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...

Introduction: In this research, [Ho]Holmium chitosan complex production is described in details, followed by determination of complex radiochemical purity, stability and biodistribution (after intra-articular injection) in wild-type male rats. Finally a Ho-166 based chitosan kit for ultimate radiosynovectomy as well as radiotherapy applications was developed. Methods: Ho-chitosan complex was pr...

Introduction: Unsolved choledocholithiasis by endoscopic retrograde cholangiopancreatography is a complicated condition to manage. The incorporation of robotic surgery, a choledochoscope, and a holmium laser as therapeutic tools is likely to increase surgery effectiveness. Our purpose is to present the first Latin American case report of the combined use of these tools to extract a large impact...

OBJECTIVES We reviewed the results of percutaneous ureteral incisions for ureteroenteroanastomotic stricture using the holmium laser. METHODS We performed this procedure through a 6.9-F flexible ureteroscope on 3 ureters in 3 patients. Balloon dilation was not necessary prior to insertion of the ureteroscope. The stricture was incised with the holmium laser with a 200-microm fiber through the...

The tendency for the period of the helically ordered moments in holmium to lock into values which are commensurable with the lattice is studied theoretically as a function of temperature and magnetic field. The commensurable effects are derived in the mean-field approximation from numerical calculations of the free energy of various commensurable structures, and the results are compared with th...

INTRODUCTION To study the efficacy of holmium laser urethrotomy with intralesional injection of Santosh PGI tetra-inject (Triamcinolone, Mitomycin C, Hyaluronidase and N-acetyl cysteine) in the treatment of urethral strictures. MATERIAL AND METHODS A total of 50 patients with symptomatic urethral stricture were evaluated by clinical history, physical examination, uroflowmetry and retrograde u...

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 ...

We take another look at two compounds which have been discussed as possible realizations of “spin ice”, namely holmium titanate and dysprosium titanate. As we have earlier observed, holmium titanate does not display icelike behaviour at low temperatures because the long ranged dipolar interactions between spins are strong compared to the nearest neighbour interactions. We show, analytically, th...

PURPOSE To present our clinical outcomes in the management of anuria in adult patients caused by ureteral calculi by using of ureteroscopy and holmium laser. MATERIALS AND METHODS Nineteen patients presented with calcular anuria with ages between 19 and 48 years. The presentation was anuria with serum creatinine levels of 2-5.5 mg% (mean 3.5) and hyperkalemia in nine patients (5.2-6.1 mmol/L)...

PURPOSE The increasing incidence of small renal tumors in an aging population with comorbidities has stimulated the development of minimally invasive treatments. This study aimed to assess the efficacy and demonstrate feasibility of multimodality imaging of intratumoral administration of holmium-166 microspheres ((166)HoAcAcMS). This new technique locally ablates renal tumors through high-energ...
