Percutaneous nephrolithotomy(PCNL) has always been the first-line minimally invasive treatment for staghorn kidney stones, with high surgical efficiency and first-stage stone free rate. However, due to the complexity of stones and the difficulty of surgery, serious complications such as postoperative bleeding, infection, and renal function damage often occur. Needle-perc assisted endoscopic surgery(NAES) surgery, also known as needle-perc assisted endoscopic surgery, is an innovative model based on needle-perc proposed by our center. The S+ N mode is standard tract PCNL combined with needle-perc, which not only improves the efficiency and stone free rate, but also reduces the number of tracts, effectively protecting renal function and reducing complications. This article reports a case of complete staghorn kidney stones that were completely removed by NAES surgery in one stage, with no complications after surgery and the patient recovering quickly and being discharged from the hospital.

Objective To evaluate the application value of artificial intelligence mixed reality(AI-MR)technology in the planning of ultrasound-guided percutaneous nephrolithotomy(PCNL)for special types of complex upper urinary stones.Methods The prospective single-center,single-arm clinical study involved 15 patients with complex upper urinary stones undergoing ultrasound-guided PCNL during Aug.2022 and May 2023,including 9 male and 6 female,3 cases of pelvic ectopic kidney stones,5 cases of horseshoe kidney stones,3 cases of renal stones combined with spinal deformity,and 4 cases of transplant kidney stones.Based on preoperative computed tomography urography(CTU)data,digital three-dimensional reconstruction was performed,and AI-MR was used to project surgery-related three-dimensional images in real space to obtain"perspective"information of the surgical area.This facilitated preoperative design and planning,including target calyx,number of channels,and auxiliary measures.The compliance of target calyx and number of channels,stone clearance rate,total operation time,time required to establish the percutaneous renal channel,decrease in hemoglobin level,surgical complications,and postoperative hospital stay were analyzed.Results All 15 patients underwent preoperative planning using AI-MR and successfully completed one-stage ultrasound-guided PCNL.Based on the preoperative planning,we utilized S-PCNL alone or combined with Needle-perc or antegrade/retrograde FURS/RIRS.Among all patients,4 underwent single-channel S-PCNL,3 multi-channel S-PCNL,and 8 S-PCNL combined with Needle-perc or FURS.The compliance of target calyx and number of channels was 86.7％,the one-stage stone clearance rate was 80.0％,the average time for establishing the channel was(2.3±0.3)minutes,the average total operation time was(61.5±12.2)minutes,the mean decrease in hemoglobin level was(9.6±1.2)g/L,and the average postoperative hospital stay was(4.6±0.5)days.There were no Clavien-Dindo grade ≥ Ⅱ complications,such as blood transfusion,organ injury,or urosepsis.Conclusion Before surgery,AI-MR can be used to quantitatively analyze imaging data for patients with special types of complex upper urinary stones,which can achieve three-dimensional fluoroscopy effects,formulate surgical plans,optimize puncture paths,effectively avoid the risk of damage to surrounding organs,reduce complications,shorten treatment cycle and improve the first-stage stone clearance rate.

Objective:To explore the clinical features of immunocompetent primary central nervous system lymphoma (PCNSL) and influencing factors for prognosis of immunocompetent patients with PCNSL.Methods:A retrospective analysis was performed; 69 immunocompetent patients with PCNSL confirmed by pathology in First Medical Center of PLA General Hospital from January 2016 to January 2024 were enrolled; initial symptoms, Eastern Cooperative Oncology Group (ECOG) score, and results of laboratory and pathological examinations in these patients were collected. Patients were divided into biopsy confirmed group ( n=43) and lesion resection confirmed group ( n=26) according to different diagnostic methods; patients were also divided into chemotherapy group ( n=48), chemotherapy+radiotherapy group ( n=9) and surgical resection group ( n=12) according to different treatment methods. Clinical outcomes of these patients in different groups at the end of follow-up were compared, and the influencing factors for short-term prognosis (6 months after treatment) were identified. All patients were followed up for 12.80 (6.00, 36.40) months. The short-term prognosis was evaluated by modified Rankin scale (mRS) 6 months after treatment (mRS scores of 0-2: good prognosis; mRS scores of 3-6: poor prognosis). Overall survival (OS) was recorded at the end of follow-up. Results:Among the 69 immunocompetent patients with PCNSL, 37 were males and 32 were females; median onset age was 59 years, ranged 24-83 years. Focal neurologic deficits of different degrees (34/69, limb weakness, sensory disturbances, ataxia, or eye involvement) were the most common initial symptoms, followed by headache (14/69), dizziness (10/69), cognitive dysfunction (9/69), epilepsy (1/69) and psychiatric disorders (1/69). Forty-five patients underwent cerebrospinal fluid examination: 17 had cerebrospinal fluid pressure≥200 mmH 2O (1 mmH 2O=9.8 Pa); 10 had increased white blood cell count (>10×10 6/L), reaching to (16.5[11.0, 20.0])×10 6/L; 32 had increased protein level, reaching to 758.10 (547.83, 948.13) mg/L. Cerebrospinal fluid cytology was performed in 15 patients, and tumor cells were found in only 1 patient. Cranial MRI showed that intracranial solitary lesions were more common (60.87%, 42/69), and most lesions were at the basal ganglia region (40.58%, 28/69). PET/CT showed a obviously higher metabolism of the lesions (97.06, 33/34), with maximum standardized uptake of 22.9 (13.9, 30.55) g/mL. All patients had diffuse large B-cell lymphoma (DLBCL). By the end of follow-up, 28 patients died. Logistic regression analysis showed that ECOG score≥2 ( OR=9.210, 95% CI: 2.558-32.896, P=0.001) and positive MYC ( OR=0.088, 95% CI: 0.008-0.973, P=0.047) were independent risk factors for poor short-term prognosis. Cox proportional hazard regression model analysis showed that ECOG score≥2 ( HR=5.135, 95% CI: 2.230-11.827, P<0.001), positive B-cell lymphoma 6 (BCL-6, HR=0.226, 95% CI: 0.079-0.649, P=0.006) and chemotherapy or chemotherapy+radiotherapy ( HR=0.392, 95% CI: 0.157-0.980, P=0.045) were independent prognostic factors for OS. Conclusions:In immunocompetent patients with PCNSL, focal neurological deficits are more common at the onset, and fever is rare. Patients with ECOG score≥2 are more likely to have poor short-term prognosis and short OS. MYC-positive patients will have a better short-term prognosis; BCL-6 positive patients and patients treated with chemotherapy or chemotherapy+radiotherapy will have longer OS.

Objective:To summarize the clinical characteristics and therapeutic efficacy of central nervous system (CNS) aspergillosis.Methods:The clinical manifestations, laboratory examination, neuroimaging features, treatment and prognosis of 37 cases of CNS aspergillosis diagnosed and treated in the First Medical Center of People′s Liberation Army General Hospital from January 2000 to January 2021 were retrospectively analyzed. According to the correlation between intracranial lesions and paranasal sinus lesions, they were divided into two groups: rhino-cerebral aspergillosis (RA, n=21) group and cerebral aspergillosis (CA, n=16) group. Results:Only 16.2% (6/37) of CNS aspergillosis patients had a clear background of immunosuppression, but 35.1% (13/37) were complicated with diabetes. The most common clinical manifestations were headache (73.0%, 27/37), cranial nerve involvement (59.5%, 22/37) and fever (37.8%, 14/37). Cerebrospinal fluid characteristics included increased pressure (53.8%, 14/26), increased white blood cell count (46.7%, 14/30), decreased glucose (30.0%, 9/30), increased protein (70.0%, 21/30), and high positive results of the metagenomic next-generation sequencing (mNGS) of pathogenic microorganism (7/10). Cranial magnetic resonance imaging showed that commonly involved sites were sinus, orbital apex, posterior orbit, cavernous sinus (43.2%, 16/37) and cerebral lobes (27.0%, 10/37). Treatment options included antifungal drugs alone (64.9%, 24/37), combination of drugs and surgery (27.0%, 10/37) and surgery alone (8.1%, 3/37). Compared with the CA group, RA group had fewer males [47.6% (10/21) vs 14/16, χ2=6.34, P=0.012] and older age [(54.2±19.4) years vs (38.4±18.4) years, t=2.50, P=0.017], and was more prone to headache [85.7% (18/21) vs 9/16, χ2=4.00, P=0.046) and cranial nerve involvement [81.0% (17/21) vs 5/16, χ 2=9.31, P=0.006]. The misdiagnosis rate of these patients in the early stage was 73.0% (27/37). A total of 29 patients (85.3%, 29/34) were treated with voriconazole successively, and the course of treatment was 3.0 (0.5, 10.4) months. Compared with salvage therapy, the mortality of primary therapy was lower (4/17 vs 9/12, χ2=7.54, P=0.006). All patients were followed up to December 2021, and 17 patients died, with a mortality rate of 45.9% (17/37). Conclusions:CNS aspergillosis may have no definite immunosuppressive background. Some of CNS aspergillosis patients are complicated with diabetes, and the clinical manifestations of the disease lack specificity, with high misdiagnosis rate in the early stage, no inflammatory changes in cerebrospinal fluid, and high positive rate of mNGS for pathogenic microorganism. Early and long-term application of voriconazole can significantly reduce the mortality rate.

【Objective】 To determine the reference range of thromboelastogram(TEG) and establish a TEG feature for local population by measuring TEG parameters in healthy adults in Shenzhen comparing the difference between gender and age, and analyzing the reference data provided by reagent manufacturer. 【Methods】 A total of 916 healthy adults, aged between 19 to 59, who did their regular health checks in our hospital from September 2020 to August 2021 were selected. The TEG(from Lepu Medical Technology Co., Ltd.) was performed, and the clot reaction time(R), clot formation time(K), coagulation angle(α-Angle), maximum amplitude(MA), coagulation index(CI), fibrinolysis index LY30 and the estimated percent lysis (EPL) were analyzed. 【Results】 The reference ranges of TEG parameters, including R, K, α-Angle, MA, CI, LY30 and EPL, of 916 healthy adults from Shenzhen were 3.25~8.19 min, 0.66~3.18min, 47.70~76.56deg, 50.05~72.91mm, -4.3~3.4, 0~2.2% and 0~3%, respectively. The value of α-Angle, CI, K, LY30, MA and R didn’t all meet the given range provided by the manufacturer; some were exceeding and some inferior to. A total of 227 out of 916 individuals presented abnormal results, relative to the references, in at least one parameter, and 78 were diagnosed of abnormal coagulation based on the given reference range, with a specificity of 75.2%. 【Conclusion】 The reference range of TEG parameters of Shenzhen locals is significantly different from that provided by manufacturers. And it is imperative for local TEG laboratories to establish their own reference ranges according to age and gender groups based on local population characteristics.

Objective:To investigate the efficacy of transurethral resection of the prostate (TURP) versus plasmakinetic resection of the prostate (PKRP) in the treatment of patients with giant benign prostatic hyperplasia and their effects on erectile function. Methods:A total of 100 patients with GBPH who received treatment in the General Hospital of Taiyuan Iron and Steel (Group) Co., Ltd., from February 2017 to January 2020 were included in this study. They were randomly assigned to undergo either PKRP (PKRP group, n = 50) or TURP (TURP group, n = 50). Perioperative indicators were recorded. Urodynamic indicators and serum indicators pre- and post-operation were compared between the two groups. Erectile function and quality of life were compared between the two groups. The incidences of postoperative complications such as erectile dysfunction, urinary incontinence and urethral stricture were calculated. Results:Operative time, hospital stay, catheter indwelling time, and intraoperative blood loss in the PKRP group were significantly shorter and less than those in the TURP group ( t = 14.35, 8.74, 6.20, 8.34, all P < 0.001). There were no significant differences in residual urine volume and maximum urine flow rate measured before surgery between the two groups ( t = 0.59, 0.73, both P > 0.05). After surgery, residual urine volume decreased and maximum urine flow rate increased in each group. Residual urine volume was significantly lower and maximum urine flow rate was significantly higher in the PKRP group compared with the TURP group ( t = 19.85, 11.67, both P < 0.001). Before surgery, there were no significant differences in serum prostate-specific antigen and free prostate-specific antigen between the two groups ( t = 0.43, 0.33, both P > 0.05). After surgery, both serum prostate-specific antigen and free prostate-specific antigen decreased in each group, and both serum prostate-specific antigen and free prostate-specific antigen were significantly lower in the PKRP group than those in the TURP group ( t = 16.01, 5.09, both P < 0.001). Before surgery, there were no significant differences in quality of life (QOL) score and International Index of Erectile Function (IIEF) score between the two groups ( t = 0.62, 0.63, both P > 0.05). After surgery, IIEF score was increased and QOL score was decreased in each group. After surgery, IIEF score in the PKRP group was significantly higher than that in the TURP group [(25.06 ± 3.61) points vs. (21.52 ± 3.05) points, t = 5.29, P < 0.001], and QOL score in the PKRP group was significantly lower than that in the TURP group [(1.05 ± 0.18) points vs. (1.58 ± 0.29) points, t = 5.29, 10.98, both P < 0.001]. The incidence of complications in the PKRP group was significantly lower than that in the TURP group ( χ2 = 5.98, P < 0.05). Conclusion:This study investigated the effects of TURP versus PKRP on giant benign prostatic hyperplasia from the aspects including erectile function, QOL, and perioperative indicators. This study is of certain innovation. Findings from this study confirm that both PKRP and TURP can improve erectile function, serum indicators, and urodynamic indicators in patients with giant benign prostatic hyperplasia. PKRP is preferred because it is less invasive, results in better improvements in erectile function, serum indicators, and urodynamic indicators, and has fewer complications than TURP.

OBJECTIVE: To evaluate the efficacy of lumbar transforaminal epidural block (LTEB) for treatment of low back pain with radicular pain. METHODS: We retrospectively analyzed the clinical data of 78 patients with low back pain and radicular pain admitted to the Department of Orthopedics of Beijing Chuiyangliu Hospital from March, 2017 to April, 2019. Thirty-three of the patients received treatment with LTEB (LTEB group), and 45 received comprehensive conservative treatment including traction, massage, acupuncture and physiotherapy (control group). The demographic and clinical data of the two groups were compared. The patients were followed up for 3 to 24 months, and numerical rating scale (NRS) and Oswestry disability index (ODI) scores of the patients were evaluated before the treatment and at 2 weeks, 1 month and 3 months after discharge to assess the efficacy of the treatment. RESULTS: The mean operation time of LTEB was 25.7 7.5 min (15-45 min). After the operation, 5 patients developed weakness of the lower limbs but all recovered within 24-72 h. The patients receiving LTEB all showed significantly decreased NRS scores for low back and radicular pain and ODI scores after the operation ( CONCLUSIONS As a minimally invasive approach, LTEB is effective for treatment of low back pain with radicular pain and can produce good short-term effects of pain relief and functional improvement.
