This paper presents a magnetic resonance imaging (MRI)-based virtual cystoscopy system, which extracts the bladder wall from T1-weighted MR images where the wall is enhanced while the urine and surrounding fat tissues are suppressed by a fully non-invasive imaging procedure. The system analyzes the extracted wall and detects abnormal features automatically. Test results are encouraging by FROC ...

In the past three decades, the use of smart methods in medical diagnostic systems has attractedthe attention of many researchers. However, no smart activity has been provided in the eld ofmedical image processing for diagnosis of bladder cancer through cystoscopy images despite the highprevalence in the world. In this paper, two well-known convolutional neural networks (CNNs) ...

BACKGROUND Patients undergoing both rigid and flexible cystoscopic evaluation suffer from a great deal of pain and discomfort. In this study, we aimed to investigate the effect of lidocaine gel anestesia on patient comfort on diagnostic rigid cystoscopy. MATERIAL AND METHODS 11 mL of lubricant gel applied to each patient via the external meatus in 10 s. Patients were randomized into three gro...

c Abstract: Background: Bladder diverticulae are mucosal outpunching and majority are acquired and secondary to either benign prostatic hypertrophy or the upper motor type of neurogenic bladder. Aim & Objectives: This study was undertaken to increase knowledge and understanding the presumed role of Benign Prostatic Hyperplasia (BPH) in the development of bladder diverticulae and to compare cyst...

OBJECTIVE To assess the clinical performance of the NMP22 BladderChek test, which is a qualitative test, and to compare it with voided urine cytology for the detection of recurrent bladder cancer. We also evaluated whether cystoscopy can be omitted from the surveillance protocol by combining the two tests. METHODS A total of 131 patients with a history of superficial transitional cell carcino...

BACKGROUND Neostigmine is cholinomimetic and is used for postoperative analgesia. Its urodynamics effects on voiding function have not been elucidated. MATERIALS AND METHODS Adult patients without bothersome voiding symptoms planned for rigid cystoscopy under local anesthesia were enrolled. They underwent multichannel urodynamics (filling cystometry and pressure-flow study) before and 30 min ...

Background: Cystoscopy using white light is a standard procedure for diagnosing bladder cancer; however, white light can result in missed lesions that are present, but not visible, such as in cases of carcinoma in situ (CIS). In this case report, we describe observing the nuclei of urothelial carcinoma cells in situ that were not visible with cystoscopy under white light using probe-based confo...

Urothelial bladder cancer is the fourth most prevalent male malignancy in the United States and also one of the ten most lethal. Superficial or non-muscle-invasive bladder cancer has a high rate of recurrence and can progress to muscle invasive disease. Conventional surveillance requires regular cystoscopy and is used often with urinary cytology. Unfortunately, the cystoscopy procedure is invas...
