Filter by:Women with symptoms of voiding dysfunction may be associated with detrusor underactivity (DU) or bladder outlet obstruction (BOO). The treatment strategies are different between DU and BOO. In general, urodynamic/videourodynamic studies are important for differential diagnosis. However, urodynamic/videourodynamic studies are invasive. The investigators are interested in whether there were specific symptoms or measurements that can be used for initial differential diagnosis between DU and BOO. Thus, the aim of this study was to elucidate the prevalence of DU and BOO in each age group and elucidate the clinical and urodynamic differences between the DU, BOO and non-DU/BOO groups.
Our study included 60 patients with idiopathic OAB and treated with solifenacin 5mg twice daily for one month. After improvement of their condition, we divided the responders into 2 groups, group I stopped the drug suddenly, while group II underwent gradual weaning of the drug.
Trial of void (TOV) is a diagnostic test performed on all women who undergo prolapse repair or incontinence surgery, due to the importance of diagnosing postoperative urinary retention (POUR). Incidence of POUR may be as high as 62% in some studies. Timely and accurate diagnosis is important to avoid complications such as urinary tract infection, bladder overdistension, and permanent bladder injury. Despite the frequent use of TOV, there is no gold standard for the test, and it likely has poor specificity, leading to discharge of more patients with catheter than required. This prospective cohort study will seek to establish evidence-based optimal parameters for spontaneous trial of void, a TOV modality that has merit for further evaluation given lower theoretical risk of urinary tract infection.
Benign Prostatic Hyperplasia (BPH) affects the storage and voiding phases of the micturition cycle. Lower urinary tract symptoms (LUTS) refers to storage symptoms such as urinary frequency, urgency, urge urinary incontinence and nocturia. Surgical options for bladder outlet obstruction (BOO), including prostate ablation and transurethral resection, are currently offered for symptomatic improvement. However, 30% of patients report persistent LUTS after BOO procedures. Neuroplasticity induced by BPH and BOO can be contributory of persistent LUTS in these men, having different brain activation patterns during the micturition cycle. The investigators proposed unique multimodal functional Magnetic Resonance Imaging (fMRI) study that will identify for the first time, structural and functional brain contributions to LUTS in men with BPH and BOO at baseline and following BOO procedures. The investigators hypothesize that men with symptomatic BPH who have persistent LUTS following BOO procedures have a distinct brain activation pattern in Regions of Interest (RoI) that regulate the micturition cycle.
1. Title: Effect of Transcutaneous Acupoint Electrical Stimulation on postoperative spontaneous voiding for Laparoscopic Cholecystectomy patients：A Randomized Clinical Trial 2. Research center: Multicenter 3. Design of the research: A randomized, double-blind and parallel controlled study 4. Object of the research: Patients （40≤age<75 years）planing to elective laparoscopic cholecystectomy under general anesthesia without preoperative placement of catheter. 5. Sample size of the research: A total of 1,200 patients,600 cases in each group 6. Interventions: The acupuncture points for Transcutaneous Acupoint Electrical Stimulation(TAES) are Zhongji ( CV3),Guanyuan ( CV4),Sanyinjiao ( SP6) and Ciliao ( BL32) points . In treatment group patients are treated with low-frequency pulse electroacupuncture stimulation apparatus (HANS G6805-2, Huayi Co, Shanghai, China) at bilateral of SP6 and BL 32 points during the operation,and treated with a similar method at CV6 and CV4 acupoints for 45 minutes in postanesthesia Care Unit. Each devic is connected and maintained after "Deqi". Participants in the control group received nonacupoints (located 1 inch beside acupoints) and avoided manual stimulation and no "Deqi" without actual current output. 7. Aim of the research: Evaluate the effect of TAES on the postoperative spontaneous voiding in patients for Laparoscopic Cholecystectomy (LC ). 8. Outcome：Primary outcomes: The time of the first spontaneous voiding after surgery . Secondary outcomes: symptoms of postoperative voiding, the incidence of Postoperative dysuria,postoperative catheterization rate, catheterization time, incidence of related complications,as well as the effects on postoperative NRS pain and sleep quality scores etc. 9. The estimated duration of the study：2 years.
Urodynamic testing can be associated with mild discomfort, particularly at the time of insertion, repositioning, and removal of the bladder catheter (a tube inserted into the bladder via the urethra). Few studies have investigated ways to improve patient comfort during this procedure. In this study, the investigators want to see if applying external lidocaine (a numbing gel) prior to the procedure can help to minimize patient discomfort.
The purpose of this study is to evaluate the patient satisfaction with voiding assessment remotely after removal of Foley catheter at home by the patient or her caregiver compared to removal at the office by a healthcare provider in patients who have been diagnosed to have voiding difficulty after pelvic reconstructive surgery.
The intent of this mixed methods study for transgender women after gender confirmation surgery is to characterize and subsequently create a validated screening questionnaire for postoperative urologic and pelvic floor symptoms. For individuals who seek gender-confirming treatment, about 13% undergo genital surgery for cosmetic purposes with or without gonadectomy, and this number is increasing. Patient satisfaction following surgery is high, particularly regarding sexual and cosmetic outcomes; however, unexpected negative functional outcomes such as bowel and bladder dysfunction and pelvic organ prolapse impact overall patient satisfaction. The available information suggests that 16-33% of patients experience incontinence postoperatively, with stress predominance, 32-47% experience abnormal voiding, and 24-66% experience overactive bladder symptoms. Outside of the typically assessed voiding symptoms, unique complaints of MTF postoperative patients include obstructive voiding symptoms due to urethral stenosis, persistent perimeatal erectile tissue, prostatic hypertrophy, and irritation from neovaginal tissue. Additionally, may of these patients develop symptomatic neovaginal prolapse, requiring re-suspension. We suggest that further clarification regarding MTF postoperative urologic and pelvic floor complaints can be achieved via a mixed methods approach. By using focus group interviews to create specific evaluative questions for this unique population, we can then prospectively assess patients undergoing surgery via a national multicenter sampling strategy. The goal of the study is to better understand the unique symptoms these women experience and create a validated, reliable screening questionnaire to monitor patients after surgery.
Acute urinary retention is a complication of hysterectomies that can result in bladder over-distension and long term bladder dysfunction. The incidence of acute urinary retention after total laparoscopic hysterectomy (TLH) has been reported to be anywhere between 4% and 34%. Studies have varied in the method of post-operative bladder challenge and the modality of hysterectomy included. Moreover, most of the published studies are retrospective chart reviews or prospective observational studies, with a lack of randomized controlled trials. Risk factors for urinary retention include type of anesthesia used, how the hysterectomy is performed, use of post-operative narcotics, pre-operative urinary retention, and possibly aggressive bladder dissection. With the increased trend towards same-day discharge following TLH, urinary retention may cause unnecessary patient distress and a worsened post-operative course. Standardization of post-hysterectomy bladder challenge and identification of risk factors for urinary retention may aid in preventing urinary retention or acute bladder dysfunction. The primary objective is to compare the rate of void trial failure after TLH with the backfill technique versus the autofill technique.
