Treatment of Urolithiasis with Thulium Fiber Laser in Fragmentation Mode Using Optimized Pulse Sequences.

The super-pulsed thulium fiber laser (SP TFL) is a new alternative to high-power holmium laser for intracorporeal lithotripsy. The SP TFL has shown advantages in dusting regimes, but benefits in fragmentation regimes are less understood. The second-generation SP TFL introduces an advanced fragmentation pulse (AFP) sequence to maximize SP TFL's efficiency in fragmentation.

Conventional white light imaging-assisted transurethral resection of bladder tumour (TURBT) versus IMAGE1S-assisted TURBT in non-muscle-invasive bladder cancer patients: trial protocol and 18 months results.

Purpose: White light (WL) is the traditional imaging modality for transurethral resection of bladder tumour (TURBT). IMAGE1S is a likely addition. We compare 18-mo recurrence rates following TURBT using IMAGE1S versus WL guidance.

Clinical Comparison of Super Pulse Thulium Fiber Laser and High-Power Holmium Laser for Ureteral Stone Management.

To evaluate the efficacy of new super pulse thulium fiber laser (SP TFL) and compare it with holmium laser for ureterolithotripsy. A total of 174 patients with solitary ureteral calculi were enrolled in 2016 to 2018. Stone sizes ranged between 0.

Thermoexpandable Urethral Nickel-Titanium Stent Memokath for Managing Urethral Bulbar Stricture After Failed Urethroplasty.

Urethral stenting became popular two decades ago, but nowadays its frequency is slightly decreased because of the rising application of urethroplasty. Today urethral stenting is reserved only for failure after urethral reconstruction or in cases when the plastic surgery is unfavorable. The Memokath stent (Pnn Medical A/S, Kvistgaard, Denmark) is manufactured from a biocompatible alloy of nickel and titanium and known to be the most popular in this field.

Transurethral resection of a large bladder hemangioma of mixed histological composition: a case report.

Hemangioma is a rare benign vascular tumor of the bladder, which occurs mainly in children. It has no specific clinical symptoms but can result in severe and fatal complications as well as relapse. In the current clinical observation, a 35-year-old patient had a large solid tumor of the bladder spreading into the muscular layer.

Risks and Benefits of Postoperative Double-J Stent Placement After Ureteroscopy: Results from the Clinical Research Office of Endourological Society Ureteroscopy Global Study.

Purpose: Double-J stent placement after stone removal by ureteroscopy (URS) is common and recommended in many cases but debatable in others. In this study, the risks and benefits of postoperative Double-J stent placement in URS stone treatment procedures undertaken in current clinical practice are examined.

Materials And Methods: The Clinical Research Office of Endourological Society (CROES) URS is a prospective, observational, international multicenter study, in which patients are candidates for URS as primary treatment or after failure of prior treatment for ureteral and renal stones.

En bloc resection of urothelium carcinoma of the bladder (EBRUC): a European multicenter study to compare safety, efficacy, and outcome of laser and electrical en bloc transurethral resection of bladder tumor.

Purpose: En bloc resection of bladder tumors (ERBT) may improve staging quality and perioperative morbidity and influence tumor recurrence. This study was designed to evaluate the safety, efficacy, and recurrence rates of electrical versus laser en bloc resection of bladder tumors.

Methods: This European multicenter study included 221 patients at six academic hospitals.

Technical solutions to improve the management of non-muscle-invasive transitional cell carcinoma: summary of a European Association of Urology Section for Uro-Technology (ESUT) and Section for Uro-Oncology (ESOU) expert meeting and current and future perspectives.

The aim of the present review was to compare state-of-the-art care and future perspectives for the detection and treatment of non-muscle-invasive transitional cell carcinoma (TCC) of the bladder. We provide a summary of the third expert meeting on 'Optimising the management of non-muscle-invasive bladder cancer, organized by the European Association of Urology Section for Uro-Technology (ESUT) in collaboration with the Section for Uro-Oncology (ESOU), including a systematic literature review. The article includes a detailed discussion on the current and future perspectives for TCC, including photodynamic diagnosis, optical coherence tomography, narrow band imaging, the Storz Professional Image Enhancement system, magnification and high definition techniques.

Postoperative infection rates in patients with a negative baseline urine culture undergoing ureteroscopic stone removal: a matched case-control analysis on antibiotic prophylaxis from the CROES URS global study.

Purpose: To examine the effects of antibiotic prophylaxis on postoperative infection rate in patients with negative urine cultures undergoing ureteroscopy (URS).

Patients And Methods: Using the Clinical Research Office of the Endourological Society (CROES) URS Global Study database, patients with a negative baseline urine culture undergoing URS for ureteral stones (n=1141) or kidney stones (n=184) not receiving antibiotic prophylaxis were matched with those who were predefined by risk factors, including gender, American Society of Anesthesiologists (ASA) score, and ureteral stent placement. Patient characteristics, operative data, and postoperative outcomes, including the development of urinary tract infection (UTI) and fever, in the two groups were compared.

Investigation of differences between nanosecond electropulse and electrohydraulic methods of lithotripsy: a comparative in vitro study of efficacy.

Purpose: To compare the effectiveness of novel nanosecond electropulse lithotripsy with standard electrohydraulic lithotripsy to demonstrate and authenticate their differences because both modalities appear to be similar.

Materials And Methods: An in vitro fragmentation study was conducted using cuboid BegoStone phantoms, which mimic hard and soft stones, based on an established model. Three different stone sizes were used in the testing having volumes of 100, 256, and 320 mm(3).

Comparative in vitro study of the effectiveness of nanosecond electrical pulse and laser lithotripters.

A comparative in vitro research of the efficiency of nanosecond electropulse (Urolit-105M) and Holmium laser (Auriga) lithotripters is presented in this work. Four sizes of BegoStone cement stones of various densities were fabricated for these tests. A comparison of the efficiency of the lithotripters was performed in the experiments on pairs of probes corresponding to a predetermined stone size.
