Objective: To investigate the urodynamic study (UDS) patterns, obstruction status, continence status, and their correlations among neurologically intact women with lower urinary tract symptoms (LUTS) through an epidemiological and logistic regression analyses.
Methods: We retrospectively analyzed the UDS data of 3265 neurologically intact women with LUTS (2002-2014). Five UDS patterns were identified: normo-active detrusor/sphincter (NA, or DSI, detrusor/sphincter intact), idiopathic detrusor overactivity (IDO), idiopathic sphincter overactivity (ISO), IDO + ISO, and detrusor underactivity (DUA).
Article Synopsis
- This study focuses on the construction of a neourethra for female-to-male transsexual patients undergoing phalloplasty, specifically using vaginal mucosal grafts.
- A review of 22 FTM patients who underwent this procedure showed positive outcomes, with most patients able to void while standing and a relatively low incidence of complications like urethral fistulas and strictures.
- The research indicates that vaginal mucosa is a suitable and effective material for reconstructing the urethra due to its histological similarities to urethral epithelium and its successful integration in the body.
Objective: To develop a urodynamic study (UDS) pattern system for aged male patients who complained of non-neurogenic lower urinary tract symptoms (LUTS) to create a reference guideline for their diagnosis and treatment by a retrospective analysis.
Methods: A retrospective analysis of UDS data was carried out in 1984 male patients neurologically intact with symptoms suggestive of bladder outlet obstruction (BOO) aged older than 45 years (2002-2013). On the basis of their UDS characteristic findings, the patients were classified into 1 of 7 subgroups: equivocal or mild BOO with sphincter synergia with or without idiopathic detrusor overactivity (pattern A); equivocal or mild BOO with idiopathic sphincter overactivity (B); classic BOO with sphincter synergia (C) or overactivity (D); BOO with only detrusor low compliance (E); BOO with both detrusor underactivity and low compliance (F); and equivocal BOO with detrusor underactivity (G).
Introduction And Hypothesis: The aim of the study was to assess the efficacy of low-frequency electrotherapy (LFE) for female patients with early-stage detrusor underactivity (DUA) due to neuromuscular deficiency.
Methods: A total of 102 female patients were divided randomly into four groups: LFE-NC (normal compliance), LFE-LC (low compliance), CON (control)-NC and CON-LC. Patients in the LFE-NC and LFE-LC groups received LFE, and those in the CON-NC and CON-LC groups received conservative treatment.
Objectives: To determine the prevalence of dysfunctional voiding (DV) in female stress urinary incontinence (SUI) and its modification after tension-free vaginal tape (TVT) procedure.
Methods: Three hundred and sixty women with SUI were enrolled and underwent urodynamics from 2002 to 2008. DV was determined when non-neurogenic detrusor-sphincter dyssynergia occurred during voluntary voiding.
Introduction: Inflammatory eosinophilic pseudotumor of the bladder is a rare inflammatory bladder disease. The etiology and pathophysiology of this condition are still unclear. Few case reports have described inflammatory eosinophilic pseudotumor of the bladder in adults or children.

Patients And Methods: We conducted a randomized double-blind placebo-controlled crossover trial in 60 women with DV and LUTS between January 2003 and January 2006; patients were randomly assigned either baclofen 10 mg three times daily, then matching placebo for 4 weeks, or matching placebo then baclofen 10 mg three times daily for 4 weeks, separated by a 2-week washout period. Voiding diaries and multichannel urodynamics (at baseline, 4 and 10 weeks) were used to record the changes of voids/24 h and urodynamic variables.
