RESUMO
Objective To evaluate the predictive values of serum neutrophil gelatinase-associated lipocalin (NGAL), urine NGAL, serum cystatin C (Cys-C) and serum creatinine (Scr) for early delayed graft function (DGF) in kidney transplant recipients. Methods Clinical data, blood and urine samples of 159 kidney transplant recipients were collected. All recipients were divided into the DGF group (n=42) and immediate graft function (IGF) group (n=117) according to the incidence of DGF. Clinical data of all recipients were analyzed. The changes of serum NGAL, urine NGAL, Cys-C and Scr levels were statistically compared between two groups. The predictive values of different markers for early DGF were assessed. Results Among 159 kidney transplant recipients, DGF occurred in 42 cases with an incidence rate of 26.4%. There were statistically significant differences in donor age, cold ischemia time of donor kidney and complement-dependent cytoxicity (CDC) between the two groups(all P < 0.05). Within postoperative 2 weeks, the serum NGAL levels in the DGF group were higher than those in the IGF group (all P < 0.05). The Cys-C, Scr and urine NGAL levels in the DGF group were higher compared with those in the IGF group within 3 weeks after kidney transplantation(all P < 0.001). Serum NGAL, urine NGAL, Cys-C and Scr levels had certain predictive values for early DGF in kidney transplant recipients. Cys-C yielded the highest predictive value with a cut-off value of 4.73 mg/L, sensitivity of 0.833, specificity of 0.812 and area under the curve (AUC) of 0.895. Conclusions Cys-C has higher predictive value for early DGF in kidney transplant recipients compared with serum NGAL, urine NGAL and Scr.
RESUMO
Sarcopenia is observed to have age-related loss of skeletal muscle mass, muscle strength and physical performance, which can be an effective prognostic indicator for postoperative complications and poor survival outcomes in tumor patients. Sarcopenia could reflect tumor-host interactions and has the advantages in accuracy and generality compared with traditional predictors. This paper reviews the research progress of sarcopenia in predicting the prognosis of genitourinary tumors.
RESUMO
Objective:To understand the application effect of traditional position and oblique supine lithotomy in percutaneous nephroscopy combined with ureteroscopy combined with double lithography, and explore the clinical nursing methods of oblique supine lithotomy.Methods:From January 2018 to January 2019 in our hospital, 82 patients with complicated calculi who underwent percutaneous nephroscopy combined with ureteroscopy and double lithoscopy were selected, and were divided into the control group ( n=40) and the observation group according to the random number table ( n=42). The control group took the lithotomy position after anesthesia, placed the ureteral stent tube and changed it to the prone position to complete the operation; the observation group placed the oblique supine lithotomy position to complete the operation after anesthesia, and there was no need to change the position during the operation. The posture time, blood pressure, heart rate, pulse oxygen, blood transfusion, bleeding, postoperative postural comfort and complications of the two groups were compared. Results:When placed in the position and at the end of the operation, the blood pressure of the control group was (109±31), (106±23) mmHg(1 mmHg=0.133 kPa), and the heart rate was (93 ±10), (95±15)times per minute; the blood pressure of the observation group was (130±19), (125±17)mmHg, the heart rate was (86±12), (85±9) times per minute, the difference between the two groups was statistically significant ( t value was 2.86-4.26, P<0.01). The posture time of the observation group was (12.4±3.0) min and the control group was (21.2±6.9) min with statistically significant difference between two groups( t value was 7.550, P<0.01). The number of uncomfortable patients in the observation group after operation was 3 cases and 7 cases occurred in the control group. The difference was statistically significant ( χ2 value was 2.450, P<0.05). Conclusion:It is safe and feasible to use the oblique supine lithotomy position in double -lens combined stone removal, which can reduce the patient's discomfort and complications, and effectively improve the surgical efficiency and quality.
RESUMO
Objective To evaluate the consistency among the results of preoperative midstream urine culture (PMUC), renal pelvis urine culture (RPUC) and renal stone (RSC) culture in patients undergoing percutaneous nephrolithotomy (PNL) and their relationship with postoperative infection. Methods This was a multicenter prospective study. From September 2014 to November 2017, 115 patients undergoing standard channel PNL or microchannel PNL in the First Affiliated Hospital of Soochow University and Yancheng Hospital of Traditional Chinese Medicine were selected. The PMUC, RPUC and RSC were detected. Samples for RPUC and RSC were obtained during PNL. The clinical data, stone configuration, stone burden and results of cultures were recorded. Results In the 115 patients, PMUC positive was in 4 cases (3.5%), RPUC positive was in 17 cases (14.8%), and RSC positive was in 16 cases (13.9% ); both RPUC and RSC positive were in 7 cases (6.1% ), among whom consistent pathogenic bacterium was in 6 cases, and inconsistent pathogenic bacterium was in 1 case; all the 3 cultures were positive in 1 case, but the types of pathogenic bacterium of PMUC were totally different with RPUC and RSC. At least one positive of the 3 cultures was in 29 cases (25.2% ). The types of pathogenic bacterium of PMUC were multidrug susceptible Escherichia coli and Staphylococcus aureus , and the types of pathogenic bacterium of RPUC and RSC were multidrug resistant pathogens and/or fungus. The consistency of pathogenic bacterium between PMUC and RPUC, RSC was very low; while the consistency of pathogenic bacterium between RPUC and RSC was very high (6/7). Postoperative infection occurred in 8 of 115 patients (7.0% , 5 cases of infective fever and 3 cases of urinary sepsis). In the 8 patients, PMUC was negative, PRUC positive in 4 cases, RSC positive in 7 cases, and both PRUC and RSC positive were in 3 cases. Conclusions PMUC can not accurately reflect the true situation of upper urinary tract renal calculi and pyelo-urine pathogenic bacterium. In patients with PNL postoperative infectious complications, the result of PMUC is often negative, but the results of RPUC and RSC are mostly positive. RPUC and RSC are helpful to detecting pathogenic bacterium in time, guiding the application of sensitive antibiotics, preventing and treating PNL postoperative infection.
RESUMO
Objective To study the effect of puncture length per cubic centimeter of prostate biopsy on the detection rate of prostate cancer. Methods The clinical data of 254 prostate cancer patients who had underwent the first prostate biopsy by transrectal ultrasound guidance from September 2013 to November 2017 were retrospectively analyzed. The patients were divided into prostate cancer group and non prostate cancer group according to biopsy pathologic results. The total prostate specific antigen (TPSA), prostate volume, puncture length per needle, puncture length per cubic centimeter of prostate, volume of per needle and percentage of the sampled prostate volume were compared between 2 groups, and the relationship between puncture length per cubic centimeter of prostate and prostate cancer detection rate were analyzed. Results Among the 254 patients, the prostate cancer was in 67 cases (prostate cancer group), and the benign lesion was in 187 cases (non prostate cancer group). The prostate cancer detection rate was 26.4% (67/254). There were no statistical differences in age, puncture length per needle and volume of per needle between 2 groups (P>0.05). The TPSA, puncture length per cubic centimeter of prostate and percentage of the sampled prostate volume in prostate cancer group were significantly higher than those in non prostate cancer group: (13.8 ± 6.8)×103 ng/L vs. (8.5 ± 3.9)×103 ng/L, (3.42 ± 0.12) mm/cm3 vs. (2.83 ± 0.18) mm/cm3 and (2.75 ± 0.31)% vs. (2.24 ± 0.25)%, the prostate volume was significantly lower than that in non prostate cancer group: (45.8 ± 15.5) cm3vs. (56.3 ± 13.8) cm3, and there were statistical differences (P<0.05). Receiver operating characteristic curve analysis showed that area under the curve was 0.628, 95% CI 0.561 to 0.695. The cutoff value of puncture length per cubic centimeter of prostate was 3.40 mm/cm3, with the sensitivity of 59.8% and the specificity of 64.8% . Conclusions The puncture length per cubic centimeter of prostate and percentage of the sampled prostate volume are important morphometric parameters in the determination of prostate cancer. The detection rate of prostate cancer is the highest , when puncture length per cubic centimeter of prostate is≥3.40 mm/cm3.
RESUMO
Objective To evaluate and compare the effectivity and safety of mini-percutaneous nephrolithotomy (mPNL) and flexible ureteroscopic lithotripsy (FURL) for diameter 10 to 20 mm renal stone in obese patients. Methods This was a multicenter prospective study. One hundred and ten obese patients (body mass index≥28.0 kg/m2) with diameter 10 to 20 mm kidney stone from January 2015 to May 2017 were selected. The patients were divided into mPNL group (58 cases) and FURL group (52 cases) according to the patients′ will. The operation time, hospitalization time, complication, one-stage stone removal rate and ultimate stone removal rate were compared between 2 groups. Results The operation time, hospitalization time and incidence of complication in FURL group were significantly lower than those in mPNL group: (66.7 ± 21.9) min vs. (85.7 ± 33.4) min, (72.5 ± 23.7) h vs. (120.8 ± 33.5) h and 9.6% (5/52) vs. 31.0% (18/58), and there were statistical differences (P<0.05). There were no statistical differences in the one-stage stone removal rate and ultimate stone removal rate between 2 groups (P>0.05). In aspect of postoperative bleeding, hemoglobin decreased after operation (15.8 ± 9.7) g/L in mPNL group; no hemorrhage occurred in FURL group, and no significant changes in hemoglobin were observed before and after operation. Conclusions Both mPNL and FURL achieve satisfactory stone-free rates in obese patients with diameter 10 to 20 mm renal stone. Compared with mPNL, FURL has shorter operation time and lower incidence of complication.
RESUMO
Objective To investigate the diagnostic accuracy of magnetic resonance imaging and ultrasound (MRI/US) fusion targeted biopsy (TB) and systematic biopsy (SB) in the patients with prostate specific antigen (PSA) in grey area.Methods The patients who received MRI/US fusion TB and SB in the First Affiliated Hospital of Soochow University between October 2015 and March 2018 were retrospectively reviewed.Eligibility criteria included:tPSA ranged 4 to 10 ng/ml;prebiopsy MRI found at least 1 suspected lesion;no prostate-related treatment history;no prostate biopsy history.A total of 93 patients were invloved.The median age,tPSA and prostate volume were 66 (30-85) years,7.18 (4.11-9.95) ng/ml and 42.01 (14.93-119.15) ml,respectively.Prebiopsy MRI found 136 suspected lesions,with the median PI-RADS of 3 (3-5) and lesion size of 7 (3-20) mm.All patients underwent MRI/US fusion TB followed by SB.The comparison of two protocols in detecting any prostate cancer (PCa) as well as clinically significant prostate cancer (CsPCa) were analyzed.Results Cancer detection rates for PCa in TB [34.40% (32/93)] was not different with SB [36.55% (34/93),P =0.759].There was no significant difference in the detection rate of CsPCa between TB and SB [20.43% (19/93) vs.24.73% (23/93),P=0.483].A total of 1 374 biopsy cores were sampled,among which 266 were TB cores and additional 1108 were SB cores.The positive rate of TB cores [24.81% (66/266)] was significantly higher than SB cores [9.84% (109/1 108),P <0.001].Conclusions In the patients with PSA in grey area,MRI/US fusion TB achieved similar cancer detection rate compared with SB using only few biopsy cores.Therefore,TB was appropriate for patients with MRI suspicions.Moreover,combination of TB with SB can achieve the highest cancer detection rate.
RESUMO
Objective To investigate the relationship between the interleukin (IL)-35 and the recovery of renal graft function. Methods Clinical data of 45 recipients receiving renal transplantation from donation after cardiac death (DCD) were retrospectively analyzed. According to the presence of delayed graft function (DGF) after renal transplantation, all recipients were divided into the immediate graft function (IGF) group (n=32) and DGF group (n=13). The serum creatinine (Scr) level and estimated glomerular filtration rate (eGFR) in the recipients were statistically compared between two groups at 1, 2, 3, 7, 14, 28 d and 3, 6 and 12 months after renal transplantation. The IL-35 levels in the serum and urine samples of the recipients were statistically compared between two groups at 1, 2, 3, 7, 14, 28 d following renal transplantation. Results In the DGF group, the renal function was restored slowly. Compared with the IGF group, the Scr level was significantly higher, whereas the eGFR was considerably lower in the DGF group at postoperative 7 d (both P<0.05). At 1 year after surgery, there was no significant difference in the Scr level between two groups. Compared with the IGF group, the eGFR in the DGF group was significantly lower at postoperative 1 year (P<0.05). At 1, 2, 3, 7, 14 d after operation, the serum levels of IL-35 in the DGF group were evidently lower than those in the IGF group (all P<0.05). Compared with the IGF group, the serum level of IL-35 in the DGF group was significantly increased at postoperative 28 d (P<0.05). At postoperative 1, 2, 3, 7 d, the IL-35 levels in the urine samples in the DGF group were significantly lower than those in the IGF group (all P<0.05). At postoperative 14 and 28 d, the IL-35 levels in the urine samples did not significantly differ between two groups (both P>0.05). Conclusions The low levels of IL-35 in the serum and urine of recipients after renal transplantation are associated with the incidence of DGF to certain extent, prompting that excessively weak systemic and local anti-inflammatory responses early after renal transplantation and uncontrolled excessive inflammatory response are probably the pivotal causes of DGF.
RESUMO
Objective To evaluate the feasibility and efficacy of intra-cavity contrast enhanced ultrasound (ICCE-US) in percutanous nephrolithotomy for nephrolithiasis patients with slight or no hydronephrosis.Methods From March 2016 to March 2017,ICCE-US-guided PCNL was performed in 35,patients who had kidney stones with slight hydronephrosis in 11 and without hydronephrosis in 24.The sample comprised 20 males and 15 females,including 10 with renal pelvic calculi alone,17 with renal pelvic calculi combined with renal calyx calculi,and 8 with partial staghorn calculi.Mean age was 46.8 years (ranging,28-75 years).The size of calculi ranged from 2.5 cm to 5.0 cm [mean(3.6 ± 1.2) cm].In the prone position,the preferred calyces are the posterior ones,which were enhanced by sulfur hexafluoride microbubbles (SonoVue) retrogradely injected through ureteral catheter.An 18-gauge needle was inserted toward the desirable calyx.Successful renal entry was confirmed by administration of ultrasound contrast agents into the collecting system via the needle regardless of whether spontaneous urine drainage was observed.A guidewire was passed through the needle to renal collecting system.Subsequently,the needle was removed.And the renal tract was dilated to F18-F20 size with dilators.Finally,holmium laser lithotripsy was performed through nephroscopy.Results Posterior calyces and its fornix were revealed under contrast-enhanced ultrasound in all patients.The successive access rate was 100%.The average time for establishing the access was (8 ±2.6)min (ranging 5-10 min).The mean number of needle passes was (1.5 ± 0.3) times per kidney,ranged from 1 to 3 times.Hemoglobin level averagely reduced (11.3 ± 3.7) g/ L (ranging 6-15 g/L) within 24 hours postoperatively.No major complications,such as adjacent organs injuries or collecting system perforation were observed.No blood transfusion was needed.The mean hospital stay was (5.6 ± 1.2) days (ranging 5-7 days).The stone-free rate was 91.4% (32/35).Conclusions ICCE-US can demonstrate clearly about the posterior calyces and its fornix as well as puncture needle site by contrast enhancement in the nephrolithiasis patients with slight or no hydronephrosis.It has the potential to improve the accuracy and successive rate of puncture resulting in a decrease in the puncture-related complications.

RESUMO
Objective To estimate the value of transrectal ultrasound/magnetic resonance imaging (TRUS/MR) fusion targeted prostate biopsy(targeted biopsy,TB) in the biopsy naive patients.Methods Between September 2015 and September 2016,91 patients with PI-RADS ≥ 3 suspicious regions on the multiparametric magnetic resonance imaging (mpMRI) were retrospectively evaluated.The age of patients was 46-83 years (median 68).Serum PSA level before biopsy was 1.2-85 ng/ml (median 11.2 ng/ ml),in which 36 cases with PSA < 10 ng/ml,30 cases 10-20 ng/ml,and 25 cases > 20 ng/ml.Two-core TB using real-time virtual sonography (RVS) platform for mpMRI-suspicious lesions was followed by 12-core systematic biopsy (SB).The detection rates for any cancer (PCa) and clinically significant prostate cancer (CsPCa) were compared between TB and SB.Results The total detection rate for PCa was 57.1%,with a comparable positive rate between TB (44.0%) and SB (51.7%) groups which did not significantly differ (P =0.14).The proportion of CsPCa in TB group was higher than that in SB group (80.0% vs.68.1%,P =0.21).In TB group,detection of PCa for grade 5 lesions was significantly higher than that for grade 3 lesions (77.1% vs.10.3%,P <0.001).Detection of PCa was comparable between TB and SB groups in different regions of PSA < 10 ng/ml,10 ~ 20ng/ml and > 20ng/ml (27.8% vs.36.1%,50% vs.56.7%,60% vs.68%,respectively).Conclusions This study revealed a similar rate of prostate cancer detection between 2-core targeted biopsy guided by TRUS/MR fusion and 12-core random biopsy in different PSA regions for no prior biopsy men.TB maybe tend to detect high proportion of CsPCa.PI-RADS is instructive to select appropriate patients for TB.
RESUMO
Clinical data of 23 patients with T2a bladder cancer admitted from March 2008 to August 2013 were retrospectively analyzed.Among 23 patients,11 cases were treated with transurethral resection (TURBT) plus arterial catheterization chemotherapy (study group) and 12 cases were treated with radical cystectomy (control group).The overall survival time and recurrence free survival time of two groups were compared.Patients in study group were followed up for 20-68 months,recurrence occurred in 5 cases (5/11),including 4 cases of invasive recurrence;patients in control group were followed up for 2 ~86 months,1 case had superficial recurrent and underwent TURBT,2 cases dead due to bladder tumor.During the course of chemotherapy,the main adverse effects were digestive reaction (7/11),fever (4/11),bone marrow suppression (2/11),symptomatic treatment was given,which was tolerated.There were no significant differences in overall survival time and recurrence free survival time between two groups (P > 0.05).The quality of life of study group was better than that of control group (P < 0.05).It is suggested that the arterial interventional chemotherapy combined with transurethral resection for T2a stage invasive bladder cancer has a certain curative effect with the advantage of preservation of bladder function and higher quality of life.
RESUMO
Objective To assess the clinical significance of red blood cell distribution width ( RDW) in patients undergone prostate biopsy.Methods A total of 793 consecutive patients were enrolled, with 359 cases of prostate cancer ( PCa) and 434 cases of benign prostate hyperplasia ( BPH) diagnosed by pathological examination.The difference of RDW level between PCa and BPH patients was analyzed by T-test.Logistic regression was used to evaluate the contributed factors such as RDW, PSA, HB, WBC, PLT, TG and age.Areas under operating characteristic curves ( AUC) were used to compare the predictive power of RDW for the presence of PCa among different PSA level groups.The difference of RDW level was also analyzed in different groups divided by PSA, Gleason score and clinical stage respectively.Simple linear regression analysis was performed to explore the association of RDW with PSA, Gleason score and clinical stage.Results The means of RDW were ( 13.38 ±1.11 )%in patients with PCa which were higher than those with BPH (12.75 ±0.62)%(P20 ng/ml, the highest in the PSA groups.The RDW was positively correlated with increasing risk evaluated by PSA, Gleason score or clinical stage (P20 ng/ml.Therefore, RDW can be used to evaluate the risk of prostate cancer.
RESUMO
Objective To assess the clinical significance of serum high sensitive C-reactive protein (hs-CRP) in patients undergone prostate biopsy.Methods A total of 273 consecutive patients were enrolled,aged 44-95 years (mean,69 years).All the patients underwent prostate biopsy.The pathological findings showed 96 cases with prostate cancer (PCa) and 177 cases with benign prostate hyperplasia (BPH).The difference of hs-CRP level between patients with PCa and those with BPH was analyzed.The positive prostate biopsy rate was compared between the patients with high hs-CRP level and those with normal hs-CRP level.Logistic regression was used to evaluate the effect of factors such as hs-CRP,tPSA,PSA density,prostate volume and age on prostate biopsy.Results The medians (interquartile range) of hs-CRP were 3.22 mg/L (1.22-9.84 mg/L) in patients with PCa and 1.24 mg/L (0.55-2.76 mg/L) in those with BPH,respectively,with significant difference(P<0.05).The positive prostate biopsy rate in patients with high hs-CRP (> 3 mg/L)was 55% (51/92),higher than that in those with normal hs-CRP (≤ 3 mg/L).The odds ratio of hs-CRP was larger than that of all other factors analyzed including tPSA,prostate volume and age according to the Logistic regression analysis.Conclusions Elevated serum hs-CRP level is associated with increased positive prostate biopsy.Serum hs-CRP acts as an independent factor increasing the positive prostate biopsy rate in patients undergone prostate biopsy.

Objective To evaluate the value of ATP content of CD4+ T lymphocytes in the diagnosis of infection and its correlation with drug concentrations in renal transplant recipients.Methods 45 renal transplant recipients were reviewed from May 2010 to October 2011.There were 33males and 12 females,aged from 21 to 58 years old.The recipients were divided into non-infection group (n =34) and infection group (n =11) according to their clinical manifestation.11 cases of infection were diagnosed by the chest X-ray,CT imaging manifestations and etiological examination,among them 5 cases were pulmonary infection,4 cases were upper respiratory infection,1 case was urinary tract infection and 1 case was perineal abscess.23 healthy volunteers were enrolled as the control group.They were detected ATP content of CD4+T lymphocytes by Immuknow method.Thetrough concentrations of the FK506 and CsA were detected by microparticle enzyme immunoassay and fluorescence polarization immunoassay,respectively.The hs-CRP concentration was detected by immunoturbidimetry.Results The ATP content of CD4+ T lymphocytes of the control group,non infection group and the infection group were (295±74) μg/L,(35± 189) μg/L and (212± 155) μg/L respectively.The levels of ATP of infection group were obviously lower than the control group and non-infection group.There were statistically differences (P <0.05).24 recipients were followed up dynamicly.There were 4 cases whose ATP value was lower than the postoperative average levels in 5 infection recipients.The hs-CRP concentration of infection group were (12.4±4.8) mg/L,obviously higher than the non infection group's (3.3 ± 4.7) mg/L and the control group' s (0.5 ± 0.5) mg/L.There were statistically differences (P<0.05).The ATP content of CD4+ T lymphocytes were no significant associated with drug trough concentrations (P>0.05).Conclusions Low ATP level after renal transplantation is a risk factor for infection recipients.Immuknow cell function assay can make up for the inadequacy of the drug concentration monitoring,reduce the risk of infection,and guide clinical immunosuppressive adjustment.
RESUMO
[Abstract] Objective To define the age-specific normal reference values of prostate specific antigen (PSA) and related parameters in Chinese middle-aged and elderly men.Methods From April 2007 to November 2011,serum PSAs of over 22 055 men aged more than 40 years old in our medical examination center were statistically analyzed.The men was divided into five groups by a 10-year-old interval.Total PSA (tPSA),free PSA (fPSA) and prostate ultrasound results were recorded.The free-total PSA ratio (f/t),PSA density (PSAD) and PSA velocity (PSAV) were calculated.By convention,the 95th percentile (P95)was used as the upper limit value,and the 5th percentile (P5) as the lower limit value.Results The tPSAs were positively correlated with age (r=0.349,P<0.001).f/t was negatively correlated with age (r=-0.154,P<0.01).Although f/t was significantly different (P<0.001) among each age group,P5 of all groups were 0.18.PSAD was significantly different (P<0.001) between men over and under 70 years,with P95 as 0.09 and 0.15,respectively.PSAD had a positive correlation with age (r =0.263,P<0.01).The significant difference of PSAV raised between men over and under 60 years,with P95 as 0.21 and 0.58,respectively.PSAV was positively correlated with age (r=0.130,P<0.01).Conclusions PSA,PSAD and PSAV are positively correlated with age,while f/t is negatively correlated with age.The normal range of f/tis 0.18-1.00 for Chinese men over 40 years old.PSAD's normal ranges are <0.09 and <0.15 in Chinese men over and under 70 years,respectively.The normal range of PSAV are <0.21 and <0.58 for Chinese men over and under 60 years,respectively.
RESUMO
Objective To evaluate the feasibility and effectiveness of bladder-preserving local resection combined with intra-artery chemotherapy for patients with T1G3 bladder cancer.Methods Thirty five cases with T1G3 bladder cancer were analyzed retrospectively. Patients were all treated by bladder-preserving local resection combined with intra-artery chemotherapy. Results Thirty five cases were followed up. The time of follow-up ranged from 7 to 116 months,and mean time was(66.0±18.3)months.The 5 year recurrence and bladder-preserving rate were 48.6 %(17/35)and 68.6 %(24/35),respectively.The overall and tumor specific survival at 5 years was 77.1% (27/35)and 82.9 % (29/35).The effect of bladder-preserving local resection plus intra-artery chemotherapy was satisfactory. Moreover, intra-artery chemotherapy had no obvious side effects.Conclusion Bladder-preserving local resection combined with intra-artery chemotherapy not only can retain normal bladder function, decrease in the recurrence, but also does not reduce the survival rate. It is an effective treatment for some patients with T1G3 bladder cancer instead of cystectomy over-treatment.
RESUMO
Objective To detect the gene expression of PCA3 and PSA in peripheral blood and urine simultaneously to investigate whether PCA3 combining PSA gene could become new markers for diagnosis of Pca. Methods From June 2009 to December 2009,the initial urine after prostatic massage and the peripheral blood specimens were collected from 37 patients with PCa and 68 patients with BPH that were pathologically confirmed,g patients with urinary stone were used as normal control,the expression of PCA3 and PSA mRNA of mononuclear cells in urine sediments and peripheral blood were detected by fluorescence real-time quantitative PCR,with β-actin mRNA as internal control. Results The sensitivity and specificity of the expression of PCA3 mRNA in peripheral blood for diagnosis of prostate cancer were 48.6% and 100% respectively.ROC curve analysis was performed for the PCA3 score and the area under the ROC curve was 0.908.Using 64.6 as the cutoff,the sensitivity was 81.1% and the specificity was 86.8%.In group with serum tPSA value <4 pg/L,the positive rate and negative rate of urinary PCA3 score for diagnosing prostate cancer were 80% (4/5) and 89.4% (20/22) respectively.In group with serum tPSA value 4 - 10 μg/L,the positive rate and negative rate of urinary PCA3 score were 66.7% ( 2/3 ) and 84.2%(16/19) respectively.In group with serum tPSA value > 10 μg/L,the positive rate and negative rate of urinary PCA3 score were 82.8% (24/27) and 81.5% (22/27) respectively.The sensitivity of simultaneous detection of PCA3 mRNA in peripheral blood and urinary PCA3 score was 86.5%. Conclusions The expression of PCA3 mRNA in peripheral blood was a specific marker for the diagnosis of PCa.The simultaneous detection of PCA3 mRNA in peripheral blood and urinary PCA3 score could increase the sensitivity for the diagnosis of PCa.
RESUMO
Objective To evaluate the effect of transurethral feedback microwave thermotherapy with the ProstaLund CoreTherm Device (PLFT) in benign prostate hyperplasia ( BPH ) patients with high risk factors 24 months after treatment.MethodsSixty-two BPH cases with high risk factors of aged ≥ 80or complicating severe conditions of no less than one organ or system,were treated with PLFT under urethral local anesthesia.The average pre-treatment prostate volume,international prostate symptom score (IPSS),quality of life score (QOL) and maximal urinary flow (Qmax) were 62.03 ml,23.19,4.58 and 4.33 ml/s,respectively.The changes of prostate volume,IPSS,QOL and Qmax at 3 months,12 months and 24 months after treatment were analyzed.ResultsAll patients tolerated well of PLFT performed in common therapy room except lightly bleeding,minor infection and temporary incontinence.There was no severe surgical adverse event.After 3 months,the prostate volume reduced to 43.85 ml,IPSS decreased to 11.63,QOL decreased to 2.44,Qmax rose up to 11.44 ml/s; The average values were 45.10 ml,12.23,2.61 and 10.91ml/s at 12 months after treatment.The corresponding values were 45.80 ml,12.37,2.66 and 10.82 ml/s,respectively at 24 months after treatment.Compared with pre-treatment,all the parameters showed significant improvement ( P < 0.01 ).ConclusionsPLFT is one of the effective and safe treatment options for BPH patients with high risk factors.It can be safely used on day-surgery patients.The best effect appears at 3 months after treatment.
