Cystoscopy Articles

In this paper, current guidelines regarding diagnostic and staging modalities of urothelial cancer of the bladder are summarized and an overview of endoscopic, imaging, and molecular methods currently being tested are outlined.

Schedules for the follow-up (FU) of bladder cancer patients are predominantly based on studies with low level of evidence and the resulting guidelines' recommendations that are often founded on expert consensus.

Local anesthesia using urethral gel has been proven to reduce discomfort of male patients during flexible cystoscopy. This study was a non-inferiority study between two lidocain-containing urethral gel (Instillagel(®) Lido and Xylocaine(®) gel).

Transitional cell carcinoma of the bladder, the second most common urologic malignancy, is amenable to early diagnosis. This study presents the potential prognostic benefit for a less invasive modification to the standard endoscopic approach.

Introduction: The methods employed to document cystoscopic findings in bladder cancer patients lack accuracy and are subject to observer variability. We propose a novel endoimaging system and an online documentation platform to provide post-procedural 3D bladder reconstructions for improved diagnosis, management and follow-up.

Determine if "bag-squeeze" technique decreases pain during flexible cystoscopy in men.

A single center, prospective, double-blinded randomized controlled trial recruiting 200 consenting participants who were ambulatory, outpatient males who had undergone a prior cystoscopy and were not expected to require any secondary procedures.

The vast majority of patients who undergo a diagnostic evaluation for microscopic hematuria (MH) do not have occult bladder cancer. Identifying patients with MH at high risk of harboring bladder cancer can allow for a risk adjusted approach to diagnostic interventions with the goal of safely reducing unnecessary evaluations.

Surveilling recurrent urothelial carcinoma (UC) requires frequent cystoscopy, which is invasive, expensive and time-consuming. An accurate urinary biomarker has the potential to reduce the number of cystoscopies required during post-treatment surveillance.

PURPOSE - To prospectively assess anxiety and depression in patients undergoing diagnostic cystoscopy.

METHODS - Patients presenting for outpatient diagnostic cystoscopy were recruited from four European urological departments.

Adequate tumor detection is critical in complete transurethral resection of bladder tumor (TURBT) to reduce cancer recurrence, but up to 20% of bladder tumors are missed by standard white light cystoscopy.

Correct cystoscopy images classification depends on interpreter's experience. Bladder cancer is a common lesion that can only be confirmed by biopsying the tissue, wherefore the automatic identification of tumors has a significant role in the early stage diagnosis and its accuracy.

In order to expand the availability of cystoscopy to underserved areas we have proposed utilizing advanced practice providers (APPs) to perform cystoscopy with real-time interpretation by the urologist on a telemedicine platform, termed "tele-cystoscopy".

Urinary biomarkers are needed to improve the management and reduce the cost of urothelial bladder cancer (UBC); however, none have been recommended yet for clinical practice.

To investigate the clinical performance of a new mRNA-based urine test, aiming to avoid unnecessary follow-up cystoscopy in patients under active surveillance (AS) for recurrent NMIBC.

This is a prospective cohort study enrolling patients with history of low-grade (LG) NMIBC, who developed a recurrence during the follow-up and underwent AS.

Screening for bladder cancer in patients with neurogenic lower urinary tract dysfunction is a challenge. Cystoscopy alone is not sufficient to detect bladder tumors in this patient group. We investigated the usefulness of combined cystoscopy and urine cytology.

OBJECTIVE - To determine the role of computed tomography-virtual cystoscopy (CT-VC) in the detection and evaluation of bladder cancer, compared to standard conventional cystoscopy (CC).

PATIENTS AND METHODS - Twenty-five patients with a clinical presentation of a bladder mass(es) were selected from an outpatient urology clinic between May 2011 and August 2012.

One of the most reliable methods for diagnosing bladder cancer is cystoscopy. Depending on the findings, this may be followed by a referral to a more experienced urologist or a biopsy and histological analysis of suspicious lesion.

There is an ongoing debate on panurothelial changes in the upper and lower urinary tract as multifocal presentation of urothelial cancer is well recognised. Concurrent bladder cancer impacts the outcome of the upper urinary tract urothelial cancer treatment, while its detection still relies on the white light cystoscopy.

Urologists often insist on sterile urine before invasive outpatient urological procedures, and urine culture and antibiotics are usually given before cystoscopy or instillation of bacille Calmette-Guérin (BCG) therapy, especially in patients who have positive urine cultures.

To determine if self-visualization of ambulatory cystoscopy provides a decrease in pain perception in male and female patients.

A quasi-randomized controlled trial involving patients scheduled for ambulatory cystoscopy from August to November 2017.

Midurethral slings are the mainstay of treatment for stress urinary incontinence. The role of cystourethroscopy to detect lower urinary tract injury following retropubic midurethral slings is well-established; however, its role following transobturator or single-incision sling placement remains controversial.

A 90-year old man with no significant past medical history presented to urology clinic complaining of gross hematuria, urinary frequency, and dysuria. Previous urine cytology was atypical but two white-light cystoscopies failed to show any lesions.

Objectives: To evaluate if the use of a photographic handbook (PH) can be a useful tool to improve the detection of disorders during cystoscopy training, as several hands-on tools have been proposed to improve technical skills but very few aim to improve specificity and sensitivity.

To determine diagnostic accuracy of NMP 22 and urine cytology in the detection of transitional cell carcinoma (TCC) urinary bladder taking cystoscopy as a gold standard in patients having provisional diagnosis of bladder cancer (BC).

To report the incidence of urinary tract malignancies (UTM) and to compare the diagnostic accuracy of cytology with cystoscopy, renal ultrasound (US) and computed tomography (CT) in patients with hematuria.

To develop a standardized digital reporting tool for cystoscopy of the urinary bladder using panoramic imaging.

An image processing and stitching software (Endorama(®)) was developed to generate panoramic images from cystoscopy data.

STOCKHOLM, SWEDEN (UroToday.com) - In this session, Dr. B.W.G. Van Rhijn presented a state-of-the-art lecture on the use of urinary markers in patients with bladder cancer.

This paper aims to evaluate the influence of quality of transurethral resection in patients with non-muscle invasive bladder cancer on the benefit of fluorescent cystoscopy-assisted transurethral resection in the post hoc analysis of the single-center randomized controlled trial.

Endoscopy coupled with targeted resections represents a cornerstone in the diagnosis, staging, and treatment of patients with bladder cancer. Direct visualization can be challenging and imprecise due to patient-, tumor-, and surgeon-specific factors.

To update current recommendations on prevention, screening, diagnosis, and evaluation of bladder cancer (BC) based on a thorough assessment of the most recent literature on these topics.

A non-systematic review was performed, including articles until June 2017.

This overview presents the updated European Association of Urology (EAU) guidelines for non-muscle-invasive bladder cancer (NMIBC), TaT1, and carcinoma in situ (CIS).

To provide practical recommendations on the clinical management of NMIBC with a focus on clinical presentation and recommendations.

The most commonly performed procedure among urologists is cystoscopy. However, urologists in developing countries have limited access and funds to purchase the equipment necessary to perform this procedure.

Bladder cancer (BC) is one of the most common cancers worldwide. BC diagnosis and surveillance is based on cystoscopy (CS). CS impact on patient's depression, anxiety, and sexual satisfaction (SS) is not sufficiently studied.

The purpose of this study is to determine whether a transvaginal trigonal block immediately preceding cystoscopy with hydrodistention yields an additional therapeutic benefit compared to cystoscopy with hydrodistention alone for the treatment of bladder pain syndrome/interstitial cystitis (BPS/IC).

The applicability of cystoscopy follow-up protocol that is indicated for low-risk nonmuscle-invasive bladder cancer (NMIBC) in the guidelines was investigated for our population.

Patients who underwent transurethral resection with a diagnosis of primary bladder tumor in our clinic within 10 years with low grade of pathology pTa and follow-up periods of at least 5 years were retrospectively reviewed.

This presentation considers follow-up after successful transurethral resection of a high-grade non-muscle-invasive tumour, with normal cystoscopy, followed by bacillus-Calmette-Guérin (BCG) therapy.

Bladder cancer is one of the most common malignant tumors in humans. Over the last several years, a significant problem has been observed related to the diagnosis and treatment of bladder cancer. Research is underway on diagnostic and therapeutic methods that aim to reduce rates of recurrence and progression of bladder cancer.

It has been suggested that the frequency of micronuclei (MN) in defoliated urothelial cells could be used as a biomarker for both the potential risk of bladder cancer (BC) and its progression. To prove this we have carried out a large study evaluating the MN frequency in a group of 383 hospital patients submitted to cystoscopy.

Various imaging modalities can be used in addition to white light (WL) to improve detection of bladder cancer (BC).

To use real-time multispectral imaging (rMSI) during urethrocystoscopy to combine different imaging modalities to achieve multiparametric cystoscopy (MPC).

Despite being one of the most common cancers, bladder cancer is largely inefficiently and inaccurately staged and monitored. Current imaging methods detect cancer only when it has reached "visible" size and has significantly disrupted the structure of the organ.

With high morbidity and mortality, urinary bladder cancer (BC) ranks fifth among common cancers globally. The inherent limitations of urine cytology and cystoscopy, and marginal enhancements in the rate of survival promt us to develop surrogate serum based metabolic biomarkers of screening, identification, and follow-up protocols of management for BC patients.

A 52-year-old man complains of minor urgency and frequency during the day and nocturia × 3-5. His DRE reveals a 30-g benign prostate. He is started on tamsulosin, and his daytime symptoms resolve entirely; however, he still has nocturia × 2-4.

National guidance in the UK continues to recommend urgent referral of selected patients with non-visible haematuria for urological assessment. The positive predictive value of non-visible haematuria for urological cancer is low, so it is uncertain whether this is an effective and equitable use of healthcare resources.

To evaluate overactive bladder (OAB) symptoms in patients undergoing diagnostic cystoscopy. Overall changes in the entire study population were assessed, as well as broken down by various subgroups.

Photodynamic diagnosis increases the detection rate and hence decreases recurrence rates of urothelial cancer (UC) of the bladder. This technique has been implemented in the upper urinary tract and like in the bladder, has shown to increase the detection rate of urothelial lesions.

To evaluate the preclinical and clinical performance of a pivoting lens rigid endoscope Endocameleon®, (ECAM) in white light cystoscopy (WLC).

Preclinical evaluation was performed ex vivo in CT-based, anatomically correct and validated bladder phantoms.

To identify factors that impact on the timeliness and adequacy of haematuria evaluation.

We undertook a retrospective cohort study identifying patients who underwent cystoscopy for investigation of haematuria at our institution between 1 January 2015 and 31 December 2015.

Objectives To compare postoperative infectious outcomes of bladder biopsies performed in the office without antibiotic prophylaxis versus those done with preoperative antibiotic prophylaxis in the operating room.
