Objective To evaluate the efficacy and safety of TUEVP vs TURP for treating benign prostatic hyperplasia(BPH).MethodsLiferatures on randomized controlled trials(RCT),non-randomized controlled trials(NRCT) and retrospective controlled trials of both Chinese and English studies about TUEVP vs TURP for the treatment of BPH all over the world were searched by Pubmed,Ovid,ScineceDirect,NGC,EBSCO,EMBASE,CNKI,CBM,as well as manual search of four Chinese journals: Chinese of Journal of Androloy,National Journal of Androlgy,Chinese Journal of Urology,Journal of Clinical Urology.Two reviewers independently screened the studies for eligibility,evaluated the quality and extracted the data from the eligible studies,with confirmation by cross-checking.Divergences of opinion were settled by discussion or consulted by the expert.Meta-analysis was processed by Rev Man 5.0,fail-safe number(Nfs) was performed by SAS8.0.ResultsSeventeen RCTs involving 2413 men were enrolled the inclusion criteria in Meta analysis.The baseline of patients' characteristics was comparable in all the studies.By evaluating the relevant indicators,side effects and complications between TUEVP and TURP,the statistically significant differences of pooled estimates suggested a benefit of TUEVP over TURP for bladder wash-out time,catheterization time,hospital stay,incidence of ED(20.6% vs 29.0%).In contrast,pooled estimates of the difference favoured TURP over TUEVP for MFR and incidence of postoperative secondary hemorrhage(7.9% vs 3.6%).ConclusionThis formal meta-analysis suggests that both TUEVP and TURP in patients with BPH provide comparable improvements,whose efficacy and safety is similar.While comparative analysis is limited by the methodological shortcomings of the underlying studies and the short follow-up,both TURP and TUEVP may offer distinct advantages.More high quality trials with large sample and longer follow-up are proposed,which will provide more evidence about evidence based medicine.

Adrenal tuberculosis is still the main cause of primary adrenal insufficiency (Addison Disease) in China. A case of bilateral adrenal tuberculosis without PAI symptoms was admitted to Department of Urology, Shanxi Provincial People’s Hospital. Pathological report showed adrenal tuberculosis. We present an overview and discuss how to diagnose early adrenal tuberculosis and reduce misdiagnosis rate so as to preserve residual adrenal function to the greatest extent.

Objective To study the expression and clinical significance of matrix metalloproteinase 2 (MMP-2) in chinese patients with bladder cancer. Methods The relevant original articles published in journals from 1998 to 2014 were selected. The ratio of the case group and the control group (OR value) regarded as an effect index. Then the original data were analyzed using Meta analysis software RevMan 5.0, the combined OR values and 95%confidence interval were calculated, and the forest map was draw. Results 13 studies involving 692 patients that met the inclusion criteria were included in the Meta analysis. The OR values of bladder cancer tissue group and normal bladder tissue group, superficial bladder cancer group and invasive bladder cancer group, and low grade bladder cancer group and senior bladder cancer group were 45.83, 0.22 and 0.31, respectively. The positive rates of MMP-2 in bladder cancer tissue group, invasive bladder cancer group and advanced bladder cancer group were significantly higher than those in normal bladder tissue group, superficial bladder cancer group and low grade bladder cancer group (all P< 0.05). Conclusions The high expression of MMP-2 has a certain effect in bladder cancer. The detection of MMP-2 contributes to the understanding of the biology of bladder cancer, and provides information for clinical treatment and prognosis.

Objective To evaluate the safety and efifcacy of Laparoscopic partial nephrectomy (LPN) versus 1aparoscopic cryoablation (LCA) for the small renal tumors (SRMs).Methods The databases of PubMed, SCI, Ovid, the Cochrane Library, CNKI, CBM, VIP and Wangfang Data were searched to controlled clinical trial about LPN versus LCA for the treatment of small renal tumor. The retrieval time span was from inception to Apr 2016. The studies were screened according to the inclusion and exclusion criteria, the date were extracted and the quality was evaluated by 2 reviewers independently. And then the Meta-analysis was conducted using RevMan 5.3 software.Results 9 studies were included, and 748 cases were involved. The meta-analysis showed that comparing with LPN, the operation time of LCA was shorter [MD = 42.75, 95 % CI (12.19~73.31),P = 0.006], less intraoperative blood loss [MD = 190.73, 95 % CI (126.67~254.78),P = 0.000], shortening hospital stay [MD = 2.23, 95 % CI (0.17~4.28),P = 0.030], lower transfusion rate [OR^ = 3.54, 95 % CI (1.18~10.59),P = 0.020], lower rate of postoperative glomerular ifltration levels [MD = 10.30, 95 % CI (5.38~15.24),P = 0.000], less complications [OR^= 3.90, 95 % CI (1.84 ~ 8.24),P = 0.000], higher risk of local recurrence [OR^ = 0.13, 95 % CI (0.04 ~ 0.44),P =0.000], higher risk of distant metastases [OR^ = 0.16, 95 % CI (0.03 ~ 0.78),P = 0.020], but there were no signiifcant differences in postoperative creatinine rise and transfusion rate (P > 0.05).Conclusions LCA has advantage in perioperative period results and protect renal function. But LCA has a higher local recurrence and distant metastasis risk, short-term and medium-term efficacy considerably, long-term effect is not clear, therefore, in the choice of surgical cases still need to be careful.

Objective:To explore the influencing factors of postoperative chronic kidney disease (CKI) in patients with primary aldosteronism (PA).Methods:The clinical data of 103 patients who underwent adrenalectomy for PA in our center from August 2018 to August 2019 were analyzed retrospectively. There were 53 males and 50 females, aged (47.02±10.06) years old, including 27 diabetes patients (26.2%). The body mass index (BMI) were (24.47±3.24) kg/m 2, tumor maximum diameter were (15.61±5.66) mm, preoperative systolic blood pressure were (166.93±12.22) mmHg(1 mmHg=0.133 kPa), preoperative blood potassium were (3.35 ± 0.48) mmol/L, plasma aldosterone concentration (PAC) were (55.75±8.56)ng/dl, aldosterone-renin ratio(ARR) were (165.13±38.21) and preoperative glomerular filtration rate (GFR) were (77.96±14.77) ml/(min·1.73m 2). All patients underwent laparoscopic adrenalectomy. The operation time and bleeding volume were recorded. The GFR, blood potassium, PAC and ARR were recorded at the third month after surgery. The paired sample t test was used to compare GFR before and after surgery. Pearson correlation analysis was used to evaluate the correlation between the parameters and GFR after surgery. The independent predictors of GFR≤60ml/(min·1.73 m 2) were analyzed by univariate and multivariate logistic regression. Results:The surgery time were (85.37±21.66) min, and the bleeding volume were (10.54±4.84) ml. GFR (62.66±8.53) ml/(min·1.73 m 2) at 3 months after surgery was significantly different from that before surgery ( P<0.01). Univariate analysis showed that age ( OR=1.36, P<0.01), preoperative GFR ( OR=0.81, P<0.01), preoperative blood potassium ( OR=2.95, P=0.02), preoperative PAC ( OR=1.28, P<0.01) and preoperative ARR ( OR=1.08, P<0.01) were significantly correlated with postoperative CKI. In Pearson analysis, older age ( r=-0.51, P<0.01), lower preoperative GFR ( r=0.62, P<0.01), lower preoperative blood potassium( r=0.41, P=0.02), higher preoperative PAC ( r=-0.49, P<0.01) and higher preoperative ARR ( r=-0.56, P<0.01) increased the risk of CKI. Multivariate logistic regression analysis showed that age ( OR=1.26, P=0.05), preoperative GFR ( OR=0.79, P=0.02) and preoperative PAC( OR=1.29, P=0.01) were independent risk factors for postoperative CKI. Conclusions:CKI may occur in PA patients after adrenalectomy. PA patients with older age, higher preoperative PAC, higher preoperative ARR, lower preoperative blood potassium and lower preoperative GFR are more likely to have CKI. Age, preoperative GFR and preoperative PAC were independent predictors of CKI.

Objective To analysis the clinical features,diagnosis,treatment and prognosis of adrenal eosinophilic tumor with low testosterone levels.Methods The clinical data of a 22 years old male patient with adrenal eosinophilic tumor and low testosterone levels was analyzed.Blood pressure was 151/88 mmHg.The patient got bilateral gynecomastia.His bilateral testicular was soft and became smaller,with short penisr.Endocrine examination results showed:Estradiol 666 pg/ml,Prolactin 19.08 ng/ml,Testosterone 0.18 ng/ml,follicle stimulating hormone ＜ 0.2 U/L.The CT showed the mass density of soft tissue in the left adrenal region with diameter 7 cm,which was inhomogeneous and enhanced.There were many small vessels enhanced in the CT arterial phase,and the blood flow in the tumor was abundant.Clinical diagnosis of left adrenal tumor was pheochromocytoma.The patient underwent laparoscopic left adrenal tumor resection.The left adrenal gland was located in the superior pole of the left kidney,and there was an independent supply of the artery.Results Pathological result showed the tumor weigh was 60 g,7 cm in diameter and brown in section.The tumor cells were arranged in solid nests or acini,with more eosinophilic granules in cytoplasm.The nuclei was round and the nucleoli was located in the center,had clusters of pleomorphic and clustered cells.The tumor was wrapped in a thick fibrous envelope,mainly consisted of eosinophils,granulation tissue.There was no necrosis,mitosis,and vascular invasion.Immunohistochemical staining showed that the expression of CD56 and syn protein was positive.Pathological diagnosis was left adrenal eosinophilic tumor.After 4 months,the blood testosterone levels rose to 3.90 ng/ml,the blood pressure returned to normal (118/75 mmhg).The estradiol (21 pg/ml) was significantly inhibited.The patient began to appear beards and breasts became smaller.There were no signs of clinical or imaging recurrence.After 16 months follow-up,serum testosterone was 4.68 ng/ml and serum estrogen levels dropped to 33 pg/ml.Semen routine showed no sperm.Conclusions The clinical morbidity of functional adrenocortical oncocytoma with low testosterone levels and high estradiol levels is low.The pathological components are mainly eosinophilic granulation tissue.The adrenocortical oncocytoma are rare and preoperative diagnosis is difficult.Clinical manifestation,imaging examination and adrenal biochemistry examination should be considered to determine the localization and qualitative of tumor.Minimally invasive surgery is an effective treatment.The close follow-up after operation is essential.

Objective To investigate the diagnosis and treatment of active adrenal tuberculosis.Method The clinical data of 1 patients with adrenal tuberculosis was retrospectively analyzed and the related literatures were reviewed.The male patient,54 years old,complained abuot the dry cough and intermittent fever for 9 months.He was found the left adrenal gland tumor for 1 weeks and admitted to our hospital on November 1st,2016.The physical examination showed the obvious left kidney percussion tellderness.The local hospital,considered the left adrenal tumor.The pathological diagnosis of left adrenal tumor by biopsy was chronic inflammation.The patient accepted anti-inflammatory therapy,but his symptom was not relieved.In our hospital,blood bacterial culture and urine bacterial culture and PPD was negative.Blood tuberculosis antibody was positive.Triple acid-fast bacilli were negative in urine.Chest CT did not exclude the interstitial pulmonary tuberculosis.Adrenal contrast-enhanced CT showed mild enhancement,strip calcification shadow.Primary diagnosis was left adrenal tumor,which the abscess and tuberculosis could not to be excluded.Then,the patient accepted regularly anti-tuberculosis therapy (Isoniazid,0.3 g/d,rifampicin,0.45 g/d,ethambutol,0.6 g/d).Mter 3 days,his temperature returned to normal.Since the left adrenal mass was too large,which was about 6.8 cm × 5.5 cm,to distinguish with the tumor,the patient accepted successfully retroperitoneal adrenal tumor resection two weeks later.The left adrenal tumor surface was greyish and yellow,which was adherent with spleen and pancreas.After carefully separating,the tumor was successfully removed.Result The operation was successful,which last 85 min.Intraoperative blood loss was about 50 ml.Pathological report showed adrenal tuberculosis.The patients accepted regularly antituberculosis therapy(Isoniazid,0.3 g/d,rifampicin,0.45 g/d,ethambutol,0.6 g/d) for half a year,and followed up for 1 year after operation.No further hormone replacement therapy was used.No fever was noticed and his rhythm cortisol level was normal.Conclusions Adrenal mass associated with recurrent fever,should be suspected as adrenal tuberculosis if antibiotic therapy is not effective.If the adrenal CT showed adrenal calcification associated with the ectepic tuberculosis,patient should be diagnosised active adrenal tuberculosis.They should accept anti-tuberculosis treatment.However,if the volume of tuberculosis is large,or not to exclude tumor possibility,we recommend to proceed adrenal tumor resection for diagnosis.
