PURPOSE To examine short-term outcomes and complications in patients with a solitary kidney treated with irreversible electroporation (IRE) for a potentially malignant renal mass. MATERIALS AND METHODS Five patients (2 female, 3 male; mean age, 66 y) with 7 lesions who underwent IRE for renal tumors in a solitary kidney between August 2014 and August 2015(More)
BACKGROUND Ultrasound and fluoroscopy are the standard imaging techniques used to perform punctures in urology. Cross-sectional and three-dimensional (3D) imaging may enable safer procedures, especially in complex cases. OBJECTIVES To assess the feasibility of 3D planned laser-guided punctures in urology performed with the Uro Dyna-CT (Siemens Healthcare(More)
PURPOSE To determine whether previous transurethral resection of the prostate (TURP) compromises the surgical outcome and pathologic findings in patient who underwent either radical robot-assisted laparoscopic prostatectomy (RALP) or open retropubic radical prostatectomy (RRP) after TURP, because TURP is reported to complicate radical prostatectomy and(More)
BACKGROUND AND PURPOSE Fluoroscopy is used daily by endourologic surgeons worldwide without knowledge of received radiation doses. We wanted to assess the radiation exposure of endourologic surgeons by frequently performed endourologic interventions with an over-the-table x-ray system. PATIENTS AND METHODS In this prospective single-center study, 235(More)
Successful vaccination against intracellular pathogens requires the generation of cellular immune responses. Trehalose-6,6-dibehenate (TDB), the synthetic analog of the mycobacterial cord factor trehalose-6,6-dimycolate (TDM), is a potent adjuvant inducing strong Th1 and Th17 immune responses. We previously identified the C-type lectin Mincle as receptor(More)
OBJECTIVES Recent technical developments have facilitated the application of cone-beam computed tomography (CBCT) for interventional and intraoperative imaging. The aim of this study was to compare the radiation doses and image quality in CBCT with those of conventional multislice spiral computed tomography (MSCT) for abdominal and genitourinary imaging.

BACKGROUND Cervical selective nerve root block (CSNRB) is a well-established, minimally invasive procedure to treat radicular cervical pain. However, the procedure is technically challenging and might lead to major complications. The objective of this study was to evaluate the feasibility of a three-dimensional puncture planning and two-dimensional(More)
The objective of this study was to assess the functional efficacy of newly developed antirefluxive ureter stents (DJ), by performing immediate post-stenting cystograms on patients with acute ureteral obstruction requiring a DJ stent, and assessing stent-related symptoms by means of ureteral stent symptoms questionnaire (USSQ). Patients with acute(More)
BACKGROUND AND PURPOSE Transurethral laser enucleation of the prostate is a common therapeutic option for the treatment of benign prostate enlargement. Evacuation of the enucleated tissue from the bladder is usually performed by electric morcellators. Until now, a standardized evaluation of the different morcellator settings does not exist. Therefore, we(More)
OBJECTIVE To develop a standardized digital reporting tool for cystoscopy of the urinary bladder using panoramic imaging. MATERIALS AND METHODS An image processing and stitching software (Endorama) was developed to generate panoramic images from cystoscopy data. In a processing phase, algorithms were modulated and refined by reference to cystoscopy(More)
