Objective To report our experience of nephron sparing surgery (NSS) with mini-incision approach.Methods Sixty-one mini-incision NSS were analyzed retrospectively from 2005 to 2011 in our department.Demographic and clinical data,complications,histologic and oncologic data were analyzed.There were 35 males and 26 females with average age of 41 years.B ultrasound and CT scan were performed in all cases and MR was performed in 23 cases.CT angiography was performed in 10 cases.Renal cell cancer was diagnosed in 38 cases,angiomyolipoma in 14 cases,complicated renal cyst or duplicated kidney in 6 cases and no definite diagnosis in 3 cases.All the lesions were single with 21 in the right side and 40 in the left side.The average diameter of the lesions was 3.2 (2.3-8.8) cm.The mini-flank supra-12th rib incision was performed in all cases.The renal artery was clamped with bulldog clamp,all transected blood vessels on the renal incisal surface were sutured with 3-0 Vicryl sutures,and collecting system was closed with continuous' 3-0 Vicryl suture.Results The average length of incision was 8.1 (6.5-11.0) cm.The average operative time was 93 (70-140) min.The average warm ischemia time was 19 (12-32) min.The average blood loss was 72 (20-300) ml and the average hospital stay was 6 (5-15) d.The delayed hemorrhage was occurred in 1 patient who was treated with conservative treatment.Clear cell carcinoma was found in 28 cases,chromophobe carcinoma was found in 6 cases,papillary carcinoma was found in 5 cases,angiomyolipoma was found in 16 cases,complicated cyst was found in 3 cases and renal duplication was found in 3 cases.Fortyfive patients were followed up from 28 to 82 months with no delayed complication and no recurrence or metastasis in 35 malignant cases.Conclusions The approach of mini-incision NSS can duplicate the procedure of traditional open NSS.This approach can also couple the benefits of both laparoscopic and open NSS techniques with a smaller incision which can be used to remove the specimen.

Objective To explore the influence of renal allograft donor's and recipient’s SNP of recipient cytokine and cytokine receptor on the infection after renal transplantation and to provide some useful information for preventing and managing infection.Methods 129 cases of cadaveric renal allograft recipients were divided into infection group and no infection group. The distribution of 21 polymorphisms in cytokines and cytokine receptors gene were compared between two groups by oligonucleotide array. Previous positive gene polymorphisms were compared between infection group and no infection group. With the help of SPSS 11.5 software, association was assessed using Krusakal Wallis test where appropriate.Results The frequency of gene distribution was significantly different between the infection group and the no infection group as follows: the genotype IL-6R (-183G/A, GG), IL-10 (-824C/T, -597C/A), TNF-? (-308GG, G/A), and the allele IL-10R1 (1112G/A), IL-6R (-183G/A), IL-4R(1902A/G), TNF-? (-308G/A), TGF-?_1 (+869T/C) respectively.Conclusion The susceptibility of infection after renal transplantation may be predicted by the SNP of recipient cytokine and cytokine receptors such as these genotypes IL-6R(-183GG), IL-10(-824CT, -597CA), TNF-?(-308GG), and the allele IL-4R(1902A).

Objective To study the surgical treatment of the primary retroperitioneal sarcoma(RPS). Methods The treatment and prognosis of 63 patients with primary retroperitoneal sarcomas (liposarcomas and leiomyosarcomas) from Jan 1992 to Dec 2000 were analyzed retrospectively. Results The rate of complete tumor resection was 88.2%, and concomitant resection of involved adjacent organs was 21.6%. There was no operation death. The median survival time(MST) in liposarcomas that for was 36.5months, and leiomyosarcomas was 27.6 months. The MST in highly differentiated tumor was 34.7 months,and that of intermiade and low differtiated tumors was 18.1months(P

Objective To assess the clinical efficacy of patient controlled intravenous analgesia (PCIA) with mixture of fentanyl and droperidol for post-prostatectomy pain. Methods 104 patients undergone prostatectomy were randomly divided into two groups. In group A, the patients received PCIA.In group B, they received routine analgesia.The pain scores of visual analogue pain scale (VAS) and control of bladder spasm were recorded at various time postoperatively, and the time of continuous infusion of bladder, the time of indwelling catheter and the mean hospitalization time were also recorded. Results Compared with those of group B,the VAS,continuous time and ratio of bladder spasm decreased markedly in group A ( P

Objective To evaluate the clinical efficacy of percutaneous nephrolithotomy (PNL) in combination with pneumatic and ultrasonic lithotripsy in the treatment of complex renal calculi. Methods Under general anesthesia,an ureteral stent was placed into the patient by cystoscopy. With the prone position,percutaneous access was established by inserting an access needle into the intended calix under the guidance of ultrasonography or fluoroscopy. Afterwards,combined pneumatic and ultrasonic probes were used by nephroscopy for lithotripsy. Results A single tract was used in 137 patients,while two or three tracts were created in the other patients (11 and 2 respectively). One-step procedure to remove the stones was achieved in 119 patients,while a second intervention was performed in 27,and three procedures was carried out in 4. The mean time of the operations were (88?34) min. After the operation,one patient developed infectious shock,and then was cured by anti-shock therapy;two patients showed secondary hemorrhage in two weeks postoperation,and was cured by conservative therapy. In this series,the rate of stone clearance was 84.7% (127/150);23 cases had residual stones,10 of them received ESWL (the stone was removed completely in 7 of the 10 cases),and the other 13 were treated by oral medicines. Six months after the operation,follow-up examination showed a stone-free rate of 89.3% (134/150). Conclusion Combination of ultrasonic and pneumatic intracorporeal lithotripsy is effective and safe for complex renal calculi,which is intractable by open surgery.

With building up a clinical modification system model by upgrading the standard disease classification system architecture,to collect those huge amount of diagnosis names and codes in use,based on the model to screen and coordinate the relation of them,the tenth revision of the International Classification of Disease Clinical Modification of Beijing is implemented.This standard has been successfully applied for two years in all those secondary and above level hospitals in Beijing.It could well support the work of deploying Diagnosis Related Groups in Beijing and support not only those traditional applications of disease classification but also those new and advance requirements of information processing.

Objective To assess the efficacy and safety of tolterodine on late-onset overactive bladder symptoms after prostate brachytherapy due to prostate carcinoma.Methods Twenty-six prostate cancer patients diagnosed by biopsy,who underwent prostate brachytherapy using iodine-125,were recrui(t)ed in this trial.All cascs complained of overactive bladder symptoms 6 months postoperatively.The 26 patients were divided into 2 groups:14 men in tolterodine group (TR group) who were given tolterodine 2 mg twice a day; 12 men in tamsulosin group (TS group) who were given tamsulosin 0.2 mg once a day.Efficacy was assessed by changes in IPSS,OABSS and nighttime voiding at 2 weeks and 4 weeks after medical treatment respectively.Safety was assessed by postvoid residual (PVR) and acute urinary retention (AUR),dry mouth,constipation and tachycardia at the fourth week after medical treatment.Results The age,tumor staging,GS,PSA,initial prostate volume,IPSS,OABSS,nighttime voiding,iodine-125 seeds implanted and needles punctured of both groups were comparable.IPSS,OABSS and nighttime voiding were significantly improved in TR group after 2 weeks of medical treatment and the above parameters were significantly improved than TS group (14.4 vs 18.3,5.9 vs8.4,1.4 vs2.5).OAB symptoms of TR group were also significantly improved than TS group after 4 weeks of therapy.There were no significant differences of PVR and AUR,dry mouth,constipation and tachycardia between both groups.Conclusions Tolterodine is effective and safe in treating late-onset OAB symptoms after prostate brachytherapy,although the occurence of dry mouth and tachycardia might be increased.
