ABSTRACT
<p><b>BACKGROUND</b>Although many midterm oncologic data have been reported for extraperitoneal laparoscopic radical prostatectomy (ELRP) in western countries, few oncologic data of the extraperitoneal procedure was published in China. The aim of the study was to evaluate the oncologic outcomes of patients treated with ELRP in China.</p><p><b>METHODS</b>From January 2005 to March 2010, a total of 152 consecutive patients diagnosed with clinically localized prostate cancer were included in this study and treated with ELRP. The patients were staged according to the TNM (tumor, nodes, metastases) system. Median and mean postoperative follow-up were 28.1 months and 27.0 months, respectively. The patients were retrospectively analyzed for progression-free survival.</p><p><b>RESULTS</b>One hundred and twelve cases (73.7%) were postoperatively diagnosed as pT2 in, and 40 cases (26.3%) as pT3. Positive lymph nodes were shown in 5 patients (3.3%). Gleason score was < 7 in 49 men (32.2%), 7 in 69 men (45.4%), and > 7 in 34 men (22.4%). Positive surgical margins (PSM) were observed in 15 patients (9.9%), which included 32.0% of all pT3a cases and 46.7% of all pT3b cases, respectively. The overall prostate-specific antigen recurrence-free survival rate was 86% in all patients. The recurrence-free survival rates were 91.8% and 62.2% in pT2N0 patients and pT3N0 patients, respectively. Preoperative prostate-specific antigen, surgical margins, tumor stage, and lymph nodal status were identified as independent predictors of biochemical recurrence-free survival using multivariate Cox proportional hazard model.</p><p><b>CONCLUSIONS</b>ELRP is a precise, safe and effective procedure at this particular Chinese institution. The prognostic power of prostate-specific antigen relapse after ELRP is not identical to that described previously with transperitoneal or open retropubic approaches.</p>

Laparoscopic radical prostatectomy is considered the first treatment of choice for local prostate cancer due to its minimal invasion advantage. To further achieve the goal of minimal invasion, single port laparoscopic radical prostatectomy has been developed to minimize the complications associated with puncture tracks. The aim of this study was to illustrate the technique for single port laparoscopic radical prostatectomy and evaluate its efficacy and safety. We reported 8 cases of radical prostatectomy with excellent early outcome carried out in Shanghai Changzheng Hospital from June 2009 to August 2009 using a home-made multiple instrument access port and adding an additional small incision at McBurney point.

Objective:To discuss the management principles and skills for treatment of intractable ureterostenosis under ureteroscope.Methods:Our management experience on 19 patients with intractable ureteral stenosis was retrospectively analyzed.The 19 cases included urological TB-caused multiple ureteral stenosis,oncothlipsis to ureters from intestinal tract or gynecology,restenosis 3 months to 12 years after pelviureteric junction plasty,operative site stenosis after ureterolithotomy. double ureter back flow accompanied by stenosis,ureter imperforation after renal parenchyma lithotomy without placing double"J",ureter imperforation 3 months after extracorporeal shock-wave lithotripsy due to ureterolith,tubal bladder stoma stenosis after renal transplantation,restenosis after tubal bladder stoma due to distal ureterostenosis,and so on.All the patients were treated under ureteroscope.The management methods included:the Wolf 8/9.8 CH12?and Wolf 6/7.6 CH5?ureteroscope was used as a dilator to dilate the stenoses:balloon expanding under ureteroscope was used to dilate the stenoses;the ureter pliers was used to expand the stenoses to different directions;the cold knife was used to open the stenoses;if the diameter of stenoses were smaller than the that of the ureteroscopes,F4.5 or F3 double"J"tubes were inserted guided by a wire under ureteroscope; and 2 or 3 weeks later,a larger tube or two tubes were introduced into the stenoses already dilated partly by the former tube. Results:Ureteroscopic method failed in treating 2 patients in our group and succeeded in treating all the other patients.The outcomes of patient were fine during 9 months to 3 years'follow-up.Conclusion:It is difficult to treat patients with intractable ureterostenoses.With good experience in manipulation of ureteroscope,the flexible application of several techniques according to the different conditions of different patients can guarantee successful treatment in most patients.
