Introduction: The aim of this study was to compare the results and complications of extracorporeal shock wave lithotripsy (SWL) plus retrograde ureteroscopic lithotripsy using laser and pneumatic lithotriptors with SWL monotherapy for renal pelvic calculi between 2 cm and 3 cm. Materials and Methods: A total of 55 patients with 2to 3-cm pelvic calculi were assigned into groups 1 and 2, includin...

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...

OBJECTIVE To compare the stone clearance of upper with middle and lower ureteric stones by using ureteroscopic pneumatic lithotripsy. METHODS The study was conducted in the Department of Urology, Liaquat National Hospital, Karachi, from February 2009 to February 2010. A total of 90 patients were selected and divided into three groups of 30, each according to the location of stone in the urete...

BACKGROUND Patients with end-stage liver disease have an increased risk of symptomatic gallstone disease, as well as complications associated with cholecystectomy. We hypothesized that peroral transpapillary cholecystoscopy with electrohydraulic lithotripsy of gallbladder stones is technically feasible and beneficial in patients who are high operative risks. DESIGN Observational, descriptive....

OBJECTIVE We aimed to compare the effectiveness of holmium YAG laser and pneumatic lithotripsy in the treatment of ureteral stones. MATERIAL AND METHODS A total of 216 patients who had established indications of ureteroscopy between November 2011 and June 2012 were included in this study. Patients' files were retrospectively reviewed by dividing cases as groups that underwent pneumatic (PL) o...

PURPOSE OF REVIEW Shock-wave lithotripsy has been the mainstay of urinary-stone treatment over the past 20 years, with three generations of lithotripters now in the market place. Little improvement, however, has been made in the overall efficiency, since the original Dornier HM3 lithotripter. Over the past 5 years much progress has been made in the basic research of shock-wave lithotripsy, with...

from sep. 1984 to aug. 1990,99 patients were treated for ureteral stone using the urekroscope. in five patients ureteroscopy was repeated for a second stone. in one patient the procedure was diagnostic in nature and in the rest of the patients it had a curative value. in 60 patients the stone was removed by electrohydraulic and basket combination and in25 cases, dilatation alone was enough. rat...

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...

the incidence of stone disease among patients with congenital renal anomalies including malrotated kidney is more than in normal population due to poor urine drainage and stasis (1). various minimally invasive options have been used for the management. ureteroscopy and holmium:yag laser lithotripsy have been reported with favorable outcomes (2). we report a 30-year-old male who presented to our...
