Objective · To investigate the relationship between the results of thin prep cytologic test (TCT), high-risk human papillomavirus (Hr-HPV) detection and vaginalintraepithelial neoplasia (VAIN) after hysterectomy. Methods · A retrospective study was conducted of 56 patients with VAIN after hysterectomy. The analysis included TCT and Hr-HPV examination, clinical data and the relationship between Hr-HPV examinenation and histopathological examination of colposcopy. Results · Postoperative follow-up of TCT and Hr-HPV parallel pathological examination showed that 56 patients had vaginal stump lesions, including cervical factor hysterectomy accounted for 5.81% (45/775) and non cervical factor hysterectomy accounted for 0.19% (11/5933). The difference was statistically significant (P=0.000). In 56 cases of patients with vaginal stump lesions, Hr-HPV infection were 40 cases (accounting for 71.43%), uninfected patients were 16 cases (accounting for 28.57%). The Hr-HPV infection rates of cervical hysterectomy and non cervical factor hysterectomy patients were 80.00% (36/45) and 36.36% (4/11) respectively, and the difference was statistically significant (χ2= 6.248, P=0.012). TCT results showed that the incidence of squamous intraepithelial lesions were 42.22% (19/45) and 9.09% (1/11) respectively. Conclusion · The Hr-HPV infection rate and the morbidity of VAIN of the patients undergone hysterectomy due to the cervical lesionfactors is higher than those who had none cervical lesion factors. In order to identify VAIN early, patients who have the history of hysterectomy should undergo careful evaluation of cervical and vaginal circumstance before surgery and the routine examinations of TCT and Hr-HPV in the follow-up.

Purpose: Transcutaneous electrical neural stimulation (TENS), as a non-invasive modality, has been clinically used as an alternative treatment for children with overactive bladder (OAB). We conducted a pooled analysis to explore the effect of TENS on OAB. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analysis guideline was followed in this study. The MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases, as well as the reference lists of the retrieved studies, were used to find trials relevant for assessing the use of TENS to treat OAB. Results: Of the 246 records identified, 8 publications were analyzed in our study. Our analysis found that TENS resulted in a greater decrease of wet days/wk, daily voiding frequency, daily incontinence episodes, and daily number of voids than was observed in the control group. Furthermore, TENS-treated patients showed similar visual analogue scale (VAS) scores to patients in the control group, demonstrating that the application of TENS did not increase patients’ discomfort and pain. TENS had a relative advantage in the number of partial responses, but no clear differences were found in frequency of no response or a full response compared to the control group. In urodynamic testing, TENS led to obvious improvements in average voided volume and maximum voided volume in children with OAB. Conclusions TENS had a remarkable effect on the improvement of urodynamic indexes and objective OAB symptoms without a significant increase in VAS scores for children with OAB.
