ObjectiveTo investigate the effects and indication of intermittent catheterization(IC) by relative safe bladder capacity(RSBC) to treat vesical-ureteral reflux(VUR).MethodsThere were 23 male complete SCI patients, aged between 7～45 years, including 15 patients without vesicao-ureteral reflux injuried 1～3 months as control group, 3 patients in mild group affected only ureter, and 5 patients in severe group affected not only ureter but also the pelvis. All the patients were taken intermittent catheterrization according to their own RSBC companied with supersonic device. The times of IC per day is that the average total urine volume one day was divided by RSBC. The observation time is over 2 years. During the oberservation some medicine was used to enlarge some patients bladder capacity.ResultsThere were no reflux in the control group; the reflux in the mild group improved a lot, some even disappeared, and there were no change in the severe group.ConclusionIC by RSBC is effective to prevent and cure vesical-ureteral reflux in some SCI patients.

Objective To observe the effect of Boari bladder muscle flap surgery in nephron sparing surgery for patients with middle and lower ureteral carcinoma. Methods Totally 80 patients with middle and lower ureteral carcinoma underwent surgery in our hospital from March 2009 to March 2012 were selected and divided into the control group and the observation group,with 40 cases in each group. Patients of the control group were treated with ureteral carcinoma radical prostatectomy while patients of the observation group were treated with Boari bladder muscle flap surgery,and all of them were followed up for 3 years after operation. Observed the renal function,renal tumor markers and the level of inflammatory symptoms of the 2 groups before the operation and 3 months after the operation,and compared the long-term progno-sis of the 2 groups. Results There was no significant difference between the 2 groups in renal function index before operation. The level of BUN,Scr,blood urea and serum uric acid index in the 2 groups were all increased compared with those before operation,but the increase of the control group was significantly higher with statistically significant differences (P<0. 05). The tumor markers CA19-9, Survivin and in-flammatory marks WBC,NEC%,IL-6,hs-CRP had no significant difference before operation,and all the level of the 2 groups were decreased after operation,but there was still no difference between the 2 groups (P>0. 05). The survival rate 1 year,2 years and 3 years after operation also had no significant difference between the 2 groups (P>0. 05). Conclusion The use of Boari bladder muscle flap surgery in nephron sparing surgery for patients with middle and lower ureteral carcinoma can effectively maintain the renal function of patients without affecting the radical and long-term prognosis.
