Objective To evaluate the efficacy and safety of tension free vaginal tape obturator technique (TVT-O) in females stress urinary incontinence (SUI).Methods From June 2008 to May 2012,156 cases of female SUI were treated with TVT-O procedure in our hospital.The mean age is 56.3 ±13.9 years.There were 79.5％ patients who suffered simple SUI while 20.5％ patients with SUI and urge urinary incontinence (UUI).The mean follow-up time was 16.5 months.All patient’s ICI-Q-SF scores and I-QOL scores were collected.The efficacy and safety of TVT-O were analyzed.Results The mean operative time was 34 ± 11 minutes and the mean estimated blood loss were 15 ± 9 ml.One hundred and forty-five cases were cured with TVT-O (92.9％) while 8 cases were improved (5.1％).The preoperative and postoperative ICI-Q-SF symptom scores were 8.2 ± 2.1 and 0.5 ± 1.3 while the I-QOL life quality scores were 28.5 ± 10.3 and 69.8 ± 9.9 respectively.There was statistical difference between the preoperative and postoperative scores (P ＜ 0.05 ).No bladder injury was recorded during the procedures.There were two cases whose vaginal walt were injured and repaired intraoperatively.No pelvic hematoma,long-term pain,sling erosion,infection and fistula were found in all cases.Three cases ( 1.9％ ) suffered temporary urinary retention and were cured by two weeks urethral catheterization.Conclusions TVT-O technique seems to be an easy and minimally invasive procedu(r)e with less complication,which supports its safety and reliability in the treatment of female SUI.

Objective To study the characteristics of different papillary renal cell carcinoma (PRCC)subtypes and their prognosis after nephrectomy.Methods Clinical data of 14 PRCC patients(7 males,7 females)with ages ranging from 20-77 in our institute from 2005 to 2011 were retrospectively reviewed.There were 5 tumors in the left kidney and 9 tumors in the right kidney.The average maximum tumor diameter was 3.8(1.6-7.8)cm.Patients presented with gross hematuria(n =3),flank pain(n =3),palpable abdominal mass(n =1)or asymptomatic(n =7).The TNM stages were 8 T1aN0M0,2 T1bN0M0,1 T1aN0M1,1 T2aN0M0,1 T3aN0M0 and 1 T3aN1 M0.Six patients were treated with radical nephrectomy,8 cases were treated with partial nephrectomy.Results There were 6 type Ⅰ and 8 type Ⅱ PRCCs cases.In pathology,type Ⅰ PRCC showed papillae covered by small cells with scanty basophilic cytoplasm,and arranged in a single layer on the papillary basement membrane with low nuclear grade.Type Ⅱ PRCC was composed of cells with higher nuclear grade,abundant eosinophilic cytoplasm,and pseudostratified nuclei on papillary cores.There were 12 well-differentiated cases,2 moderate-differentiated cases and no poorly differentiated case.Follow-up was carried out from 12to 80 months.During the follow-up,1 patient with type Ⅰ PRCC developed multiple lung metastases 26 month after surgery and deteriorated into hepatic and bone metastases at 34 month after surgery.We offered the patient with targeted therapy and the patient was still alive.There was 1 type Ⅱ PRCC patient died with multiple metastases at 42 month after surgery.Others were still alive without local recurrence and metastasis.Conclusions PRCC is not a common subtype of renal cell carcinoma in China.Early stage PRCC patient would achieve good prognosis after treated with nephrectomy.Targeted therapy is a good treatment option for metastatic papillary renal cell carcinoma patients.

Objective To explore the application value of emergency temporal body surface positioning for single drain dual-target thalamic hematoma ventricular drainage in the treatment of thalamic hemorrhage breaking into ventricle with hydrocephalus.Methods A retrospective analysis was conducted on 223 patients with thalamic hemorrhage breaking into the ventricles with hydrocephalus,including a study group of 115 cases who underwent emergency single drain dual-target thalamic hematoma ventricular drainage surgery with temporal body surface positioning,and a control group of 108 cases who underwent emergency ventricular drainage first and then underwent stereotactic thalamic hematoma drainage surgery after the condition stabilized.Compare the differences in postoperative complications and treatment outcomes between two groups of patients,and evaluate the application value of temporal surface positioning for single drain dual-target thalamic hematoma ventricular drainage surgery in the treatment of thalamic hemorrhage breaking into the ventricle with hydrocephalus.Results The postoperative rebleeding rates,hematoma clearance and death were 5.2％,87.5％±7.3％and 13.9％in the study group and 4.7％,90.2％±8.5％and 15.7％in control group,respectively.There was no significant difference between the two groups(P＞0.05).The tube time,postoperative intracranial infection,Shunt dependent hydrocephalus,effective treatment and favorable prognosis of and the control group were(75.5±18.4)h,3.5％,19.1％,53.9％and 51.3％in the study group and(130.8±22.9)h,13.9％,35.1％,38.7％and 38.0％,respectively.The difference between the two groups was statistically significant(P＜0.05).Conclusion Body surface landmark-guided emergency single drain dual-target thalamic hematoma ventricular drainage surgery for the treatment of thalamic hemorrhage breaking into the ventricle with hydrocephalus is safe and reliable,and can improve the patient's prognosis.
