ABSTRACT
Objective To study the value of renal CT scan in evaluating split renal function.Methods 147 patients undergone CT scan from June 2009 to June 2011 were involved in this study.There were 73 cases of obstructive hydronephrosis and 74 cases of renal tumors.66 patients were males and 81 were females with a mean age of 53 years ( range 17 - 87 years).GFR detected by single-photon emission computed tomography (SPECT) was used as the reference of split renal function.The kidneys were divided into 3 groups according to the GFR:normal renal function (113 cases,GFR ≥ 34 ml/min),mildly impaired renal function (66 cases,GFR:20 -34 ml/min) and severely impaired renal function (41 cases,GFR ＜20 ml/min).One-way ANOVA and linear regression analysis were used to analyze the relationship between the results of CT scan and split renal functions. Results There were significant differences in the cortical thickness among the normal renal function,mildly impaired renal function and severely impaired renal function groups.The cortical thicknesses were (0.62 ±0.11) cm,(0.45 ±0.10) cm and (0.26 ±0.07) cm,respectively (P ＜ 0.01 ).The renal cortical thickness was strongly correlated with GFR (r =0.806,P ＜0.01 ).There were significant differences in the enhancement during the cortical phase among the 3 groups,which were (162.1 ±25.3) HU,(121.6 ±21.0) HU and (63.5 ±20.0) HU,respectively (P＜0.01).The enhancement during the cortical phase was strongly correlated with the GFR (r =0.851,P ＜ 0.01 ).The enhancement during the parenchymal phase and excretory phase was moderately correlated with the GFR ( r =0.467 and r =0.451,P ＜ 0.01 ). Conclusions The renal cortical tbickness and the enhancement during the cortical phase detected by CT scan might be useful for the clinical evaluation of split renal function.
ABSTRACT
Objective To evaluate the efficacy and safety of solifenacin in patients with overactive bladder (OAB). Methods A multicenter clinical trial was conduced. 216 patients with OAB were enrolled. All the patients received solifenacin(5 mg once daily). With 5 weeks'treatment, all the patients recorded the diary and the adverse events as well. The symptoms of urgency, frequency, nocturia, urine volume, incontinence were evaluated. The results of the efficacy and safety were analyzed by using SPSS 13. 0. Results After 5 week treatments, all the index obviously improved(P<0.05). 187 cases (86.7%)were cured and 43 cases recovered normal voiding, 29 cases improved obviously. 11cases(5.0 %)reported adverse effect as dry mouth, dry eye. Conclusion Solifenacin could be the safe and effective drug in the treatment of OAB patients.
