The effect of pelvic floor muscle training in women with functional bladder outlet obstruction.

INTRODUCTION AND HYPOTHESIS: Female voiding dysfunction is often due to bladder outlet obstruction (BOO). We investigated pelvic floor muscle training (PFMT) effectiveness in women with functional BOO. METHODS: This is a prospective study recruiting 63 women functionally obstructed, over 18yo, maximum flow rate (Qmax) less than 12 ml/sec, naïve of voiding treatment. Exclusion criteria were anatomical BOO, neurological condition, pelvic intervention, psychiatric or anticholinergic medication, diabetes mellitus and affected upper urinary tract. At baseline, women underwent uroflow, post void residual (PVR) measurement, cystoscopy, cystogram and urodynamic study (UDS) with pelvic electromyography (EMG). Blaivas-Groutz nomogram has been used to define obstruction. After diagnosis, patients underwent six-month PFMT. Re-evaluation was offered four weeks after end of treatment. Data were analyzed with SPSSv22.0. RESULTS: 63 women were recruited and 48 finally included. At baseline, 20 reported 3 urinary tract infections (UTIs) during last year, and 12 had one episode of urine retention. Median Qmax was 7.5 ml/sec and median PVR 110 ml. 40 women were obstructed. 16 (40%) had mild, 16 (40%) moderate and 8 (20%) severe obstruction. All subjects had an overactive pelvic floor on EMG. Obstructed women were re-evaluated. Median Qmax was 8.5 ml/sec, close to baseline (p = 0.16). Median PVR was 65 ml, reduced to baseline (p = 0.02). 33 (82.5%) remained obstructed, 22 (66.67%) with mild, 8 (24.24%) moderate and 3 (9.09%) severe obstruction. 7 (17.5%) were non-obstructed. 4 patients reported one UTI episode with no cases of retention. CONCLUSIONS: A 6 month PFMT reduced UTIs and PVR in women with functional BOO. Additionally, most patients had a de-escalation to milder obstruction.

Detrusor Overactivity May Be a Prognostic Factor for Better Response to Combination Therapy Over Monotherapy in Male Patients With Benign Prostatic Enlargement and Storage Lower Urinary Tract Symptoms / 대한배뇨장애요실금학회지

Purpose@#Several trials have shown that in men with overactive bladder (OAB) and benign prostate enlargement (BPE), the combination of an α-blocker with an anticholinergic is superior to α-blocker monotherapy. The purpose of this study is to explore whether urodynamic detrusor overactivity (DO) affects clinical outcomes in men with BPE and OAB. @*Methods@#This is a post hoc analysis of a prospective, randomized trial, designed to evaluate the changes of morphometric parameters of the prostate following monotherapy or combination therapy in men with BPE-OAB. The initial study recruited men aged ≥50 years, with BPE and predominantly storage lower urinary tract symptoms (LUTS). Patients were randomized to receive tamsulosin monotherapy or a combination of tamsulosin and solifenacin for 26 weeks. All participants completed a 3-day bladder diary and the International Prostate Symptom Score (IPSS), and then underwent pressure-flow and ultrasonographic studies. Data were stratified and analysed based on the urodynamic observation of DO at baseline (DO vs. non-DO). The primary endpoint was the mean change in urgency episodes from baseline. Secondary outcomes were the changes in nocturia, total IPSS, and urodynamic parameters. @*Results@#Sixty-nine men were initially randomized, but only 60 men were included in this analysis. Urgency episodes significantly improved in men with DO who received combination therapy compared to the DO monotherapy subgroup (P=0.04) or to the non-DO combination treatment subgroup (P=0.038). Nocturia also improved in the DO combination treatment subgroup as compared to the non-DO combination subgroup (P=0.037). The 24-hour frequency and total IPSS significantly improved from baseline without significant differences among the subgroups. @*Conclusions@#The present study suggests that baseline DO could be a prognostic factor for a better response to combination therapy over monotherapy in men with BPE and storage LUTS.

Comparison of TVT, TVT-O/TOT and mini slings for the treatment of female stress urinary incontinence: 30 months follow up in 531 patients.

INTRODUCTION: Although mid-urethral slings (MUS), have been extensively used for the treatment of female stress urinary incontinence (SUI), no published data exists for the efficiency and the complications of these methods in large patient series. METHODS: This is a retrospective analysis on patients who underwent MUS surgery since 1999. 531 patients were studied and the results of preoperative assessment, perioperative, early postoperatively and each follow up were registered. Patients were classified in three groups according to the MUS used. Efficacy of each method was evaluated in terms of early postoperative course, late complications and patient's symptoms improvement based questioners, pad test, uroflowmetry, filling cystometry and ultrasonography. Evaluation took place at 7th and 30th postoperative day, 3rd and 12th month and then annually. Each patient was characterized as cured, improved or failed. RESULTS: Trans Obturator (TO) group prevailed in efficiency with no significant differences between trans obturator route with inside-out (TVT-O) and outside-in (TOT). Success rate at 30th month evaluation, was higher in the TO group than in Tension-free Vaginal Tape (TVT) or Single-Incision Mini Slings (SIMS) group (93.4% vs 89.5%, 93.4% vs. 91.7%). None TVT patient required reoperation for remaining/reoccurring SUI, while 1.04% of TO group and 5.48% of SIMS group did. Patients of TVT group underwent reoperation for tape related complications in 2.25%, while 2.07% of TO group and none of SIMS group did. The potential limitation of the study is its retrospective character. CONCLUSIONS: Even though TO tapes and SIMS seem more efficient than TVT, they carry a risk of SUI re-occurrence that must be weighted towards the risk of potential complications after TVT.
