Objective To study the effect of remote limb isehemic postconditioning (RLIPC) on posterior circulation ischemia vertigo (PCIV). Methods Seventy patients with PCIV, admitted to our hospital from January 2013 and June 2014, were randomly divided into control group and therapy group (n=35). The patients of control group were treated with routine medicine, and those of therapy group were treated with RLIPC and routine medicine. Before and after treatment, dizziness assessment rating scale (DARS) and dizziness handicap inventory (DHI) scale were used to evaluate the changes of manifestations; peak systolic velocity (PSV) and end diastolic velocity (EDV) of vertebra artery (VA) were evaluated by colour doppler ultrasound. Results Before treatment, no significant differences on DARS and DHI scores were noted between the two groups (P>0.05); after treatment, , the DARS and DHI scores in the therapy group were 26.03±4.24 and 60.91±10.15, respectively, which were significantly decreased as compared with those in the control group (28.80±5.16 and 68.11±12.44, t=2.388 and 2.584, P=0.000); PSV and EDV of VA in the therapy group were 49.97±7.69 and 16.90±2.80, respectively, which were significantly increased as compared with those in the control group (47.31±7.47 and 15.12± 2.74, t=-2.505 and-2.631, P=0.015 and 0.011). Conclusions RLIPC could alleviate the symptoms of PCIV, which might be related to increased blood flow of VA. RLIPC is simple and safe, and can be used in the treatment of PCIV.

Objective:To explore the outcomes of urethra around corpora cavernosus anastomotic urethroplasty for the treatment of complex posterior urethral strictures.Methods:Between June 2008 and June 2020, 35 patients with complex posterior urethral strictures were treated using urethra rerouted under one corpora cavernosus anastomotic urethroplasty. The patients’ age was 3-54 years(mean 23.2 years), the urethral stricture or loss length was 4-7 cm(mean 5.2 cm), and 6 patients associated with urethrorectal fistula. The technique involved: ①The anterior urethra is dissected long more than 5 cm, separation of the proximal corporeal bodies, inferior pubectomy and the dissected proximal urethra.②A channel around the left crus of the penis through the inferior pubectomy is separated and urethra rerouted under left corpora cavernosus to allow a tension-free anastomosis to the proximal urethra.Results:Two patients lost follow-up; the remainder 33 patients were followed-up for 3 to 144 months(mean 37 months). Thirty-two patients could void normally(97%), The examination of maximal urinary flow rates(Q max) were taken in 21 patients, of whom Q max was 13.6-35.5 ml/s (mean 17.5 ml/s) in 7 children and 16.3-77.6 ml/s(mean 27.9 ml/s) in 14 adult patients. All 6 patients associated with urethrorectal fistula successful repaired, of these patients 1 had died of hemorrhage of brain 6 years postop. One patient developed urethral stenosis postoperatively. Continence was achieved in 29 patients, the remaining 3 patients had incontinence from mild to moderate. Conclusions:Urethra rerouted under left corpora cavernosus anastomotic urethroplasty is not only an effective surgical salvage option, with low recurrent rate for patients with complex posterior urethral strictures, but also do not cause curve and affect growth of corpora cavernosus.
