disease. The etiology and the incidence of obstruction vary on the basis of age and gender. Conventional ultrasound has a high sensitivity (>95%), but low specificity (<70%) in the diagnosis of urinary tract obstruction. Nevertheless, color Doppler is used through the evaluation of renal resistive indexes, ureteral jet and twinkling artifact...

PURPOSE: Vesicoureteral reflux is the most common urinary tract abnormality in children. Although voiding cystourethrography is the gold standard for diagnosing reflux, this approach is invasive. We evaluated color Doppler ultrasound measurement of ureteral jet angle as a noninvasive screening tool for detecting reflux. MATERIALS AND METHODS: We retrospectively evaluated 125 children (250 renal units) who presented with urinary tract infections or hydronephrosis...

BACKGROUND: Indigotindisulfonate sodium has been used to color the urine and thereby improve the visualization of ureteric jets during intraoperative cystoscopy. After indigotindisulfonate sodium became unavailable, there has been an ongoing search for an alternate agent to improve visualization of the jets. METHOD: We used 50% dextrose, which is more viscous than urine, as the distension medium during cystoscopy so that the ureteric efflux is seen as a jet of contrasting viscosity...

STUDY OBJECTIVE: We sought to identify findings on bedside renal ultrasound that predicted need for hospitalization in patients with suspected nephrolithiasis. METHODS: A convenience sample of patients with suspected nephrolithiasis was prospectively enrolled and underwent bedside ultrasound of the kidneys and bladder to determine the presence and degree of hydronephrosis and ureteral jets. Sonologists were blinded to any other laboratory and imaging data. Patients were followed up at 30 days by phone call and review of medical records...

COMPARATIVE STUDY

In dogs, ultrasonography is performed to locate the ureteral orifices in the urinary bladder, but reference values for their normal location using this technique are missing. In this study, the ureterovesical-vesicourethral and inter-ureterovesical distances were determined in 20 freshly euthanized medium size dogs by detecting artificially produced ureteral jets in color-flow Doppler ultrasonography at two different bladder volumes, and comparing them to manual measurements in the dissected bladder. All distances determined by ultrasonography were in agreement with values found by dissection (P ≥ 0...

UNLABELLED: Renal colic is a common disease in Europe and a common cause of visit to the Emergency Department. Clinical diagnosis is usually confirmed by imaging modalities. Unenhanced computed tomography (CT) is considered the best diagnostic test due to its excellent accuracy detecting ureteral stones. However, ultrasound (US) should be considered as the primary imaging technique. It is a reproducible, non-invasive and non-expensive imaging technique, achieving accurate diagnosis in most cases without the need for radiation...

BACKGROUND: Although renal colic in children in the United States remains relatively uncommon compared to in adults, its incidence has nearly doubled from 1999 to 2008. Noncontrast computed tomography (CT) is the current standard for the evaluation of suspected renal colic, given its high sensitivity and specificity. However, the greater lifetime risk of radiation-induced cancer from CT in pediatric patients has led to efforts to minimize radiation exposure. Additionally, pediatric renal colic is often recurrent, which might require multiple imaging studies during their lifetime...

BACKGROUND: Indigotindisulfonate sodium has been used during cystoscopy to identify the ureteral meatuses and to verify ureteral efflux during pelvic surgery. The U.S. Food and Drug Administration announced the shortage of indigotindisulfonate sodium in June 2014. Surgeons have since been searching for safe alternatives with comparable visualization and an economically favorable profile. METHOD: The recent shortage of indigotindisulfonate sodium prompted our search for alternative options for visualizing ureteral patency during intraoperative cystoscopy...

OBJECTIVE: To evaluate the possible alterations in ureteral jet dynamics which inform physicians about ureteral physiology and peristaltism in nonobstructive kidney stone formers with this prospective-controlled study. MATERIALS AND METHODS: All patients with flank pain eligible for the study underwent Doppler ultrasonoghraphy examination for evaluation of ureteral jet dynamics and non-contrast-enhanced computed tomography for diagnostic reasons. Patients with unilateral nonobstructive lower-pole kidney stone ≤1 cm were defined as group 1 and patients with no evidence of urinary tract stone as group 2...

INTRODUCTION: It still remains an unanswered question whether, in the absence of gynecological malignancy and under elective conditions, to perform abdominal hysterectomy (AH), offering a safer approach, or to perform a laparoscopic hysterectomy (LH) procedure. AIM: We aimed to compare LH operations performed with a tissue fusion device accompanied by intraoperative diagnostic cystoscopy with traditional AH operations involving bilateral ureteral dissection. MATERIAL AND METHODS: The integrity of the ureters, ureteral peristalsis and the diameter of the ureters were examined during AH by inspection...

EDITORIAL
Kjell Tullus
Data reported in this issue of Pediatric Nephrology suggest that the ureteric jet Doppler waveform can predict the occurrence of vesicoureteric reflux (VUR). Many different methods are currently used to detect VUR, including traditional X-ray micturating cystourethrogram, indirect and direct nuclear imaging and contrast enhanced ultrasonography. These methods are invasive, do have some radiation burden and are also quite uncomfortable to paediatric patients. This relatively new non-invasive method is therefore of interest, but its efficacy needs to be confirmed in further studies and, in particular, in babies and infants before it can possibly be considered as a good method to provide clinical information on VUR...

BACKGROUND: Vesicoureteral reflux (VUR) has a prevalence of 30-40 % post-febrile urinary tract infection (UTI). If not detected early and treated, renal scarring, hypertension, and renal failure may occur. Micturating cystourethrography (MCU) is an invasive procedure associated with radiation exposure. Hence, this study aimed at evaluating the utility of ureteric jet Doppler waveform (UJDW) as a screening tool in detecting VUR, and at assessing the feasibility of performing it in children aged 2-4 years...
