"Valve"-Type Retainment of Flexible Ureteroscope in the Distal Ureter.

Flexible ureteroscopy (fURS) is an endoscopic procedure for the minimally invasive treatment of ureteral and renal calculi. Due to improvements in technique and ureteroscopic instrumentation over the past two decades, complications associated with URS are infrequent. However, in the event of an unexpected device malfunction or failure, the operating surgeon must employ prompt, resolute decision-making to resolve any intraoperative complications and avoid significant injury to the kidney or ureter.

Evaluation of the effect of Bernoulli maneuver on operative time during mini-percutaneous nephrolithotomy: A prospective randomized study.

Purpose: To evaluate the effect of 'Bernoulli maneuver' (bringing the access sheath to horizontal plane) on operative time and stone free rates in patients undergoing mini-percutaneous nephrolithotomy (PCNL).

Materials And Methods: All consecutive patients with a solitary kidney stone undergoing a mini-PCNL between 2015 and 2016 were included into this study. Patients were randomized either to standard prone or control (C) group patients or to tilted prone with 'Bernoulli maneuver' group (B) patients.

Ultrasound-Guided Ureteral Stent Removal in Women.

Objectives: The purpose of this study was to develop a fast, comfortable, and safe method of ureteral stent removal in women.

Methods: From February 2014 to July 2015, a retrospective multicenter controlled study including 82 female outpatients was conducted. The control group was composed of 46 patients who underwent stent removal using a 22F cystoscope.
