The aim of this study is to investigate the feasibility and efficacy of a novel biomimetic poly-l-lactide (PLLA) nanofiber membrane in repairing anterior urethral strictures from both preclinic and clinic. Biomimetic PLLA membrane was fabricated layer by layer according to the structure of human extracellular matrix. Microstructure, tensile strength, and suture retention strength were fully assessed.

Objectives: This study aimed to investigate the effects of ketanserin on micturition mediated via the 5-HT receptor in the motoneuron nucleus of the Lumbosacral cord, as reflected in high frequency oscillations (HFOs) of intravesical pressure and the external urethral sphincter electromyogram (EUS-EMG) in anesthetized male rats. METHODS:: Male Sprague-Dawley rats were used. Cystometry and EUS-EMG were performed in all rats under urethane anesthesia to examine the variations after successive intrathecal (i.
View Article and Find Full Text PDFObjectives: To examine the effect of intrathecal (i.t.) serotonin (5-hydroxytryptamine) 5-HT agonist administration on voiding function in the urethane-anesthetised rat, and the change in 5-HT receptor (5-HT R) expression in the lumbosacral cord Onuf's nucleus after spinal cord injury (SCI).

In this study, we aimed to identify the most efficient sensory and motor spinal nerve roots involved in the micturition reflex. Unilateral L5-S2 dorsal and ventral roots were electrically stimulated, and bladder reflex contractions were recorded under isovolumetric conditions.

Methods: We searched the PubMed, EMBASE, and EBSCO databases for articles published until June 2016. Studies that reported the efficacy and safety of repeat BTX-A injections for adult patients with NDO were eligible.
Objectives: To investigate whether the voiding dysfunction caused by spinal cord injury (SCI) in rats can be improved by i.v. administration of the serotonin (5-HT) receptor agonist 2,5-dimethoxy-4-iodophenyl-2-aminopropanehydrochloride (DOI), and to discuss whether the mechanism can be ascribed to 5-HT and 5-HT receptor upregulation in lumbosacral cord motoneurons.

Methods: A retrospective study of 2001 subjects derived from the outpatient clinic at our institution (Shanghai Jiao Tong University Affiliated Sixth People's Hospital in Shanghai) who were diagnosed with benign prostatic hyperplasia (BPH) and prostatitis was reviewed. All subjects were evaluated by the International Prostatic Symptom Score and transrectal ultrasound of the prostate.
Objective: The purpose of this study was to evaluate the long-term efficacy and safety of laser vaporesection using the RevoLix(™) 70 W 2 μm continuous wave (CW) laser in the treatment of benign prostatic hyperplasia (BPH).
Background Data: From January 2008 to December 2008, 162 patients with BPH underwent vaporesection using 2 μm CW laser.
Materials And Methods: The International Prostate Symptom Score (IPSS), quality of life (QoL), urinary flow rate (Qmax), post-voiding residual urine volume (PVR), and postoperative complications were observed at baseline and were followed at 3-, 6-, and 12-month intervals (range: 3-60 months).
Background And Objective: Until now, various laser types have been used in the treatment of bladder cancer. The purpose of this study is to evaluate the feasibility and effectiveness of 2 μm continuous-wave (CW) thulium laser in treating primary non-muscle-invasive bladder cancer (NMIBC).
Methods: A comparative (randomized prospective) interventional study was conducted in our center.
Objectives: To examine the effects of the serotonin (5-HT)2A/2C receptor agonist (2,5-dimethoxy-4-idophenyl)-2-aminopropane hydrochloride (DOI) on micturition in rats with diabetes mellitus (DM).
Methods: Female Sprague-Dawley rats (n = 16) were divided into two groups: rats with Type 1 DM and age-matched control rats. DM was induced by i.
Aims: To better understand the effects of the selective 5-HT7 receptor agonist 4-[2-(Methylthio)phenyl]-N-(1,2,3,4-tetrahydro-1-naphthalenyl)-1-piperazinehexanamide hydrochloride (LP44) on micturition in spinal cord injury (SCI) rats.
Methods: Female Sprague-Dawley rats weighing 200-275 g were used. SCI was produced in 8 of the 16 rats by transection at the T10 level; cystometric study occurred 8-12 weeks post-transection.
Objective: To evaluate the safety and efficacy of the RevoLix 70W 2 micron continuous wave laser vaporesection in the treatment of high-risk patients with benign prostatic hyperplasia (BPH).
Background Data: Forty-six high-risk patients (mean age, 82.6 y old) with BPH underwent 2-μm continuous wave laser vaporesection.
Background: Urethroplasty of complex urethral stricture is a difficult procedure, and there is no widely accepted standard approach described in the published literature. We evaluated the efficacy and safety of urethroplasty using lingual mucosa grafts (LMGs) for the repair of urethral strictures.
Methods: Between August 2006 and April 2009, 92 cases of urethral strictures (length ranging from 2.
Objective: To evaluate the efficacy and safety of using oral mucosal grafts for urethroplasty in the treatment of complex segmented urethral strictures.
Methods: Between January 2002 and January 2008, 25 cases of long or multi-segmented urethral strictures (10-18 cm, mean 11.72) were treated using combined two oral mucosal graft urethroplasty.
Objectives: To develop and report our initial experience with a novel antirefluxing technique for segmental ileal ureteric replacement for the treatment of long ureteric strictures.
Patients And Methods: Between January 2000 and January 2007, 12 cases of ureteric strictures (nine bilateral and three unilateral) were treated using a novel surgical technique in which the ureter was replaced with a segment of ileum using an end-to-side anastomosis. An antireflux valve was constructed by fixing the distal part of upper ureter (4 cm) between the psoas muscle and ileal segment (the ileo-psoas tunnel technique).
