Aims The aim of this study is to report the relationship between bladder compliance and nocturia in men presenting with a variety of lower urinary tract symptoms, and to clarify the level at which bladder compliance becomes an important contributor to nocturia. Methods We report the results of a retrospective analysis of 104 men who presented to a...
Chapter
Partial cystectomy is an option when considering bladder preservation in the management of a solitary bladder tumor and may be performed in conjunction with pelvic lymphadenectomy. Multifocal disease is a contraindication to partial cystectomy. Bladder diverticulectomy can be performed for oncological causes or in the setting of benign disease. The...

Background: Single port (SP) robotic assisted laparoscopic surgery was approved by the FDA for urologic surgery and clinically available in 2018. This new robotic system enables a camera and 3 separate instruments, with fully wristed motions, to be placed through a single 25 mm port. This system was designed to perform complex surgery in narrow de...
Article
Adult renal rhabdomyosarcoma (RMS) is a rare and aggressive entity with a paucity of data and reports in the literature. As a result, treatment guidelines for this malignancy are not well-established. Herein, we present the diagnosis, management and clinical course of a 39-year-old patient diagnosed with primary renal embryonal RMS (ERMS) following...
Chapter
The surgical approach to the adrenal gland was historically described via an open technique. In recent years, laparoscopic and robot-assisted approaches have become the preferred methods for removal of the adrenal gland when affected by a variety of pathologic disorders. Numerous reports and comparative studies have demonstrated minimally invasive...
Article
Purpose: Nocturia (waking from sleep at night to void) is a common cause of sleep disruption and associated with increased comorbidity and impaired quality of life. However, its impact on mortality remains unclear. We performed a systematic review and meta-analysis to evaluate the association of nocturia with mortality, both as a prognostic and ca...
Article
Purpose: Although nocturia is associated with various comorbidities, its impact on falls and fractures remains unclear. We performed a systematic review and meta-analysis to evaluate the association between nocturia with falls and fractures, both as a prognostic and causal risk factor. Materials and methods: We searched PubMed, Scopus and CINAHL...
Article
Introduction: Overactive bladder symptoms (OAB) affect 9-43% of women and are associated with underlying disorders, including pelvic organ prolapse (POP) and stress urinary incontinence (SUI). The aim of this study is to identify urogynecological conditions associated with OAB symptoms. Methods: This prospective, institutional review board-appro...
Article
Full-text available
Context: Stress urinary incontinence (SUI) and urgency urinary incontinence (UUI) are associated with physical and psychological morbidity, and large societal costs. The long-term effects of delivery modes on each kind of incontinence remain uncertain. Objective: To investigate the long-term impact of delivery mode on SUI and UUI. Evidence acqu...
Article
Context: Although vital for decision-making about management, the natural history of nocturia remains uncertain. A systematic review would clarify the issue, but because natural history reviews are uncommon it would require methodological innovations. Objective: To estimate the incidence and remission of nocturia, and refine methods for meta-ana...

Operative management of prostate cancer in a patient who has undergone previous open suprapubic simple prostatectomy poses a unique surgical challenge. Herein, we describe a case of intermediate risk prostate cancer in a man who had undergone simple prostatectomy ten years prior to presentation. The patient was found to have Gleason 7 prostate canc...
Article
Prostate cancer is the most common cancer in men. Men are diagnosed at early stages of prostate cancer with the use of prostate specific antigen. Surgical removal of the prostate is the standard treatment in localized prostate cancer. Complications after surgical procedures are inevitable. Although robotic prostatectomy has resulted in decreased co...
Article
Introduction: To develop and validate a lower urinary tract symptom score (LUTSS) as a measure of lower urinary tract symptom (LUTS) severity and a treatment outcome tool in adults. Materials and methods: An expert panel was convened to develop the LUTSS questionnaire. Content validity was achieved by obtaining subject and expert feedback from two...
Article
Objective: Nocturia may be characterized by indices derived from the frequency-volume chart (FVC). The objective of this study was to determine how these parameters relate to the severity of nocturia in men with and without lower urinary tract symptoms (LUTS). Materials and methods: A retrospective analysis of FVCs was performed in two cohorts o...

Objective: The aim of this study was to explore the relationship between voided volume (VV) and urge to void among patients with lower urinary tract symptoms. Material and methods: Consecutive adult patients (aged 23-90 years) were enrolled, and completed a 24 h bladder diary and the Urgency Perception Scale (UPS). Patients were categorized as u...
Article
Purpose: We analyzed the correlation between pad use, as determined by objective pad count, and the severity of urinary incontinence, as measured by pad weight. Materials and methods: We performed a retrospective study of consecutive incontinent patients who wore pads on a daily basis and were instructed to complete a 24-hour pad test. They were...
Article
Purpose: We report our experience with the diagnosis and treatment of refractory synthetic sling complications in women. Materials and methods: This is a retrospective study of consecutive women with failed treatments for mesh sling complications. Before and after surgery the patients completed validated questionnaires and voiding diaries, and u...
Chapter
Nocturia is a part of life for most older persons, especially men, nearly 90% of whom experience at least one episode of nighttime voiding [1]. It is often cited as one of the most bothersome of lower urinary tract symptoms (LUTS) [2, 3]. Unlike the other common LUTS, nocturia can cause significant morbidity and even mortality for elderly persons.
Chapter
The relationship between overactive bladder (OAB) and nocturia is not well understood. Research has been hampered because of difficulties presented by the definitions of both conditions as well as the lack of methods for discerning the difference between voiding during sleep hours because of awakening for some other reason and voiding after being a...
Article
To validate the Spanish translation of the Overactive Bladder Symptom Score (OABSS) questionnaire. The OABSS was translated into Spanish (OABSS-S) and back translated. The OABSS-S was self-administered to subjects, following internal IRB and ISPOR Good Practices guidelines. Spanish speaking patients >18 years of age were recruited from primary care...
Article
Bladder diverticula can be congenital or acquired. In adults, they are typically associated with bladder outlet obstruction but may also have iatrogenic causes; they are occasionally associated with bladder cancer. Although they are common in men with bladder obstruction, most diverticula are small and require no treatment other than that required...
Article

Study inclusion criteria were 1) clinical diagnosis of stricture, 2) stricture seen on cystoscopy, 3) urethral obstruction on videourodynamics according to the Blaivas-Gr...
