ABSTRACT

Objective:To investigate the risk factors of urethrovesical anastomotic leakage after laparoscopic radical prostatectomy.Methods:The clinical data of 292 patients who underwent laparoscopic radical prostatectomy in the Tenth People's Hospital Affiliated to Tongji University from January to December 2021 were retrospectively analyzed. According to whether there was anastomotic leakage, the patients were divided into leakage group (27 cases) and non-leakage group (265 cases). There were no significant differences in age [(71.5±6.5) years vs. (70.2±6.4) years], body mass index [(24.5±3.6) kg/m 2 vs. (24.2±3.0) kg/m 2], prostate volume[40(27.3, 63.2)ml vs. 38(28.1, 56.2)ml], Gleason score, clinical stage, and risk classification between the leakage group and the non-leakage group ( P>0.05), but the total prostate-specific antigen in the leakage group was significantly higher than that in the non-leakage group[20.0 (9.6, 79.0) ng/ml vs. 13.7 (8.5, 25.0) ng/ml, P=0.049]. Propensity score matching (PSM) was used to match the above indicators between the leakage group and the non-leakage group as 1∶1, so that the baseline of the two groups was balanced. The perioperative indicators of the matched two groups of patients were compared and analyzed. Statistically significant indicators were selected and included in univariate and multivariate logistic regression to analyze the risk factors of anastomotic leakage after radical prostatectomy. Finally, the receiver operating characteristic (ROC) curve was drawn, and the area under the curve (AUC) was calculated. The accuracy of each factor in predicting urine leakage was obtained. Results:After PSM, 24 cases were successfully matched. The leakage group had shorter membranous urethral length (MUL) [(15.5±2.2)mm vs. (17.5±1.5)mm, P<0.001], thinner membranous urethral wall thickness (UWT) [(9.5±1.9)mm vs. (10.6±1.5)mm, P=0.024], longer anastomotic time of urethrovesical neck[(21.6±4.1)min vs. (16.9±2.9)min, P<0.001] and higher failure rate of water injection test [16.7% (4/24) vs. 4.2% (1/24), P=0.045] than the non-leakage group. There was no significant difference in other indicators between the two groups. The results of multivariate logistic regression analysis showed that short MUL ( OR=0.544, 95% CI 0.335-0.884, P=0.014), narrow UWT ( OR=0.538, 95% CI 0.313-0.924, P=0.025) and long anastomotic time of urethrovesical neck ( OR=1.519, 95% CI 1.122-2.110, P=0.009) were independent risk factors for anastomotic urine leakage. ROC curve analysis showed that the AUC of MUL, UWT, and anastomotic time were 0.789 (95% CI 0.651-0.927), 0.715 (95% CI 0.562-0.868), and 0.842 (95% CI 0.731-0.953), respectively. Conclusions:Narrow and short membranous urethra and long anastomosis time in patients with laparoscopic radical prostatectomy may be independent risk factors for postoperative anastomotic leakage, which may predict the occurrence of anastomotic leakage.

ABSTRACT

Objective:To investigate the effectiveness of surgical treatment for patients with T 4 stage prostate cancer. Methods:The clinical data and prognosis of 18 patients with T 4 stage prostate cancer treated in Shanghai Tenth People's Hospital from July 2013 to December 2019 were retrospectively analyzed. The average age of these 18 patients was 68.3 (53-81)years. 10 patients were castration resistant prostate cancer (CRPC) and 8 patients were hormone-sensitive prostate cancer (HSPC). 10 CRPC patients were treated with surgical treatment due to bladder clot packing and/or lower urinary tract obstruction. 8 HSPC patients had severe hematuria, severe dysuria and local symptoms. The KPS scores of all patients were ≥80 points with an average score of 84 (80-90). The average QOL score of 18 patients was 28 (21-32). 2 cases in 18 patients underwent total pelvic resection for rectal invasion (one CRPC and one HSPC). 7 cases underwent radical cystoprostatectomy for ureteral invasion (5 cases of CRPC, 2 cases of HSPC), 9 cases underwent bladder preservation surgery for bladder neck invasion (4 cases of CRPC, 5 cases of HSPC), of which 4 cases of enlarged lymph node dissection were all HSPC patients. Results:All cases of T 4 stage prostate cancer patients operation were successfully completed, the average operation time was 256 (219-310)min and the median intraoperative blood loss was about 300 (250-350)ml. Four of them (3 cases of CRPC and 1 case of HSPC) received blood transfusion after operation. The average postoperative hospital stay was 21(11-37) days. All 18 cases were followed up and the median follow-up time was 23.8 months. There was no perioperative death, and no bladder-preserving patients had true urinary incontinence or bladder outlet stenosis.2 CRPC cases died 8 and 15 months after surgery respectively, 7 patients were PSA relapse treated with docetaxel or abiterone therapy, and 1 HSPC patient with rectal invasion was followed up for 58 months after total pelvic resection, the PSA level was still 0.003ng/ml, no distant metastasis was found. 8 cases of hormone-sensitive patients were treated with endocrine therapy, and PSA was less than 0.2 ng/ml. The average QOL of 18 patients 3 months after operation was 37 points (25-45), which was significantly higher than that before operation. The average maximum urine flow rate of patients with bladder preservation was 23(19-25)ml/s. Conclusions:For T 4 stage prostate cancer, surgical treatment is feasible and safe for doctors with extensive surgical experience. For CRPC patients, the surgery can significantly improve short-term symptoms and quality of life, and long-term benefits need to be further evaluated with a large sample. For HSPC patients, it can not only improve clinical symptoms and QOL of patients, but also provide long-term benefits.

ABSTRACT

Objective@#To analyze the clinical features of patients with chronic obstructive pulmonary disease(COPD) complicated with pulmonary thromboembolism(PTE).@*Methods@#The clinical data of 21 patients with COPD and PTE and 26 patients with acute exacerbation of COPD(AECOPD) from June 2015 to March 2018 in Taiyuan Central Hospital were retrospectively analyzed.The SSPS 22.0 statistical software was used to analyze the clinical data.General data, blood gas analysis results, lung function, hemoglobin, coagulation parameters, combined disease were analyzed.@*Results@#There were no statistically significant differences in age, gender and lung function grading between the COPD complicated with PTE group and AECOPD group (all P>0.05). The incidence rates of chest pain(8 cases, 38.1%) and syncope(2 cases, 10.5%) in the COPD complicated with PTE group were higher than those in the AECOPD group[chest pain(3 cases, 11.5%), syncope(1 case, 3.8%)](χ2=7.645, 9.413, all P<0.05). There was no statistically significant difference in carbon dioxide partial pressure(PaCO2)retention between the two groups(P>0.05). The blood oxygen partial pressure(PaO2) of the COPD complicated with PTE group was (62.86±15.10)mmHg, which was lower than that of the AECOPD group [(74.83±17.59)mmHg](t=4.642, P<0.05). The hemoglobin, activated partial thromboplastin time(APTT), fibrinogen(FIB), D-dimer levels in the COPD complicated with PTE group were (146.78±21.40)g/L, (35.62±5.93)s, (4.34±1.18)g/L, (5.02±3.63)mg/L, respectively, which were higher than those in the AECOPD group [(137.45±15.15)g/L, (29.38±3.16)s, (3.62±1.08)g/L, (0.92±0.42)mg/L] (t=4.375, 4.654, 3.869, 18.653, all P<0.05). There were no statistically significant differences in the proportion of comorbidities such as diabetes, hypertension, hyperlipidemia and lower extremity(all P>0.05).@*Conclusion@#COPD patients complicated with PTE have the following characteristics: elderly and male patients accounted for a high proportion, chest pain and syncope symptoms occurred in a high proportion, severe hypoxia, hemoglobin and D-dimer increased significantly.
