Construction of extended 3D field of views of the internal bladder wall surface: a proof of concept

, 2016
3D extended field of views (FOVs) of the internal bladder wall facilitate lesion diagnosis, patient follow-up and treatment traceability. In this paper, we propose a 3D image mosaicing algorithm guided by 2D cystoscopic video-image registration for ...

Piezo1 Channel Mediates Mechanically Programmable Drug Delivery to Potentiate Intravesical Chemotherapy

Advanced Science, EarlyView.
This study utilizes programmable mechanical pressure as a therapeutic enhancer to establish a mechano‐chemotherapy strategy. Controlled pressure activates the mechanosensitive ion channel Piezo1 in bladder cancer, triggering a calcium ion cascade that transiently and reversibly amplifies membrane permeability to chemotherapeutics.

How Can We Personalize the Delivery of Onabotulinumtoxin‐A for Patients With Neurogenic Lower Urinary Tract Dysfunction?

Neurourology and Urodynamics, EarlyView.
ABSTRACT Background & Aims Neurogenic lower urinary tract dysfunction (NLUTD) can produce bothersome urinary symptoms, impact quality of life, and in some cases, lead to deterioration of upper urinary tract function. Intradetrusor injection of onabotulinumtoxin‐A (BoNT‐A) is approved for NLUTD in patients who have an inadequate response to or ...

Cystoscopic extraction of an unusual intravesical foreign body: A case report

UroPrecision, EarlyView.
Abstract Background Foreign bodies (FBs) in the urogenital tract are considered surgical emergencies due to the risk of complications such as perforation, infection, and obstruction. FBs can be introduced into the urethra and migrate into the bladder. Various FBs, including pens, jump ropes, magnetic ball chains, and needles have been reported in the ...

Minimally invasive management of large seminal vesicle cyst in Zinner syndrome: Laser ablation for urinary retention

UroPrecision, EarlyView.
Abstract Background In Zinner syndrome (ZS), surgical intervention is recommended for pediatric patients with symptomatic disease. It is generally believed that cyst aspiration alone may lead to symptom recurrence. Although comprehensive surgical excision is often advocated to prevent recurrence, a combined approach of cyst aspiration and maximal cyst ...
