OBJECTIVE: To determine whether there is a significance of the choice of prone versus supine position in the treatment of proximal ureter stones with extracorporeal shock wave lithothripsy (ESWL). METHODS: Ninety-six patients with proximal ureter stones underwent ESWL. The procedure was performed in the supine position in 48 of them (group 1) and in the prone position in the other 48 patients (group 2). Stone-free rates, repeat ESWL rates, shocks per patient and shocks per session were compared in both groups. RESULTS: The mean session number per patients was 1.64+/-0.75 in group 1 and 1. 33+/-0.59 in group 2 (p = 0.224). The stone-free rates 3 months after ESWL were 88.3% in group 1 and 90.6% in group 2. The difference between the results was statistically insignificant (p<0.05). Therefore, these two parameters were similar in both groups. On the other hand, the number of shocks per session was 4,863.54+/-2, 114.85 in group 1 and 3,704.16+/-1,726.75 in group 2. This difference was statistically significant (p = 0.011). The patients tolerated the supine position better in general. Patients in the prone position experienced discomfort on inspiration and expiration and pain localized to the lumbar vertebrae. CONCLUSION: These results suggest that the supine position decreases the number of shocks per session in the treatment of proximal ureter stones with ESWL and this will be cost-effective. 相似文献

Perioperative spasm of internal mammary artery is a common experience in coronary artery bypass grafting. Many techniques were described of harvesting the internal mammary artery to prevent vasospasm. We investigated the comparison of the contracting and relaxing responses of human internal mammary artery grafts harvested by two different methods. Patients were divided into two groups depending on the harvesting technique. In the first and second groups arteries were harvested by classical and carbon dioxide insufflation techniques, respectively. In both groups, endothelial function of arteries was assessed by precontracting the rings with phenylephrine (10(-5)M) and dilatating them by cumulative acetylcholine (10(-8) to 10(-5)M) concentrations. Cumulative concentration-response curves for phenylephrine (10(-8) to 10(-4)M), noradrenaline (10(-9) to 10(-4)M), and 5-hydroxytryptamine (10(-9) to 10(-4)M) were obtained in all groups. Endothelial integrity of arteries were histopathologically evaluated. In both groups, acetylcholine caused concentration-dependent relaxations in rings precontracted with phenylephrine (10(-5)M). In arteries harvested by carbon dioxide insufflation technique, acetylcholine caused significantly higher relaxations compared to the rings obtained by classical technique (p<0.05). In all rings of study groups, phenylephrine, noradrenaline and 5-hydroxytryptamine caused concentration-dependent contractions. There was not any significant difference in concentration-dependent responses of these contracting pharmacological agents between the groups. Histopathological evaluation revealed no major arterial damage in both groups. Carbon dioxide insufflation technique does seem not only to protect the integrity of the endothelium and the whole vessel, but also prevent the possible vasospasm of the internal mammary artery segments. 相似文献

GOALS To investigate the relationships between gastric emptying and autonomic dysfunction in hepatic cirrhosis and to assess the effects of cisapride on gastric emptying in cirrhotic patients.STUDY Twenty-four cirrhotic patients (8 patients in each Child-Pugh classification) and 25 healthy controls were enrolled. All the patients had viral (B or C) hepatitis. Patients with DM, alcoholic cirrhosis, active peptic ulcer, gastric malignancy and pyloric obstruction were excluded by esophagogastroduodenoscopy. Parasympathetic and sympathetic functions were assessed by the criteria set forth by Ewing and Clark. Drugs affecting GI motility and smoking were discontinued 48 hours and 12 hours prior to the study respectively. A solid-phase of gastric emptying study was conducted by scintigraphic method for the calculation of gastric half-emptying time (GET1/2). RESULTS The study revealed that 9 patients with Child-Pugh B and C cirrhosis had autonomic neuropathy and none of Child-Pugh A cirrhosis had autonomic neuropathy. Prolonged GET1/2 was noted in cirrhotics compared with the control group (p < 0.05). However, there was significant difference between 9 patients (Child B-C) with autonomic neuropathy compared with patients 15 patients without autonomic neuropathy. Again there was a significant difference in GET1/2 between Child A cirrhotic and Child B-C cirrhotic whether they had autonomic neuropathy or not. Cisapride decreased GET1/2 significantly in cirrhotic patients (Child B-C cirrhotic). Clearly, patients with autonomic neuropathy in Child B-C cirrhosis had significantly reduced GET1/2 after cisapride administration. Even though cisapride decreased GET1/2 in patients with Child B-C cirrhosis without autonomic neuropathy, this was not significant. CONCLUSION Autonomic neuropathy in advanced cirrhosis from viral hepatitis may cause prolonged gastric emptying. Cisapride can shorten gastric emptying time in such patients. 相似文献

Endometrial stromal sarcoma (ESS) is a rare mesenchymal tumor with characteristic histological appearances, consisting of diffuse infiltrate of small uniform endometrial stromal cells with a multinodular arrangement and distinct vascular pattern. Less common variants of ESS include "mixed endometrial stromal and smooth muscle tumors", "endometrial stromal tumors resembling ovarian sex cord tumors" and "endometrial stromal neoplasms with endometrial glands", and "aggressive endometriosis". Rarely do endometrial stromal tumors have a prominent fibrous or myxoid appearance which causes confusion and possible misdiagnosis as myxoid leiomyosarcoma. In this report we present a very unusual subtype of ESS in a 32-year-old woman. The tumor revealed atypical pleomorphic bizarre cells which were stained positive only with vimentin and CD10 in an abundant myxoid matrix. A low-proliferative rate was established with MIB-1 staining. To our knowledge such appearance has not been previously reported. 相似文献
