Objective To study the diagnosis and surgical treatment of adrenal cavernous hemangi -oma. Methods The data of one case with adrenal cavernous hemangioma was retrospectively reviewed .A 62-year-old female patient admitted in out hospital on 18th June, 2013 due to the paroxysmal hypertension for 10 years and finding the left adrenal mass for 2 months.Her highest blood pressure was 175/55 mmHg and the response for the drug treatment was poor .In recent 6 months, her blood pressure was unstable .Ab-dominal ultrasound showed a hypoechoic mass in left adrenal .Enhanced CT examination showed an irregular mass in the left adrenal gland , with the size of 4.5 cm ×2.5 cm ×3.9 cm,peripherally enhanced in arterial phase , contrast agent filling in portal venous phase , and high density in delay phase .Abdominal MR exami-nation showed a mass before abdominal aortic , with clear and smooth edge .The mass showed low signal in T1WI phase and high signal in T 2WI phase, which was considered as pheochromocytoma .24h urinary cate-cholamines showed that norepinephrine was 103.0 nmol, epinephrine was 9.8 nmol and dopamine was 18.9 nmol.Octreotide (99Tcm-TOC) showed slight high expression of somatostatin receptor .Preoperative diagnosis was left pheochromocytoma . Results After the preoperative medical preparation of phenoxybenzamine for 3 weeks, her blood pressure was maintained at 120-132/50-70 mmHg, with stuffy nose, warm hand and foot, and the weight gain of about 1 kg.The patient was undergone laparoscopic resection of left adrenal tumor under general anesthesia on June 24, 2013.The postoperative blood pressure returned to normal .And the left adrenal pathology was cavernous hemangioma .Following up for 5 months, the patient had normal blood pressure without the tumor recurrence . Conclusions The adrenal cavernous hemangioma is extreme-ly rare with high rate of misdiagnosis .For adrenal tumor with typical hemangioma imaging , the diagnosis of cavernous hemangioma should be considered .For tumors larger than 6 cm, surgery is recommended .The first choice of operative approach is laparoscopic resection of adrenal tumor , and normal adrenal tissue should be retained as far as possible.

Objective To analyze the recovery of the renal function in the severe hydronephrosis children after percutaneous nephrostomy.Methods 50 cases of uretero-pelvic junction obstruction (UPJO) children were retrospectively studied from January 2013 to January 2016.There were 25 boys and 25 girls,and the mean age was 3.0 years (ranged from 2 months to 9 years and 7 months).The children were taken the percutaneous nephrostomy in the first stage and pyeloplasty or nephrectomy in the second stage according to the recovery of renal function.Split renal function,urine osmotic pressure,urine pH and urine β2-microglobulin (β32-MG) were compared between pre-operation and post-operation.The recovery of the renal function after the operation were evaluated by the single photon emission computed tomography (SPECT) and superb micro-vascular imaging (SMI) to analysis the feasibility of the pyeloplasty surgery in the severe hydronephrosis children.Result The postoperative renal function of 49 patients in the group recovered after percutaneous nephrostomy,only one child showed unrecoverable.After the first stage management,the renal cortical thickness [(5.9 ± 1.0)mm vs.(2.9 ± 0.9) mm,P =0.03],the separate renal function mmo]/L vs.(126.5 ± 100.5) mmol/L,P ＜ 0.001] were significantly improved compared with preoperation,andRI [(0.72 ±0.03) vs.(0.79 ±0.04),P=0.021],urine pH [(6.18±0.21) vs.(7.38 ± 0.32),P =0.039] and urine β2-MG [(562.16 ± 49.78) mg/L vs.(954.28 ± 69.45) mg/L,P ＜0.001] significantly reduced.Conclusions The renal function of the severe hydronephrosis children could be recoverable after the surgery of the percutaneous nephrostomy and pyeloplasty.Most children's kidneys suffered the severe hydronephrosis could be spared by surgery.SMI technology could provide reliable quantitative basis to evaluate renal function.

Objective To evaluate the efficacy and safety of the modified docetaxel plus prednisone scheme for the metastatic castration resistant prostate cancer patients who got poor tolerance to chemotherapy.Method The clinical data of 50 metastatic castration resistant prostate cancer who received docetaxel + prednisone chemotherapy from March 2010 to October 2015 were analyzed retrospectively.23 cases received the modified DP regimen (modified group),27 cases received the standard DP regimen (standard group).The median age of the modified group and the standard group were 69 years (47-80 years) and 63 years (52-77 years) (P =0.005).There were 19 and 24 cases with pain in modified group and standard group respectively;10 and 19 cases with lymph node metastasis respectively;3 and 4 cases of visceral metastasis respectively;all of the 50 patients were complicated with bone metastasis.For the pathological Gleason score,there were 7 cases scored ≤7 points,13 cases scored ≥ 8 points and 3 cases unscored in the modified group;7 cases scored ≤7 points,15 cases scored ≥8 points and 5 cases unscored in standard group.There was no significant difference of the pain,metastasis,and Gleason score between the two groups (P ＞ 0.05).Progression free survival (PFS),overall survival (OS)and adverse events were analyzed using Kaplan-Meier curves,and the differences were assessed using the log-rank test.Results In the modified group and standard group,the median follow-up times were 11.0 months and 14.0 months respectively,the median chemotherapy cycles were 4.5 cycles and 5.0 cycles respectively;OS were 18.0 months and 27.5 months respectively (P =0.746).The PFS of the two groups were 6.0 months and 5.2 months,respectively (P =0.822).The PSA response were 13 cases and 17 cases in the modified group and standard group respectively (P =0.615),and the pain response were 8 cases and 7 cases (P =0.927),grade 3 to 4 adverse events were 3 cases and 14 cases (P =0.003).The main adverse events were blood toxicity,neutrophils,gastrointestinal reaction,edema,fatigue and oral mucositis etc.Conclusions Compared with the standard DP scheme,the modified DP scheme had no significant difference in OS,PFS,pain response rate and PSA response rate,while the incidence of grade 3 to 4 adverse events was significantly reduced.Modified DP scheme may be a better choice for patients with metastatic castration resistant prostate cancer who get poor tolerance to chemotherapy.

Objective To compare the outcomes of Yang-Monti channels and appendix in the practice of catheterizable continent urinary conduits.Methods Retrospective analyses were conducted in 27 cases with neurogenic bladder from July 2009 to December 2015,including 8 male and 19 female patients whose average age at surgery was 7.6 years old (range:1.5-16 years).The average bladder volume is (203.8 ± 126.0) ml.The bladder compliance values of 24 cases are lower than 20 ml/cm H2O.Seventeen cases had urinary infection combined with fever before surgery,while 6 cases had stress urinary incontinence and 17 cases had dysuria.Seven cases including 2 male patients underwent urinary diversion with YangMonti channels (YM group) and the average age at surgery for patients was 6.7 years old (range:4-16years).Twenty cases including 6 male patients underwent urinary diversion with appendix (AP group) and the average age at surgery for patients was 8.0 years old(range:1.5-14 years).The 3-day urinary diaries were collected in all cases including their records of average catheterization interval,average catheterization volume,stoma stenosis and stoma leakage.The data between the two groups was compared and the statistical analysis was performed.Results Of the 7 patients undergoing Yang-Monti channels,2 cases underwent open surgery and 5 cases underwent laparoscopic surgery in which 2 cases transferred to open surgery.The stoma stenosis occurred in 1 case and the stoma leakage occurred in 1 case.The average catheterization volumc is (239.3 ± 76.2) ml and the average catheterization interval is (2.8 ± 0.9) h.Six patients in the group were followed up less than 3 years,of which the average catheterization interval is (2.6 ± 0.8) h.Of the 20 patients undergoing appendix channels,3 cases underwent open surgery and 17 cases underwent laparoscopic surgery in which 1 case transferred to open surgery.The stoma stenosis occurred in 1 case and the stoma leakage occurred in 2 cases.The average catheterization Volumee is (257.0 ± 67.4) ml and the average catheterization interval is (3.9 ± 0.9)h.Six patients in the group were followed up less than 3 years,of which the average catheterization interval is(3.5 ± 1.0) h.There was no difference in stoma stenosis and stoma leakage and average catheterization volume between the two groups (P ＞ 0.05).There was no difference in average catheterization interval between the patients of two groups who were followed up less than 3 years (P ＞ 0.05).Conclusions Yang-Monti conduits are durable and reliable,which was similar with appendix conduits.

Objective To evaluate the effectiveness and security of Botulinum toxin type A (BTX-A) in treating interstitial cystitis /bladder pain syndrome,and also the effect of different site injection.Methods Sixty-nine consecutive BPS/IC patients from October 2011 to February 2016 were divided into three groups randomly,including control group (group A) and treatment group (group B and group C).There were 5 males and 64 females,with age from 23 to 66 years old (average 44.5 years old).Twentythree patients (1 male and 22 females,aged from 23 to 69 years old,with mean age of 44.6 years old) in control group (group A) underwent hydrodistention.Twenty-four patients (2 males and 22 females,aged from 27 to 65 years old,with mean age of 42.8 years old) in group B underwent BTX-A detrusor combined triangle injection plus hydrodistention.Twenty-two patients (2 males and 20 females,aged from 30 to 68 years old,with mean age of 44.3 years old) in group C underwent BTX-A triangle injection alone plus hydrodistention.The parameters such as daytime frequency,nocturia,visual analogue scale/score (VAS),functional cystemetric volume (FCV),post-void residual volume (PVR),QOL score,maximal bladder capacity (MBC),interstitial cystitis symtom index (ICSI),interstitial cystitisproblem index (ICPI),Qmax,and Hamilton anxiey scale (HAMA) score between pre-treatment and 1,3,6 and 9 months after therapy in the three groups were compared.Results There were no serious complications observed in the three groups.All parameters 1 month after therapy were obviously superior to that of pretreatment.The efficacy in control group decreased significantly 3 months after treatment except nocturia (3.0 vs.5.0),daytime frequency(7.0 vs.14.0)and Q (14.0 ml/s vs.13.0 ml/s).However,all parameters in research groups except PVR were still obviously superior to pretherapy.The parameters except Q and nocturia in group B had statistically significant difference from contemporaneous group A (all P ＜ 0.05).However,the parameters except Q nocturia and somatic anxiety score in group C had statistically significant difference from contemporaneous group A (all P ＜ 0.05).VAS (2.0 vs.3.0) and somatic anxiety score (6.0 vs.10.0) in group B were superior to group C (all P ＜ 0.05).When it came to 6 months after therapy,urinary frequence and urgency and pain symptoms were the same to pretherapy and all parameters had no statistically significant difference between pretherapy and after therapy in group A(all P ＞ 0.05).But all parameters except PVR in research group was still superior to pretherapy.the parameters except PVR,Q and QOL in group B had statistically significant difference from contemporaneous group A (all P ＜ 0.05).However,The parameters except PVR,Q MBC,ICSI and QOL in group C had statistically significant difference from contemporaneous group A (all P ＜ 0.05).Meanwhile,efficacy in group B was better than group C in term of ICPI (6.0 vs.8.0) and somatic anxiety score (7.0 vs.10.0) (all P ＜ 0.05).The efficacy decreased significantly 9 months after treatment in both group B and C,with no statistically significant difference compared with that of pretreatment.ICSI(10.0 vs.13.0),ICPI(9.0 vs.13.0),QOL(5.0 vs.6.0)in group B,and QOL(5.0 vs.6.0)in group C had statistically significant difference compared with the contemporary parameters in group A.ICSI(10.0 vs.12.0),MBC(285.0 ml vs.237.5 ml) in group B was better than that in group C (P ＜ 0.05).Conclusions Symptoms in IC/BPS patients can be alleviated significantly by detrusor BTX-A injection plus hydrodistention.Quality of life can be improved remarkably and HAMA scores can be reduced significantly after treatment.Thus,it's an effective therapeutic mnethod for IC/BPS,and detrusor combined triangle injection can provide a better effect than single triangle injection.

Objective To explore the factors imfluencing the prognosis of patients with renal cell carcinoma after laparoscopic partial nephrectomy.Methods Clinical data from 593 renal cell carcinoma patients underwent laparoscopic partial nephrectomy in our institution from December 2010 to December 2015 were retrospectively collected..Tbere were 396 males and 197 females,aged 35 to 72 years old(mean 55.4 years).There were 181 cases of smoking history,206 cases of hypertension and 105 cases of diabetes.Before operation,98 cases of liver function were damaged and 122 cases were anemia.There were 521 cases with PLT ＜ 450 × 109/L,72 cases PLT≥ 450 × 109/L.Thc tumor of 292 cases on the left and 301 cases on the right.The Kaplan-Meier method log-rank test was used for survival analysis.Univariate analysis and factors which were significantly associated with survival in the univariate analysis were conducted into the multivariate analysis with Cox proportional hazards model.Results The operative time was 88.0-120.6 min,mean 104.3 min,the blood loss during operation was 47.2-157.8 ml,mean 102.5 ml. Pathological tumor stage revealed that 398 cases were T1 and 195 cases were T2 . Fuhrman classification revealed that 29 cases were grade Ⅰ,411 cases were grade Ⅱ,150 cases grade Ⅲ,3 cases grade Ⅳ . The median follow-up time was 36 months(ranged 6 to 99 months) . Five cases (1.3％) in the T1 patients relapsed,recurrencefree survival (RFS) rate was 98.7％;In the T2 patients,7 cases (3.6％) relapsed,1 of them had local recurrence and died of lung metastasis,and the RFS rate was 96.4％.Univariate analysis revealed that T stage,Fuhrman grade,tunor necrosis,tumor pseudocapsule,lymphovascular invasion,collection system violation,anemia,and high platelet were significantly associated with RFS of patients.Multivariate analysis found that T stage (HR =1.524,95 ％ CI 1.326-1.926,P =0.001),Fuhrman grade (HR =1.600,95 ％ CI 1.035-2.364,P =0.022),tumor necrosis (HR =2.315,95％ CI 1.523-3.624,P =0.001) were independent risk factors for the RFS of patients with renal cell carcinoma after retroperitoneal laparoscopic partial nephrectomy.Conclusion High T stage,high Fuhrman grade and tumor necrosis were independent risk factors for the RFS of patients with renal cell carcinoma after retroperitoneal laparoscopic partial nephrectomy.

Objective To investigate the expression of insulin-like growth factor Ⅱ mRNA binding protein 3 (IMP3) in non-muscle invasive bladder cancer and its relationship with the tumor recurrence and progression.Methods IMP3 protein expression was detected by immunohistochemistry in 130 cases of nonmuscle invasive bladder cancer specimens who underwent transurethral resection the first time at Beijing Chao-Yang hospital,from October 2010 to October 2013.Besides,we analyzed 20 cases of muscle-invasive samples and 20 benign tissues adjacent to cancer as control.The 130 patients were followed up by telephone and other methods.According to the UICC-TNM standard.Survival analysis was calculated by using the Kaplan-Meier method,and the difference in survival curves was analyzed by using the log-rank test.For multiple analyses,The Cox proportional hazards regression model was used.Results The positive expression rate of IMP3 in 130 patients with non-muscle invasive bladder cancer was 59.2％ (77/130),of which 30.0％ (39/130) was weak expression,29.2％ (38/130) was strong.However there was 80.0％ (16/20) in muscle-invasive specimens,of which 20.0％ (4/20) was weak,60.0％ (12/20) was strong (P =0.011).IMP3 was not detected in all benign tissues adjacent to cancer (P ＜0.001).All the 130 patients were followed-up for 5 to 69 mnonths,45 cases experienced disease recurrence,20 patients had progressed and 12 cases died.IMP3 expression was significantly related to higher tumor stage (P ＜ 0.001),high tumor grade (P =0.014),and tumor recurrence (P =0.003).Kaplan-Meier plots and log-rank tests showed that patients with IMP3-positive tumors had a lower disease-free survival (P =0.002) and progression-free survival rate (P =0.010) than those with IMP3-negative tumors.In the multivariable Cox analysis,we found that IMP3 protein was an independent predictor of disease-free survival (P =0.010) in non-muscle invasive urothelial carcinoma of bladder.Conclusions IMP3 was not expressed in benign tissue adjacent to cancer,whereas highly expressed in bladder cancer,and high IMP3 expression is an independent prognostic factor in NMIBC that can identify the patients with a high potential to relapse.

In recent years,the techniques of radical cystectomy and urinary diversion are continually improving,the surgical safety and efficacy are continually increasing.From open to laparoscopic to robotic,surgical techniques are progressing,but it is not yet possible to replace each other.With the development of equipment,laparoscopic radical cystectomy (LRC) and robotic-assisted laparoscopic radical cystectomy (RARC) can further improve the perioperative efficacy,the basic principles of open surgery can be copied,their perioperative oncologic outcomes are not inferior to open surgery.RALRC seems to have more advantages in pelvic lymph node dissection,long-term oncologic outcomes of the three techniques are simnilar,and open surgery seems to have more advantages in advanced tumors.Intracorporeal construction of the urinary diversion is still the mainstream,extracorporeal is likely to be the future direction.Laparoscopy is still the most suitable minimally invasive technique of radical cystectomy according to our national conditions.

Objective To study the efficacy and safety of intravesical chemotherapy combined with intravenous chemotherapy for high grade T1 (T1G3) bladder cancer after transurethral resection of bladder tumor(TURBT).Methods From January 2012 to December 2015,111 patients with high grade T1 (T1 G3) bladder cancer were retrospectively reviewed.Thirty-six patients received TURBT and intravesical chemotherapy and intravenous chemotherapy (group A),75 patients received TURBT and intravesical chemotherapy(group B).In group A,there were 28 males and 8 females,with average age 66.2 years;in group B,there were 59 males and 16 females,with mean age 67.9 years.There was no statistical difference between the two groups in age,sex,smoking history,tumor diameter,tumor number.1-year recurrence-free survival (RFS),1-year progression-free survival (PFS),intravenous chemotherapy adverse reaction were analyzed.Results All the patients were followed-up for 12 months.9 patients relapsed in group A,1-year RFS rate 75％,and the median RFS of the 9 patients was 9 (3-11) months.36 patients relapsed in group B,1-year RFS rate 52％,and the median RFS of the 36 patients was 7 (3-11) months.There was statistically significant difference between the two group(P =0.02).One patient progressed in group A,1-year PFS rate 97.2％,and the PFS was 9 months.Six patients progressed in group B,1-year PFS rate 92％,and the median PFS was 9.5(6-12) months.There was no statistically significant difference (P =0.305) between the two group.Only 1 case (3％) appeared Ⅲ° or above intravenous chemotherapy adverse reaction.Conclusions Intravesical chemotherapy combined with intravenous chemotherapy offers a better RFS rate than the intravesical chemotherapy alone for patients with T1G3 bladder cancer after TURBT,and there are very low rates of serious side effects.Intravenous chemotherapy may be considered as a new therapy strategy for T1G3 bladder cancer after TURBT.

Objective To cstimnate the diagnostic performance of computer tomography (CT) and magnetic resonance imaging (MRI) for detecting metastasis in pelvic lymph nodes with normal size in patients with bladder cancer.Methods hnaging of CT and MRI and clinical data of 118 patients who underwent radical cystectomy and pelvic lymphadenectomy were reviewed.The diagnostic efficacy of CT and MRI were analyzed when taking lymph nodes short axis diameter ≥0.3 cm and ≥ 1.0 cm respectively as diagnostic criterion of metastasis with corTelation of pathological results.Results 22.7％ (27/118) of patients were confirmed lymph nodes malignancies among 118 patients based on pathology.Totally 1 705 lymph nodes were detected in surgery and 119 of them were observed malignancy according to pathological presentation.The malignant nodes were mainly distributed in the perivesical (35.4％,41/119),internal iliac (12.6％,15/119),external iliac (30.3％,36/119),obturator region (21.0％,25/119) and presarcal region (1.7％,2/119).Imaging of CT and MRI showed that when taking nodes with ≥0.3 cm in maximum short-axis diameter (MSAD) as positive,the sensitivity (Se),specificity (Sp),and positive predictive values (PPV) were 16.0％,99.2％,54.2％ and 56.5％,99.2％,86.7％ respectively.While taking MSAD≥1.0 cm as malignant,the Se,Sp and PPV of CT and MRI were 6.2％,99.9％,83.3％ and 13％,100％,100％ respectively.When taking MSAD ≥0.3 cm as positive,the Se and PPV between CT and MR were statistically different(P ＜ 0.001 and P =0.036,respectively).When taking MSAD ≥ 1.0 cm as positive,there was no statistically difference (P =0.275 and 1.000,respectively).Conclusions The incidence of normal-sized lymph node metastasis was higher in patients with bladder cancer.At this phase the MRI evaluation was superior to that of CT.When the MSAD ≥ 1.0 cm,there was no significant difference between CT and MRI.
