Objective To discuss the safety of Rh-positive patients receiving kidney grafts from Rh-negative cadaver donor. Methods On November 29 th 2013, two Rh-positive patients received renal transplantation with kidney grafts from Rh-negative cadaver donor at the Department of Urinary Surgery of Xijing Hospital,the Fourth Military Medical University. The clinical data of the two patients were analyzed retrospectively and the relevant literatures were reviewed. Results The two patients underwent renal transplantation successfully and no hyperacute rejection or acute rejection occured after the surgery.The two patients were followed up for 12 months.The kidney grafts survived well and the patients had no obvious discomfort.Conclusions Through enhanced immunosuppression before operation,sufficient perfusion and close postoperative monitoring,it is safe for Rh-positive patients receiving kidney grafts from Rh-negative cadaver donor.

Objective:To explore the preoperative 68Ga-PSMA PET/CT examination on the guidance of surgical strategies for high-risk prostate cancer patients and the influence of positive surgical margins after surgery. Methods:The clinical data of 118 patients with high-risk prostate cancer who underwent robot-assisted laparoscopic radical prostatectomy from June 2019 to December 2020 in Xijing Hospital of Air Force Military Medical University was retrospectively analyzed. 47 patients received 68Ga-PSMA PET/CT examination before surgery (study group), and 71 cases without 68Ga-PSMA PET/CT examination before operation ( control group). There was no statistically significant difference in the age [69 (63, 76) vs. 67 (64, 74) years], PSA [PSA≤20ng/ml: 9.91 (6.00, 13.67) vs. 11.64 (8.15, 15.44) ng/ ml, PSA> 20ng/ml: 66.53 (53.66, 195.30) vs. 63.18 (30.08, 148.05) ng/ml], preoperative clinical staging (T 2/≥T 3: 21/26 cases vs. 34/37 cases), and Gleason score [8 (7, 9) vs. 8 (7, 9) points] (all P>0.05) between study group and control group. Both groups underwent robot-assisted laparoscopic radical prostatectomy. The surgical plan was based on the PSMA PET/CT and MRI results in study group and control group respectively. First, ensure that all tumors are removed, and secondly, preserve the patient's urethral length as much as possible to ensure postoperative urinary control.If there is seminal vesicle invasion, expand the scope of resection as needed. If lymph node metastasis is shown, lymph node dissection is performed. For those with negative lymph nodes in imaging studies, if enlarged lymph nodes are found during the operation, lymph node dissection is also performed. After the operation, the perioperative results and surgical margins of the two groups were compared, and the correlation between the PSA value and the SUVmax value of prostate cancer tissue was analyzed. Results:The operations of the two groups were successfully completed, and there was no transfer to open surgery. The operation time of the study group was shorter than that of the control group [175 (155, 205) min vs. 205 (155, 235) min, P=0.003], and the positive rate of resection margin was significantly lower than that of the control group [23.40% (11/47) vs. 45.07%(32/71), P=0.017]. For patients with pathological stage ≥pT 3, the positive rate of surgical margins in the study group was significantly lower than that in the control group [30.77%(8/26) vs. 62.16%(23/37), P=0.014]. In the study group, 11 cases of PSMA-PET showed positive lymph nodes before operation, 10 cases were pathologically positive after operation (90.91%). PSMA-PET showed negative lymph nodes in 1 case, which was pathologically positive after operation. In the control group, 26 cases underwent lymph node dissection, and 16 cases (61.54%) were pathologically positive after operation. The preoperative PSA value of 47 cases in the study group was positively correlated with the SUVmax value of prostate cancer tissue ( r=0.579, P<0.01). Conclusions:Preoperative 68Ga-PSMA PET/CT for high-risk prostate cancer patients can guide the surgeon to optimize the surgical plan, reduce the positive rate of resection margins, and effectively remove the metastatic lymph nodes, which will benefit the patients.

Hormone-sensitive prostate cancer with visceral metastasis is a difficulty in clinical diagnosis and treatment. We treated a patient with hormone-sensitive prostate cancer with visceral metastasis and managed it under the multi-disciplinary treatment model (MDT). A 55-year-old man presented to the hospital complaining of increased prostate-specific antigen (PSA) found in the physical examination for 2 days. At admission, the PSA was 389.2ng/ml, and 68Ga-PSMA PET/CT showed metastatic malignant lesions of the prostate, with lymph node metastasis, lumbar vertebral metastases and liver tubercles. Transrectal prostate puncture biopsy: prostate adenocarcinoma, Gleason score of 4+ 5=9. The patient has no history of androgen deprivation therapy (ADT) and diagnosed as metastatic hormone-sensitive prostate cancer (mHSPC). Then the patient received total androgen blockade therapy (CAB regimen). After MDT discussion, metastatic prostate cancer was diagnosed based on the liver histopathology of percutaneous biopsy. After the second MDT discussion, the regimen was changed to abirone plus ADT. After 6 months, the blood PSA was controlled at a level between 0.003 to 0.006 ng/ml, and the testosterone was less than 2.5ng/dl. Re-examination of 68Ga-PSMA PET/CT showed that lower signal of radionuclide in all lesions, especially no more abnormal uptake lesions were identified in the liver.

Objective:To investigate the prognostic factors of renal function after nephron sparing surgery (NSS) in renal tumor patients.Methods:The data of 115 patients who underwent NSS in our hospital from December 2016 to December 2018 were retrospectively analyzed. There were 75 males and 40 females, aged (49.50±12.94) years. The body mass index was (24.59±3.59) kg/m 2. The maximum diameter of the tumor was (3.66±1.32) cm. The R. E.N.A.L. score was (6.43±1.60). Laparoscopic partial nephrectomy was performed in 61 cases and robot-assisted laparoscopic partial nephrectomy was performed in 54 cases, and all of which were successfully completed. Operative time, WIT and postoperative pathological results were recorded. Blood creatinine value, GFR of affected kidney, GFR of healthy kidney, total GFR, GFR preserving rate (the ratio of postoperative GFR to preoperative GFR), functioning parenchymal volume (FPV) of the affected kidneys, and FPV preserving rate of the affected kidneys (the ratio of postoperative FPV and preoperative FPV) were recorded 6 months after surgery. FPV was measured by the ellipsoid approximation on CT images before and after surgery. Paired sample t test was used to compare GFR and FPV before and after surgery. Spearman rank correlation analysis was used to evaluate the correlation between the study factors and GFR preserving rate of the affected kidneys. Multivariate linear regression models were used to analyze independent predictors of renal function of the affected kidneys. Independent sample t test was used for comparison between group of WIT≤25 min and group of WIT>25 min. Results:All of the 115 patients in this study underwent successfully operations, with the median operation time of 135(75-245) min, and WIT(24.57±5.51) min. Postoperative GFR of the affected kidneys(35.50±7.81)ml/(min·1.73 m 2) was significantly different from preoperative GFR( P<0.001). The FPV preserving rate of the affected kidneys was (84.28±4.37)%, which was significantly lower than that preoperative FPV of the affected kidneys ( P<0.001). Spearman rank correlation analysis showed that there was a strong positive correlation between the FPV preserving rate of the affected kidneys and the GFR preserving rate of the affected kidneys ( r=0.802), WIT was negatively correlated with the GFR preserving rate of the affected kidneys ( r=-0.503). Multiple linear regression analysis showed that preoperative GFR of the affected kidneys ( b=-0.150, P=0.008), WIT ( b=-0.443, P<0.001) and the FPV preserving rate of the affected kidneys ( b=1.638, P<0.001) were independent predictors of the GFR preserving rate of the affected kidneys. WIT>25 min group had a significantly lower GFR preserving rate of the affected kidneys than WIT≤25 min group [(68.77±10.88)% vs.(79.34±8.88)%, P<0.001]. Conclusions:In the case of short WIT (<30 min), the reservation of normal renal tissue is the most important variable prognostic factor of renal function after NSS, and short WIT plays a secondary role. Under the premise of complete tumor resection, normal renal tissue should be reserved as much as possible and WIT should be controlled within 25 min.

Objective To compare the diagnostic differences for the detection of bone metastases between 68Ga-PSMA-617 PET/CT and 99Tcm-MDP bone scintigraphy in preliminary diagnosed prostate cancer patients.Methods Seventy-three patients who were diagnosed with prostate cancer by pathology were retrospectively analyzed from June 2017 to February 2018,and they all underwent both ss Ga-PSMA-617 PET/CT and 99Tcm-MDP bone scintigraphy without therapy beforehand.Mean age was 69.1 (range 40-88) years,the mean PSA level was 144.59 (range 5.62-1 260.00) ng/ml,and the Gleason score ranged 6-10.The patients were divided into two groups by whether or not had bone metastases according to the aforementioned two examinations.Both the sensitivity and specificity are calculated.The number of bone metastatic focus of the two examinations were also compared through the Wilcoxon rank testing.Results Thirty-two of 73 patients were diagnosed with bone metastases.68Ga-PSMA-617 PET/CT and 99Tcm-MDP detected 32 and 31 bone metastases,with the sensitivity of 100.0％ (32/32,95 ％ CI 89.1％-100.0％) and 90.6％ (29/32,95％ CI 75.0％-98.0％),the specificity of 100.0％ (41/41,95％ CI 91.4％-100.0％) and 95.12％ (39/41,95％ CI 83.5％-99.4％),and the AUC of 1.000 (95％ CI 0.951-1.00) and 0.929 (95％ CI 0.844-0.976),respectively.There was significant difference in AUC between the two methods(P =0.034).Two examinations exhibited significantly different number of metastatic sites (Z =-2.949,P =0.003).Conclusions 68 Ga-PSMA-617 PET/CT outperform 99Tcm-MDP bone scintigraphy for the detection of bone involvement in prostate cancer patients.It will be an important imaging supplement for prostate cancer patients and play an important role in term of the accurate treatment based on the more accurate evaluation.

Objective To compare the diagnostic efficacy of 68Ga-PSMA-617 PET/CT and multiparameter MRI in the diagnosis of primary tumors of newly diagnosed prostate cancer.and analyze the correlation between SUVmax and clinical parameters of prostate cancer.Methods A retrospective analysis of the clinical data of 104 patients with newly diagnosed prostate cancer who underwent 68Ga-PSMA-617 PET/CT and multi-parametric MRI from June 2017 to April 2018.The final pathological results were used as the gold standard for diagnosis.The age ranged from 42 to 89 years,with an average of (70.4 ± 8.9) years.The median total serum PSA was 18.44 (8.71,48.01)ng/ml.The pathological results were positive in 68 cases and negative in 36 cases.The sensitivity,specificity was calculated,the ROC curve was drawn and AUC value was calculated.The relationship between SUVmax value of prostate cancer and clinical parameters was analyzed.Results The sensitivity of 68Ga-PSMA-617 PET/CT was 95.59％ (65/68) and the specificity was 88.89％ (32/36);the sensitivity of MRI examination was 91.18％ (62/68) and the specificity was 63.89％ (23/36).There were statistical differences between the specificity of the two examination (P =0.012).The ROC curve of 68 Ga-PSMA-617 PET/CT was plotted and the AUC value was 0.954.Among the 104 suspected prostate cancer patients,the median SUVmax of benign prostatic tissue was 3.20(2.83,3.70),and the median SUVmax of prostate cancer tissue was 12.21 (7.48,17.46).Among 68 patients with prostate cancer,there were statistical differences between SUVmax values of prostate cancer tissues with different Gleason scores (P ＜ 0.01),ISUP group (P ＜ 0.01),risk grades (P =0.021),and SUVmax values.There was a positive correlation with Gleason score and ISUP group (r1 =0.7420,P＜0.01;r2 =0.754,P＜0.01).Conclusions The 68Ga-PSMA-617 PET/CT examination had higher diagnostic efficacy than the multiparametric MRI for prostate cancer.The higher the SUVmax value predict the higher grade and higher risk.
