BACKGROUND Laser lithotripsy has been used as an alternative to surgical removal of uroliths. OBJECTIVE To describe the procedure and efficacy of laser lithotripsy for removal of lower urinary tract uroliths in horses. Additionally, the ultrastructure and the differences in mineralogy and microstructure from 1 successful and 1 unsuccessful laser lithotripsy case are described. ANIMALS Six c...

introduction: surgical management of pediatric urinary calculi evolved dramatically over the past two decades. however, with the miniaturization of equipment and with improvisation of endourologic techniques, access to the entire pediatric urinary system is possible. ho: yag laser provides more maneuverability during transuretereal lithotripsy (tul) than the pneumatic system which uses a metal ...

OBJECTIVES To review the current literature on intracorporeal laser lithotripsy. METHODS We searched PubMed for relevant reports up to January 2012, using the keywords 'laser', 'lithotripsy' and 'intracorporeal'. RESULTS We studied 125 relevant reports of studies with various levels of evidence. Efficient lithotripsy depends on the laser variables (wavelength, pulse duration and pulse energ...

Results: Their ages ranged from 18 months to 14 years (mean: 8.5 ± 3.5 years). The overall success rate for the holmium:YAG laser lithotripsy (100%) was higher than that of pneumatic lithotripsy (81.8%), but the difference was insignificant (P = 0.087). The complication rate was higher in pneumatic lithotripsy than in holmium:YAG laser lithotripsy (36.4% versus 4%, P = 0.023). Treatment time an...

Background/study aims Laser lithotripsy can effectively fragment complicated biliary stones, but current cholangioscopes are limited by fragility, restricted mobility or moderate visual resolution. The efficacy and safety of a new digital single-operator peroral cholangioscope to guide laser lithotripsy were evaluated. Patients and methods In this prospective single-center series, consecutive p...

PURPOSE To evaluate the effects of a reverse thermosensitive polymer during ureteroscopy with laser lithotripsy in an in vivo porcine model. MATERIALS AND METHODS Six pigs underwent general anesthesia followed by bilateral ureteroscopy with laser lithotripsy of stone phantoms while measuring intrapelvic renal pressures through bilateral nephrostomy tubes. The procedures were performed in one ...

BACKGROUND Hepatolithiasis is very common in East Asia. It is benign in nature, but has a high recurrence rate. It is likely to lead to biliary cirrhosis and increase the risk of cholangiocarcinoma. Hence, the treatment of hepatolithiasis is difficult but vital. In this report, we present a novel approach to manage hepatolithiasis using the choledochoscopic Frequency-Doubled Double pulse Nd:YAG...

OBJECTIVES We conducted a retrospective study to evaluate the efficacy and outcome of shock wave lithotripsy versus semirigid ureteroscopy in the management of the proximal ureteral stones of diameter exceeding 15 mm. METHODS During the 2009-2014 study period, 147 patients presenting with the proximal ureteral stones exceeding 15 mm in diameter were treated. Both shock wave lithotripsy and ur...

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...
