ABSTRACT
Objective To evaluate the short-term effect of pelvic floor muscle rehabilitation training under the guidance of doctors on children with neuropathic acontractile sphincter incontinence ( NASI ).Methods Sixty eighty children[aged 4 - 12 ( mean, 7 ) years]with NASI were selected.All children were randomly divided into multiple guidance group and single guidance group.Pelvic floor muscle rrehabilitation training was successfully accomplished in all children.Three-day urinary diary, 7-day fecal diary, the ICI-Q-SF score and urodynamic evaluations were completed before and after the treatment.Three months later, follow-up was carried out.The results were compared between the groups.Results After treatment,TOV, LT, TFI and ICI-Q-SF of multiple guidance group were significantly lower than those of single guidance group[(29±8) vs (34±12), (19±10) vs (25 ±12), (1.9±1.1) vs (2.5 ±1.3), (9±5) vs ( 12 ± 6 ), P ＜ 0.05], however, PMUC of multiple guidance group was significantly higher than those of single guidance group[(5.6 ± 2.0 ) vs (4.7 ± 1.7 ), P ＜ 0.05].The effective rate of multiple guidance group after treatment and at follow-up were respectively 79.4% and 70.6% , significantly higher than those of single guidance group ( 64.7% and 50.0%, P ＜ 0.05 ).Conclusion Pelvic floor muscle rehabilitation training under the guidance of doctors has satisfactory therapeutic efficacy on the children with NASI.
ABSTRACT
Objective To analyze the value of multi-slice spiral CT (SCT) scan in staging and subtyping of renal cell carcinoma (RCC). Methods The preoperative kidney SCT data and postoperative pathology results of 64 patients with RCC were retrospectively analyzed. The patients′ ages ranged from 33-78 years (average 54 years). There were 44 males and 20 females in the study group. According to the CUA Guidelines, the staging and subtyping of RCC were performed through the combined information of preoperative SCT attenuation in unenhanced, corticomedullary phase and enhancement pattern. The results were compared with the postoperative histopathological results. Results The SCT results showed 38 cases were clear cell RCC, 14 cases were papillary RCC and 12 cases were chromophobic cell RCC. Histopathological results showed that 40 cases were clear cell RCC, 16 cases were papillary RCC and 8 cases were chromophobic cell RCC. According to the standard of 40 HU of CT attenuation value, the sensitivity, specificity and accuracy were 75%, 79% and 78% for diagnosis of papillary RCC in the unenhanced phase. The sensitivity, specificity and accuracy by the standard of 90 HU of CT attenuation value was 90%, 88% and 89% for diagnosis of clear cell RCC in the corticomedullary phase. In chromophobic RCC, homogeneous enhancement was more common than in papillary RCC and clear cell RCC. There was no significant difference of staging and subtyping of RCC between SCT and pathological results (P>0.05). The accuracy of SCT in staging and subtyping of RCC was 88% in staging, and 89% in subtyping. Conclusions SCT is a useful preoperative tool to stage and subtype RCC
ABSTRACT
Objective To evaluate the relationship between ultrasound-assayed detrusor thickness and bladder outlet obstruction (BOO) in old men with benign prostatic hyperplasia (BPH).Methods The 106 BPH patients underwent the urodynamic examination on which the diagnosis of BOO was dependent. The obstruction was defined as the Abrams-Griffiths nomogram (A-G index)≥40 and the grade of linear passive urethral resistance relation (LinPURR)≥Ⅱ . When bladder capacity reached 150 ml, the detrusor thickness was measured by abdominal ultrasound. Results Compared with unobstructed group, the maximum flow rate and average flow rate were both lower in obstructed group [(10.1±3.0) ml/s vs. (17.4±3.1) ml/s, (5.5±2.2) ml/s vs. (11.2±2.2) ml/s, t= 10.26and 11.03, both P＜0.01]. And the residual urine volume and maximum detrusor pressure were significantly higher in obstructed group than in unobstructed group [(47.6 ± 24.3) ml vs. (17.0 ±5.6) ml, (39.3±14.4) cm H2Ovs. (26.8±8.0) cm H2O, t=6.32 and 4.07, P＜0.01 or 0.05].Detrusor thickness was positively correlated with maximum detrusor pressure (r= 0.419, P＜0.01),but negatively correlated with maximum flow rate (r =- 0.749, P＜ 0.01 ), mean flow rate (r=-0.853, P＜0.01) and voided volume (r=-0.556, P＜0.01). There was significant difference in detrusor thickness between obstructed group and unobstructed group [(3.0± 0.2) mm vs. (2.5 ±0.2) mm, t= 11.2,P＜0.05]. According to the diagnostic standard of detrusor thickness≥3.0 mm,it had a sensitivity of 90% and a specificity of 84.6%, a positive predictive value of 93.1% and a negative predictive value of 78.6%. Conclusions Detrusor thickness of 3.0 mm or greater has a certain predictive value for BOO in old men.
