Objective To compare the clinical results between living related and cadaveric donor renal transplantation in the same immunosuppressive regimen and HLA match. Methods Twelve cases of living related donor renal transplantation and 22 cases of cadaveric donor renal transplantation were analyzed retrospectively. The 1-, 3-year patient/graft survival rate, renal function and 1-year acute rejection rate were analyzed respectively.Results No renal function injury and surgical complications were found for living donors during the follow-up period. In living donor group and cadaveric donor group, 1-year acute rejection rate was 16.7 % and 22.7 % respectively (P 0.05). Renal function in living donor group was better than that in cadaveric donor group (P

Objective To investigate the clinical,pathological and histopatholo(g)ical features of primary bladder clear cell carcinoma and discuss the diagnosis and treatment of the disease. Methods The clinical and pathological features of one primary bladder clear cell carcinoma case retrospectively were analyzed,with the combination of reviewing reported literatures. Results The patient came to hospital with the chief complaint of urinary tract symptom and gradually developed gross hematuria.The tumor was located in the left wall of the bladder and was confirmed to be clear cell carcinoma by preoperative biopsy.Partial cysteetomy,ureteroneocystostomy and hysterectomy plus bilateral adnexectomy were performed.The patient received chemotherapy postoperatively and was tumor free 6 months post operatively. Conclusions Primary clear cell carcinoma of the bladder is a rare type of bladder adenocarcinoma.The diagnosis depends on the clinical and pathological study.Surgical operation is effective and the outcome of the disease is better than other non-urothelium carcinoma.

One hundred and twenty five patients, who underwent cystoscopic examination, were randomly divided into two groups: the control group ( n = 62) received conventional cystoscopy, and the treatment group (n = 63) received rociverine 20 mg 1 h before cystoscpy.The pain levels were evaluated using numeric rating scale (NRS) in all patients.The average NRS during examination was 2.1 ±0.9 and 3.6 ± 1.8 in treatment group and control group respectively( P ＜0.01 ).The pain scores in control g roupwere still higher than those in treatment group 15 min and 1 d after procedure ( P ＜ 0.01 or 0.05,respectively).

Objective To explore the clinical significance of second transurethral resection (TUR) in patients with T1 urothelial cell carcinoma of the bladder.Methods The 142 cases with urothelial carcinoma were recruited.All patients underwent transurethral resection of bladder tumor (TURBT) and were diagnosed as stage T1 urothelial carcinoma of the bladder.The 68 of 142 cases underwent second TUR after the initial surgery.Tumor recurrence rate,progression rate and recurrence-free survival were compared.Results There were no statistical differences in age,gender,follow-up time,number of tumors,size of tumors or grade of tumors between patients with and without second TUR.Of the 68 cases that underwent second TUR,25 cases (36.8%) had residual tumor and 6 of them (8.8%) had muscle-invasive bladder cancer.After an average observation for 26.8 months,patients who underwent second TUR showed lower recurrence rate,higher recurrence-free rate and longer recurrence-free survival than patients without second TUR [37.1% vs.58.1%,x2=5.962,P=0.015;41% vs.35.1%,x2=8.502,P=0.004;21 months vs.12 months,U= 1584,P= 0.002].While the progression rate showed no statistical difference between them (14.5% vs.25.7%,x2 =2.570,P=0.109).Conclusions Second TUR provides an effective way to completely excise tumor.Second TUR is beneficial to the decrease of recurrence rate and improvement of recurrence-free survival.However,its effect on tumor progression needs further discussion.

Objective: To preliminarily explore the clinical characteristics and gender difference of patients with variant angina (VA) in China. Methods: A total of 312 patients with spontaneous attack of VA admitted in our hospital from 2003-01 to 2009-12 without stimulation test were retrospectively studied. The clinical features were compared between male and female patients to reveal the similarities and differences of VA by genders. Results: The predilection of VA was in male gender (274/312, 87.8%), the common risk factors including smoking, hypertension and hyperlipidemia; 55/312 (17.6%) patients had allergy history. There were 59/312 (18.9%) patients combining arrhythmia while VA attack; coronary angiography (CAG) found that 155/283 (54.8%) patients were with ifxed coronary stenosis and 22/312 (7.1%) combining coronary myocardial bridge. Nitrates, calcium antagonist and stent implantation may effectively control VA attack. Compared with male, female patients had the lower ratio of smokers (10.5% vs 78.8%),P<0.01, higher ratios of family history of coronary artery disease (CAD) (31.6% vs 11.3%),P<0.01, ventricular tachycardia (13.2% vs 3.6%)P<0.05 and ventricular ifbrillation (7.9% vs 1.8%),P<0.05. Conclusion: VA is a cardiac ischemia caused by coronary artery spasm with high incidence for combining arrhythmia, without in time treatment it may incur myocardial infarction even sudden death. VA patients should receive routine CAG and stent implantation according to the severity of stenosis. Female patients were with less smokers while higher ratios in family history of CAD, ventricular tachycardia and ventricular ifbrillation.

Objective To investigate the clinical presentations, pathologic features, and the di-agnosis and treatment of prostate sarcomatoid carcinoma. Methods Two cases of prostate sarcoma-told carcinoma were analyzed with review of the relevant literature. Case 1, a 51-year-old man com-plained of dysuria and perineal discomfort for 2 months, was admitted because of acute urinary reten-tion. His serum PSA was 2.31 ng/ml. Heterogeneous density of the prostate left lobe and bladder neck involvement was shown on CT scan. Prostate sarcomatoid carcinoma was confirmed by transrec-tal prostate biopsy, and patient accepted radical cystoprostatectomy and ideal conduit followed with lo-cal radiotherapy and hormonal therapy. Case 2 was a 54-year-old male. This ease was admitted with a history of dysuria and intermittent gross hematuria for 1 month. Hypoechoic lesion was found by ul-trasonography,and heterogeneous density of the prostate was shown on CT scan. His serum PSA was 2.61 ng/ml. The prostate biopsy result showed prostate sarcoma. Radical cystoprostatectomy and ide-al conduit was performed on this case. Results The diagnosis of prostate sarcomatoid carcinoma in the 2 cases was confirmed by postoperative pathology. Under microscope, the neoplasm was mainly composed of epithelial and sarcomatoid mesenchymal cells,with a transitional region of these cells. Im-munohistochemical staining showed that the cells were positive for cytokeratin and epithelial membrane antigen. Vimentin was negative in the epithelial cells, but was positive in the majority of sarcomatoid cell. Both patients died of multi-metastasis at 43 and 19 months after surgery respectively. Conclu-sions Sarcomatoid carcinoma of the prostate is extremely rare with a high grade of malignancy,and its prognosis is poor. The diagnosis depends on pathological features and immunohistochemical studies. Radical resection combined with endocrine therapy and radiotherapy is considered to be the most relia-ble treatment so far.

Objective To discuss the techniques and clinical efficacy of laparoscopic partial cystectomy with bilateral pelvic lymphadenectomy for urachal adenocarcinoma. Methods From July 2006 to April 2008, 4 patients with urachal adenocarcinoma were managed by the laparoscopic procedure. Three patients were male, the other one was female, with a median age of 51 (range 42 to 66)years. The mean size of tumors was 3.4(rang 1.9 to 5.4)cm in diameter. Three of them were diagnosed as mucinous adenocarcinoma, the other one was adenocarcinoma. There was 1 patient at stage Ⅱ , and the other three as stage Ⅲ according to Sheldon Stage. Four patients were performed by transperitoneal approach. The boundaries of resection were similar to the open surgery, including resection of the tumor with normal margins, the peritoneum lateral to the two medial unbilical ligaments,the posterior sheath of the rectus muscle and the muscle fibers of the rectus muscle below it, and bilateral pelvic lymphanodes. Results The procedure was successfully in all 4 patients, with a mean operative time of 220(range 150 to 350)min, a mean estimated blood loss of 180 (range 120 to 290)ml.No significant intraoperative or postoperative complications occurred, except for an inferior epigastric artery injury in 1 case. The mean postoperative in-dwelling urinary catheter time was 6 (range 5 to 7)d, and the mean postoperative hospital stay was 6 (range 5 to 8)d. All 36 resected lymph nodes (range 8 to 11) were negative. At a median follow-up of 25(range 15 to 36) months, there was no evidence of recurrent disease by radiologic or cystoscopic evaluation. ConclusionLaparoscopic partial cystectomy and bilateral extended pelvic lymphadenectomy in selected patients with urachal tumors could be a safe, feasible, minimally invasive procedure.

Objective To compare the clinical outcome between open retropubic radical prostatectomy (RRP) and standard laparoscopic radical prostatectomy (SLRP).Methods From January,2008 to December,2014,643 cases of RRP and 161 cases of SLRP were retrospectively reviewed.No significant difference was found in age,body mass index,preoperative prostate specific antigen and pathological results of biopsy between the 2 groups (P ＞ 0.05).The operating time,blood loss,transfusion rate,hospital stay,positive surgical margin rate,urine leakage rate,urethra stricture rate,urinary continence recovery at 6 months and 12 months,2-year biochemical recurrence and median biochemical recurrence of the 2 groups were compared.Results The mean operating time was 131.6 ± 34.5 min in RRP group while 171.3 ±35.1 min in SLRP group (P =0.000).The blood loss was 385 ± 142 ml in RRP group and 194±87 ml in SLRP group (P =0.000),respectively.For the transfusion rate,the RRP group was 3.4％ (22/643) while the SLRP group was 2.5 ％ (4/161),there was no significant difference between the 2 groups (P =0.548).The urine leakage rates were 12.8％ (82/643) in RRP group and 6.2％ (10/161) in SLRP group (P =0.020).The average hospital stay in SLRP group was 6.7 ± 1.5 d,which was significantly shorter than 7.5 ± 1.3 d in RRP group (P =0.000).A pad-free continence was achieved in 68.7％ (442/643) of the cases in RRP group and in 78.9％ (127/161) of the cases in SLRP group at 6 months after surgery (P =0.011).However,there was no significant difference in pad-free continence between the 2 groups at 12 months after surgery (P =0.376).In RRP group,complete continent rate was 94.6％ (608/643),while in SLRP group,it was 96.3％ (155/161).For the positive surgical margin rate,early biochemical recurrence rate and median biochemical recurrence free survival time,no significant difference was found between the 2 groups (P ＞ 0.05).Conclusions Compared to classical RRP,the blood loss during the surgery,urine leakage rate and hospital stay could be significantly reduced in SLRP.Although the patients undergone SLRP could get quicker urinary continence recovery at 6 months after surgery,the urinary continence recovery at 12 months is identical between the 2 groups.RRP and SLRP could achieve nearly the same oncologic outcome.

Objective To investigate the ultrasonic image characteristics of Zenker diverticulum(ZD).Methods The ultrasonographic features were summarized using the analysis confirmed by surgery pathology or X-ray imaging of the ZD in six eases.Results The diverticulum of Zenker located behind the thyroid gland in all the six cases,with five cases to the left and one to the right.The internal hyperechoic foci caused by air was found for all the six cases.The diverticulum wall appeared to be semicircular,narrow-band and acoustic halo low echo with an average thinckness of 0.53 mm.The Doppler sonogram of the six diverticulums showed no vascular signal.Conclusions The ZD had several unique characterisitics for identification by ultrasonic diagnosis,which included hyperechoic foci caused by air,internal changes of echo after drinking water and the special layered structure of the five-layer ZD wall.

ObjectiveTo investigate the diagnosis and the treatment of male interstitial cystitis (IC) to improve the efficiency.MethodsEighteen cases of IC male patients treated from Jan 2010 to Dec 2010 who suffered from suprapnbic pain urinary frequency and urgency were analyzed retrospectively.All these patients were misdiagnosed as category Ⅲ chronic prostatitis.According to the NIDDK diagnostic criteria of IC,Pelvic Pain and Urgency Frequency (PUF) scoring,potassium sensitivity test (PST),and cystoscopy under anaesthesia were used to establish the diagnosis of IC.24 h urinary diary,routine uronoscopy,prostate fluid routine and bacterial culture examination were taken before the treatment of hydrodistention and intravesical instillation of heparin.ResultsAfter the follow-up 12 to 25 months ( average,19 months),the symptoms improved distinctly.The PUF scoring was 19.2 ±4.1 before treatment and 13.6 ±2.4 after treatment respectively ( P ＜ 0.01 ).24 hours' frequency and amount of urination were (7.5 ± 4.3)times and (241.7 ±45.3) ml after treatment compared with (11.5 ±3.9) times and (159.5 ±30.8) ml before treatment ( P ＜ 0.01 ).ConclusionsThe male IC and chronic prostatitis share the same symptoms.They can be differentiated by the IC diagnosis.The treatment of hydrodistention alone with oral tolterodine tartrate sustained release tablets and intravesical instillation of heparin can evidently improve the symptoms of the male IC patients.
