Retrieval of intrarenal coiled and ruptured guidewire by retrograde intrarenal surgery: A case report and literature review

Open Medicine, 2021
Foreign bodies in the kidney have rarely been reported. However, they can be a clinical problem for urologists. We report on a patient with a residual segment of guidewire coating embedded in the renal parenchyma following computed tomography (CT)-guided

Flexible and navigable suction access sheaths: balancing sheath and scope size for desired flows

BJU International, Volume 137, Issue S3, Page S60-S70, March 2026.
Objective To study the effects of ureteroscope diameter, ‘flexible and navigable suction’ access sheaths (FANS) diameter, and irrigation pressure on intrarenal pressure (IRP) and irrigation fluid flow rates in ex vivo porcine kidneys; these benchtop data were compared against mathematical modelling results.

Direct in‐scope suction (DISS) ureteroscopy: techniques, outcomes and future directions

BJU International, Volume 137, Issue S3, Page S19-S28, March 2026.
Objective To provide an overview of direct in‐scope suction (DISS) ureteroscopy, an emerging technology that integrates suction directly into the ureteroscope with the aim of enhancing stone clearance, improving visualisation, and reducing intrarenal pressure during ureteroscopic stone surgery.

Is stenting required before retrograde intrarenal surgery with access sheath

Indian Journal of Urology, 2009
Background: Flexible ureterorenoscopies continue to assume an increasing role in the armamentarium of the endourologist. In many centers around the world, prior stenting is carried out before retrograde intrarenal surgery (RIRS) to passively dilate the ...

Ultra‐Efficient Kidney Stone Fragment Removal via Spinner‐Induced Synergistic Circulation and Spiral Flow

Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.
Leveraging spinning‐induced localized suction, the spinner device enables ultra‐efficient removal of kidney stone fragments, capturing a larger quantity of fragments from distances exceeding 20 mm. The spinner significantly improves the efficiency and effectiveness of stone fragment removal by reducing operative time, increasing stone‐free rates, and ...

Does instrumentation and irrigation configuration affect intrarenal pressure during PCNL?

BJUI Compass, Volume 7, Issue 2, February 2026.
Abstract Objectives To measure the effects of varying configurations of nephroscope sheath, irrigation, instruments, and suction on intrarenal pressure (IRP) during percutaneous nephrolithotomy (PCNL). Materials and Methods Kidney and ureter 3D printed models from a deidentified patient's CT scan were placed in a plaster and foam mould, simulating the ...
