BACKGROUND Ureteroscopy has traditionally been the preferred approach for treatment of distal and midureteral stones, with shock wave lithotripsy used for proximal ureteral stones. OBJECTIVE To describe the differences in the treatment and outcomes of ureteroscopic stones in different locations. DESIGN, SETTING, AND PARTICIPANTS Prospective data were collected by the Clinical Research Offic...

PURPOSE Stone size and location are generally considered the most important factors associated with spontaneous ureter stone passage (SSP). Several parameters related to inflammatory changes have been identified as predictors associated with SSP. Our aim was to investigate the predictive role of neutrophil-to-lymphocyte ratio (NLR) for SSP. MATERIALS AND METHODS A retrospective review was per...

PURPOSE We determined the effect of shock wave lithotripsy (SWL) rate on treatment outcome in patients with renal and ureteral stones. MATERIALS AND METHODS A total of 156 patients were prospectively randomized to receive SWL using a slow (60 pulses per minute) or fast wave rate (120 pulses per minute). Inclusion criteria were patients with a single radiopaque renal or ureteral stone not exce...

OBJECTIVES To compare the safety and cost-effectiveness of ureterorenoscopic holmium:yttrium-aluminum-garnet (YAG) laser lithotripsy (URSL) with extracorporeal shock wave lithotripsy (ESWL) for proximal ureteral stones. METHODS This investigation assessed 220 patients with upper ureteral stones. Those in the ESWL group were treated on an outpatient basis using the Medispec Econolith 2000 (Med...

PURPOSE This study aimed to determine the value of the NTrap® (Cook Urological INC, USA), which was designed to block the upward movement of stones during ureteroscopic lithotripsy. MATERIALS AND METHODS We reviewed the data of 144 patients who underwent ureteroscopic lithotripsy for an upper ureteral stone from June 2006 to May 2010. Sixty-eight patients who underwent ureteroscopic lithotrip...

RATIONALE In patients with bilateral ureteral obstruction, the serum creatinine levels are often elevated, sometimes causing postrenal acute kidney injury (AKI). In contrast, those with unilateral ureteral obstruction present normal serum creatinine levels, as long as their contralateral kidneys are preserved intact. However, the unilateral obstruction of the ureter could affect the renal funct...

AIMS We aimed to obtain the maximum transverse diameters (widths) of ultrasonographically detectable ureteral stones in children and to evaluate the effect of widths on the rate of spontaneous discharge and on the degree of ipsilateral hydronephrosis. MATERIAL AND METHODS We retrospectively evaluated 52 ultrasonographically detected ureteral stones in 51 consecutive patients (32 males, 19 fem...

INTRODUCTION Renal stones are common disorders that affect approximately 5% to 10% of the population and the incidence of renal stones is rising. Treatment of ureteral stones is an important part of urologists and minimally invasive procedures such as ESWL and ureteroscopy effectiveness has been proven in various studies. However, these methods are not completely safe and are expensive and can ...

introduction: the aim of our study was to assess the efficacy and safety of laser lithotripsy in pregnant patients. methods: in this retrospective study, we reviewed the 15 pregnant women who have been treated for ureteral stones with semi-rigid ureteroscope and holmium laser at our center between januarys 2007and april 2015. results: the mean age of patients and mean gestational age was 29.3 y...

BACKGROUND AND PURPOSE The role of early/emergency shockwave lithotripsy (SWL) in symptomatic upper ureteral calculi has still not been established. We have performed a randomized comparison between early (<48 hours) vs delayed (>48 hours) SWL for symptomatic upper ureteral stones less than 1 cm to evaluate the feasibility, safety, and efficacy of early SWL in these patients. PATIENTS AND MET...
