RESUMEN

INTRODUCTION AND HYPOTHESIS: Our aim was to evaluate the clinical outcome of continent women with high-risk predictors for de novo stress urinary incontinence (SUI) offered prophylactic midurethral sling (MUS) insertion during vaginal pelvic reconstructive surgery (PRS) for advanced pelvic organ prolapse (POP). MATERIALS AND METHODS: This was a prospective cohort study in patients with POP stage ≥ 3 and maximum urethral closure pressure (MUCP) <60 cmH2O and functional urethral length (FUL) <2 cm. Patients were divided into PRS and PRS + MUS groups. Surgery commenced with vaginal hysterectomy, application of Uphold® and insertion of MUS to the PRS + MUS group. Main outcome measures were incidence of de novo urodynamic stress incontinence (USI), lower urinary tract symptoms (LUTS), quality of life (QoL), and topographic and anatomical relationship of implanted mesh. RESULTS: Based on sample size calculation, 40 patients were recruited-20 in each group. Rate of de novo USI in PRS + MUS was 5% objectively and 10% subjectively, while in the PRS it was 50% objectively and 60% subjectively. No significant difference was noted in patient demographics. Intraoperative blood loss was greater for PRS + MUS but was not statistically significant. No organ injuries, mesh exposure, or infections occurred. Postoperatively, MUCP significantly increased from 43.3 ± 8.9 to 58.5 ± 19.2 cmH2O and FUL from 17.2 ± 1.9 to 20.3 ± 3.1 mm in the PRS + MUS group. Residual urine significantly decreased. No patient had bladder outlet obstruction (BOO). Sonographic assessment showed no difference in mesh mobility with urethral kinking observed in 11 (55%) patients with MUS. CONCLUSION: Based on a validated small sample, prophylactic MUS for continent women at high risk for postoperative USI with advanced POP lowers its incidence to 5%. Continence is achieved in 95%. Concern for complications, LUTS, and QoL did not significantly differ.

RESUMEN

INTRODUCTION AND HYPOTHESIS: To determine the clinical outcomes of adding a tension-releasing suture (TRS) appendage for manipulation of over-tensioned single-incision slings (SIS) as a means to relieve postoperative voiding dysfunction. METHODS: A retrospective observational study conducted from January 2010 to July 2017. The records of patients with urodynamic stress incontinence (USI) without needing concurrent procedures who underwent anti-incontinence surgery using MiniArc, Solyx, and Ajust with voiding dysfunction were collated and analyzed. The primary outcome measure was the recovery of normal post-void residual urine (PVR) after TRS manipulation. The secondary outcome measures were the pain intensity noted during manipulation (quantified by visual analog scale) and the continence rate [assessed by (1) objective cure: 1-h pad test weight < 2 g and absence of USI; (2) subjective cure index score ≤ 1 on question 3 of the UDI-6: "Urine leakage related to physical activity, coughing, or sneezing?"]. RESULTS: There were 73 patients with high post-void residual (PVR) urine. The 42 (9.5%) patients with over-tensioned slings were managed with TRS manipulation while the 31 patients (7%) with high PVR and no sling over-tension were managed with intermittent catheterization. All patients in both groups regained normal PVR. The TRS-manipulated group demonstrated an objective cure rate of 92.9% (39/42) and subjective cure rate of 91% (38/42). Pain experienced during TRS manipulation was significantly higher with the Ajust system (p = 0.018). Three patients had persistence of USI, two with MiniArc and one with Solyx. CONCLUSIONS: The TRS manipulation is a well-tolerated procedure that can effectively relieve voiding dysfunction for over-tensioned SIS without affecting continence cure rates.

RESUMEN

STUDY OBJECTIVE: To evaluate the clinical outcome and identify risk factors for failure of the Solyx (Boston Scientific Corporation, Marlborough, MA) single-incision sling (SIS) in the treatment of urodynamic stress incontinence (USI). DESIGN: A retrospective observational study (Canadian Task Force classification II-2). SETTING: A tertiary referral center. PATIENTS: Patients diagnosed with USI without needing concurrent procedures that underwent continence surgery using the Solyx SIS from February 2015 to May 2017. INTERVENTIONS: Anti-incontinence surgery. MEASUREMENTS AND MAIN RESULTS: The primary outcome of this study was the rate of objective cure defined as the absence of demonstrable leakage of urine on the cough stress test and a 1-hour pad test weight of less than 2g. The secondary outcome was the rate of subjective cure defined as a negative response to Urinary Distress Inventory question 3 (no leakage on coughing, sneezing, or laughing) and the identification of the different risk factors of cure failure. A total of 113 patients were evaluated in the study. Postoperative USI and the 1-hour pad test significantly improved from 24.2 ± 26.9 gm (range, 19.1-29.3) to 2.5 ± 8.7 gm (range, 0.9-4.2); p <0.001 through 1 year. Data analysis showed an objective cure rate of 90% (102/113) and a subjective cure rate of 86% (97/113). USI recurred in 11 patients with no repeat surgery done becausesymptoms were tolerable to the patients. No patient had bladder outlet obstruction. Peak flow rates 23.7 ± 9.1 ml/s (20.0-27.4) and residual urine volume 38.5 ± 25.8 ml (29.8-47.2) were within normal limits with no significant changes. Previous anti-incontinent surgery, previous prolapsed surgery, intrinsic sphincter deficiency, maximum urethral closure pressure <40cm H2O, and neurogenic disease were significant risk factors for sling failure. Subjective assessment on the quality of life significantly improved (p <0.001). CONCLUSION: The Solyx SIS is an effective and safe treatment option for women with USI, showing high objective and subjective cure rates with a low incidence of complications 1 year after treatment. The identified independent risk factors forfailure are related to poor urethral function and previous pelvic reconstructive surgery.

RESUMEN

AIM: The aim of this study was to investigate the contributing factors of persistent detrusor overactivity (DO) in women with advanced pelvic organ prolapse (POP) after transvaginal mesh (TVM) repair. METHODS: We retrospectively evaluated consecutive patients with DO and advanced POP who had undergone TVM in a tertiary hospital between 2010 and 2014. All patients received evaluations, including a structured urogynecological questionnaire, pelvic examination using the POP-Quantification System, scores of the Urogenital Distress Inventory and Incontinence Impact Questionnaire, and urodynamic testing before TVM repair and 6 months after surgery. Patient demographics, lower urinary tract symptoms, including urinary urgency, incontinence and frequency, and urodynamic findings were analyzed between women with and without persistent DO at 12 months after surgery. RESULTS: Of 326 patients with POP who underwent TVM repair, 63 with preoperative DO were included. Urinary urgency was present in 27 (42.9%), and urgency incontinence was present in 26 (41.3%) patients. Nineteen (30.2%) patients had persistent DO after surgery. Patients with persistent DO had lower preoperative maximal flow rate (MFR), higher preoperative detrusor pressure at maximum flow, higher postoperative residual urine volume and higher rates of concomitant sacrospinous ligament suspension compared to those without DO. In the multivariate analysis, preoperative MFR and concomitant sacrospinous ligament suspension were associated with persistent DO. CONCLUSION: Twenty percent of women with advanced POP had DO, and most of these cases resolved after prolapse repair. For women with lower preoperative MFR and concomitant sacrospinous ligament suspension, preoperative counseling should consist of a discussion about persistent DO and relevant urinary symptoms following TVM repair.

RESUMEN

AIMS: The aim of this study was to investigate the efficacy of extracorporeal magnetic stimulation (EMS) for the treatment of bothersome and severe symptoms of stress urinary incontinence (SUI) and overactive bladder syndrome (OAB) in female patients. MATERIAL AND METHODS: A retrospective review was conducted on patients with SUI and OAB who were referred to EMS therapy. Successful treatment for the bothersome symptoms of OAB and SUI was defined as score ≤1 for questions 2 and 3 on the Urodynamic Distress Inventory-6. The objective cure of SUI and OAB was defined as no urinary leakage during the cough stress test and any urgency, urge incontinence and voiding frequency of less than eight times per 24 h based on the 3-day bladder diary, after the 9 weeks of treatment, respectively. RESULTS: Ninety-three patients with SUI or OAB underwent a 9-week course of EMS at 20 min twice weekly. Seventy-two (77%) patients completed EMS treatment. Geographical factor and poor economic status were two main factors for dropout. A total of 94.1% (32 of 34) and 86.8% (33 of 38) of subjects had successful treatment for the bothersome symptoms of OAB and SUI, respectively. In contrast, the cure rate for OAB and SUI was only 61.7% and 42.1%, respectively. There was also a significant improvement in both Urogenital Distress Inventory Short Form (bothersome on lower urinary tract symptoms) and the Incontinence Impact Questionnaire Short Form (quality of life) total score in both groups after EMS. CONCLUSIONS: EMS is a safe and effective alternative method for treating SUI and OAB. Further studies are needed to evaluate the long-term efficacy.

RESUMEN

OBJECTIVE: This study aimed to apply three-dimensional (3D) printing technology to treat women with pelvic organ prolapse (POP) and to evaluate efficacy based on the improvement by quality of life (QOL) questionnaires. METHODS: This was a pilot study at a tertiary urogynecology unit in Taiwan. Between January 2021 and June 6, 2021, participants who opted for self-management using Gellhorn pessaries to treat symptomatic POP were enrolled. For each woman, the original Gellhorn pessary was placed into the vagina to restore the prolapsed tissues and under transvaginal ultrasound guided to evaluate the gap which the Gellhorn pessary cannot cover. Otoform (an impression silicone) was used to make a model and have it hooked onto Gellhorn pessary (template). We collected templates and then applied 3D printing to customize the silicone vaginal pessary. All women completed multiple validated QOL questionnaires at baseline and at 3 and 6 months. RESULTS: Six women completed the study. The QOL questionnaires revealed significant improvements across the board. CONCLUSIONS: Our study demonstrates that a tailor made 3D pessary can be used for women with POP. A customized pessary can be made with the help of transvaginal ultrasound and 3D printing technology.

RESUMEN

INTRODUCTION AND HYPOTHESIS: Synthetic mesh kits recently adopted in pelvic reconstructive surgeries have achieved great surgical efficacy, but the effects of transvaginal synthetic mesh procedures on women's sexual function are still controversial. This study was conducted to demonstrate sexual function in women before and after surgery with transvaginal mesh (TVM) repair for pelvic organ prolapse (POP). METHODS: A total of 93 sexually active women scheduled for correcting POP with synthetic mesh kits were recruited. In addition to urogynecological history, pelvic examination by the Pelvic Organ Prolapse Quantification system, and urodynamic testing, consenting participants were asked to complete the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) to evaluate sexual function before and after surgery. RESULTS: At the 3-month urodynamic studies, among the 25 patients with coexistent urodynamic stress incontinence (USI) who had undergone a concomitant transobturator suburethral tape procedure (TOT), 1 (4 %) had persistent USI; 8 of 68 (11.8 %) patients with a negative pessary test developed postoperative USI. Six-month prolapse recurrence rates following TVM alone and TVM with concomitant TOT were 9 and 12 %, respectively. The total PISQ-12 score after surgery showed worse results in the TVM alone group but not in the TVM with concomitant TOT group. The individual scores of PISQ-12 after surgery demonstrated prolapse-related items improved in both TVM groups; sexual function worsened in dyspareunia and behavior domains. CONCLUSIONS: Our data revealed that transvaginal synthetic mesh procedures for the treatment of POP generated favorable clinical outcomes, but situations might worsen in dyspareunia and behavior domains, thereby invoking a negative emotional reaction during intercourse after surgery.

RESUMEN

INTRODUCTION AND HYPOTHESIS: Midurethral tapes have shown favorable clinical outcomes for treating stress urinary incontinence (SUI), but the effects of outside-in transobturator midurethral sling procedures (TOT) on women's sexual function are unclear. We hypothesized that TOT might improve sexual function in women with SUI and therefore conducted this study to investigate sexual function alteration among women who underwent TOT for urodynamic stress incontinence (USI). METHODS: From November 2009 to October 2010, we recruited 102 women scheduled for correction of USI by TOT procedures in a tertiary hospital. In addition to urogynecologic history, pelvic examination, and urodynamic testing, participants were required to complete three validated questionnaires: Incontinence Impact Questionnaire (IIQ-7), Urogenital Distress Inventory (UDI-6), and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Preoperative and postoperative results of these validated questionnaires were evaluated. RESULTS: Eighty-three patients comprising 57 sexually active and 26 sexually inactive patients participated in the 12-month evaluation. Of the 83 patients undergoing TOT, six (7.2 %) had postoperative SUI 12 months postoperatively. Both UDI-6 and IIQ-7 scores were significantly improved postoperatively. The total PISQ-12 score did not change significantly after surgery. Postoperatively, the individual incontinence-related items of the PISQ-12 improved, but climax with intercourse and negative emotional reactions during intercourse worsened (both with p <0.001). There was a negative correlation between SUI-related items on UDI-6 and those on PISQ-12 preoperatively. CONCLUSIONS: TOT procedures for correcting USI had favorable clinical outcomes and did not alter overall sexual function; however, climax during sexual intercourse and emotional response worsened postoperatively.

RESUMEN

STUDY OBJECTIVES: To estimate the effect of pessary use on symptom improvement and quality of life in women with pelvic organ prolapse, to examine factors that influence patient choice and continued use of a pessary, and to determine reasons associated with discontinuation of pessary use. DESIGN: Retrospective study (Canadian Task Force classification II-3). SETTING: Outpatient urogynecologic clinic of a university hospital. PATIENTS: Seventy-two patients with symptomatic pelvic organ prolapse were evaluated for pessary insertion between March 2006 and August 2008. INTERVENTIONS: Insertion of a Gellhorn pessary. MEASUREMENTS AND MAIN RESULTS: Urinary symptoms and quality of life were assessed using the Urinary Distress Inventory incontinence questionnaire (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7) at baseline and postinsertionally at 2 months and at 1 year. Frequency of choosing pessary use or surgery and rate of continuous use of a pessary was compared between groups. Compared with baseline findings, at 1 year, UDI-6 and IIQ-7 demonstrated significant improvement in frequency of micturition, stress incontinence, voiding function, and bowel evacuation. Substantially more older or menopausal women opted for a pessary rather than surgery, and significantly more sexually active women preferred surgery. Women with diabetes mellitus or occult stress urinary incontinence and those without family support are more likely to discontinue pessary use. CONCLUSIONS: Use of a pessary in treatment of pelvic organ prolapse is associated with good compliance, and results in significant improvement in quality of life and urinary and bowel symptoms. Women with diabetes or occult stress urinary incontinence and those without family support should receive intensive counseling before placement of a pessary.

RESUMEN

BACKGROUND: There are 3 different types of mid-urethral sling, retropubic, transobturator and single incision performed for women with stress urinary incontinence. Prior studies comparing these three surgeries merely focused on the successful rate or efficacy. But nevertheless, what is more clinically important dwells upon investigating postoperative complications as a safety improvement measure. METHODS: A systematic review via PubMed, Ovid, and the Cochrane Database of Systematic Review and studies were applied based on the contents with clearly identified complications. Selected articles were reviewed in scrutiny by 2 individuals to ascertain whether they fulfilled the inclusion criteria: complications measures were clearly defined; data were extracted on study design, perioperative complications, postoperative lower urinary tract symptoms, postoperative pain, dyspareunia, and other specified late complications. RESULTS: A total of 55 studies were included in the systemic review. Perioperative complications encompassed bladder perforation, vaginal injury, hemorrhage, hematoma, urinary tract infection. There were postoperative lower urinary tract symptoms including urine retention and de novo urgency. Furthermore, postoperative pain, tape erosion/ extrusion, further stress urinary incontinence surgery, and rarely, deep vein thrombosis and injury of inferior epigastric vessels were also reported. CONCLUSIONS: Complications of mid-urethral sling are higher than previously thought and it is important to follow up on their long-term outcomes; future research should not neglect to address this issue as a means to improve patient safety.

RESUMEN

OBJECTIVE: We report a case of diffuse large B-cell urethral lymphoma initial presenting with non-healing urethra ulcer. CASE REPORT: A 68-year-old woman presented with a non-healing urethral ulcer accompanied with vulvar pruritus, which failed to medical treatment. Her medical history was unremarkable, lacking fever, weight loss or unexplained fatigue. There were no enlarged lymph nodes or palpable liver or spleen upon physical examination. Pelvic examination revealed an ulcerative lesion arising from the posterior wall of the urethral meatus. Cystourethroscopy showed no bladder involvement. Surgical excision of the urethral ulcer was done and immunohistochemical report showed a diffuse large B-cell lymphoma. Bone marrow needle biopsy and computed tomography were done and the diagnosis of primary diffuse large B-cell urethral lymphoma stage IEA was made. She underwent six cycles of cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab and was free of disease for 51 months. CONCLUSION: This report of urethral lymphoma was presented as a non-healing ulcer initially, which was totally different previous reports, presenting with bleeding, either vaginal or urinary, urinary frequency, dysuria, urine retention and self-perceived mass, suggesting that unhealed ulcer on the perineal area should be promptly evaluated and avoidance of unnecessary delayed therapy for possible curable disease.

RESUMEN

AIM: To explore the potential molecular mechanisms underlying experimental neurogenic bladder dysfunction. METHODS: With the aid of Affymetrix GeneChip Rat Genome U34A arrays, we examined microarray gene expression profiles in bladder wall tissue from female Sprague-Dawley rats within the first 3 weeks following spinal cord injury. Gene transcripts expressed in rat bladder wall tissue at 3 days, 7 days, and 3 weeks following spinal cord injury were compared to normal rat bladder wall tissue. RESULTS: The Mahalanobis distance in hierarchical cluster analysis revealed a 48-gene model, which contained high expressions in rat bladder wall tissue at 3 days, 7 days, and 3 weeks following spinal cord injury. According to gene ontology, plausible molecular alterations in rat bladder wall tissue following spinal cord injury include: (1) the release of nerve growth factor (NGF) and transforming growth factor beta 1 (Tgfb1) (2) the secretion of histamine from mast cells, (3) the occurrence of blood coagulation, (4) the occurrence of N-terminal protein myristoylation, and (5) Axon guidance mediated by Ena/Vasodilator-stimulated phosphoprotein (Ena/VASP) promotes reestablishment of the bladder reflex following spinal cord injury. Such changes, jointly termed "bladder remodeling," can constitute an important long-term consequence of neurogenic bladder dysfunction. CONCLUSION: The success of this innovation has supported the use of microarray-based expression profiling as a commonplace platform for the pathogenesis and therapeutic interventions of experimental neurogenic bladder dysfunction. dysfunction.

RESUMEN

AIMS: The bladder contractile dysfunction resulting from acute ischemia may be attributed to nerve growth factor (NGF) overexpression. This study was conducted to evaluate the acute and mid-term effects of bladder ischemia on the temporal expression of NGF immunoreactivity and mRNA. MATERIALS AND METHODS: Bladder ischemia was induced by ligation of bilateral vesical arteries in female rats. We examined the NGF content of bladder detrusor muscle at 1 day, 1 week and 4 weeks after artery ligation. Immunoreactivity of NGF was studied by immunofluorescent staining and Western blot. The NGF mRNA was analyzed by real-time polymerase chain reaction. RESULTS: The immunofluorescence of NGF at 1 week and 4 weeks was significantly reduced when compared to sham-operated group (P < 0.05). This decreased tendency was also found in Western blot test. An increased expression of NGF mRNA was noted at 1 day, 1 week and 4 weeks, but had no significant change when compared to sham-operated group (P > 0.05). CONCLUSIONS: Our study showed bilateral vesical artery ligation may cause damage of detrusor muscle and there is decreased NGF immunofluorescence and elevated NGF mRNA in bladder suggesting an expression disparity following ischemia.

RESUMEN

INTRODUCTION AND HYPOTHESIS: To explore the potential molecular mechanisms contributing to the pathogenesis of pelvic organ prolapse (POP) with the aid of high-density oligonucleotide microarrays. METHODS: We compared microarray gene expression profiles in pelvic connective tissue from women with POP and nonprolapse controls. The round ligament and uterosacral ligament tissues were removed from each subject at the time of laparoscopic hysterectomy. RNA was then extracted, and all labeled samples were hybridized to ABI Human Genome Survey Microarray version 2.0 (Applied Biosystems, CA, USA). RESULTS: The Mahalanobis distance in hierarchical cluster analysis revealed a model of 33 genes, which contained high expressions of round and uterosacral ligaments from women with POP. According to gene ontology, the expressions of mitochondrial genes encoding ribosomal protein were upregulated. Genes involved in potential interactions with mitochondrial electron transport, nucleosome assembly, cell cycle, and apoptosis were also upregulated. As a result, defective mitochondrial translation caused by ribosomal protein contributes to the potential molecular etiology of POP. Such changes, jointly termed "remodeling of pelvic connective tissue", can constitute an important long-term consequence of POP. CONCLUSIONS: Our results support the use of genome-based expression profiling as a commonplace platform for diagnostic tests of POP.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The aim of this study was to explore potential molecular mechanisms contributing to the pathogenesis of Hunner's ulcer type interstitial cystitis (IC). METHODS: Dataset acquisitions from Gene Expression Omnibus under platform accession no GSE 11783. We compared global gene expression profiles in bladder epithelial cells from IC patients with Hunner's ulcer corresponding to normal controls. We re-sampling and exploit the correlation structure presented in the dataset through the transcriptional response. For each patient, two bladder biopsies were studied, one from an ulcer area and one from a non-ulcer area. RNA was extracted, and all labeled samples were hybridized to Human Genome U133 Plus 2.0 Array (Affymetrix, CA, USA). RESULTS: The Mahalanobis distance in hierarchical cluster analysis revealed a model of 40 genes expression which is increased in IC and ulcerated IC. Our results can be summarized as follows: First, the expressions of major histocompatibility complex (MHC) class IF and II molecules, leukocyte immunoglobulin-like receptors, hepatitis A virus cellular receptor 2, and interleukin 32 were increased in bladder epithelial from IC and ulcerative IC area. Next, there is an indication of antigen-mediated aggregation of the high-affinity Fc epsilon and gamma RI leading to allergic inflammation through the disease status. Third, the high-affinity Fc gamma RI subunit facilitated T-cell-mediated immune response through the disease status. Such changes, jointly termed "bladder remodeling," can constitute an important long-term consequence of Hunner's ulcer type IC. CONCLUSIONS: Our results indicate that genome-based expression profiling can be used for the diagnostic tests of Hunner's ulcer type IC in clinical practice.

RESUMEN

OBJECTIVE: The aim of this study is to estimate the long-term survival and to identify adverse events associated with the use of Gellhorn pessaries over a 9-year period. METHODS: This was a retrospective case series study at a tertiary urogynecology unit in Taiwan. Between January 2009 and June 2017, 93 patients who opted for self-management Gellhorn pessaries to treat symptomatic pelvic organ prolapse (POP) and who were continuously followed-up were enrolled. Long-term use was defined as use for longer than 1 year. Length of use, factors that predicted discontinuation, and adverse events were analyzed and reviewed by chart or telephone inquiry. RESULTS: The cumulative probabilities of continued pessary use at 1 and 5 years were 62.4% and 47.2%, respectively. Of those who discontinued use, 34 (70.8%) participants discontinued use within 1 year, and the mean duration of use was 13.7 months (range, 0-75 months; median, 5 months). Most of the participants stopped using the pessary because of bothersome adverse events such as pessary expulsion, vaginal pain, de novo urinary incontinence, and erosion/infection. CONCLUSIONS: Self-management Gellhorn pessary was safe and relatively effective and increased patients' autonomy and ability to manage their POP. One third of the patients discontinued use by 1 year, and half of the patients discontinued use at 5 years.

RESUMEN

AIMS: To investigate whether vaginal estrogen cream combined with tolterodine is more effective than tolterodine alone in the treatment of postmenopausal women with overactive bladder (OAB). MATERIALS AND METHODS: This is an unblinded study without placebo. A preliminary study consisted of tolterodine 2 mg twice per day for 3 months had been conducted for 25 postmenopausal women with OAB. Over a period of 11 months, 80 postmenopausal women with OAB underwent a prospective randomized trial. These patients were equally randomized into two groups. The interventions for the 12-week treatment period included 2 mg tolterodine twice per day for the group A and 2 mg tolterodine twice per day/vaginal conjugated equine estrogen 0.625 mg twice a week for the group B. Identical pre- and post-treatment assessments included bladder diary, Urogenital Distress Inventory-6 (UDI-6), and Incontinence Impact Questionnaire-7 (IIQ-7). RESULTS: All 80 women (65.2 years, range 58-73) completed this study. The between groups comparison showed that the group B had significant improvements in mean daytime frequency and voided volume after treatment (14.8-5.8 vs. 14.1-6.4, P = 0.001 and 115.8-141.9 vs. 108.5-134.5, P = 0.007, respectively). Additionally, a comparison of the final total scores of UDI-6 and IIQ-7 between the two groups revealed that the group B had a statistically significant improvement in quality of life than that in the group A (8.6-6.9 vs. 9.5-7.2, P < 0.001 and 9.4-6.1 vs. 10.2-6.5, P < 0.001, respectively). Changes in the other symptoms, including nocturia, urgency and urge incontinence, were not statistically significant but actually achieved improved in both groups. CONCLUSIONS: A combination of vaginal estrogen cream and tolterodine is a potential therapy for postmenopausal women with OAB.

RESUMEN

OBJECTIVE: To investigate the predictors of persistence or resolution of preoperative urgency urinary incontinence (UUI) in women following transvaginal mesh (TVM) repair for advanced pelvic organ prolapse (POP). MATERIAL AND METHODS: Patients with advanced POP undergoing TVM repair between 2008 and 2013 in a tertiary hospital were recruited. All patients underwent evaluation including a structured urogynecological questionnaire, voiding diary, pelvic examination using the POP-quantitation system, and urodynamic testing before and after surgery, and intraoperative cystoscopy. Patient demographics, lower urinary tract symptoms, urodynamic findings, and severity of prolapse were analyzed between women with and without preoperative UUI. RESULTS: Of 174 patients who underwent TVM repair, 49 (28.2%) had preoperative UUI; after operation, 23 (13.2%) were found to have postoperative UUI and 13 (7.5%) developed de novo UUI. For those 49 patients with preoperative UUI, 10 (20.4%) had persistent UUI and 19 (38.8%) developed de novo stress urinary incontinence postoperatively. The prevalence of preoperative bladder outlet obstruction, preoperative maximal cystometric capacity (MCC) < 300 mL, preoperative severe bladder trabeculation, and duration of POP symptoms > 60 months were significantly higher in patients with persistent UUI than without it. Logistic regression demonstrated that preoperative MCC<300 mL, severe bladder trabeculation, and duration of POP symptoms > 60 months were associated with persistent UUI after prolapse repair. CONCLUSION: For women with identified preoperative risk factors, including MCC<300 mL, severe bladder trabeculation, and POP symptoms > 60 months, preoperative counseling should consist of a discussion about persistent UUI symptoms following TVM repair and the development of de novo stress urinary incontinence.

RESUMEN

OBJECTIVE: This was a retrospective study of the efficacy of urethral overdilation (UOD) for women with voiding dysfunction. MATERIALS AND METHODS: Thirty-six patients diagnosed with voiding dysfunction were enrolled. The main indications for UOD included women with poor compliance (30 patients, 83.3%) and obstructive symptoms with high residual urine (6 patients, 16.7%). We utilized a method called UOD (wide caliber), dilating the urethra up to 54 Fr. Patients were re-evaluated every 3 months with serial free flow rate and ultrasound residual in the first year and then as scheduled. Outcome measure was based on the change in videourodynamic parameters, Urogenital Distress Inventory-6 (UDI-6) questionnaire, and International Prostate Symptom Score (IPSS). RESULTS: Mean follow up period of 33.2 months (range: 13-61 months). Failure or success depended on the change in videourodynamic parameters, UDI-6 score, and IPSS. The mean age with the Success Group (n = 22, 61.1%) and Failure Group (n = 14, 39.3%) was 52.8 years and 54.1 years, respectively. Our data showed significant improvements in mean UDI-6 score and IPSS after treatment (11.5-5.7, p = 0.032 and 14.8-5.2, p = 0.006, respectively). By analyzing multiple parameters (age, parity, body mass index, videourodynamics parameters, anesthesia bladder capacity, UDI-6 score, and IPSS) between the success and failure groups, we found only anesthesia bladder capacity reached statistical significance (536 mL vs. 418 mL, p = 0.005). CONCLUSION: The present study provides evidence that UOD, as a minimally invasive procedure, achieves a satisfactory cure rate on short-term follow-up for women with voiding dysfunction.
