OBJECTIVE Low back pain, caused intervertebral disc degeneration has been treated by thermal annuloplasty procedure, which is a non-surgical treatement. The theoretical backgrounds of the annuloplasty are thermal destruct of nociceptor and denaturization of collagen fiber to induce contraction, to shrink annulus and thus enhancing stability. This study is about temperature and its distribution ...

OBJECTIVE To assess the the efficacy and early and late complications of Argon-YAG combined laser iridotomy in the outpatient department of a tertiary care hospital. METHODS This was a prospective observational study conducted at Aga Khan University Hospital Karachi, Pakistan. After detailed history taking and clinical examination, patients who had goniscopically evident closed angles and a p...

BACKGROUND Treatment of congenital melanocytic nevi (CMN) with intense pulsed light (IPL) has recently produced promising results. OBJECTIVE To evaluate the clinical and histological outcomes of small-to-medium sized CMN treated with IPL alone and in combination with erbium: yttrium-aluminum-garnet (Er: YAG) laser. METHODS We performed a retrospective chart review of 26 small-to-medium size...

Introduction: Pearly penile papules are common, benign lesions that may be a source of concern and embarrassment for many men. Therapeutic options such as electrodessication, shave excision, cryotherapy, and CO2 laser ablation have demonstrated variable degrees of efficacy, and may result in scarring and hypopigmentation. Holmium: YAG lasers are widely available to most urologists, and have ope...

BACKGROUND AND PURPOSE To establish a less invasive and reproducible focal ischemia model in the rat, we adopted a 2-laser system (ie, photothrombosis and YAG laser-induced reperfusion). METHODS The distal middle cerebral artery (MCA) of spontaneously hypertensive rats was occluded by 568-nm krypton laser and intravenous infusion of the photosensitizing dye rose bengal and was recanalized by ...

Three kinds of apparatus of CO2 laser, that is, Medilaser S, NIIC Lasery 60 and NIIC Lasery Model 60Z, are used in our institute. Two kinds of apparatus of Nd-YAG laser, that is, Molectron Model 8000 and Medilas are utilized also. We have used CO2 lasers for removal of tumors in 75 brain tumor cases and 9 spinal cord tumor cases. CO2 lasers were also used for hemostasis in the muscle layer and ...

The numerous types of vascular abnormality are classified in groups according to their pathological and anatomical features. We present case histories of 2 patients who had vascular malformations of the face since birth or early childhood. Application methods, side-effects and complications of percutaneous and intra-lesional Nd:YAG-laser therapy are reviewed for these patients. A 54-year-old wo...

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...

PURPOSE TO EVALUATE THE EFFICACY AND SAFETY OF THE HOLMIUM: yttrium-aluminium-garnet (YAG) laser for the treatment of urethral/bladder neck strictures after high-intensity focused ultrasound for prostate cancer. METHODS Between February 2007 and July 2010, Holmium: YAG laser urethrotomies were performed in eleven patients for bladder neck strictures or prostatic urethral strictures. The laser...

PURPOSE We evaluated the effectiveness and safety of holmium: YAG laser lithotripsy with a semirigid ureteroscope for ureteral calculi in a prospective cohort of 697 patients. PATIENTS AND METHODS Holmium: YAG laser lithotripsy was performed with a semirigid ureteroscope in 697 inpatients between September 2002 and January 2006. Calculi were located in the distal ureter in 382 patients (54.8%...
