PURPOSE For treating proximal ureteral calculi, treatment decision has been known still difficult to choose ureteroscopic lithotripsy (URS) or shockwave lithotripsy. The aims of our study are to identify the possible predictors for necessity of URS and to propose the Gachon University Ureteral Narrowing scoring system (GUUN score) as a helpful predictor. MATERIALS AND METHODS We evaluated 83 ...

Spinal cord injury (SCI) may lead to urinary system disturbances. Patients with SCI usually have neurogenic bladder, and treatment optionss for this condition include clean intermittent catheterization and a permanent indwelling urethral or suprapubic catheter. Complications of catheterization include urinary tract infection, calculi, urinary tract injury, bladder contraction, bladder spasm, re...

A 50-year old woman was admitted to emergency room due to an episode of recurrent renal colic. Double-J ureteral stent has been placed several weeks earlier due to mild hydronephrosis of the left kidney. She had a history of urinary tract infections and poorly defined abdominal pain. Abdominal computed tomography (CT) scan revealed normal left kidney and normal left urinary tract without calcul...

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...

PURPOSE It is thought that the 3 narrowest points of the ureter are the ureteropelvic junction, the point where the ureter crosses anterior to the iliac vessels and the ureterovesical junction. Textbooks describe these 3 sites as the most likely places for ureteral stones to lodge. We defined the stone position in the ureter when patients first present to the emergency department with colic. ...

PURPOSE To evaluate hyoscine N-butyl bromide (HBB) and three different alpha-1 blockers in the treatment of distal ureteral stones. MATERIALS AND METHODS A total of 140 patients with stones located in the distal tract of the ureter with stone diameters of 5 to 10mm were enrolled in the present study and were randomized into 4 equal groups. Group 1 received HBB, Group 2 received alfuzosin, Gro...

BACKGROUND This research aims to evaluate the role of tamsulosin in the medical expulsion therapy for distal ureteral stones, including her effects in stone expulsion time, expulsion rates, stone size, pain episodes and analgesic dosage usage. MATERIAL AND METHODS The 104 patients with distal ureteral calculi were examined, with the size of the stones 4-10 mm. They were randomly divided into ...

background a review of the related medical journals indicates that there is no definite evidence-based option for managing large proximal ureteral stones, although many procedures such as transureteral lithotripsy (tul), shock wave lithotripsy (swl), percutaneous nephrolithotripsy, laparoscopic ureterolithotomy, and open ureterolithotomy are currently used to treat this urological problem. obje...

INTRODUCTION Minimally invasive treatment of ureteral calculi in children is a challenging topic. In an evidence-based review, we evaluated the efficacy and safety of extracorporeal shock wave lithotripsy (SWL) and ureteroscopic modalities for this group of patients. MATERIALS AND METHODS In this study, we performed a comprehensive systematic review on articles appeared in the PubMed from 199...
