Comparison of lithotripsy methods during mini-PNL: is there a role for ballistic lithotripsy in the era of high-power lasers

open access: yesBMC Urology
Background For renal stones > 20 mm, percutaneous nephrolithotomy (PNL) offers the best stone clearance rates with acceptable complication rates. This study aimed to compare the efficiency of high-power holmium YAG laser and ballistic lithotripsy during ...

Experimental stone clearance with in‐scope suction and flexible and navigable suction access sheaths

open access: yesBJU International, Volume 137, Issue S3, Page S45-S52, March 2026.
Objective To perform benchtop experiments using direct in‐scope suction (DISS) ureteroscopes (Pusen Medical, Zhuhai, China; 3.6‐Ch and 5.1‐Ch working channels) and flexible and navigable suction (FANS) ureteric access sheaths (ClearPetra; Wellead, Guangzhou, China) to establish their ability to clear stones of different diameters.

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

open access: yesBJU 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.

Coexistence of multiple ureteral and ureterocele stones in a patient

open access: yesAfrican Journal of Urology, 2020
Background Uroterocele causes atony and stagnation in the ureter, thus predisposing the patient to stone formation. Multiple calculi in uroteroceles are common in adults but very rare in children.

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

open access: yesBJU 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.

Laser Lithotripsy — The New Wave

open access: yesCanadian Journal of Gastroenterology, 1990
Currently more than 90% of all common bile duct concrements can he removed via the endoscopic retrograde route by means of endoscopic papillotomy, stone extraction by baskets and balloon catheters, or mechanical lithotripsy.

Benchtop comparison of seven ureteroscopes: evaluating physical properties and deflection with flexible and navigable suction access sheaths

open access: yesBJU International, Volume 137, Issue S3, Page S86-S92, March 2026.
Objectives To evaluate the physical properties of seven ureteroscopes (URSs) and compare the maximal angle of deflection (MAD) when used with flexible and navigable suction access sheaths (FANSs) of varying sizes. Materials and Methods Seven commercial URSs (ranging from 6.3 to 9.5 F in size) were evaluated for outer diameter, irrigation flow rate ...
