OBJECTIVE To compare evolution in patients with urothelial upper tract tumor (UUTT) in whom we performed the classic open approach to the distal ureter with those in whom whe performed the endoscopic approach. We study the bladder recurrences in each group and the factors which may influx on the evolution. MATERIAL AND METHODS Retrospective review of nephroureterectomies in our department in ...

A laparoscopic guided technique of percutaneous chemical destruction of the gall bladder is described. The procedure entails the creation of a percutaneous access cholecystostomy for stone removal/fragmentation. After endoscopic occlusion of the cystic duct, the alkali corrosive, sodium carbonate was instilled into the gall bladder for 10-15 minutes. The treatment was applied in 11 animals with...

Study background: Several techniques exist to sculpt nasal septal cartilage grafts for use in functional and cosmetic rhinoplasty, including the use of cold steel, Bovie electrosection and the Sonopet ultrasonic bone aspirator. This is the first investigation on the effects of these disparate tools on gross cellular integrity of sculpted cartilage. Methods: After IRB approval, extraneous nasal ...

Hematuria due to locally advanced or metastatic bladder cancer is a common condition and is often a management problem. Percutaneous embolisation is a mini-invasive option to handle this situation. We report a case of a patient with a metastatic bladder cancer and who presented with an abundant hematuria and severe anemia. After failure of endoscopic resections and "flush" of radiotherapy haemo...

A foreign body near the bladder is rare. Although foreign bodies in the bladder can be easily found and removed by endoscopic transurethral removal, extravesical foreign bodies may require the use of an open or laparoscopic procedure. Here, we report a case of a patient complaining of frequency and urgency in whom an extravesical sewing needle was successfully removed by a laparoscopic approach...

Objective: To assess the safety and efficacy of bladder irrigation for reducing the morbidity of bladder stones in patients with neurological lower urinary tract dysfunction (NLUTD). Methods: From June 2012 to July 2013, patients with NLUTD were prospectively randomized and assigned to either a bladder irrigation group or a no bladder irrigation group. Bladder irrigations were performed twice a...

Introduction Bladder specimens received by pathologists commonly include endoscopic biopsy specimens and tissue from transurethral resections (TURB), both of which incorporate subepithelial tissues to a varying depth, as well as those resulting from cystectomy, cystoprostato-urethrectomy and pelvic exenteration. Less frequently seen are full thickness specimens of the bladder wall carried out a...

BACKGROUND There is paucity of data as to the results of the endoscopic approach in comparison to the golden standard of nephro-ureterectomy in elective, low grade TCC, patients. Our purpose is to report our results of a nephron sparing approach compared to nephro-ureterectomy in those patients. METHODS From a retrospective data base we identified 25 patients and 23 patients who underwent a n...

The aim of this review is to examine all urethral strictures and stenoses subsequent to treatment for prostate cancer, including radical prostatectomy (RP), radiotherapy, high intensity focused ultrasound (HIFU) and cryotherapy. The overall majority respond to endoscopic treatment, including dilatation, direct visual internal urethrotomy (DVIU) or bladder neck incision (BNI). There are adjunct ...

amyloidosis is a disorder of protein metabolism characterized by extracellular deposition of abnormal protein fibrils. it may either be localized to any organ or systematically distributed throughout the body. the biochemical nature of proteins varies but the physical and tinctorial properties are shared by all the amyloidogenic proteins. in the west, it is mainly composed of amyloid light (al)...
