Renal hilar tumors pose significant surgical challenges due to their proximity to major renal vessels and the collecting system. In robot-assisted partial nephrectomy, although both anterior and posterior lip tumors are considered renal hilar tumors, their operative difficulty and complication profiles differ markedly owing to distinct anatomical relationships and vascular adjacency. Anterior lip tumors, often involving tributaries of the renal vein, carry a relatively higher risk of intraoperative and postoperative bleeding. In contrast, posterior lip tumors, closer to the renal artery, are more likely to prolong warm ischemia time, thereby increasing the risk of postoperative renal impairment. Regarding urine leakage, although anterior lip tumors are theoretically closer to the collecting system and may pose a slightly elevated risk, precision reconstruction strategies—such as lip reconstruction based on sinus space anatomy—can effectively mitigate this risk. However, the specific difference in urine leakage risk between anterior and posterior lip tumors warrants further investigation. Both anterior and posterior lip tumors of the kidney can achieve low positive surgical margin rates in experienced centers. Complication risks are affected by multiple factors, including tumor anatomical complexity, warm ischemia time, and surgeon experience. Notably, R.E.N.A.L. score＞8 is associated with significantly increased complication risks. Preoperative meticulous imaging evaluation, selection of an appropriate surgical approach based on tumor location, controlled warm ischemia time, and application of delicate suturing and reconstruction techniques are essential strategies to reduce complications.

Objective:To explore the clinical characteristics and prognostic factors of primary bladder adenocarcinoma（ACB）.Methods:The clinical data of 33 patients with primary ACB who underwent surgical treatment in the Department of Urology of Peking University Third Hospital from July 2003 to January 2024 were retrospectively analyzed. There were 5 females and 28 males，with an average age of（61.3 ± 11.5）years. Twelve patients had comorbidities（6 hypertension，2 coronary heart disease，5 diabetes mellitus，and 3 cerebrovascular diseases）and 12 had a smoking history. The mean body mass index（BMI）was（24.8 ± 3.2）kg/m 2. The maximum tumor diameter measured by enhanced computed tomography（CT）was（29.7 ± 12.7）mm. The preoperative neutrophil-to-lymphocyte ratio（NLR）was 3.4 ± 3.2，and the systemic immune-inflammation index（SII）was（582 ± 496）× 10 9/L.Patients were divided into two groups according to the surgical approach：the radical cystectomy group（ n = 23）and the bladder-sparing group（ n = 10）. For the radical cystectomy group，there were 19 males and 4 females，with a mean age of（59.9 ± 12.6）years. Five patients had comorbidities（3 hypertension，1 coronary heart disease，1 diabetes mellitus，and 2 cerebrovascular diseases）. Eight patients had a smoking history，with a mean BMI of（25.2 ± 3.5）kg/m 2. The maximum tumor diameter was（33.6 ± 10.9）mm，the preoperative NLR was 3.5 ± 3.5，and the SII was（618 ± 558）× 10 9/L. For the bladder-sparing group，there were 9 males and 1 female，with a mean age of（64.5 ± 8.2）years. Seven patients had comorbidities（3 hypertension，1 coronary heart disease，4 diabetes mellitus，and 1 cerebrovascular diseases）. Four patients had a smoking history，with a mean BMI of（23.5 ± 2.3）kg/m 2. The maximum tumor diameter was（20.7 ± 12.5）mm，the preoperative NLR was 3.1 ± 2.2，and the SII was（501 ± 323）× 10 9/L. Statistically significant differences were observed between the two groups in terms of comorbidities（ P = 0.008）and maximum tumor diameter（ P = 0.006），while no significant differences were found in other data（ P > 0.05）. The Kaplan-Meier survival curve was drawn，and Cox regression was used to analyze the prognostic factors of progression-free survival（PFS）and overall survival（OS）of patients. Results:Among the 33 patients，low-grade adenocarcinoma and high-grade adenocarcinoma accounted for 60.6% and 39.4% respectively according to the postoperative pathology，and 3 patients had positive surgical margins. There were 22 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，and 1 case of distant metastasis. The patients in tumor stages Ⅰ—Ⅳ were 9 cases（27.3%），8 cases（24.2%），7 cases（21.2%），and 9 cases（27.3%）respectively. Nine patients received postoperative adjuvant therapy，including 6 with adjuvant chemotherapy，2 with adjuvant chemotherapy combined with radiotherapy，and 1 with adjuvant immunotherapy. In the radical cystectomy group（ n = 23），there were 13 cases of low-grade and 10 cases of high-grade pathological grading，2 cases with positive margins，19 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，1 case of distant metastasis，and 5 patients received adjuvant therapy（4 cases of adjuvant chemotherapy，and 1 case of adjuvant immunotherapy）. In the bladder-sparing group（ n = 10），there were 7 cases of low-grade，3 cases of high-grade pathological grading，1 case with positive margins，3 cases of muscle-invasive bladder adenocarcinoma，zero lymph node or distant metastasis，and 4 patients received adjuvant therapy（2 cases of adjuvant chemotherapy，and 2 cases of combined adjuvant chemotherapy and radiotherapy）. A statistically significant difference was found in the proportion of muscle-invasive bladder adenocarcinoma between the two groups（ P = 0.006），while no significant differences were observed in other data（ P > 0.05）.The median follow-up duration of the patients was 28.0 months，the median PFS was 86.0 months，and the median OS was 90.0 months. The 2-year PFS and OS were 65.4% and 73.1% respectively. The 5-year PFS and OS were 54.2% and 56.5% respectively. The Kaplan-Meier survival analysis showed that there were no significant differences in PFS（ P = 0.777）and OS（ P = 0.585）between the radical cystectomy group and the bladder-preserving group. Female（ P = 0.011），BMI < 25 kg/m2（ P = 0.038），and positive surgical margins（ P < 0.01）were associated with poorer PFS. Aged ≥ 70 years（ P = 0.003），lymph node metastasis（ P = 0.041），and positive surgical margins（ P = 0.025）were associated with poorer OS，and patients in the adjuvant therapy group had better OS（ P = 0.005）. Multivariate Cox regression analysis indicated that positive surgical margins（HR 10.2， P = 0.012）were an independent impact factor for PFS，and positive surgical margins（HR 39.8， P = 0.001）and adjuvant therapy（HR 0.12， P = 0.021）were independent impact factors for OS. Conclusions:Positive surgical margins and adjuvant therapy are independent impact factors for the prognosis of patients with primary ACB.

Objective:To evaluate the safety and oncological outcomes of robot-assisted laparoscopic inferior vena cava(IVC)segmental resection in renal tumor with IVC tumor thrombus(IVCTT).Methods:Clinical data from renal tumor patients undergoing robot-assisted laparoscopic IVC segmental resection at Peking University Third Hospital from Jan.2021 to Feb.2025 were retrospectively analyzed.Data collection included baseline demographics,tumor characteristics,perioperative parameters,and follow-up outcomes.Surgical records and pathological reports were retrieved from the electronic medical record system.Continuous variables were presented as median(P25,P75),and categorical variables as frequency(percentage).Results:Forty-four patients were enrolled.The cohort comprised 31 malesand 13 females,with a median age of 62(55,68)years.Right-sided tumors were observed in 39 cases and left-sided in 5 cases.Median tumor diameter was 8.1(6.1,10.1)cm.Mayo classifications included grade Ⅱ(n=37),Ⅲ(n=6),and Ⅳ(n=1).Neoadjuvant therapy was administered to 23 patients.Seventeen patients were complicated by IVC bland thrombus.Median operative time was 224.0(167.3,303.8)min,with intraoperative blood loss of 500.0(300.0,850.0)mL.Transfusion was administered to 19 patients,with a median blood transfusion of 800.0(400.0,1 200.0)mL.Postoperative complica-tions occurred in 25 cases(56.8％),classified as Clavien-Dindo grade Ⅰ(n=8)and grade Ⅱ(n=17).Procedure-specific complications included deep vein thrombosis(n=6),transfusion-requiring ane-mia(n=5),lower extremity edema(n=2),and pulmonary embolism(n=2),with no procedure-related mortality.Median postoperative serum creatinine was 116.0(86.5,157.5)μmnol/L.Pathological examination identified clear cell renal cell carcinoma as the predominant subtype,observed in 34 cases(77.3％).Pathological staging revealed T3b(n=12),T3c(n=29),and T4(n=3)disease,with nodal involvement(N1)in 8 cases and distant metastasis(M1)in 17.At a median follow-up of 10 months(range:1-49 months),cancer-specific mortality occurred in 3 patients,while 1 succumbed to other causes.Disease progression included pulmonary metastasis(n=5),hepatic metastasis(n=4),and local recurrence(n=4).Adjuvant therapy regimens comprised targeted-immunotherapy combina-tions(n=9)and targeted monotherapy(n=18).Conclusion:Robot-assisted laparoscopic I VC seg-mental resection achieves precise thrombus removal with confirmed short-term efficacy in renal tumor with IVCTT,though vigilance against vascular complications remains critical.

Objective:To review the clinicopathological features of TFE3-rearranged renal cell carcino-ma(TFE3-RCC)with venous tumor thrombus(VT)(TFE3-VT),to explore treatment strategies and to prognostic characteristics,and to provide diagnostic and therapeutic references for TFE3-VT patients.Methods:Patients who underwent surgery at Department of Urology,Peking University Third Hospital from January 2013 to January 2024 were enrolled,including three cohorts:Pathologically confirmed TFE3-VT patients,TFE3-RCC patients without VT(TFE3-non-VT),and non-TFE3-rearranged renal cell carcinoma patients with VT(non-TFE3-VT).Clinical history,imaging data,pathological data,and follow-up records were collected.Primary and secondary endpoints were progression-free survival(PFS)and overall survival(OS),respectively.(1)Baseline characteristics were compared between the TFE3-VT and TFE3-non-VT patients.Normally distributed continuous variables were expressed as mean±SD and compared using Student's t-test;non-normally distributed variables were expressed as M(P25,P75)and analyzed with Mann-Whitney U test;categorical variables were described as frequency and percentage[n(％)]and compared by x2 test or Fisher's exact test.(2)Clinical history,radiological presenta-tions,surgical data,and histopathological features of the TFE3-VT patients were comprehensively charac-terized.(3)Survival analysis was performed for the TFE3-VT patients.Follow-up data of the TFE3-VT patients were described in detail,and their survival outcomes were compared with the TFE3-non-VT and non-TFE3-VT patients.When compared with the TFE3-non-VT counterparts,Kaplan-Meier method was used to generate PFS and OS curves among:(1)the TFE3-RCC patients across clinical stages Ⅰ-Ⅳ;(2)TFE3-VT versus TFE3-non-VT cohorts;(3)stage Ⅲ subgroups of the TFE3-VT and TFE3-non-VT patients.Intergroup survival differences were statistically evaluated using Log-rank tests.For comparisons with the non-TFE3-VT patients,a 1∶1 propensity score matching(PSM)was implemented to balance baseline characteristics between the two cohorts.Post-matching Kaplan-Meier curves were generated to compare PFS and OS between the matched groups,with Log-rank tests employed to determine statistical significance of survival disparities.All statistical analyses were conducted with R software(v 4.2.3),and two-tailed P＜0.05 was considered statistically significant.Results:The study included 45 TFE3-RCC patients:13 TFE3-VT and 32 TFE3-non-VT cases.Additionally,523 non-TFE3-VT patients were enrolled.Among the 13 TFE3-VT patients,9 were female(69.2％)and 4 male(30.8％),with a mean age of(37.9±14.4)years,mean BMI of(22.2±3.5)kg/m2,median age-adjusted Charlson comorbidity index(aCCI)of 1.0(0.0,1.0),and preoperative creatinine level of(75.3±15.9)μmol/L;tumors were located in the left kidney in 7 patients(53.8％)and right kidney in 6(46.2％);preoperative distant metastasis(M1 stage)was present in 6 patients(46.2％),while 7(53.8％)showed no metastasis;VT distribution by Mayo level comprised 7 cases(53.8％)at level 0,1 case each at levels Ⅰ and Ⅳ(7.7％respectively),and 2 cases each at levels Ⅱ and Ⅲ(15.4％respectively);surgical approaches comprised open surgery(n=2,15.4％),laparoscopic surgery(n=6,46.1％),and robot-assisted laparoscopic surgery(n=5,38.5％);mean operative time was(273±79)min,and intraoperative blood loss was(722±570)mL;mean maximum tumor diameter was(10.8±2.4)cm.All the 13 patients underwent TFE3 protein immunohistochemistry(IHC)staining,with 7 confirmed by fluorescence in situ hybridization(FISH).Tumor recurrence or metastasis occurred in 11 patients(84.6％),and 9(69.2％)patients died during follow-up.Median PFS was 4 months(1 year PFS rate:31％),and median OS was 13 months(1 year OS rate:54％).Survival analysis of 45 TFE3-RCC pa-tients revealed statistically significant differences in PFS and OS across all the clinical stages(P＜0.001).The TFE3-VT patients exhibited significantly worse PFS and OS than the TFE3-non-VT patients(P＜0.001),with persistent significance in stage Ⅲ subgroup analysis(P＜0.05).After PSM,TFE3-VT pa-tients showed significantly inferior PFS compared with non-TFE3-VT(P=0.01),though no significant difference was shown between the OS curves(P=0.11).Conclusion:TFE3-VT predominantly occurs in young females with frequent preoperative metastases.Strongly-positive staining of TFE3 protein in IHC stai-ning and red-green split signals in FISH tests are reliable diagnostic markers.TFE3-VT patients exhibit in-ferior survival compared with TFE3-non-VT patients and earlier progression than non-TFE3-VT patients.

Objective:To explore the impact of DRG payment reform on high-ratio cases and their hospitalization expenses, so as to provide references for deepening the reform of the medical insurance payment system.Methods:Data were collected from inpatient medical record home pages within 2019 to 2023 in a reform pilot hospital in Wuhan. All cases were grouped by the CHS-DRG grouper. The high-ratio cases were identified as hospitalization expenses exceeding 2.5 times the standard expenses. Interrupted time series model was used to analyse the impact of DRG payment reform on the proportion of high-rate cases and their hospitalization expenses. The period from January 2019 to December 2020 was the stage before the reform, and the period from January 2021 to December 2023 was the stage after the reform.Results:This study included 1 364 711 grouped cases, among which there were 159 506 high-ratio cases(78 679 cases before the reform and 80 827 cases after the reform). After the implementation of DRG payment, the proportion of high-ratio cases was decreased from 17.29% to 8.89%. The average DRG weight increased from 0.94 before the reform to 1.12 after the reform, and the average total hospitalization cost increased from 45 677.18 yuan to 52 179.32 yuan. Results from interrupted time series model showed that the proportion of high-ratio cases appear a downward trend after the reform( P=0.008). The total hospitalization cost showed an upward trend both before and after the reform( P<0.05), but the growth trend slowed down after the reform. The diagnosis cost exhibited an upward trend both before and after the reform( P<0.05), but there was a significant immediate decrease immediately after the implementation of the reform( P=0.016); The treatment cost showed an upward trend after the reform( P<0.001); The consumable cost had an upward trend before the reform( P=0.007), but the change trend after the reform was not statistically significant( P=0.544). In addition, the treatment expenses of the surgical group and the internal medical group both showed a significant upward trend after the reform( P<0.001); The consumable cost of the procedural group and the diagnosis cost of the internal medicine group both decreased immediately after the reform( P<0.05). Conclusions:DRG payment helps reduce the high-ratio cases and has a certain optimizing effec on their structure of hospitalization cost.

A 34-year-old male patient was admitted to the hospital on October 6, 2023 due to fall from a high place. Physical examination showed blood pressure 96/53 mmHg (1 mmHg=0.133 kPa), heart rate of 105 beats/min, slight bulge in the right kidney area, and positive percussion pain in the right kidney area. CT examination showed complete rupture of the lower pole of the right kidney, thrombosis of the right renal vein, and contusion and laceration of the right posterior lobe of the liver. According to the American Association for the Surgery of Trauma renal injury classification, he was diagnosed as grade Ⅳ renal rupture. After blood transfusion and fluid infusion, vital signs were stable. Laparoscopic nephrectomy plus renal vein thrombectomy plus liver rupture repair were performed. The operation took 90 minutes, and about 300 ml of blood clots and fresh blood were aspirated during the operation. The patient's vital signs were stable after the operation, and he could get out of bed 3 days after the operation. CT reexamination 1 month after the operation showed right kidney resected and the liver healed well. This operation is feasible if the patient's vital signs are stable, with the advantages of small surgical incision, short operation time, less bleeding, fast postoperative recovery and good surgical effect.

OBJECTIVE: To investigate the safety and prognostic factors influencing the treatment of upper urinary tract urothelial carcinoma (UTUC) combined with bladder cancer (BCa) by laparoscopic simultaneous radical cystectomy and nephroureterectomy (RCNU). METHODS: The clinical data of patients admitted to Peking University Third Hospital for laparoscopic RCNU surgery from January 2009 to September 2023 were analyzed retrospectively. Based on the same gender, age (±5 years), history of uroepithelial tumors, underlying diseases, T-stage, N-stage, M-stage, American Society of Anesthesiologists (ASA) score, Charlson comorbidity index, and body mass index (BMI) (±5), 34 patients with RCNU were matched 1 ∶1 with patients with bladder cancer who underwent laparoscopic radical cystectomy (RC) alone. Kaplan-Meier survival analysis was used to calculate patient survival, and Cox proportional regression risk model was used to analyze clinical factors affecting prognosis. RESULTS: Of the 68 patients enrolled, the follow-up rate was 100% with a median follow-up time of 27.0 (11.7, 60.2) months. Comparison of intraoperative conditions (including operation time, estimated intraoperative bleeding, intra-operative blood transfusion, etc.) between the two groups of patients showed no significant difference (P>0.05). Comparison of preoperative creatinine and postoperative creatinine between the two groups of patients showed significant differences (P < 0.05). The perioperative Clavien grade Ⅲ-Ⅳ complication rates were 2.9% (1/34) in the RC group and 5.9% (2/34) in the RCNU group. There was no significant difference in terms of perioperative complications between the two groups. Overall survival was significantly lower in the patients receiving RCNU compared with the matched group receiving RC alone (P < 0.05). Cox regression analysis suggested that two factors, high N stage and high postoperative creatinine, were independent risk factors affecting the prognosis of patients in the 2 groups (P < 0.05). CONCLUSION The overall survival prognosis of patients undergoing RCNU surgery was worse compared with laparoscopic RC surgery alone during the same period. There was no clinically significant difference between the two groups in terms of operation time, intraoperative bleeding, and perioperative complications, and there were clinically significant differences in preoperative renal function and post-operative renal function.
