OBJECTIVE The aim of the study was to determine if the degree of hydronephrosis on focused emergency renal ultrasound correlates with kidney stone size on computed tomography. METHODS A retrospective study was performed on all adult patients in the emergency department who had a focused emergency renal ultrasound and ureterolithiasis on noncontrast computed tomography. Severity of hydronephro...

Introduction: Hysterectomies are the second most common major surgical procedure among women in their reproductive years. Ureteral injury is a known complication of this surgery. Intraoperative cystoscopy is not yet used routinely to evaluate the ureteral function before concluding a benign hysterectomy. Case Description: A 40-year-old woman had a laparoscopy-assisted vaginal hysterectomy with ...

INTRODUCTION Stone retropulsion during ureteroscopic lithotripsy may lead to additional procedures needed for residual calculi. Several devices have been introduced in an attempt to reduce retropulsion. We set out to report our initial experience utilizing the new polymeric gel, BackStop. MATERIAL AND METHODS We prospectively collected data on 7 ureteroscopy procedures with distal ureteral ca...

In order to promote stone passage in renal colic, we must first understand normal ureteral activity and how this is affected by the presence of a stone. Measuring normal ureteral activity in humans is difficult without the use of invasive methods or techniques which in themselves may affect peristalsis. Monitoring the activity during confirmed renal colic is even more difficult and virtually im...

OBJECTIVES Non-contrast computed tomography (NCCT) is not always performed clinically if the diagnosis of ureteral calculi has been confirmed using other radiographic imaging modalities. The aim of this study was to identify predictors of successful extracorporeal shockwave lithotripsy (ESWL) without assistance of NCCT. METHODS We retrospectively reviewed the medical records of patients with ...

Urolithiasis is a well-known and common late complication in patients with urinary diversion. Patients without urinary diversion lead to symptoms such as hematuria and ureteral colic, whereas stones in patients with urinary diversion tend to be asymptomatic and are often diagnosed incidentally during staging examinations of oncologic diseases. We report the case of a 64-year-old male patient wi...

Purpose. We aimed to compare and evaluate the outcomes and complications of two endoscopic treatment procedures, semirigid ureteroscopy (SR-URS) and flexible ureteroscopy (F-URS), in the treatment of proximal ureteral stones (PUS). Methods. SR-URS (group 1) was done on 68 patients whereas 64 patients underwent F-URS (group 2) for the treatment of PUS. Success rate was defined as the absence of ...

Background: Protease inhibitors (PIs) are a well-documented cause of nephrolithiasis. Although medications such as indinavir are known to increase risk of stone formation, the association of newer HIV medications is not as well studied. In this study, we report a case of a patient who developed atazanavir stones. Case Presentation: A 74-year-old man with HIV on antiretroviral therapy-including ...
