Biomechanical mechanism and treatment strategy of female bladder prolapse / 现代泌尿外科杂志

Bladder prolapse is a common disease in female,which seriously affects the physical and mental health of patients. At present,numerous treatment methods can improve the condition to some extent,but the therapeutic effect is still not satisfactory. This paper probes into the etiology of bladder prolapse from the perspective of biomechanics,explores the relationship between bladder prolapse and stress injury,and proposes corresponding treatment strategies for better management of this disease.

Research advances on pelvic floor deformation characteristics and biomechanical axial in apical suspension / 现代泌尿外科杂志

Female pelvic organ prolapse (POP) is caused by damage or loss of pelvic floor support, resulting in displacement of the pelvic organs, which leads to abnormalities in the position and function of the organs, mainly due to damage to the pelvic floor mechanical support structures caused by transvaginal birth, loss of elasticity of the pelvic floor mechanical support structures in old women, and loss of the ability to maintain the pelvic floor. The key to POP surgery is the repair of the apical vagina, but treatment based on this theory has failed to achieve satisfactory clinical outcomes. This article will analyze the common procedures of apical suspension in the treatment of mid-pelvic prolapse from the perspective of pelvic floor morphological features and pelvic floor biomechanics axially.

Modified transobturator tape for female stress urinary incontinence / 中华泌尿外科杂志

Objective To explore the efficacy and safety of modified transobturator tape (TOT) for female stress urinary incontinence (SUI).Methods From June 2015 to June 2017,a total of 87 SUI patients,including 35 patients underwent standard TOT operation (standard TOT group) and 52 patients underwent modified TOT operation (modified TOT group),were retrospectively reviewed.There was no statistical difference of age [(59.7 ± 10.3) yea~ vs.(56.3 ± 9.1) years],BMI [(24.I ± 9.7) kg/m2 vs.(24.6 ± 9.3) kg/m2],diabetes history [31.4％ (11/35) vs.26.9％ (14/52)],mixed urinary incontinence [45.7％ (16/35) vs.48.1％ (25/52)] and the daily amount of urine pad [(4.3 ±2.7) vs.(3.9 ± 2.1)] between the two groups (P ＞ 0.05).The operative time,intraoperative complications,and postoperative complications were collecteded in two groups.Patients were followed up at 3 months,6 months,and 1 year after surgery.Results There was no significant difference in operation time [(21.1 ± 4.3) min vs.(20.5 ± 5.7) min],intraoperative hemorrhage [(18.3 ± 9.1) ml vs.(25.7 ± 8.3) ml] and postoperative incidence of urinary retention [2.9％ (1/35) vs.3.8％ (2/52)] between the two groups (P ＞ 0.05).The incidence of postoperative leg pain was significantly lower in modified TOT group than in TOT group[1.9％ (1/52) vs.20.0％ (7/35),P ＜ 0.05].There was no significant difference in subjective cure rate and objective cure rate between the two groups at 3 months,6 months and 1 year after surgery (P ＞ 0.05).Conclusions Compared with the standard TOT,the modified TOT of modified puncture port has a similar cure rate and efficiency.However,the use of modified TOT can significantly reduce the incidence of postoperative short-term leg pain,but the long-term efficacy still needs to be further followed-up.

Objective To investigate the association of rs523349(V89L),rs9282858(A49T)and TA repeat polymorphisms in testosterone 5-alpha-reductase Ⅱ(SRD5A2) gene with prostate cancer(PCa) in the population of Yi nationality in Yunnan Province. Methods Sanger sequence detection technique was used to detect rs523349(V89L),rs9282858(A49T)and TA repeat polymorphisms of SRD5A2 gene in 122 subjects with confirmed PCa and 135 age-matched healthy controls in the Yunnan Yi population,then the association of these polymorphisms with prostate cancer was analyzed. Results The AA genotype of rs9282858 site in SRD5A2 gene was not found between the Pca patients and the healthy controls in the Yunnan Yi population. The genotypic and allelic frequency distributions of rs523349 and rs9282858 were not significantly varied between the Pca patients and the controls(P>0.05). But the genotypic and allelic frequency distributions of TA repeat site were significantly varied(P < 0.05). The genotype containing(TA)9 allele was more common in the Pca patients than the healthy controls(P=0.033). Compared with(TA)0 allele subjects,(TA)9 allele subjects had a higher PCa risk(OR=2.181, 95% CI :1.111~4.281,P=0.021). Conclusion The TA repeat polymorphisms of SRD5A2 gene was associated with PCa risk in the Yunnan Yi population,which could be used as a risk factor to screen the high-risk individuals.

Objective To evaluate the clinical efficacy and safety of application of anterograde flexible ureteroscope in the treatment of ureterointestinal anastomotic strictures in patients after Bricker urinary diversion. Methods From March 2009 to July 2012, 6 patients with ureterointestinal anastomotic strictures after Bricker procedure were enrolled in this study. The average age of the patients was (61 ±7) years old. The first clinical presentation was averagely (6.3 ±2.5) months after the Bricker procedure. There were 4 cases with left side strictures and 2 cases with right side ones. The urinary tract ultrasound, CT, KUB+IVP and antegrade urography were carried out to identify the obstructive portion. The mean length of stricture was 0.9cm (0.4~2.5) . First, all patients underwent percutaneous nephrostomy (PCN), then inside incision by Holmium:YAG laser under anterograde flexible ureteroscopy and lithotripsy (with calculi) . The F6 double J ureteral stent was indwelled for 12 weeks. KUB+IVP was performed after removal of double J ureteral stents. Results The mean operative time was (53±8) min. The mean hospital stay was (5.5±2) days. The blood loss was 3~6 mL. The average follow-up was 18 months (6~30) . No recurrence was found in 5 patients. One case had recurrent stricture after the first procedure, which was successfully managed by the flexible ureteroscopy again and replacing double J ureteral stent every 12 months. Conclusion The inside incision by anterograde flexible ureteroscopic Holmium:YAG laser is safe and effective for ureterointestinal anastomotic strictures in patients after Bricker urinary diversion, with less complications.

The comparative experiment of maximin-2 on expression of HLA-DR HLA-ABC by cultured bladder cancer cell lines / 中国药理学通报

AIM To study the boosting effect of Maximin 2 on expression of HLA DR and HLA ABC by cultured bladder cancer cell lines and compare with TNF ??IFN ?. METHODS Cell culture and FCM were used to dectect the effects of Maximin 2,TNF and IFN on the cell growth of three types of bladder cancer cell lines and HLA DR and HLA ABC expression under the IC 50 culture concentration. RESULTS Maximin 2 had show inhibition to cells growth under the small dosage. TNF ??IFN ? also had the effect on restrain all 3 cell lines growth. The expression of HLA DR was not any change in all 3 cell lines after being stimulated by Maximin 2?TNF ? and IFN ?, Maximin 2 and TNF ? can not change HLA ABC expression, IFN ? can up regulate HLA ABC expression. CONCLUSION Maximin 2 show the dose dependent effect on cell growth suppression; The mechanism of antitumor of Maximin 2 seems not relate to the enhanced expression of HLA DR or HLA ABC, TNF ? and IFN ? also not found effect to HLA DR expression. Since IFN ? are able to increase the expression of HLA ABC expression,enhanced recognization and cytotoxity of CTL to bladder cancer cells. It is may be one of the mechanism of antitumor of IFN ?.
