results in group 1, the mean largest and cumulative stone diameters, respectively, were 18.7 ± 5.7 mm and 45.0 ± 12.0 mm. in group 2, the mean volume was 6,288.4 ± 2,733.0 mm3. the overall sf was 96.4% (100% for group 1 and 75% for group 2). the mean number of sessions of eswl and urs, respectively, was 1.4 ± 0.7 and 0.8 ± 0.9 in group 1 and 4.0 ± 2.0 and 1.5 ± 1.3 in group 2. the mean times to...

primary ureteral neoplasms are very rare and its prevalence is less than 1% of all genitourinary neoplasms. we report a symptomatic giant ureteral fibro epithelial polyp in adult women presenting as a bladder mass which was resected ureteroscopically and reported at the first time from iran. cystoscopy is growing use in the treatment of urinary tract lesions cystoscopy can be used in large lesi...

In this study we sought to determine if among individuals with urolithiasis, extracorporeal shock wave lithotripsy (SWL) and ureteroscopy are associated with a higher risk of incident arterial hypertension (HTN) and/or chronic kidney disease (CKD). This was measured in a population-based retrospective study of 11,570 participants with incident urolithiasis and 127,464 without urolithiasis in Th...

Introduction. Urinary stone is a common cause of urinary tract disease. Stone excretion using ureteroscope is effective in inferior ureter. The aim of this study was to investigate the effects of aminophylline on ureteral spasm during ureteroscopy in acute phase of renal colic. Methods. In this double-blind randomized clinical trial, 120 patients with ureteral stones were enrolled and randomize...

Objective. To evaluate and compare the efficacy and safety of retrograde versus antegrade ureteroscopic lithotripsy for the treatment of large proximal ureteral stones. Patients and Methods. We retrospectively analyzed the medical records of patients with proximal ureteral stones >15 mm, treated in our institution from January 2011 to January 2016. Intraoperative parameters, postoperative outco...

BACKGROUND To investigate feasibility and safety of treating simple parapelvic renal cysts using flexible ureteroscopy with the Holmium laser. METHODS Between February 2010 and July 2013, a total of 21 patients, aging from 29 to 71 (49.00 ± 13.23), were diagnosed with parapelvic renal cysts by ultrasonography in combination with contrast-enhanced computer tomography (CT) and intravenous urogr...

In recent years, urology has seen a real explosion in the development of new technologies. Modern treatment techniques replaced classic therapeutic methods, among which open surgery had an important role. Endourologic therapies led to effective and safe interventions, increased patient comfort and reduced costs. The "Saint John" Emergency Clinical Hospital Department of Urology always intended ...

BACKGROUND To examine the contemporary role of ureteroscopy in the diagnosis of upper urinary tract urothelial carcinoma. METHODS We retrospectively evaluated 116 diagnostic ureteroscopies, performed in our institution to rule out primary UTUC. Demographics, cytological findings and interpretation of preoperative imaging were obtained. Ureteroscopic diagnosis and histological results were rec...

We are presenting an interesting case of impacted stone and stent in a pregnant patient. We have proved safe use of ureteroscopy and laser in pregnancy with minimal x-ray exposure.
