Objective To evaluate the efficacy and safety of the TVT-Secur procedure for female stress urinary incontinence (SUI). Methods Analyze retrospectively the preoperative, intraoperative and postoperative complications and follow-up data of 27 SUI patients from October 2008 to May 2010. 20 cases were simple SUI, and 7 cases were mixed SUI. The average age was 56.1 ± 10.7 years (range, 35-77), the average parity was 2.8-±- 1.4 (range, 1-6), the average body mass index was 25.6±2.5, and the average course of the disease was 6.8±7.2 yeas (range, 1-30). Two cases had past history of pelvic surgery without any anti-incontinence surgery. Mashall-marchett test was positive in all patients, with an average abdominal leak point pressure (ALPP) of 60.9±27.5 cm H2O (range, 27- 120 cm H2O). The mean International Consultation on Incontinence-Short Form (ICIQ-SF) score was 11.2 ± 1.8 (range, 7- 14) before surgery. Results 27 patients underwent TVT-Secur procedure, of which 19 cases underwent "U" procedure, and 8 cases underwent "H" procedure. The mean operation time was 15.3±1.4min (range, 13- 19 min). There were no intraoperative bladder or urethral injury, and no obturator vessel or nerve damage. The blood loss was 10 to 50 ml, and the maximum urinary flow rate was 25. 4±13. 1 ml (range, 4-50 ml). Three eases had mild dysuria(11. 1%), and 3 cases had wound effusion(11. 1%). Followed up for 12. 6 ±6. 7 months (range, 3-21 months). 10 cases complained of bladder overactivity symptoms such as frequency, urgency, and urge incontinence, and no case had vaginal erosion. Therapeutic efficacy: 15 cases were cured (56%), 8 cases were improved (30%), and 4 cases were ineffective (15%). Conclusions TVT-Secur procedure is a simple, safe and minimally invasive surgery, while the cure rate is low. The long-term efficacy needs great amount of clinical data and long-term follow-up to prove.

Objective To study the clinical efficacy and operative skill of multi-endoscopic technique in treatment of post-traumatic urethrostenosis in male patients.Methods A retrospective analysis was done on clinical data of 47 male patients with post-traumatic urethrostenosis treated with direct visional incision urethrotomy combined with transurethral resection of scar tissue and ureteroscopic incision.There were 29 patients with anterior urethral strictures and 18 with posterior urethral strictures.Results Of all,43 patients underwent successful endoscopic surgeries at the first time but one underwent secondary surgery because of unsuccessful endoscopic incision.These patients achieved satisfactory results without urinary incontinence,fistula or reoperation.The left three patients underwent open surgeries because of unsuccessful endoscopic incision,in which one patient could micturate at maximal flow rate of 9-12 ml/s,without therapeutic urethral dilation,one could micturate under regular therapeutic dilation and the other one could not micturate.Conclusions With the advantages of safety,high success rate and good long-term efficiency,multi-endoscopic technique can be used as an initial treatment for male patients with post-traumatic urethrostenosis and is worthy to be popularized.

Objective To assess the clinical value of intravesical prostatic protrusion (IPP) measured by transabdominal uhrasonography in judgement of benign prostatic obstruction (BPO). Methods According to pressure-flow study, 109 patients with benign prostatic hyperplasia were di-vided into 3 groups (non-obstruction, equivocal obstruction and obstruction). IPP was measured by transabdominal ultrasonography in all patients. The difference of IPP between different groups was studied and the correlation between IPP and the parameters reflecting BPO was analyzed. Results IPP value of the non-obstruction group, equivocal obstruction group and obstruction group was 2.7 ±1.2 mm, 2.9±1.4 mm and 15.4±6.5 mm. There was significant difference in IPP between the non-obstruction group, equivocal obstruction group and obstruction group (P<0.01). IPP was correlated with the parameters including Pdet. Qbeg, Pdet. Qmax, Pdet. Qend, Qmax and A-G number, Spearman's ratio was 0. 628, 0. 714, 0. 591, -0. 450 and 0. 729(P<0.01), respectively. The sensi-tivity and specificity of judging BPO were 89.9% and 97.5% if the cut-off was IPP≥10 mm. Con-clasion IPP measured by transabdominal ultrasonography could be a convenient and accurate method in diagnosis of BPO.

Objective:To report two cases of post-transplantation lymphoproliferative disorders (PTLD) after kidney transplantation in children and review the literature, and to improve clinicians' understanding of PTLD in children.Methods:The clinical data of two children with PTLD admitted to the Children's Hospital of Fudan University were collected and analyzed. The PTLD-related literature of PubMed, Embase, Web of Science, Scopus, Cochrane Library, Wanfang, CNKI, Weipu Database and China Biomedical Literature Service System from the establishment of the database to January 2020 were collected for literature review. Multivariate logistic regression analysis method was used to analyze the influencing factors of prognostic in children with PTLD.Results:Both of the patients had negative Epstein-Barr virus (EBV) and Cytomegalovirus (CMV) before transplantation and anti-thymocyte immunoglobulin (ATG) were induced during transplantation. PTLD in case 1 and case 2 was diagnosed at 3 and 12 months after transplantation, respectively, with positive EBV and CMV serological reaction. The pathological diagnosis was monomorphic PTLD in case 1 and the case 2 was clinically considered as non-hodgkin lymphoma. They all received thrapies of immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. PTLD was relieved and graft function was normal in 2 cases, while case 1 died two and half years after transplantation due to intracranial fungal infection. According to the analysis of 56 children (including 2 cases in this study) with PTLD from the literature review, the median time of PTLD from transplantation was 41.8 months. The initial involved organs were digestive tract [17 cases (30.4%)], respiratory system [8 cases (14.3%)], nervous system [7 cases (12.5%)] and pharyngeal lymph ring [7 cases (12.5%)], respectively. The main pathologic type of PTLD was monomorphic [34 cases (60.8%)]. Fifty-six cases were all positive in EBV serological reaction when PTLD was diagnosed. The treatment included immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. Forty-eight cases of PTLD were relieved, while 8 cases lost graft function. Eleven cases died, including 3 cases due to infection and the other 8 cases due to PTLD. Multivariate logistic regression showed that monomorphic PTLD was a risk factor of death for PTLD children ( OR=21.616, 95% CI 1.007-464.107, P=0.049). Conclusions:PTLD in children with kidney transplantation is mostly associated with EBV infection, and the clinical manifestations are diverse. Monomorphic PTLD has a poor prognosis and high mortality.

Objective To investigate nursing measures for dacryagogatresia and diabetes patients treated with trepanation using the lacrimal endoscopy .Methods Eighty dacryagogatresia and diabetes patients who were admitted to the Department of Ophthalmology of the Second Affiliated Hospital of Nanjing Medical University from January 2013 to February 2015 were divided into the control group ( n=40 ) and the intervention group (n=40) and were treated with trepanation using the lacrimal endoscopy .The patients in the control group accepted normal nursing , while the patients in the intervention group accepted systemically comprehensive nursing based on normal nursing .The effective rate of the operation and the incidence of complications were compared between the patients in the two groups .Results The effective rate in the intervention group was significantly higher than that in the control group (P<0.05).The incidence of complications in the intervention group was significantly lower than that in the control group (P<0.05).Conclusions Effective preoperative, intraoperative and postoperative nursing measures greatly improve the effect of surgical treatments in dacryagogatresia and diabetes patients and reduce or avoid operation complications .
