Methods We collected the clinical data of 132 patients who were diagnosed with upper urinary tract obstruction by 64-slice spiral CT urography between December 2009 and January 2011. We analyzed the imaging features and compared them with surgical and pathological results. Results Confirmed by surgical and pathological results, 132 patients included 31 cases of urethral stone, 51 cases of congenital variant and malformation, 16 cases of ureteral infection, 29 cases of tumors in urinary tract, 3 cases of extraneous compression, and 2 cases of cysts next to the renal pelvis. CT diagnosis for all cases were basically in line with clinical and pathological results. Conclusion CT urography is an extremely valuable imaging method to diagnose the diseases of urinary system. It can display lesions broadly and reveal their inner and peripheral circumstances clearly, thus can help us determine the reasons and natures of the lesions precisely.

Methods The complete CT image data of 22 patients with tuberculotic peritonitis confirmed by surgical, pathologically, or therapeutic procedures from October 2009 to July 2010 were retrospectively analyzed. The changes of lymph nodes, ascites, thickened peritoneum, mesentery and greater omentum were observed. Results In 22 patients, enlargement and rim enhancement of lymph nodes were found in 12; ascites with CT value of 20-28 HU was in 15, of whom 12 had small or middle amount of effusion which located in mesentery or abdominal cavity; thickened parietal peritoneum was in 16, including smooth peritoneum in 14 and evident enhancement in 10; thickened greater omeutum was in 15, including cake-like thickening in 2, filth-like thickening in 9 and tuber-like thickening in 4; thickened mesentery was in 18, including intestinal loop adhesion in 3.A total of 13 patients were combined with other tuberculosis. Conclusion CT scan is very important in diagnosing and differentially diagnosing tuberculous perinitis.
Objective To explore the value of multidetector row helical CT （MDCT） in the diagnosis of lymph node metastasis in adenocarcinoma of esophaogastric junction （AEG）， and to study the pattern of lymph node metastasis of it. Methods The MDCT images of 60 patients with AEG who underwent operation in our hospital from Jan. 2011to Oct. 2012 were collected， in order to explore the value of MDCT in the diagnosis of lymph node metastasis in AEG， and to study the pattern of lymph node metastasis of it. Results With diameter upper 8 mm and the difference of the mean value of enhanced degree upper 70 Hu as the standard of lymph node metastasis， the Kappa value （0.819 and 0.718），sensitivity （83.1% and 91.8%）， and specificity （78.9% and 83.5%） were all optimal. The lymph node metastasis rate was significantly higher in serosa invasion group than those of non-invasion group （P＜0.05）. The metastatic area of lymphnodes mainly concentrated around cardia （No. 7， 8， and 9 group）， lesser curvature of the stomach， celiac axis， and hepato-gastric ligament （No. 10， 11， 12， and 14 group） with the metastasis rate of 83.8% and 82.3%， respectively. Conclusion MDCT is useful to confirm the features， location， and rules of lymph node metastasis in patients with AEG， which is helpful in accurately cleaning the lymph nodes.
Objective To evaluate the clinical value of multi-detector row helical CT (MDCT) in Diagnosing the TN staging and typing of adenocarcinoma of esophagogastric junction. Methods From January 2008 to June 2011，149 consecutive cases with AEG confirmed surgery were examined by using MDCT scanner before surgery in West China Hospital，pathologic and operative finding diagnosis were correlated with that results of MDCT . Results The accuracies of MDCT for the T1, T2, T3, and T4 staging was 97.3%，91.3%，84.5%， and 89.3%，respectively， and for the typing of Ⅰ,Ⅱ, andⅢwas 84.6%, 63.8%, and 79.2%，respectively. The accuracies of MDCT to judge the metastasis of lymph node was 88.6%（132/149）. The feature of metastasis of lymph node with circular and fusion，significantly and obviously enhanced，ring and heterogeneous enhanced, which the positive rate of pathological metastasis was higher (P=0.000). Conclusions MDCT is an excellent diagnostic tool for the diagnosis of the TN staging and typing of AEG, which is useful for the selection of the surgical procedure and decision operation path.
Objective To investigate the clinical efficacy of endoscopy-assisted anterior cervical discectomy and fusion for cervical spondylosis. Methods The clinical data of patients treated with water medium endoscopy-assisted anterior cervical discectomy and fusion for cervical spondylosis at Mianyang Orthopedic Hospital between September 2021 and September 2023 were retrospectively collected. The surgical efficacy and nerve injury recovery were evaluated based on the Neck Disabilitv Index (NDI), Japanese Orthopaedic Association (JOA) score, improvement rate of JOA score, Cobb angle and height changes of the affected intervertebral space before surgery and at the last follow-up, as well as the occurrence of surgical complications. Results A total of 29 patients were included, including 18 males and 11 females. The average age was (52.34±8.96) years, and the average duration of illness was (17.31±6.60) months. The average follow-up time was (11.69±3.41) months. At the last follow-up, the patients’ NDI (3.55±3.09 vs. 17.28±5.51), Cobb angle [(15.25±4.83) vs. (−1.34±7.50)°], intervertebral height [(8.04±0.82) vs. (4.67±0.95) mm], and JOA score (15.90±1.11 vs. 11.17±1.65) improved compared to preoperative levels (P<0.05). The JOA score improvement rate assessment showed that 16 cases were excellent, 11 cases were fine, 2 cases were moderate, and the excellent and fine rate was 93.10%. All patients did not experience serious complications after surgery. Conclusion Water medium endoscopy-assisted anterior cervical discectomy and fusion for cervical spondylosis has good clinical efficacy and safety.
