The aim of this paper was to evaluate the current technology and designs of flexible ureterorenoscopes. We will review contemporary fiberoptic and digital ureteroscopes, including a discussion on ureteroscope damage and repair, and lastly present the projected future of flexible ureterorenoscopy. Ureterorenoscopy has evolved dramatically over the past several decades, which has led to landscape reshaping of stone disease treatment and upper tract pathology. Advancements in tip control, miniaturization of scopes, introduction of a digital chip on the tip, disposable devices to augment surgery, surgical experience/familiarity and most recently single use scopes are all independent factors that have increased flexible ureterorenoscopy adoption and success...

We have read with interest the article recently published in the Journal of Endourology by Peplinski et al "The Effect of Laser Fiber Cleave Technique and Lithotripsy Time on Power Output". First, we agree with the conclusion of founding no benefit of using any specific cleaving technique. The authors did not include this parameter in their evaluations; this parameter is a key element in the experiments as the results might vary. Finally cleaving the laser fibers may bring other benefits: the fiber tip damage and cracking may allow back burns and retrograde laser emissions becoming a potential risk to damage the ureteroscope...

INTRODUCTION: The Nanopulse Lithotripter (NPL, Lithotech Medical, Israel) is a novel intracorporeal device that uses a nanosecond duration electrical discharge through a reusable flexible coaxial probe to endoscopically fragment urinary stones. This device was compared to a holmium laser lithotripsy (HoL) with regards to stone fragmentation efficiency (SFE) and its impact on flexible ureteroscope (URS) deflection and flow of irrigation. METHODS: Using a custom bench model, a 6mm Begostone cylindrical phantom (mixture 5:2) was confined under 0...

Over the past 2 decades, ureteroscopy has changed from a procedure considered second-line to shockwave lithotripsy to a commonly performed procedure for renal and ureteral stones. The increase in the use of ureteroscopy is due largely to improvements in technique and technology during this time period. Herein we review outcomes of ureteroscopy in terms of success rates, complications, and unique patient populations. This work will synthesize the data as it pertains to the practice of ureteroscopy for all endourological indications, including stone disease and management of upper tract urothelial carcinoma, as well as review state-of-the-art techniques...

The insertion of a double J catheter (DJ) has widespread, becoming a usual procedure and standard of care in urology. Despite its relative simplicity it is not free from intraoperative risks or problems during the weeks after the implant. Conversely, despite great advances in design of these catheters the ideal material has not been discovered yet, one that is perfectly biocompatible with urine and avoids completely the advent of complications. The range of problems associated with DJs is variable: from mild self-limited dysuria or hematuria to more complex situations with higher risk, such as catheter migration, complete calcification, breakage, obstruction and renal unit loss...

The use of double J catheters is usual in urologist's daily practice. The indication can be divided in prophylactic or therapeutic. Prophylactically, they prevent complications derived from endourological procedures, such as ureteral lesion or obstructive uropathy secondary to residual lithiasis or edema. Therapeutically, they treat obstructive uropathy of many different pathologies, either in an emergency setting or scheduled, such as lithiasis, stenosis, extrinsic compression of any nature or urinary tract tumors among others...

This case report explores the efficacy of simultaneous use of endourological and radiological methods to assess and manage high-grade renal trauma. A male rugby player was diagnosed with Grade 4 blunt renal trauma. A segment of the patient's kidney was isolated from the main renal pelvis with intact perfusion. This resulted in urinary extravasation. Ureteral stenting and angioembolization were used to treat the patient's severe symptoms. Angioembolization ablated functional tissue that was causing a persistent urinary leak...
