Objective to investigate the feasibility and outcomes of different surgical treatments for adrenal metastasis after previous radical ne-phrectomy for patients with renal cell carcinoma. Methods A total of 18 adrenal solitary metastasis of renal cell carcinoma were identified from da-tabase of two institutions between 2003 and 2013. Clinical and pathologic data were collected and analyzed. Results Of 9 patients who had ipsilater-al metastasis of the renal tumor,the estimated blood loss were obviously fewer in the transperitoneal LA group. Of 9 cases who had contralateral me-tastasis of the renal tumor,the fasting time[(1.4±0.8)h vs(4.0±1.4)h,P = 0.036]and length of hospital stay[(4.5±1.2)d vs(7.0±4.5)d,P =0.041]were obviously fewer in the retroperitoneal LA group. the averages of the fasting time and length of hospital stay in the retroperitoneal LA group were obviously smaller than in the transperitoneal LA group. Conclusion LA for treatment of renal cell carcinoma metastasis is technically feasible in selected patients. transperitoneal and retroperitoneal LA can be respectively recommended as an appropriate approach for isolated adrenal metastases of ipsilateral and contralateral renal cell carcinoma after nephrectomy.

Objective To evaluate the impact factors on weight and proportion of prostate tissue resected by transurethral resection of prostate (TURP) in patients with benign prostatic hyperplasia (BPH). Methods The patients undergoing TURP from January 2007 to June 2009 and diagnosed as BPH according to postoperative pathological results were enrolled in this study. The prostate volume measured by transrectal ultrasound (TRUS), prostate specific antigen (PSA), maximum flow rate (MFR), residual urine volume and body mass index (BMI) were measured and calculated. The prostate tissue collected at resection was weighed, and the proportion of the prostate resected was the percentage of the pre-operative estimated weight. Results For the 458 patients with the average age of 69.5 years, average BMI was 24. 3 kg/m2 , PSA 6. 1 μg/ml, prostate volume 85.5 ml, MFR 8. 4ml/s, residual urine volume 31.8 ml, resected prostate weight 32.9 g, proportion of resection 37. 6%Prostate volume and BMI were positively related with resected prostate weight. BMI was positively related with proportion of prostate resection. There was no linear correlation between prostate volume and resected proportion. But there was significant difference in resected proportion between patients with prostate volume more than and less than 40 ml. Finasteride had no influence on the weight and resected proportion. Conclusions Prostate volume, PSA and BMI are correlated with weight and proportion of prostate tissue resected by TURP. Finasteride has no influence on the resected weight and proportion.

Objective To study the initial application of 3.0T high field intensity intraoperative magnetic resonance(iMR)for cranial tumors.Methods Forty-three patients with cranial tumors including 23 glioma cases,12 pituitary tumor cases,3 brain stem cavernous hemangioma cases,2 meningioma cases,2metastatic tumor cases,1 neurilemmoma case,received operation examined with GE Signa HDX 3.0T iMR system.The operation process and influence of iMR were reviewed.Results In 43 patients,average iMR examination was 1.3(1-3)times.In 16 patients the first iMR examination revealed tumor remnants,and in 13 of them continued surgical interventions and complete resection.The rate of complete resection was increased from 63％(27/43)to 93％(40/43).No complications related to iMR occurred.Conclusion 3.0T high field intensity iMR can provide accurate positioning and real-time navigation for the surgery,increase the rate of complete resection,improve the accuracy and safety of cranial tumor resection,and decrease complications.

Objective To describe the distribution of positive lymph nodes of muscle invasive bladder cancer, and explore the relationship between positive nodes and pathological characters. Methods Pathological data from 208 consecutive cases of muscle invasive bladder cancer were collect-ed and reviewed. The correlation of tumor grade, tumor stage and lymph nodes status was analyzed. The locations and numbers of positive nodes were recorded and compared according to the specific grade or stage. Results There were 153 cases (73.6%)of G_3 tumor and 55 cases(26.4%) of G_2 tumor and none G_1 (0%)in this cohort. The case number from pT1 to pT4 was 59(28. 4%)、58 (27.8%)、48(23.0%)and 43(20.6%), respectively. The tumor grade was positively correlated with tumor stage in this cohort (r=0. 392, P=0. 000). 153 cases had been taken lymph node dissection. There was more node positive cases in pT_3 and pT_4 than that in T_1 (P=0. 001 ,P=0. 000), as well as pT_4 compared with pT_2 (P= 0. 012). The data showed that most of the positive nodes were located within the pelvic region. There was only 1 case and 1 node positive for G_1/G_2 tumor with 24.84% of node positive cases for G_3. The positive nodes involved from pelvic to proximal artery while the stage increased. Conclusions There is less chance for low grade (G_1/G_2) bladder cancer to be node posi-tive compared with G_3 ones. It is necessary to take a extensive lymphadenectomy for the patients with stage more than T_2.

OBJECTIVE To study the diagnosis and management of epistaxis caused by traumatic pseudoaneurysm.METHODS The clinical data of 16 cases with epistaxis caused by traumatic pseudoaneurysm were retrospectively studied.There were 12 males and 4 females.Their ages ranged from 16 to 41 years with an average of 25.4 years.RESULTS All the patients were cured via digital subtraction angiogrophy(DSA) and embolization except one died.The time between the hospitalization and the DSA examinat ion was 3 to15 days.Interestingly,every patient had received anterior and posterior nasal packing one to 5 times.CONCLUSION If the anterior and posterior nasal packing were not effective to the patients with repeated and vast nasal bleeding,who had trauma history before nasal bleeding,the DSA examination should be carried out immediately to identify whether the pseudoaneurysm exists.

Objective To explore the clinicopathological characteristics of non-muscle-invasive bladder cancer patients association with chronic kidney disease (CKD).Methods Between Jan 2009 and Dec 2010,536 patients (390 males and 146 females with mean age of 63 years) underwent surgical treatment at our institute for pathologically proven non-muscle-invasive bladder cancer.The clinical and pathological data of these patients were reviewed,and the relationships of these factors and CKD were analyzed.Presence of CKD was confirmed in patients with estimated glomerular filtration rate (eGFR)＜ 60ml/(min · 1.73 m2)calculated using the Modification of Diet in Renal Disease Study equation.Results Of the 536 consecutive cases,57 patients (10.6％) had CKD.Compared to the patients without CKD,there were more females and older patients in the patients with CKD (52.6％ vs 24.2％ and 69 years vs 62 years,both P ＜ 0.05).The patients with CKD proned to have multiple bladder tumor (71.9％ vs 50.9％,P ＜ 0.05) and synchronous upper urinary tract urothelial carcinoma (7.0％ vs 2.3％,P ＜0.05).The history of bladder cancer and upper urinary tract urothelial carcinoma were also predominated in these patients (43.9％ vs 29.0％ and 40.4％ vs 6.5％,both P ＜ 0.05).ConclusionConcurrent CKD in non-muscle-invasive bladder cancer patients is associated with greater risk of multiple tumors in urinary tract,particularly in female patients.

OBJECTIVETo study the clinicopathological characteristics of papillary cystadenoma of the epididymis.

METHODSUsing routine pathology and immunohistochemistry, we observed the surgically obtained samples from 2 cases of papillary cystadenoma of the epididymis, analyzed their pathological features and clinical presentations, and reviewed the related literature.

RESULTSThe 2 patients were both adult males. The tumors typically manifested as painless swelling in the epididymis, with occasionally dull pain and tenesmus in 1 of the cases. Pathologically, the lesions exhibited three morphological features, i. e., dilated ducts and small cysts surrounded by fibrous connective tissue, adenoid papillary hyperplasia into the cysts embraced by fibrovascular stroma, and acidophil substance present in the cysts. Immunohistochemistry showed that the tumors were strongly positive for CK8/18, CK7, and EMA, but negative for CK20, CEA, MC, Calretenin, P53, P63, SMA, VHL, and CD10, with the positive rate of Ki-67 <1%. Follow-up visits revealed good prognosis in both cases.

CONCLUSIONPapillary cystadenoma of the epididymis is a rare benign tumor in the male urogenital system, which may be accompanied by the VHL syndrome. Surgery is the first choice for its treatment.
