INTRODUCTION The aim of this study is to compare the changes in the incision line of prostatic adenoma using a monopolar cutting electrode and holmium laser, as well as the assessment of associated tissue mass and volume loss of benign prostatic hyperplasia (BPH). MATERIAL AND METHODS The material used in this study consisted of 74 preparations of prostatic adenoma obtained via open retropubi...

INTRODUCTION Extracorporeal shockwave lithotripsy (ESWL) is the treatment modality of choice of many urologists for proximal ureteric calculi. In this study, we compared the efficacy and safety of ESWL versus ureteroscopy with holmium laser lithotripsy for the treatment of this group of stones. MATERIALS AND METHODS Between May 1999 and October 2000, 50 patients had ESWL and another 51 patien...

BACKGROUND AND OBJECTIVES The holmium laser has a short absorption depth in tissue and possesses excellent properties both in ablation and hemostasis. We have performed endoscopic incision for ureteral stricture using the holmium laser through a small-caliber ureteroscope. METHODS This method was used on five patients and seven ureters. The etiology of the stricture was stone scar in two pati...

PURPOSE Our objective was to evaluate the use of a holmium laser for transurethral deroofing of a prostatic abscess in patients with severe and multiloculated prostatic abscesses. MATERIALS AND METHODS From January 2011 to April 2014, eight patients who were diagnosed with prostatic abscesses and who underwent transurethral holmium laser deroofing at Pusan National University Hospital were re...

Background: Among various intracorporeal lithotripters, pneumatic lithotripter has become the widely used tool for the treatment of urinary stones. Recently the holmium: YAG laser has been used with a wide range of potential urological applications, including intracorporeal lithotripsy of urinary calculi. Purpose: Compare the effectiveness and complications of treatment for ureteric stones betw...

BENIGN PROSTATIC HYPERPLASIA (BPH) affects 70% of men over age 70 and is a significant cause of morbid. ity in this population.1 Endoscopic surgery for BPH has evolved over the past decade with technological advances that offer significant advantages in perioperative and postoperative morbidity and hospital stay. One of the technological advances has been the holmium laser, a multifunction tool...

We demonstrate the first gain-switched, singly doped, single-mode holmium-doped silicate glass fibre laser that operates at 2.106 microm. Using a gain-switched 1.909-microm thulium-doped fibre laser as the pump source, output pulses of energy 3.2 microJ and pulse duration of 150 ns were generated at 80 kHz and slope efficiency of 44%. Pulse stacking within the holmium-doped fibre laser resulted...

introduction: the aim of this study is to compare holmium laser (ll) with pneumatic lithoclast (pl) in patients with upper ureteral stones and their ability to destruct the stones and making the patient stone free. we also compare the duration of these procedures and their complications, such as urosepsis, perforation, and pushing the stone backward. methods: this has been a clinical randomized...

Objective. Treatment options for urolithiasis in children include URSL and RIRS. Various types of energy are used in the disintegration of deposits in these procedures. We decided to evaluate the usefulness of URSL and RIRS techniques and compare the effectiveness of pneumatic lithotripters and holmium lasers in the child population based on our experience. Materials and Methods. One hundred ei...
