Although signet-ring cell (SRC) adenocarcinoma is commonly seen in the stomach, it is a very rarely seen histologic entity in the bladder. It is difficult to distinguish primary SRC adenocarcinoma of the bladder from bladder metastasis of SRC carcinoma of the stomach only based on histological findings. In such cases, clinical findings and immunohistochemical studies may be helpful. We present ...

Primary non-Hodgkin's lymphoma (NHL) of the bladder is a very rare entity. The clinical, radiological and endoscopic signs are not specifics. The diagnosis is exclusively histological. Chemotherapy, radiotherapy and surgery are the different therapeutic options used either alone or in combination. We report a 57 years old patient treated with chemotherapy (6 cycles of R-CHOP) for primary NHL of...

BACKGROUND AND OBJECTIVES In this retrospective study, nature, clinical presentations, diagnostic modalities, and endoscopic treatment of urinary system foreign bodies were evaluated. METHODS A total of 8 cases were treated with endoscopic surgery between February 15, 2007 and June 12, 2012. Clinical findings, radiologic diagnosis, and management were reviewed. RESULTS We observed that urin...

A 56-year-old woman with irritative voiding symptoms and recurrent urinary infections was found to have erosion into the bladder of a tension-free vaginal tape placed 61 months before. To achieve radical excision, a 26Fr Amplatz sheath was placed suprapubically under endoscopic vision. A rigid nephroscope with grasping forceps was used to pull the eroded mesh out of the bladder wall while excis...

Chondroma is a benign tumour of mesenchymal origin that is composed of cartilage and rarely located in soft tissues, being described so far only in four cases, as located in the bladder, according to our knowledge. We describe the fifth case of a 67-year-old woman who consulted for microscopic haematuria, with an endoscopic finding of submucosal nodular image in the anterior wall of the bladder...

INTRODUCTION Transurethral Resection of Bladder Tumors (TURBT) can be a challenging procedure, primarily due to limitations in tool-tip dexterity, visualization and lack of tissue depth information. A transurethral robotic system was developed to revolutionize TURBT by addressing some of these limitations. The results of three pilot in-vivo porcine studies using the novel robotic system are pre...

Ureteral fibroepithelial polyps are rarely seen benign tumors with mesodermal origin. These polyps can involve kidney, pelvis, ureter, bladder, and urethra. The most common symptoms are hematuria and flank pain. The choice of treatment is either endoscopic or surgical resection of polyp by sparing kidney. Here, we presented a pediatric case with giant, fibroepithelial polyp that mimics bladder ...

This review provides an overview of emerging techniques, namely, photodynamic diagnosis (PDD), narrow band imaging (NBI), Raman spectroscopy, optical coherence tomography, virtual cystoscopy, and endoscopic microscopy for its use in the diagnosis and surveillance of bladder cancer. The technology, clinical evidence and future applications of these approaches are discussed with particular emphas...

INTRODUCTION Most bladder stones develop in patients with bladder outlet obstruction. Intravesical stone formation after surgery outside the urinary bladder is rare. CASE PRESENTATION A 54-year-old Taiwanese woman with lower urinary tract symptoms following a hysterectomy 14 years ago presented to our hospital. The intravesical calculus had developed from non-absorbable sutures and hung on th...

Chin J Cancer Res 2014;26(6):644-646 www.thecjcr.org Endoscopic techniques in gastroenterology have been developing rapidly over the past two decades. Advances in minimally invasive endoscopic techniques allow for the detection and treatment of more gastrointestinal (GI) diseases than ever. In a manner of speaking, the advent of miniature ultrasound device coupled with endoscopy further shapes ...
