Purpose This study aims to assess the predictive factors and treatment outcomes of Steinstrasse formation following shock wave lithotripsy (SWL) for ureter stone. Materials and Methods The medical records of 1,418 ureter stone patients who underwent one-session SWL from November 2005 to May 2013 at our medical institute were retrospectively reviewed. Finally, 551 patients met inclusion criter...

OBJECTIVES In this study, we aimed to analyze the ureter stones that had been treated using rigid ureteroscopy and pneumatic lithotripsy without mechanically dilating the ureteral orifice. PATIENTS AND METHODS Records of 110 patients who had undergone rigid ureteroscopy and pneumatic lithotripsy due to ureteral stone between February 2005 and May 2011 were retrospectively analyzed. The locati...

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...

Results: Stone size greater than 0.67 centimeters and location in the proximal ureter were found to be statistically significant in predicting complications. When individualizing operative complications with stone characteristics, a stone density of 817 Hounsfield units (HU) or greater, stone size of 0.79 centimeters or greater, and operative time greater than 53 minutes all showed statistical ...

Ureteral duplication is a common congenital anomaly of the urinary system observed in 0.8% of autopsy series [1]. However, bifid ureter with a blind branch is a rare condition. It is three times more prevalent in women than men and is observed twice as often on the right side as on the left side [2]. It does not generally give any clinical symptoms. However, in the literature, symptomatic cases...

OBJECTIVES A prospective, multicenter, randomized, double-blind, placebo-controlled trial evaluated the effects of naftopidil 75 mg for medical expulsive therapy for a single ureter stone. MATERIALS AND METHODS Patients diagnosed with a ureter stone were prescribed aceclofenac 100 mg or a combined medication of tramadol 37.5 mg and acetaminophen 325 mg. Patients then randomly received either ...

PURPOSE The aim of this study was to evaluate the outcome of ureter stones with expectant management and the clinical factors associated with stone passage in Koreans. MATERIALS AND METHODS We reviewed the charts of patients who visited the emergency room or urological office of our institution with acute renal colic between 2001 and 2008. A total of 656 ureter stone formers were enrolled in ...

A 28-year old man presented with left flank pain and dysuria. Plain abdominal film and computed tomography showed a left giant ureteral stone measuring 11.5 cm causing ureteral obstruction and other stones 2.5 cm in size in the lower pole of ipsilateral kidney and 7 mm in size in distal part of right ureter. A left ureterolithotomy was performed and then a double J stent was inserted into the u...

This study aimed to evaluate the clinical value of a novel ureter dilatation method during ureteroscopic pneumatic lithotripsy in patients with ureteral calculi and polyps. Clinical information of 86 patients with ureter calculi and polyps who underwent ureteroscopic pneumatic lithotripsy was reviewed. A cavity-distention machine was used in 44 cases to inject normal saline for keeping clear op...
