The dilemma of 12/14F ureteral access sheath (UAS) usage: a case control study.

Background: The insertion of a ureteral access sheath (UAS) is a frequent procedure during flexible ureteroscopy (fURS) to facilitate kidney stone treatment. The aim of this study was to investigate the influence of 12/14 French (F) UAS on fURS outcomes.

Methods: We performed a retrospective monocentric analysis of fURS procedures conducted at the Department of Urology (University Hospital Schleswig-Holstein, Lübeck, Germany) for kidney stone treatment via lithotripsy or basket stone retrieval between September 2013 and June 2017.

Risk Factors for a Complicated Postoperative Course in Flexible Ureteroscopy.

Introduction: The goal was to determine risk factors for Clavien-Dindo (CD) grade ≥2 complications, with special focus on early postoperative systemic inflammatory response syndrome (SIRS), for flexible ureteroscopy (fURS).

Materials And Methods: A retrospective monocentric statistical analysis relating to 32 factors was performed with the χ2 test, Mann-Whitney U tests, and multivariate logistic regression.

Results: In total, 416 consecutive fURS performed between September 2013 and June 2017 were analyzed; 283 (68.

[Surgical treatment of pulmonary metastases in metastatic renal cell carcinoma].

Between 20 and 30 % of patients diagnosed with renal cell carcinoma suffer from metastatic disease by the time of diagnosis and a further 20 - 30 % develop metachronous metastases after initial treatment with curative intent. The therapeutic landscape of metastatic renal cell carcinoma seems be changing rapidly, with new systemic therapies or combination therapies available and established concepts being questioned because of long-awaited data. Apart from systemic therapy, metastases can be treated by surgical resection.

Laser fibre, rather than the stone, may harm the scope: retrospective monocentric analysis of 26 pre- and intraoperative factors of flexible ureteroscope (fURS) damage.

Purpose: The increasing number of flexible ureteroscopy procedures, the fragility of devices and their repair costs are a burden for urological departments worldwide. The objective was to investigate the impact of 26 pre- and intraoperative factors on reusable flexible ureteroscope (fURS) damage.

Methods: All procedures were conducted with reusable fURS: Karl Storz Flex-X2 or Olympus URF-V.

[Symptomatic renal tumours in metastatic renal cell carcinoma - surgical options].

Between 15 and 20 % of patients diagnosed with renal cell carcinoma suffer from metastatic disease by the time of diagnosis. In addition to systemic therapy, there are various surgical strategies to treat the primary tumour, e. g.

Steep Infundibulopelvic Angle as a New Risk Factor for Flexible Ureteroscope Damage and Complicated Postoperative Course.

Objective: The increasing number of flexible ureterorenoscopy (fURS) procedures, the fragility of devices, and their growing repair costs represent a substantial burden for urological departments worldwide. No risk factors of flexible ureteroscope damage have been identified so far. The objective of this study was to investigate the impact of infundibulopelvic angle (IPA) on device damage and on other intraoperative and postoperative factors such as length of hospital stay, surgical complications, stone-free rate (SFR), operation, and fluoroscopy time.
