Purpose: OnabotulinumtoxinA (BTX) detrusor chemodenervation is an efficacious third-line treatment for overactive bladder. Despite high clinical efficacy rates for BTX injection, many patients refuse initial or repeat treatment due to the invasiveness of the cystoscopic route of delivery. We assess the feasibility of injecting the trigone and posterior bladder wall via a transvaginal route under ultrasound guidance using a human cadaveric model. Materials and Methods: Eight de-identified anonymous fresh female deceased donor cadaver pelvises were placed in supine split leg position...

Multi-parametric magnetic resonance imaging (mpMRI) has been increasingly used to diagnose clinically significant prostate cancer (csPCa) because of its growing availability and its ability to combine anatomical and functional data. Magnetic resonance imaging (MRI)-transrectal ultrasound (TRUS) fusion imaging provides MRI information with TRUS images for prostate biopsies. This technique combines the superior sensitivity of MRI for targeting suspicious lesions with the practicality and familiarity of TRUS. MRI-TRUS fusion image-guided prostate biopsy is performed with different types of image registration (rigid vs...

Endoscopic combined intrarenal surgery (ECIRS) with simultaneous retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) has been proposed as a new surgical treatment to overcome the disadvantage of RIRS and PCNL monotherapies in the treatment of renal stone. One of advantages of ECIRS is that it can increase stone-free rates in complex renal stone within single-session. Intermediate-supine position in real-time simultaneous ECIRS can prevent an anesthesiologic problem, and patient's burden is small even for long-term operation...
