Study on the recovery of bladder function in patients with cervical cancer after operation by portable ultrasound combined.

BACKGROUND: Postoperative urination dysfunction is a common complication after surgery in patients with cervical cancer. Portable bladder ultrasound are commonly utilized in clinical practice for measuring residual urine volume. This study aimed to the effect of bladder function training combined with portable ultrasound monitoring on bladder function recovery in patients with cervical cancer after training. METHODS: A total of 40 postoperative patients with cervical cancer were randomly divided into a control group (A) and an experimental group (B) of 20 cases each. Group A was given routine postoperative care, while group B was given bladder function training. Urgent urine bladder volume were taken twice daily after removal of the urinary catheter and monitored for five consecutive days. The difference of urgent urine bladder volume and bladder filling rate were compared by t-test and chi-square test respectively. The 36-item Short Form Health Survey (SF-36) was used to evaluate the quality of life of patients before and after intervention, and compared by Mann-Whitney U test. RESULTS: There was no significant difference in preoperative urgent urine volume between the two groups. After catheter removal, the bladder volume of patients in the B increased, while the bladder volume of patients in the A increased less and fluctuated greatly. The bladder filling rate in the A was significantly lower than that in the B (5/15 vs 17/18, p < 0.05). After intervention, the quality of life of the experimental group was better than that of the control group, including scores of general health, mental health, vitality, and physical role (p < 0.05). CONCLUSION: Postoperative cervical cancer patients trained to hold urine by portable ultrasound monitoring are able to recover bladder function.

Effect of bladder filling status on positioning errors in post-hysterectomy cervical cancer radiotherapy.

Objective: To investigate the effect of different bladder filling states on positioning errors in radiotherapy for cervical cancer and obtain the reference range of bladder filling consistency during radiotherapy.Methods: Patients who underwent postoperative radiotherapy for cervical cancer in Nantong Tumor Hospital from October 2018 to December 2019 were selected. According to the bladder filling deviation, they were divided into group A1 (deviation < 20%) and group B1 (deviation ≥ 20%). The bladder filling variations of the two groups were compared with different positioning errors. Group A2 has a positioning error of <0.4 cm, and group B2 has a positioning error of ≥0.4 cm. The reference range of bladder filling consistency during radiotherapy is obtained by analyzing the composition ratio of different positioning errors of bladder filling deviation.Results: This study included 195 patients with cervical cancer. The error of longitudinal and vertical position in group B1 was significantly higher than that in group A1 (0.50 ± 0.34 vs. 0.26 ± 0.22 cm, p < 0.001, and 0.22 ± 0.17 vs. 0.16 ± 0.12 cm, p < 0.001). Compared with group B2, the absolute deviation of bladder filling in group A2 (54.1% ± 54.4% vs. 25.6% ± 22.7%, p < 0.001) was slight. The chi-square test showed significant differences in the proportion of the positioning state of different bladder filling forms (χ2 = 31.006, p < 0.001). In addition, there was a significant difference in the proportion of stability errors in patients with poor stability in different directions (χ2 = 118.551, p < 0.001).Conclusion: In patients with cervical cancer fixed in the supine position, a bladder capacity deviation <20% is easier to achieve excellent positioning with, and it can better control the positioning error of radiotherapy and ensure the positioning accuracy of dose distribution to the target area. It can also achieve good tumor treatment effects. This range can be used as a reference for bladder filling consistency in patients with cervical cancer undergoing radiotherapy.

[Combined three-dimensional conformal radiotherapy plus transcatheter arterial chemoembolization and surgical intervention for portal vein tumor thrombus in patients with hepatocellular carcinoma].

OBJECTIVE: To explore the clinical therapeutic efficacies of combined three-dimensional conformal radiotherapy (3DCRT) plus transcatheter arterial chemoembolization (TACE) for portal vein tumor thrombus (PVTT) in hepatocellular carcinoma (HCC). METHODS: A total of 145 HCC patients with tumor thrombus in portal vein were divided randomly into 2 groups. Group A (n = 64) was treated with surgical intervention alone while group B (n = 81) underwent 3DCRT plus TACE. The gross tumor volume (GTV) was defined as PVTT only. RESULTS: Survival rates of group A at year 1 and 2 were 40.3% and 21.9% with a mean survival time (MST) of 15.2 months while that of group B were 41.2% and 22.5% with a MST of 15.8 months. The total effective rates of groups A and B was 40.6% (28/64) and 44.4% (36/81) respectively. CONCLUSION: The therapeutic efficacy of 3DCRT plus TACE is similar to that of surgical intervention.
