Male Wistar rats were classified into unoperated group （control group）, groups castrated at the age of 8weeks （group 8wPC） and groups castrated at the age of 4weeks （group 4wPC）. Each rat was used at the age of 20weeks. BBF was measured using fluorescent microspheres. Bladder cystometry was performed without anesthesia or restraint; the bladder was first irrigated with saline and then with 0.25% acetic acid （AA） solution. Maximum voiding pressure and voiding interval were measured. The bladder and lilac artery were histologically examined for differences in smooth muscle and quantity of collagen fiber to analyze the effect of castration on the smooth muscle content. No differences were noted in BBF following castration. The voiding intervals for all groups were shortened （P 〈 0.001） following AA irrigation. No significant difference was noted in the maximum voiding pressure. Histological changes were observed in bladder and lilac artery. Smooth muscle/collagen ratio at the bladder was lower in groups 8wPC and 4wPC compared to the control group （P 〈 0.01）, while that at the lilac artery was decreased in group 4wPC compared to the control group （P〈 0.001）. In conclusion, our findings indicate that castration does not alter BBF, but leads to histological changes in the bladder as well as its associated blood vessels.展开更多

Methods: 96 patients with extensive total hysterectomy received in our department from July 2019 to December 2020 were taken as observation objects and divided into two groups. The first group used routine nursing intervention and the second group used multidisciplinary cooperation intervention on the basis of the first group. The nursing effect and bladder dysfunction score of the two groups were compared, with 48 patients in each group. Results: (1) the infection rate of urinary system in the first group was significantly higher than that in the second group. The indwelling time of urinary catheter in the second group was longer than that in the second group. There was a difference between the two groups (P < 0.05). (2) The score of bladder dysfunction before and one month after operation in the first group was higher than that in the second group, with difference between the two groups (P < 0.05). Conclusion: multidisciplinary cooperative intervention is effective for patients with extensive total hysterectomy and is recommended.展开更多

Methods: 80 cases of prostate cancer patients received treatment in our hospital were selected as the object of the study, and then they were divided into equal groups, respectively as the control group and observation group. In the grouping study, patients in the control group were treated with open radical prostatectomy, while patients in the observation group were treated with laparoscopic radical prostatectomy. At the end of the study, the clinical indicators and improvement of bladder function of patients in the two groups were compared. Results: the clinical indicators and bladder function improvement data of the control group were compared for reference, and the observation group had significant advantages, P<0.05. Conclusion: in patients with prostate cancer treated by laparoscopic radical prostatectomy, clinical indicators and bladder function are improved, which has a positive impact on the improvement of prognosis and quality of life of patients.展开更多

Electrodes were implanted in S2 bilaterally and connected to the subcutaneous receivers for external activation. Microsurgical technique was employed to perform dorsal rhizotomy of S1-3 intradurally. The dogs were stimulated daily to observe micturition. Urodynamic testing and vesicography were performed. Results: All the dogs acquired micturition under the control of electric stimulation, with urine volume 80-140 ml per time. The mode of micturition was post-stimulus voiding. Vesicography revealed that the bladder was filled well and the bladder neck was open in the micturition course of electric stimulation. Residual urine volume was 15-20 ml. Urodynamic testing found that the bladder pressure and intraurethral pressure increased simultaneously, but when the intraurethral pressure was greater than the bladder pressure, no micturition occurred. The pressure decreased to baseline rapidly and the bladder pressure decreased slowly between two bursts. Micturition occurred when the bladder pressure was greater than the intraurethral pressure.Conclusions: The self-designed bladder controller together with a sacral deafferentation procedure can restore micturition function of paraplegic dogs.展开更多

Misdiagnosis of FPUB before operation can lead to serious intraoperative consequences. In this article, we reported our experience in preoperative diagnosis and surgical treatment of FPUB. Methods: Clinical data of nine patients with FPUB treated between June 1985 and January 2009 at Peking Union Medical College Hospital were analyzed. Results: All patients underwent urinary catecholamine (CA) detection, B-ultrasound, CT and/or MRI scan; 5 underwent nailfola microcirculation inspection; 4 underwent 131I-metaiodobenzyl guanidine (MIBG) detection; and 6 underwent 111In-DTPA-Octreotide (OCT) scintiscan. According to the UICC bladder tumor classification, 5 patients had T2, 3 had T3, and 1 had T4 disease. All patients underwent surgical treatment, and 1 received 131I-MIBG therapy. All patients had paroxysmal hypertension and palpitation and six had cold sweat, headache, and dizziness after emphatic urination. The definitive diagnosis was made by histopathologic examination of the removed tumors and was confirmed in 7 cases by the immunohistochemical staining of chromogranin A, Ki-67 and S100 protein. The tumor consisted of discrete aggregates of zellballen cells separated by a network of vascular channels. One patient had metastases in the pelvic lymph nodes, liver and colon. Follow-up ranged from 7 to 289 months (mean, 127.2 ± 34.2). Six of the nine cases reported here were found in the usual locations. One patient had multiple tumors. The catecholamine level was elevated under basal conditions in 8 patients and during endoscopic resection of the tumor in 1 patient; it returned to normal after surgery in 8 patients. Three patients had recurrence and 1 had metastasis following surgery. Conclusions: Early preoperative diagnosis of FPUB is difficult, but it should be suspected in patients with typical tetrad symptoms: headache and micturition syncope, sweating, palpitation and hematuria. In those patients with unresectable multiple tumors, medicine and 131I-MIBG therapy may be helpful for controlling hypertension and delaying disease progression. Advanced classification (≥T3), multifocal tumors and CgA expression are risk factors of recurrence and metastasis.展开更多

文摘We examined the effect of androgens on bladder blood flow （BBF）, bladder function and histological changes in castrated male rats. Male Wistar rats were classified into unoperated group （control group）, groups castrated at the age of 8weeks （group 8wPC） and groups castrated at the age of 4weeks （group 4wPC）. Each rat was used at the age of 20weeks. BBF was measured using fluorescent microspheres. Bladder cystometry was performed without anesthesia or restraint; the bladder was first irrigated with saline and then with 0.25% acetic acid （AA） solution. Maximum voiding pressure and voiding interval were measured. The bladder and lilac artery were histologically examined for differences in smooth muscle and quantity of collagen fiber to analyze the effect of castration on the smooth muscle content. No differences were noted in BBF following castration. The voiding intervals for all groups were shortened （P 〈 0.001） following AA irrigation. No significant difference was noted in the maximum voiding pressure. Histological changes were observed in bladder and lilac artery. Smooth muscle/collagen ratio at the bladder was lower in groups 8wPC and 4wPC compared to the control group （P 〈 0.01）, while that at the lilac artery was decreased in group 4wPC compared to the control group （P〈 0.001）. In conclusion, our findings indicate that castration does not alter BBF, but leads to histological changes in the bladder as well as its associated blood vessels.
