A nanoparticle (NP) doping technique was developed for fabricating erbium (Er)- and holmium (Ho)-doped silica-based optical fibers for high energy lasers. Slope efficiencies in excess of 74% were realized for Er NP doping in a single mode fiber based master oscillator power amplifier (MOPA) and 53% with multi-Watt-level output in a resonantly cladding-pumped power oscillator laser configuration...

OBJECTIVE To analyse outcomes of holmium laser and pneumatic lithotripsy in treatment of lower ureteric calculus in pediatric patients. MATERIALS AND METHODS Prospective study conducted between August 2013 and July 2015. Inclusion criteria were lower ureteric calculus with stone size ≤1.5cms. Exclusion criteria were other than lower ureteric calculus, stone size ≥1.5cms, congenital renal anom...

Fiber-optic attraction of urinary stones during laser lithotripsy may be exploited to manipulate stone fragments inside the urinary tract without mechanical grasping tools, saving the urologist time and space in the ureteroscope working channel. We compare thulium fiber laser (TFL) high pulse rate/low pulse energy operation to conventional holmium:YAG low pulse rate/high pulse energy operation ...

OBJECTIVE To show the efficiency and safety of Holmium laser in the treatment of pyeloureteral lithiasis, based on our own experience since the introduction of this source of energy in our department. MATERIAL AND METHODS From January 2002 to February 2004, we have carried out 198 ureterorenoscopies using Holmium laser to treat lithiasis located in the upper urinary tract. In all cases, a pre...

Introduction: Our aim was to compare two types of lithotripter including holmium: YAG laser and pneumatic one in transurethral ureterolithotripsy (TUL) for the management of ureteral calculi ≥1 cm. Methods: 112 patients with ureteral calculi more than 1 cm were selected in randomized order for pneumatic or holmium: YAG laser transurethral ureterolithotripsy (56 patients in each group). Ultrason...

BACKGROUND AND OBJECTIVES Advances in endoscopic techniques have transformed the management of urolithiasis. We sought to evaluate the role of such urological interventions for the treatment of complex biliary calculi. METHODS We conducted a retrospective review of all patients (n=9) undergoing percutaneous holmium laser lithotripsy for complicated biliary calculi over a 4-year period (12/200...

PURPOSE To evaluate the clinical efficacy of flexible ureteroscope (F-URS) combined with holmium laser lithotripter in treating renal calculi in horseshoe kidney. MATERIALS AND METHODS From November 2010 to December 2013, the medical history and charts of sixteen patients (mean age 42.9 ± 11.6 years, range 26-66 years), including 13 males and 3 females were analyzed retrospectively. Mean ston...

BACKGROUND In 1996, Holmium laser enucleation of the prostate was introduced and has been shown to be safe and highly effective. CASE PRESENTATION We report a case of a rare complication that resulted in intra-abdominal compartment syndrome with prolonged intubation and intensive care, involving an 74-year-old male after holmium laser enucleation of prostate, with a massive irrigant fluid lea...

Endoscopic management of ureteral calculi is one of the most important therapies in academic centers. Amongst these Laser and Pneumatic Lithotriptors are gaining popularity. This study was designed to study the efficacy and outcomes of both the available Lithotriptors. 200 patients presenting to the Urology OPD in our tertiary center were divided into 2 groups; first group being treated with pn...

endourologic pyeloplasty is being a substitute of open pyeloplasty in management of ureteropelvic junction obstruction. this procedure can be done in different manners like balloon dilation, cold knife and electrosurgical endoureterotomy, accucise and lasers.a 47 year old woman referred with history of previous open pyeloplasty. hydronephrosis of right kidney with unremarkable t ½ was found in ...
