“…Methods for the evacuation of small residual fragments include the glue-clot technique and irrigation/suction systems. In the glue-clot technique, autologous venous blood is injected into a calyx, where it agglutinates with stone fragments to form a clot that can be extracted with a basket [38]. In a randomized pilot study of 47 patients, an automated irrigation/suction pump system was tested and found to reduce mean operating time by 35% (p = 0.04) and to increase SFR from 69 to 92% (p = 0.048) compared with the standard pressurized technique [39].…”

Purpose To summarize current knowledge on intracorporeal laser lithotripsy in flexible ureterorenoscopy (fURS), regarding basics of laser lithotripsy, technical aspects, stone clearance, lithotripsy strategies, laser technologies, endoscopes, and safety. Methods A scoping review approach was applied to search literature in PubMed, EMBASE, and Web of Science. Consensus was reached through discussions at the Consultation on Kidney Stones held in September 2019 in Copenhagen, Denmark. Results and conclusions Lasers are widely used for lithotripsy during fURS. The Holmium laser is still the predominant technology, and specific settings for dusting and fragmenting have evolved, which has expanded the role of fURS in stone management. Pulse modulation can increase stone ablation efficacy, possibly by minimizing stone retropulsion. Thulium fibre laser was recently introduced, and this technology may improve laser lithotripsy efficiency. Small fibres give better irrigation, accessibility, and efficiency. To achieve optimal results, laser settings should be adjusted for the individual stone. There is no consensus whether the fragmentation and basketing strategy is preferable to the dusting strategy for increasing stone-free rate. On the contrary, different stone scenarios call for different lithotripsy approaches. Furthermore, for large stone burdens, all laser settings and lithotripsy strategies must be applied to achieve optimal results. Technology for removing dust from the kidney should be in focus in future research and development. Safety concerns about fURS laser lithotripsy include high intrarenal pressures and temperatures, and measures to reduce both those aspects must be taken to avoid complications. Technology to control these parameters should be targeted in further studies.

“…65 The autologous blood clot technique was first applied in 2008 as a method to occlude lower calyx during RIRS and later extended to the removal of small fragments, entrapping and removing them using the coagulum. 75 However, visibility during the procedure was clearly affected by the use of blood and so it was clear that better materials were needed for biocompatibility and efficacy in incorporation of RFs. 74 Biocompatible glue was developed for this purpose.…”

Stone residual fragments: A thorny problem

et al. 2019

Urolithiasis represents a widespread and common disorder among the world population, with a predicted increase in affected patients in the coming years. Treatment of renal and ureteral stones varies widely, and achieving true stone-free status in all patients is still difficult. Moreover, imaging used to assess residual fragments following procedure impacts the diagnosed stone-free rate percentage considerably. In particular, the use of computed tomography scans has led to a better evaluation of residual fragments as well as so-called clinically insignificant residual fragments, which in a considerable number of cases are, despite their definition, causes of adverse urological events, thus creating a thorny problem for both patients and urologists. Currently, there is no gold standard or validated protocol regarding the management, clearance and prevention of residual fragments. In this article, we review the current literature regarding residual fragments, clinically insignificant residual fragments and their natural history, reporting on diagnostic methods, incidence, complications and outcome with the use of less invasive procedures, taking into consideration viable treatment and management of patients affected.

ZusammenfassungDie flexible Ureterorenoskopie (fURS) kann als „urotechnologische“ Erfolgsgeschichte bezeichnet werden. Seit der Einführung der fURS in die Harnsteintherapie wurde diese immer weiter technisch verbessert, was zu exzellenten klinischen Ergebnissen bei niedrigen Komplikationsraten führte. In den letzten Jahren prägte insbesondere die Einweg-Ureterorenoskopie die Landschaft der urologischen Endoskopie. Bei genauerer Betrachtung ist diese Entwicklung jedoch keine genuine Innovation, sondern vielmehr eine weiterführende Optimierung, die primär zur Vereinfachung innerbetrieblicher Abläufe (keine Sterilisation, keine Reparaturen) sowie zur Verhinderung der Keimübertragung bei insuffizient aufbereiteten Arbeitskanälen führt. Neue Technologien wie eine automatisierte Laserlithotripsie, intrarenale Temperatur- und Druckmessung warten noch auf ihre Markteinführung und den Einsatz bei der fURS. Diese hätten das Potenzial die endoskopische Steintherapie einen weiteren entscheidenden Schritt voranzubringen.
