OBJECTIVE Urinary lithiasis affects between five and 10% of the human population during their lifetime, only 2-3% of whom are children. Therapy of urolithiasis in the pediatric age group with minimally invasive methodology represents an attractive alternative. This study presents results of extracorporeal shockwave lithotripsy, a minimally invasive methodology, for the treatment of urinary lith...

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 ...

We report a case of retained Double J ureteral stent with huge, multiple calculi at both ends in a 10-year-old female child. The renal and bladder calculi were managed by percutaneous nephrolithotomy and percutaneous cystolitholapaxy in a single sitting.

Spontaneous ureteric rupture (SUR) is an unusual entity associated with perinephric or retroperitoneal extravasation of urine. Patients with SUR are often presented with severe and progressive abdominal or flank pain. It is commonly related to the obstruction of genitourinary system, among which urinary calculi represents the most frequent cause. Prostate cancer with ureteral orifice invasion c...

INTRODUCTION Our aim was to compare transabdominal ultrasonography (US) and intravenous urography (IVU) in the evaluation of patients with hematuria. MATERIALS AND METHODS Two hundred patients with hematuria were assessed by US and IVU, and if needed, by cystoscopy, ureteroscopy, and CT scan, to determine the definite cause of hematuria. The results of US and IVU were compared according to th...

BACKGROUND Stone retropulsion represents a challenge for intracorporeal lithotripsy of ureteral calculi. The consequences are an increased duration and cost of surgery as well as decreased stone-free rates. The use of additional tools to prevent proximal stone migration entails further costs and risks for ureteral injuries. We present the simple technique of using a coil of the routinely used g...

OBJECTIVE To evaluate ureteroscopy as a treatment option for women presenting ureteral calculi during pregnancy. MATERIALS AND METHODS Eighteen pregnant patients presenting renal colic and indication of surgical treatment for ureteral calculi were analyzed. Patients were 20 to 34 years old (medium = 28), and the gestation period ranged from 12 to 34 weeks (medium = 18). Lumbar pain was presen...

Introduction: Our aim was to compare transureteral lithotripsy (TUL) and extracorporeal shock wave lithotripsy (SWL) in the management of upper ureteral calculi larger than 5 mm in diameter. Materials and Methods: Patients who had upper ureteral calculi between 5 mm and 10 mm in diameter were enrolled in this clinical trial. The calculi had not responded to conservative or symptomatic therapy. ...
