Objective To elucidate the MRI appearance of prostatic abscess,the DWI and enhanced MRI features.Methods 12 cases of prostatic abscesses were retrospectively analyzed,the clinical symptom mainly manifested as lower urinary tract symptoms and fever.All of the patients were given routine MR examination including DWI sequence,6 patients received further enhanced MR examination.Results In the 12 cases,there were 4 cases behaved as single type,8 cases as multifocal type.The abscess showed iso-or slightly hypo-signal intensity on T1 WI,hyper-signal intensity on T2 WI,markedly high signal intensity on DWI and correspond-ing markedly low signal intensity on ADC.Complete abscess walls showed iso-or slightly hyper signal on T1 WI,hypo-signal inten-sity on T2 WI.The mature abscess walls were thin and smooth,which showed homogeneously ring enhanced in 4 cases.The imma-ture abscess walls showed uneven thickness and moderately enhanced in 2 cases.Septum in the abscess could be found in 4 cases, which showed similar enhancement to the abscess walls,while the abscess cavity showed non-enhanced.Abscesses involved the sur-rounding structures in 2 cases,the involved area showed obvious hyper-signal on T2 WI fat-suppression sequence.Conclusion DWI is the best sequence in the diagnosis of prostatic abscess,the markedly high signal intensity on DWI is the characteristic sign.The enhanced MRI showed the walls and septa clearly,the extent and involvement of adjacent structures.The multi-parametric MRI is a prominent procedure in the diagnosis of prostatic abcess.

Objective To study the effect of point electric stimulation for urinary incontinence after postoperative cerebral hemorrhage.Methods Eighty patients with urinary incontinence after postoperative cerebral hemorrhage were randomly divided into treatment group and control group(n=40 case). Point electric stimulation was given to the treatment group, and Oxybutynin hydrochloride sustained release tablets was given orally to the control group. Index of urinary diary and bladder capacity in both groups before treatment and after 3 weeks of treatment were observed.Results After 3 weeks of treatment,the total effective rate(87.2%vs. 65.8%,χ2=4.916) in the treatment group were better than the control group (P<0.05). The times of voided (10.15 ± 2.21 times/24 hvs. 18.63 ± 3.42 times/24 h,t=12.956), the times of urinary incontinence (2.18 ± 1.04 times/24 h vs. 6.19 ± 2.16 times/24 h,t=10.421), the average voided volume (293.38 ± 16.32 mlvs. 180.82 ± 15.43 ml, t=31.083), the initial sensory capacity of bladder (276.73 ± 20.95 mlvs. 186.43 ± 21.14 ml,t=18.825), the maximum capacity of bladder (492.81 ± 23.72 mlvs. 293.81 ± 24.46 ml,t=36.244), the residual urine volume(13.25 ± 5.83 mlvs. 34.63 ± 6.25 ml,t=15.527) in the treatment group were significantly better than those in the control group (P<0.01).Conclusions The treatment of point electric stimulation can reduce the symptoms of urinary incontinence.

Objective To explore the biomechanical characteristics of the pharynx in patients with aspiration after radiotherapy for nasopharyngeal carcinoma (NPC).Methods Clinical data on NPC patients with dysphagia admitted between July 2011 and June 2015 were retrospectively analyzed.Twenty-three patients were found who had received videofluoroscopic swallowing studies (VFSSs) and whose pharyngeal pressure and upper esophageal sphincter (UES) relaxing were tested using high-resolution solid-state manometry (HRM).The cases were divided into an aspiration group and a non-aspiration group according to the VFSS results.Differences in biomechanical parameters between the 2 groups when taking food of different viscosity were compared.Results Patients with aspiration had significantly higher UES residual pressure when taking thick liquids (20.1± 14.3 mmHg) and paste (18.0± 14.3 mmHg) than patients not aspirating (9.3±9.2 mmHg and 7.2±8.9 mmHg for thick liquid and paste respectively).But no significant difference in average pharyngeal pressure between the two groups was observed.Conclusion Aspiration after radiotherapy may be correlated with increased UES residual pressure.

Objective To observe the location of pelvic organs, the morphology and function of levator ani muscle (LAM) in primiparous women post vaginal delivery at 6 months postpartum using static and dynamic MRI, and investigate the correlation between LAM injury and pelvic organ prolapse (POP). Methods A perspective analysis of static and dynamic MRI was performed in fifty-one primiparous women post vaginal delivery at 6 months postpartum and thirty-five nulliparous women without experience of pregnancy and delivery as control group from June 2014 to January 2015. Previous pregnancy and abortion history, previous pelvic surgery and pelvic mass diseases were excluded. Cases with pelvic floor dysfunction symptoms were excluded from the control group. All of the women underwent static and dynamic MRI. The primiparous group was divided into two groups on presence or absence of POP on MRI findings:primiparous POP group and primiparous control group. The levatorani scoring system based on static MRI was used to characterize morphological changes of LAM into none, minor and major injury by the total score of bilateral LAM. A series of parameters including H line (the distance between the inferior margin of pubic symphysis to anorectal junction), M line (the perpendicular distance between the distal end of H line to pubococcygeal line), levator plate angle (LPA), iliococcygeal angle (ICA), and levator hiatus length and area were measured on static and dynamic MR images. Fisher exact test was performed to compare difference in distribution of the LAM injury between the primiparous group and control group, as well as the primiparous POP group and primiparous control group. Independent sample t test or Mann-Whitney test was used to compare difference in LAM parameters between the primiparous POP group and primiparous control group. Results In the 51 cases primiparous group, 44 cases showed none injury, whilst 5 cases with minor and 2 cases with major injury in the puborectal muscle. Thirty two cases showed none injury, whilst 10 cases with minor and 9 cases with major injury in the iliococcygeal muscle. In the 35 cases control group, none injury was shown in puborectal muscle, whilst 32 cases with none, 2 cases with minor and 1 case with major injury in the iliococcygeal muscle. There was no significant difference in the puborectal muscle injury between the two groups (P=0.203), and there was significant difference in the iliococcygeal muscle injury between the two groups (P<0.05). In the 24 cases primiparous POP group, 20 cases showed none injury, whilst 2 cases with minor and 2 cases with major injury in the puborectal muscle. Fourteen cases showed none injury, whilst 6 cases with minor and 4 cases with major injury in the iliococcygeal muscle. In the 27 cases primiparous control group, 24 cases showed none and 3 cases with minor injury in the puborectal muscle, whilst 18 cases with none, 4 cases with minor and 5 cases with major injury in the iliococcygeal muscle. There was no significant difference in the puborectal muscle injury and iliococcygeal muscle injury between the two groups (P=0.588 and 0.559, respectively). The LH during Valsalva status in primiparous POP group and primiparous control group were (6.7 ± 1.1) and (5.0 ± 0.6) cm, respectively, whilst the LHA was (41.6 ± 12.6) and (24.2 ± 5.5) cm2. There were significant difference between the corresponding groups (P=0.042 and 0.004, respectively). There was no significant difference between the corresponding groups of the other LAM parameters on static and dynamic MRI (all P>0.05). Conclusion Vaginal delivery may cause various degrees of LAM injury, the LAM functional deficiency were observed in primiparous women combined with POP.
