OBJECTIVE: To develop a standardized digital reporting tool for cystoscopy of the urinary bladder using panoramic imaging. MATERIALS & METHODS: An image processing and stitching software (Endorama(®)) was developed to generate panoramic images from cystoscopy data. In a processing phase, algorithms were modulated and refined by reference to cystoscopy sequences (n=30). Subsequently, standard systematic cystoscopies (n=12) were recorded in patients undergoing transurethral resection of a bladder tumor in order to create panoramic images...

OBJECTIVE: To determine the long-term impact of extravasation at initial post-urethroplasty urethrogram, we present a novel classification system and report the association of leak severity with outcome. MATERIALS AND METHODS: 91 patients underwent buccal graft urethroplasties of the bulbar urethra from 2007-2015. Median time to urethrogram was 23d. All leaks were characterized by length and width. Cutoffs for length and width were calculated using ROC curves. Each urethrogram was graded 0-3 (0=no leak) with one point given for any leak, length ≥1...

BACKGROUND: Plasmacytoid urothelial carcinoma (PUC) is a distinct variant of urinary bladder cancer, with a high propensity for invasion and poor prognosis. These tumors occur most commonly in male patients with the age of reported cases ranging from 46 to 87 years. CASE REPORT: We present a case of a 74-year-old male patient having massive ascites and bilateral lower leg edema. Colonoscopy showed a 3-cm lesion in the sigmoid colon and an edematous nonpapillary tumor was found by cystoscopy in the bladder...

INTRODUCTION: Double J (DJ) stents are often removed under local anesthesia using a rigid cystoscope. Patients experience significant pain during this procedure and also continue to have discomfort during voiding for a few days. We assessed the efficacy and safety of preemptive oral diclofenac in pain relief in patients undergoing DJ stent removal (DJSR) by rigid cystoscopy compared to placebo. METHODS: Consecutive consenting male patients undergoing DJSR under local anesthesia between March 2014 and July 2015 were enrolled...

INTRODUCTION: The artificial urinary sphincter (AUS) is the mainstay of surgical treatment for male stress urinary incontinence. Although urethral erosions are a known complication, their temporal distribution and optimal management have not been well characterized. We seek to evaluate the timing, etiologies, and management of urethral erosions in primary AUS implantations. MATERIALS AND METHODS: 1802 male patients underwent AUS procedure at Mayo Clinic (Rochester) from 1983 to 2011, including 1082 primary placements...

Urinary bladder paragangliomas are very rare, and the majority are hormonally active. Nonfunctioning paragangliomas are even rarer and more difficult to diagnose because of absence of catecholamine secretion. We present a 27-year-old woman with an asymptomatic paraganglioma of the urinary bladder discovered incidentally in a patient with prior resection of a functional pararenal paraganglioma. Metabolic profiles and cystoscopy were nondiagnostic. We demonstrate the increased sensitivity of I-MIBG SPECT/CT compared with planar scintigraphy for detection of a nonfunctional paraganglioma of the urinary bladder, which makes it valuable in evaluation of functional and nonfunctional paragangliomas...

PURPOSE: The majority of bladder cancer patients present with localized disease and are managed by transurethral resection. However, the high rate of recurrence necessitates lifetime cystoscopic surveillance. Developing a sensitive and specific urine-based test would significantly improve bladder cancer screening, detection, and surveillance. EXPERIMENTAL DESIGN: RNA-seq was used for biomarker discovery to directly assess the gene expression profile of exfoliated urothelial cells in urine derived from bladder cancer patients (n=13) and controls (n=10)...

Photodynamic diagnosis (PDD) of bladder tumour tissue significantly improves endoscopic diagnosis and treatment of bladder cancer in rigid cystoscopes in the operating theatre and thus reduces tumour recurrence. PDD comprises the use of blue light, which unfortunately excites green fluorescence from urine. As this green fluorescence confounds the desired red fluorescence of the PDD, methods for avoiding this situation particularly in cystoscopy using flexible cystoscopes are desirable. In this paper we demonstrate how a tailor made high power LED light source at 525 nm can be used for fluorescence assisted tumour detection using both a flexible and rigid cystoscope used in the outpatient department (OPD) and operating room (OR) respectively...

Prophylactic ureteric stenting in renal transplantation reduces major urological complications (MUCs). There is however morbidity related to the indwelling duration of a stent, we aimed to determine the optimal duration for stents in this clinical setting. Patients (aged 2-75 years) from 6 UK hospitals undergoing renal transplantation were recruited and randomly assigned, to either early stent removal at 5 days (without cystoscopy) or late at 6 weeks post-transplantation (with cystoscopy). The primary outcome was a composite of stent-related complications defined as pain, visible haematuria, migration, fragmentation, and urinary tract infections (UTIs) within 3 months of transplantation...

BACKGROUND AND AIMS: Advances in imaging technology have improved the annual detection rate of pancreatic cystic lesions, but the preoperative diagnosis of pancreatic cystic lesions remains unclear. Thus, the usefulness of single operator cholangioscopy (SOC) as a diagnostic imaging tool for pancreatic cystic lesions is worth investigating. We performed an intracystic visual examination of pancreatic cystic lesions using SOC to determine the diagnostic value of SOC for pancreatic cystic lesions...

A 23-year-old male patient was performed semirigid ureterorenoscopy and laser lithotripsy with placement magnetic DJ stent because of right urethral stone. Removal of the magnetic DJ stent does not need a second procedure such as cystoscopy for the patients. This technique is easy to learn and should be considered as suitable for use on an outpatient basis.

Background: The purpose of this case presentation is to demonstrate how erosion of mesh into the bladder can initially present with the same symptoms as bladder malignancy. Case Presentation: A 62-year-old Hispanic male presented with 2 years of hematuria along with imaging concerning for a bladder tumor. The patient underwent cystoscopy with biopsy of a lesion at the anterior bladder. It was ultimately determined that a mesh plug from a prior hernia repair had migrated into the bladder. The mesh plug was excised using the Da Vinci Si robot, which allowed for efficient mobilization of the bladder and other anatomic structures, as well as rapid recovery...

Traumatic urethral catheterization may result in a number of serious complications. A rare occurrence is the development of a urethral pseudoaneurysm. We report the case of a 13-year-old male who required placement of a Foley catheter for an orthopedic surgical procedure. The Foley was misplaced in the bulbourethra, resulting in the development of a bulbar artery pseudoaneurysm. Profuse bleeding via the urethra was noted after removal of the catheter, and the patient experienced severe intermittent hematuria during the postoperative period...

We report the case of a 40-year-old woman with a history of uterine polyps and 3 months worth of gross hematuria who was found to have a bladder mass on cystoscopy. While this mass appeared benign visually, it demonstrated enhancement on axial imaging with increased internal vascularity on Doppler ultrasound. A transurethral resection demonstrated bladder leiomyoma. This case increases the urologist's recognition of a well-described but previously under-represented condition by showcasing its visual appearance on cystoscopy...

Urologic pathology is evolving rapidly. Emerging trends include the expanded diagnostic utility of biomarkers and molecular testing, as well as adapting to the plethora of technical advances occurring in genitourinary oncology, surgical practice, and imaging. We illustrate those trends by highlighting our approach to the diagnostic workup of a few selected disease entities that pathologists may encounter, including newly recognized subtypes of renal cell carcinoma, pheochromocytoma, and prostate cancer, some of which harbor a distinctive chromosomal translocation, gene loss, or mutation...
