OBJECTIVETo verify the effect of electroacupuncture (EA) for female stress urinary incontinence (SU).

METHODSForty-two patients were randomly divided into an observation group(20 cases) and a control group (22 cases). EA at Zhongliao (BL 33) and Huiyang (BL 35) was used in the observation group. Sham acupuncture at non meridian points, one can beside Zhongliao (BL 33) and Huiyang (BL 35), was applied, and placebo EA was adopted in the control group. Treatment with needle retained for 30 min a time was given once every other day and three times a week for continuous six weeks in the two groups. Urinary and reproductive simple score (UDI),visual analogue scale (VAS) and the frequency of nocturnal enuresis were observed before treatment, at the second, forth and sixth week of treatment in the two groups, and the efficacy was compared.

RESULTSThe effective rates of the observation group were 80.0% (16/20), 95.0% (19/20) and 95.0% (19/20), which were better than 40.9% (9/22), 31.8% (7/22) and 27.3% (6/22) of the control group at the second, forth and sixth week of treatment. The differences were statistically significant between the two groups (all P < 0.05). After treatment in the observation group, the results of UDI, VAS and frequency of nocturnal enuresis were improved compared with those before treatment (all P < 0.05). Along with treatment, all indices were gradually improved, and the change at the sixth week was the most obvious in observation group. The results of the observation group were better than those of the control group at all times (all P < 0.05).

CONCLUSIONEA achieves obvious effect for female SUI, and effectively improves the lower urinary trace symptoms, the degree of urinary incontinence and the frequency of nocturnal enuresis. The effect becomes increasingly better along with treatment within six weeks.

PURPOSE: The definition of posttransobturator tape procedure (post-TOT) voiding dysfunction (VD) is inconsistent in the literature. In this study, we retrospectively investigated the risk factors for post-TOT VD by applying various definitions in one cohort. MATERIALS AND METHODS: The medical records of 449 patients were evaluated postoperatively. Acute urinary retention requiring catheterization, subjective feeling of voiding difficulty during follow-up, and postoperative postvoid residual (PVR) greater than 100 mL or PVR greater than 50% of voided volume (significant PVR) were adopted for the definition of VD. With these categories, multivariate analysis was performed for risk factors of postoperative VD. RESULTS: Ten patients (2.2%) required catheterization, 47 (10.5%) experienced postoperative voiding difficulty, and 63 (14.7%) showed significant PVR. In the multivariate logistic analysis, independent risk factors for postoperative retention requiring catheterization were previous retention history (p=0.06) and preoperative history of hysterectomy. Risk factors for subjective postoperative voiding difficulty were underactive detrusor (p=0.04) and preoperative obstructive voiding symptoms (p<0.01). Previous urinary retention history (p<0.01)) was an independent risk factor for concomitant postoperative voiding difficulty and significant PVR. Spinal anesthesia (p=0.02) and previous urinary retention history (p=0.02) were independent risk factors for significant postoperative PVR. CONCLUSIONS: With the use of several definitions of VD after the midurethral sling procedure, postoperative peak flow rate and PVR were significantly different between groups. Although there were no independent risk factors consistent with various definitions of VD, preoperative obstructive voiding symptoms and objective parameters suggesting impaired detrusor tend to have predictive power for post-TOT VD.

OBJECTIVETo compare the difference in the clinical efficacy on mild and moderate female stress urinary incontinence (FSUI) between transcutaneous acupoint electrical stimulation and oral administration of midodrine hydrochloride tablets.

METHODSNinety cases of mild and moderate FSUI were randomized into an observation group and a control group, 45 cases in each one. In the observation group, the transcutaneous acupoint electrical stimulation was applied to Ciliao (BL 32), Shenshu (BL 23), Zigong (EX-CA 1), Guanyuan (CV 4) and Qihai (CV 6), once a day. In the control group, midodrine hydrochloride tablets were prescribed for oral administration, 2. 5 mg per treatment, three times each day. The duration of treatment was 4 weeks. The score of international consultation on incontinence questionnaire-urinary incontinence short form (ICI-Q-SF) and leakage of urine in 1 h urinal pad test were observed before and after treatment in the patients of the two groups, and the efficacy was compared between the two groups.

RESULTSThe score of ICI-Q-SF and leakage of urine in urinal pad test after treatment were all improved apparently as compared with those before treatment in the two groups (all P<0. 01), and the results in the observation group were better than those in the control group (both P<0. 01). The total effective rate was 86. 7% (39/45) in the observation group, which was better than 68. 9% (31/45, P<0. 05) in the control group.

CONCLUSIONThe transcutaneous acupoint electrical stimulation achieves the better efficacy on FSUI as compared with the oral administration of midodrine hydrochloride tablets. This therapy effectively improves the patient's urine control ability and reduces leakage of urine.

PURPOSE: Stress urinary incontinence (SUI) is one of the most common lower urinary tract symptoms in women. We analyzed age-associated changes in urodynamic parameters in women with SUI. MATERIALS AND METHODS: We analyzed the urodynamic study (UDS) results of patients with urodynamically proven SUI between March 2008 and July 2014. In uroflowmetry, maximal flow rate (Qmax), time to Qmax, voided volume, and postvoid residual urine volume (PVR) and filling cystometry data including first, strong desire to void and Valsalva leak point pressure (VLPP) were measured. Also, Qmax and detrusor pressure at Qmax (Pdet@Qmax) of voiding cystometry data were analyzed. RESULTS: The subjects included 776 patients. Among the patients, 151 were withdrawn because of incomplete UDS data or because they met the exclusion criteria. A total of 625 patients enrolled in our study. The mean age of the population was 57.3 years. The mean Qmax, voided volume, voiding time, and PVR were 26.2 mL/s, 292.1 mL, 25.7 s, and 31.7 mL, respectively. Qmax (p=0.001) in uroflowmetry, PVR (p=0.042), first desire to void (p=0.042), Pdet@Qmax (p=0.016), and the bladder contractility index (p=0.046) were significantly different between the age groups. Qmax and Pdet@Qmax were decreased and PVR was increased significantly with age after 60 years. CONCLUSIONS: Older women with SUI also have worsened voiding function with age as the results of urodynamic parameters. Specifically, detrusor contractility decreased with age after 60 years.

PURPOSE: We assessed the impact of transobturator tape (TOT) treatment on overactive bladder (OAB) symptoms with a particular focus on nocturia in patients with mixed urinary incontinence (MUI). MATERIALS AND METHODS: In this retrospective cohort study, the medical records of 237 women who underwent TOT surgery for the treatment of MUI were reviewed. Of these, 86 patients (36.4%) had preoperative nocturia. Patients with neurological diseases or sleep disorders that could affect the voiding pattern were excluded. Patients who were being treated with anticholinergics and antidiuretic hormones were also excluded, which left 70 subjects eligible for analysis. Pre- and postoperative evaluations consisted of a physical examination, 3-day frequency-volume chart, and health-related quality of life questionnaires (King's health questionnaire, overactive bladder symptom score, and OAB-questionnaire). RESULTS: TOT treatment resulted in an overall significant improvement in OAB symptoms including nocturia. Frequency-volume charts revealed that TOT treatment significantly decreased the actual number of nightly voids (ANV) and the nocturnal bladder capacity index (NBCi) in the entire cohort. However, in a subgroup of women with nocturnal polyuria, there was no significant change in ANV or NBCi after the sling operation. Correlation analysis of the whole cohort revealed that the postoperative changes in NBCi correlated positively with postoperative changes in ANV. The nocturia-persisting group was more likely to have nocturnal polyuria and lower preoperative functional bladder capacity compared with the nocturia-improved group (p=0.024 and p=0.023, respectively). CONCLUSIONS: Our results demonstrated that the TOT procedure resulted in an overall significant improvement in OAB symptoms including OAB-related nocturia in patients who presented with MUI.

PURPOSE: Urodynamic studies are commonly performed as part of the preoperative work-up of patients undergoing surgery for stress urinary incontinence (SUI). We aimed to assess the extent to which these urodynamic parameters influence patient selection and postoperative outcomes. MATERIALS AND METHODS: Patients presenting with SUI were randomly assigned to two groups: one undergoing office evaluation only and the other with a preoperative urodynamic work-up. Patients with unfavorable urodynamic parameters (detrusor overactivity [DO] and/or Valsalva leak point pressure [VLPP]<60 cm H2O and/or maximum urethral closure pressure [MUCP]<20 cm H2O) were excluded from the urodynamic testing group. All patients in both groups underwent the transobturator midurethral sling procedure. Evaluation for treatment success (reductions in urogenital distress inventory and incontinence impact questionnaire scoring along with absent positive stress test) was done at 6 months and 1 year postoperatively. RESULTS: A total of 72 patients were evaluated. After 12 patients with any one or more of the abnormal urodynamic parameters were excluded, 30 patients were finally recruited in each of the "urodynamic testing" and "office evaluation only" groups. At both the 6- and the 12-month follow-ups, treatment outcomes (reduction in scores and positive provocative stress test) were significantly better in the urodynamic testing group than in the office evaluation only group (p-values significant for all outcomes). CONCLUSIONS: Our findings showed statistically significantly better treatment outcomes in the urodynamic group (after excluding those with poor prognostic indicators such as DO, low VLPP, and MUCP) than in the office evaluation only group. We recommend exploiting the prognostic value of these urodynamic parameters for patient counseling and treatment decisions.

BACKGROUNDOccult stress urinary incontinence may lead to de novo stress urinary incontinence after pelvic floor repair surgery. A measurement of pudendal nerve terminal motor latency can reflect the integrity of the nerves. We aimed to explore the value of pudendal nerve terminal motor latency in the diagnosis of occult stress urinary incontinence in pelvic organ prolapse patients.

METHODSTen patients with stress urinary incontinence (SUI group), 10 with SUI and uterine or vaginal prolapse (POP + SUI group) and 10 with uncomplicated uterine or vaginal prolapse (POP group) were evaluated for their pudendal nerve terminal motor latency using a keypoint electromyogram.

RESULTSThe amplitude of positive waves was between 0.1 and 0.2 mV. The nerve terminal motor latency was between 1.44 and 2.38 ms. There was no significant difference in the wave amplitudes of pudendal nerve evoked action potential among the three different groups (P > 0.05). The pudendal nerve latency of the SUI group, POP + SUI group and POP group were (2.9 ± 0.7) seconds, (2.8 ± 0.7) seconds and (1.9 ± 0.5) seconds respectively. The difference between the SUI group and POP + SUI group was not statistically significant (P > 0.05), whereas the difference between the SUI and POP groups and between the POP + SUI and POP groups were statistically significant (P < 0.05). There was a positive correlation between pudendal nerve latency and the severity of SUI; the correlation coefficient was 0.720 (P < 0.01).

CONCLUSIONSPatients with SUI may have some nerve demyelination injuries in the pudendal nerve but the damage might not involve the nerve axons. The measurement of pudendal nerve latency may be useful for the diagnosis of SUI in POP patients.

To evaluate the effectiveness of the human umbilical cord blood (HUCB) transplantation for the treatment of intrinsic sphincter deficiency (ISD), we analyzed the short term effects of HUCB mononuclear cell transplantation in rats with induced-ISD. ISD was induced in rats by electro-cauterization of periurethral soft tissue with HUCB mononuclear cell injection after 1 week. The sphincter function measured by mean leak point pressure was significantly improved in the experimental group compared to the control group at 4 weeks. (91.75+/-18.99 mmHg vs. 65.02+/-22.09 mmHg, P=0.001). Histologically, the sphincter muscle was restored without damage while in the control group it appeared markedly disrupted with atrophic muscle layers and collagen deposit. We identified injected HUCB cells in the tissue sections by Di-I signal and Prussian blue staining. HUCB mononuclear cell injection significantly improved urethral sphincter function, suggesting its potential efficacy in the treatment of ISD.

OBJECTIVETo observe the clinical effect of dog-day acupuncture and tortoise-shell moxibustion combined with pelvic floor muscle exercises for treatment of female stress urinary incontinence.

METHODSSeventy one cases were randomly divided into two groups. Thirty six cases in the observation group were treated with acupuncture on Zhongji (CV 3), Zigong (EX-CA 1), Chize (LU 5) etc. and tortoise-shell moxibustion on Shenque (CV 8) combined with pelvic floor muscle exercises; while thirty five cases in the control group were treated with only pelvic floor muscle exercises. The scores of the International Consultation Committee on Incontinence Questionnaire Short Form (ICI-Q-SF) and the Medical Outcomes Survey Short Form-36 (SF-36) were evaluated before and after treatment, and the scores of SF-36 were also compared with 35 cases in normal group.

RESULTSThe total effective rate of 91.7% in the observation group was higher than that of 77.1% in the control group (P < 0.05). The dimensions of SF-36 of stress urinary incontinence patients were remarkably lower than those of normal group (all P < 0.05). The scores of ICI-Q-SF were decreased while the scores of SF-36 were increased obviously after treatment in both the observation group and the control group, there were pronounced improvements on physiological function, pain, physical activity, social function and affection function in the observation group (all P < 0.05).

CONCLUSIONThe quality of life for female stress urinary incontinence patients may be poor, however the dog-day acupuncture and tortoise-shell moxibustion combined with pelvic floor muscle exercises can improve the symptoms of urinary incontinence and increase the quality of life of patients.
