PURPOSE Tissue diagnosis of upper tract urothelial carcinoma (UTUC) is limited by variance in tumor sampling by standard ureteroscopic biopsy. Optical imaging technologies can potentially improve UTUC diagnosis, surveillance, and endoscopic treatment. We previously demonstrated in vivo optical biopsy of urothelial carcinoma of the bladder using confocal laser endomicroscopy (CLE). In this study...

INTRODUCTION Secondary bladder neck sclerosis (BNS) represents a common late complication of prostate surgery, however so far insufficiently assessed in the available literature. More over, the previously attempted and analyzed therapeutic modalities failed to achieve acknowledgement as standard treatment for this particular pathology. METHODS The bipolar plasma vaporization (BPV) was introdu...

Endoscopic sphincterotomy (ES) was attempted in 106 patients with common bile duct (CBD) calculi and gall bladders present, who were considered unfit for surgery on the grounds of age and frailty alone (35%) and/or the presence of major medical problems (65%). Endoscopic sphincterotomy was successful in 105 patients (99%). Early ES related complications occurred in 21 patients (19.8%). Twelve h...

Introduction. Vesicovaginal fistula has been a social and surgical problem for centuries. Many surgical techniques have been developed to correct this abnormality, including transabdominal, transvaginal, and endoscopic approaches. The best approach is probably the one with which the surgeon feels most experienced and comfortable. Laparoscopy has become increasingly popular in urology, reducing ...

Prostate cancer is the second most commonly diagnosed malignancy in men worldwide. The prevalence has been increasing with significant differences between regions. This study assesses of incidental prostate detected specimens removed during bladder outlet obstruction operation. A retrospective analysis records patients who had either endoscopic or open prostatectomy from January 1998 to Decembe...

Pleomorphic carcinomas are primary malignant tumours that are known to arise in the lungs, pancreas, gall bladder and intestine. A patient with polypoid tumour of the esophagus is described in this report. The patient presented with dysphagia. Diagnostic and therapeutic intervention required endoscopic evaluation and treatment. Benign esophageal tumours are rarely seen and originate from the up...

Achieving photoacoustic microscopic imaging through a miniaturized scanning head is a crucial step toward high-resolution photoacoustic endoscopy. In this work, we have developed a miniaturized probe head using a microelectromechanical systems (MEMS) based mirror for raster scan of the laser beam and our newly developed super broad bandwidth microring resonator based ultrasound detector for pho...

OBJECTIVE To establish the utility of endoscopic sclerotherapy using 1% ethoxysclerol for the control of intractable hematuria following post-irradiation telangiectatic cystitis (PTC). METHODS Our experience of treating 4 patients (one female and three male) with massive exsanguinating hematuria resulting from PTC, using a combined intralesional and perilesional injection of 1% ethoxysclerol,...

Cystectomy is the gold standard treatment for patients with bladder cancer. Urinary diversion with ileal conduit and uretero-ileal anastomoses, as described by Bricker, is the most widely used surgical therapy because of the lower risk of postoperative complications in elderly patients and in those with co-morbidities. The Bricker technique involves the use of a segment of the ileum as a condui...

OBJECTIVE To assess the effectiveness of different treatment modalities for benign ureteric strictures. SETTING Department of Urology, Al-Emiri Hospital, Kuwait. PATIENTS AND METHODS Twenty four cases (19 unilateral and 5 bilateral) of ureteral strictures were reviewed. Retrograde endoscopic dilatation was tried, initially for all of the strictures. Technical failure was observed in 8/29 (2...
