Background and Objectives:
The aim of this retrospective study was to compare conventional laparoscopic living-donor nephrectomy with transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy in terms of feasibility and reproducibility.Methods:
A total of 115 consecutive female patients who underwent laparoscopic living-donor nephrectomy (n = 70) or transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy (n = 45) were included and compared in terms of operative characteristics, as well as donor and recipient outcomes.Results:
No significant difference was observed between the laparoscopic living-donor nephrectomy and transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy groups in terms of mean duration of warm and cold ischemia, operation time, length of hospital stay, arterial anastomoses, visual analog scale pain scores, serum creatinine levels, and receiver outcomes, whereas a significantly higher number of venous anastomoses was noted in the laparoscopic living-donor nephrectomy group than in the transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy group (P = .029).Conclusions:
Transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy seems to be a feasible and reproducible alternative to conventional laparoscopic living-donor nephrectomy in female donors provided the viability of the vagina as an organ retrieval route. 相似文献3.

The myocardial performance index (MPI) reflects global ventricular function. Chronic hypervolemia and uremia may negatively
affect the myocardium of both ventricles. The aims of this study were to investigate how chronic renal failure (CRF) affects
biventricular MPI and to determine whether preload reduction by hemodialysis (HD) affects left ventricular MPI (LVMPI) and
right ventricular MPI (RVMPI) in CRF. Twenty-one patients with CRF (group 1) were examined 1 hour before and 1 hour after
an HD session and 1 7 healthy control patients (group 2) were examined once by echocardiography. The MPI for each ventricle
was calculated as the sum of isovolumic time intervals divided by the ejection time. Before HD, the LVMPI of group 1 was similar
to that in group 2 (P≫.05), but the RVMPI of group 1 was significantly higher (P=.007). After the HD session, LVMPI and RVMPI remained unchanged (P>.05 for both). The LVMPI and RVMPI were not correlated either before or after HD in group 1 (P>.05 for both), whereas they were correlated in group 2 (r= 0.671, P=.003). Chronic renal failure causes isolated RV dysfunction, as reflected by increased RVMPI values. Preload reduction
by HD does not affect LVMPI or RVMPI. Patients with CRF also do not exhibit the correlation of LVMPI and RVMPI that is observed
in healthy individuals. 相似文献

Ten fresh mandibles from adult sheep were stripped of all soft tissues and sectioned in the midline. We did sagittal split osteotomies and 5 mm advancement on all the 20 hemimandibles. Ten hemimandibles were fixed with three 2.0 mm x 13 mm titanium bicortical screws, and the other 10 were fixed with three 2.0 mm x 13 mm poly-l-lactic acid/polyglycolic acid (PLLA/PGA) bicortical screws in an inverted L pattern. All the hemimandibles were then mounted in a servohydraulic testing unit and tested to permanent deformation. Maximum forces that the mandibles resisted before breaking, maximum displacements, and the displacement values under 20, 60, 120, and 150 N were compared using the Mann-Whitney U-test. There were no significant differences in stability between the bones fixed with titanium and those fixed with resorbable screws. 相似文献

Many aspects of calcium oxalate (CaOx) deposition in renal transplant biopsies are not known. Review of all renal transplant biopsies performed in a 7-year period showed that CaOx deposition could be classified into three groups. Group I: Seven biopsies within a month post-transplant displayed rare CaOx foci against a background of acute tubular necrosis or acute cell-mediated rejection. At follow-up, five grafts functioned well and two failed due to chronic allograft nephropathy. CaOx in this context was an incidental finding secondary to a sudden excretion of an end-stage renal disease-induced increased body burden of CaOx. Group II: Two biopsies performed 2 and 10 months post-transplant showed rare CaOx foci against a background of chronic allograft nephropathy, leading to graft loss. CaOx in this context reflected nonspecific parenchymal deposition due to chronic renal failure regardless of causes. Group III: One biopsy with recurrent PH1 characterized by marked CaOx deposition associated with severe tubulointerstitial injury and graft loss 6 months post-transplant. There were two previously reported cases in which CaOx deposition in the renal allografts was due the antihypertensive drug naftidrofuryl oxalate or increased intestinal absorption of CaOx. CaOx deposition in renal allografts can be classified in different categories with distinctive morphologic features and clinical implications. 相似文献

IntroductionThe possible effects of radiocolloid preference on sentinel lymph node biopsy (SLNB) were investigated.MethodsA total of 200 patients with T1-2N0M0 breast cancer were evaluated. The first 100 patients underwent SLNB using 99mTc tin colloid (TC) and the next 100 using 99mTc nanocolloid (NC). Radiocolloid was injected intradermally at four quadrants of the periareolar region the day before surgery. All patients underwent lymphoscintigraphy 1 h after injection. All nodes having fourfold activity of the background were harvested using gamma probe.ResultsSentinel lymph node (SLN) identification rate by gamma probe was 98% in each group. The number of SLNs identified by lymphoscintigraphy, gamma probe and pathological evaluation was 1.39±0.7, 1.70±1.0 and 2.23±1.70 in the TC and 2.03±0.94, 2.60±1.36 and 3.05±1.90 in the NC group, respectively (P<.05). Metastatic SLN was found in 24 (24.4%) of 98 patients in the TC group and 41 (41.8%) of 98 patients in the NC group (P=.04). None of the patients showed dispersion to internal mammarian lymph nodes. Lymphatic vessel visualization was observed in eight (8.1%) of 98 TC patients and in 47 (47.9%) of 98 NC patients (P=.000). SLNs were the only metastatic node(s) in 54.1% of TC and 73.1% of NC patients.ConclusionThe periareolar intradermal injection technique gives a high detection rate in the localization of SLNs independently from the choice of the tracer. Mean SLN numbers and lymphatic vessel visualization frequency were significantly higher using a smaller albumin Tc-99m nanocolloid as compared to a stannous fluoride Tc-99m tin colloid. The results of our study support the idea that the influence of increased number of SLNs on positive SLN frequency is critical. 相似文献

Subcutaneous emphysema is the condition in which air or other gases penetrate the skin and submucosa causing soft-tissue distention. This type of emphysema may be traumatic, iatrogenic or may occur spontaneously. This report describes the youngest case of subcutaneous emphysema related to dental treatment that has been documented to date. In addition to the patient's age, the case is of interest because subcutaneous emphysema is a rare complication of dental therapy. 相似文献

OBJECTIVE: The objective of this study was to investigate the cystic changes in radiographically normal follicles associated with impacted lower third molars (ILTM). The relation between the cystic changes and both the angular position and the contact of ILTM with the adjacent tooth was also evaluated. STUDY DESIGN: Follicular spaces of patients who were referred to our clinic for removal of ILTM for a variety of reasons were measured from panoramic radiographs by each author independently. Pericoronal tissues of radiographically normal impacted third molars were examined histopathologically. Then the data were analyzed for associations with age, sex, angular position, and contact of the ILTM with the second molar. RESULTS: There were 30 male and 64 female patients, ages ranging from 14 to 45 years (mean = 21.11). Forty-seven (50%) of the 94 specimens showed cystic changes as the only pathological condition other than inflammation. Most of the cystic changes occurred in the 20-25 year age range. The relation between cystic changes and angular position was statistically significant (chi 2 = 7.46, P < .05). The higher probability of cystic changes was found in the vertically positioned ILTM. The relation between the cystic changes and communication of ILTM with the second molar was not statistically significant (chi 2 = 2.068, P > .05). CONCLUSIONS: Cystic changes may be encountered in the histopathologic examination of asymptomatic third molars, especially in patients older than 20 years. Vertically positioned ILTM especially may be suspected for the higher possibility of cystic changes. 相似文献

The role of K(ATP) channels in the antiarrhythmic effect of Escherichia coli endotoxin-induced nitric oxide synthase (iNOS) was examined in an anesthetised rat model of myocardial ischemia and reperfusion arrhythmia by using glibenclamide (1 mg kg(-1)), nateglinide (10 mg kg(-1)) and repaglinide (0.5 mg kg(-1)). Endotoxin (1 mg kg(-1)) was administered intraperitoneally 4 h before the occlusion of the left coronary artery and glibenclamide, nateglinide or repaglinide was administered 30 min before coronary artery occlusion. We also evaluated the effects of K(ATP) channel blockers and nonselective K(+) channel blocker tetraethylammonium (TEA) on cardiac action potential configuration in the atria obtained from endotoxemic rats. The mean arterial blood pressure of rats receiving endotoxin was lower during both the occlusion and reperfusion periods. Endotoxin significantly reduced the total number of ectopic beats and the duration of ventricular tachycardia. Glibenclamide, but not nateglinide and repaglinide, prevented the hypotension and antiarrhythmic effects of endotoxin. Atria obtained from endotoxin-treated rats had prolonged action potential duration. This effect was abolished with pretreatment of iNOS inhibitors, l-canavanine and dexamethasone and perfusion of glibenclamide, but not with TEA and non-sulfonylurea drug, nateglinide. We demonstrated that glibenclamide inhibits the antiarrhythmic effect of endotoxin and this effect does not appear to involve K(ATP) channels. 相似文献
