Magnetic resonance visual cystoscopy or MR cystography (MRC) is an emerging tool for bladder tumor detection, where three-dimensional (3D) endoscopic views on the inner bladder surface are being investigated by researchers. In this paper, we further investigate an innovative strategy of visualizing the inner surface by flattening the 3D surface into a 2D display, where conformal mapping, a math...

BACKGROUND Transurethral resection of bladder tumor (TURBT) technique has been considered the routine method for removing most bladder tumors for decades. In contrast, endoscopic submucosal dissection (ESD) is the gold-standard treatment for gastrointestinal superficial tumors. We investigated the effectiveness and applicability of a new technique for en bloc bladder tumor resection using ESD p...

Ureteral urothelial tumors (UUT) are uncommon; their incidence is higher in areas affected by Balkan endemic nephropathy (BEN), with low-grade lesions prevalent. In these patients, the efficacy of conservative surgery is comparable to that of nephroureterectomy. Endoscopic treatment is indicated for single, small and low grade UUT, in older patients with significant comorbidity. The case of an ...

Received April 2006 Accepted October 2006 INTRODUCTION Foreign bodies in the bladder can result in recurrent urinary tract infection (UTI), hematuria, calculus formation, and pelvic pain.(1) Instruments used for surgical and endoscopic procedures or masturbation may migrate into the bladder. Intrauterine device (IUD) is a safe and cost-effective means of contraception.(2) However, since its app...

Background: the Mitrofanoff appendicovesicostomy provides a catheterizable submucosal tunnel between umbilicus and bladder (or neobladder). In patients with closed neck, channel is only way to access bladder. We describe our case of 17 year-old girl previous surgical closure neck who developed large clot due hematuria after cystolithotomy in an augmented bladder; Methods: unsuccessful trans-app...

We describe our experience in using a new endoscopic technique for suspending the bladder neck and urethra in 16 patients with stress incontinence. The procedure was started by dissecting the retropubic space, first with a sound and then with a Foley catheter before passing an absorbable suture from the abdominal fascia to the bladder neck using an elbowed needle introduced into the bladder thr...

Bladder cancer is widely spread in the world. Many adequate diagnosis techniques exist. Video-endoscopy remains the standard clinical procedure for visual exploration of the bladder internal surface. However, videoendoscopy presents the limit that the imaged area for each image is about nearly 1 cm. And, lesions are, typically, spread over several images. The aim of this contribution is to asse...

BACKGROUND Posterior urethral valves (PUV) may cause subtle to severe obstruction of the urethra, resulting in a broad clinical spectrum. PUV are the most common cause of chronic renal disease in boys. Our purpose was to report the incidences of kidney and bladder dysfunction in boys treated with endoscopic valve resection for PUV. METHODOLOGY We searched MEDLINE and EMBASE databases until 1s...
