Latest publications state equal efficacy of a recently introduced new percutaneous technique (“ultra-mini PCNL”, UMP) and flexible ureteroscopy (fURS) in the treatment of medium-size urinary stones. Today we face challenges concerning cost-effectiveness and reduction of in-hospital length of stay. In this retrospective study, we compare clinical outcome(More)
To compare ultra-mini PCNL (UMP) and flexible ureteroscopy (fURS) for the treatment of medium- to large-sized renal stones with a focus on patients’ postsurgical cumulative analgesic consumption and treatment-related satisfaction. Twenty-five patients treated by UMP between April 2013 and October 2014 were matched to data of 25 fURS patients from an(More)
OBJECTIVE To evaluate the diagnostic accuracy of a new energy and radiation dose-reduced protocol for noncontrast computed tomography (NCCT) with dual-energy CT (DECT) analysis and its potential for the compositional analysis of uric acid (UA)- or non-uric acid (N-UA)-containing calculi. METHODS A retrospective evaluation was carried out in 61 patients(More)
THE PROBLEM The demographic development of society leads to an increased demand for physicians. Particularly in the surgical disciplines, there is a noticeably declining interest among graduates from medical schools worldwide. For reasons discussed in detail, this applies especially to urology. SOLUTIONS We indicate possibilities on how to counteract this(More)
OBJECTIVE To evaluate the predictive power of the objectivation of the phimosis grade according to the classification defined by Kikiros and Woodward, with regard to the expected efficacy of 0.1% betamethasone cream as a treatment option. METHODS From October 2010 to May 2011, a total of 55 boys (aged <10 years) were treated for phimosis at our(More)
OBJECTIVE To present a unique completely standardized sequence of steps performed before, during, and after flexible ureteroscopy (FURS) that achieves superior results for FURS treatment of renal calculi. MATERIALS AND METHODS The "Freiburg FURS technique" includes the following steps: (a) preoperative ureteral stenting; (b) placement of 2 hydrophilic(More)
BACKGROUND AND PURPOSE Objective parameters for the classification of ureteral injuries and resulting indications for ureteral stent placement after ureteroscopy are lacking. We hereby present a new classification system including proof of interrater reliability and validation of recommendations for postoperative ureteral stent placement. PATIENTS AND(More)
Different types of single-incision laparoscopic surgery (SILS) have become increasingly popular. Although SILS is technically even more challenging than conventional laparoscopy, published data of first clinical series seem to demonstrate the feasibility of these approaches. Various attempts have been made to overcome restrictions due to loss of(More)
The Post-Ureteroscopic Lesion Scale (PULS) offers a simple grading system for the description of ureteral lesions after ureteroscopy. In this article, we present the results of a video-based multicenter evaluation of the inter-rater reliability of clinically important PULS grades 0–3. Video sequences at the end of ureteroscopy (final passage) were recorded(More)
OBJECTIVE To assess stone-related events (SREs) requiring retreatment in a series of 100 consecutive patients treated by retrograde intrarenal surgery (RIRS) for renal stones and to evaluate potential risk factors thereof. PATIENTS AND METHODS The primary outcome was incidence of SRE (medical or surgical treatment). Secondary outcomes included side of(More)
