Ketamine-induced uropathy: A narrative systemic review of surgical outcomes of reconstructive surgery.

Aims: Refractory ketamine-induced uropathy (KU) (RKU) has devastating effects on the lower urinary tract leading to ureteral obstruction and even renal failure. The only effective treatment for RKU is major surgical reconstruction or urinary diversion. Nevertheless, there is a paucity of awareness about this destructive condition; the aim of this study is to conduct a narrative systemic review of all surgical outcomes of RKU.

The role of the bladder diary in phenotyping men with LUTS.

Aims: The aim of this study was to compare the clinical characteristics of men with lower urinary tract symptoms (LUTS) grouped by 24-h urine output determined from a bladder voiding diary.

Methods: An online database was queried to identify men who completed a 24-hour bladder diary (24HBD), and the Lower Urinary Tract Symptom Score (LUTSS) questionnaire from 2015 to 2019 using a mobile app. Data from the bladder diary and questionnaire were contemporaneously matched within a 2-week period.

Polyuria in patients with lower urinary tract symptoms: Prevalence and etiology.

Introduction: Patients with lower urinary tract symptoms (LUTS) can be subcategorized into polyuria, normal or oliguria groups. Polyuria may be caused by pathologies including diabetes mellitus (DM), chronic kidney disease (CKD), diabetes insipidus (DI), or primary polydipsia (PPD). While fluid restriction is appropriate for some, doing so in all may result in serious complications.

Relationship between maximum voided volume obtained by bladder diary compared to contemporaneous uroflowmetry in men and women.

Introduction: The 24-hour bladder diary is considered to be the gold standard for evaluating maximum voided volume (MVV). However, we observed that patients often have a greater MVV during office uroflowmetry than that seen in the bladder diary. The purpose of this study is to compare these two non-invasive methods by which MVV can be determined - at the time of uroflowmetry (Q-MVV), or by 24hour bladder diary (BD-MVV).

Surgery for Stress Urinary Incontinence: Autologous Fascial Sling.

This article describes the operative technique of autologous fascial pubovaginal sling (AFPVS) surgery, examines the senior author's outcomes with AFPVS, compares these outcomes with those of other large studies and meta-analyses, and compares the safety and efficacy of AFPVS with those of the synthetic midurethral sling (SMUS). Recently, the SMUS has become the treatment of choice for most surgeons. The efficacy of the SMUS remains unchallenged and comparable with that of AFPVS, but SMUS are associated with more severe complications.

Natural History of Low-stage Urethral Strictures.

Objective: To determine the natural history and rate of progression of incidental wide-caliber, anterior urethral strictures (USs) in men using a validated stricture staging system.

Subjects And Methods: Men with incidental findings of anterior US on cystoscopy performed for urologic conditions other than US were retrospectively reviewed from 2001 through 2016. Diagnosis of US on cystoscopy was made according to a validated staging system: stage 0 = no stricture; stage 1 = wide-caliber stricture; stage 2 = requires gentle dilation with a flexible cystoscope; stage 3 = impassable stricture with a visible lumen; and stage 4 = no visible lumen.

Urogynecological conditions associated with overactive bladder symptoms in women.

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-approved study included women referred to a tertiary centre with lower urinary tract symptoms (LUTS).

Surgical treatment of detrusor underactivity: a short term proof of concept study.

Objectives: To compare the surgical outcomes of men with bladder outlet obstruction (BOO) due to benign prostatic obstruction (BPO) to those with detrusor underactivity (DU) or acontractile detrusor (DA).

Materials And Methods: This retrospective, IRB approved study included men who underwent BPO surgery for refractory LUTS or urinary retention. Patients were grouped based on videourodynamic (VUDS) findings: 1) men with BOO, 2) men with DU and 3) men with DA.

Long-term Impact of Mode of Delivery on Stress Urinary Incontinence and Urgency Urinary Incontinence: A Systematic Review and Meta-analysis.

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.

Safety considerations for synthetic sling surgery.

Implantation of a synthetic midurethral sling (SMUS) is the most commonly performed anti-incontinence operation in women worldwide. The effectiveness of the SMUS is comparable to that of the historical gold standards--autologous fascial slings and the Burch colposuspension. Much controversy, however, has evolved regarding the safety of this type of sling.

A New Staging System for Anterior Urethral Strictures.

Introduction: Currently there is no widely accepted staging system for anterior urethral strictures. We developed and evaluated the reliability of an easy to use classification system for anterior urethral strictures in men.

Methods: We devised a staging system based on cystoscopic findings of no stricture (stage 0), wide caliber stricture (stage 1), stricture requires gentle dilation with a 16Fr flexible cystoscope (stage 2), stricture cannot be dilated (stage 3) and no visible lumen (stage 4).

Management of urinary fistulas due to midurethral sling surgery.

Purpose: We report our experience with the diagnosis and treatment of women with urinary fistula after mid urethral sling surgery.

Materials And Methods: We retrospectively reviewed the records of patients with urinary fistula secondary to mid urethral sling surgery. Electronic medical records and billing records were searched.

Outcomes of reduction cystoplasty in men with impaired detrusor contractility.

Objective: To report surgical outcomes in patients with impaired detrusor contractility (IDC) treated with reduction cystoplasty (RC).

Methods: This was a retrospective study of consecutive patients with IDC who underwent RC. IDC was defined as a bladder contractility index of <100 and/or a detrusor contraction of insufficient duration resulting in a postvoid residual volume (PVR) >600 mL.

Pad count is a poor measure of the severity of urinary incontinence.

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 told to use the usual pads, change them as usual and place each in a separate plastic bag the day before the scheduled appointment.
