PURPOSE: Renal allograft compartment syndrome (RACS) is early graft dysfunction secondary to retroperitoneal hypertension and resultant ischemia. Our purpose was to identify the incidence, therapies and outcomes of patients with RACS. METHODS: All patients who underwent a renal transplant between 2000 and 2005 were reviewed. Patients with signs of acute allograft dysfunction were identified. RACS was diagnosed via visual allograft hypoperfusion and/or with preoperative Doppler ultrasound. RESULTS: Among 458 patients, 11 (2%) were diagnosed with RACS. Characteristics between patient groups were similar. Five (45%) patients displayed adequate initial allograft function after transplantation. Doppler ultrasound was diagnostic. Six (55%) patients displayed poor initial allograft function and were classified as early presenters of RACS. Allograft function improved dramatically upon decompression. CONCLUSIONS: Clinicians must remain aware of RACS as a potential diagnosis when patients display rapid deterioration in kidney performance after good initial allograft function. Doppler ultrasound is useful in diagnosing late presenters. 相似文献

Renal cell carcinoma arising from epithelial cells of the renal tubule is a highly aggressive and malignant tumor in all ages. Less than 2% of cases occur in childhood, relatively in older age group. Only a few pediatric series have been presented in the English literature. Tumor is presented with characteristic findings of flank pain, gross hematuria, and palpable mass. Although one half of the patients have metastasis at the time of diagnosis, most cases are currently being incidentally detected using improved imaging techniques. The overall prognosis in children appears to be similar to that in adults. Tumor stage and complete surgical resection have been reported as the most meaningful prognostic factors for the outcome. The incidence of metastatic disease is same as in adults. The effect of chemotherapy and immunotherapy, either preoperatively or postoperatively, is unclear. Cure is the most likely consequence in localized and completely resected tumors. Here, we present an 8-year-old boy with renal cell carcinoma demonstrating only hematuria without any pathological physical examination findings. The mass was described by abdominal ultrasonography and computed tomography in the left kidney. After the left nephroureterectomy, the patient was given no therapy. 相似文献

We report three cases of renal abscess in otherwise healthy boys. One had a history of blunt trauma and two of antecedent skin infection. All presented with flank pain and fever. Urine and blood cultures were sterile. The diagnosis was made using ultrasound and computerized axial tomography. The first patient had recurrent renal abscess, following surgery and a short course of antibiotics. Eventually all responded well to long-term antibiotics only. 相似文献

Tuberculosis or TB (tubercle bacillus) remains a major public health problem in developing countries. Over the last decades extra-pulmonary locations of the disease have become more frequent due to the increased prevalence of acquired immune deficiency syndrome and the increase number of organ transplants. The urogenital localization represents about 27% of all extra-pulmonary localizations of TB and may be due either to a disseminated infection or to a primitive genitourinary localization. The majority of patients, has pyuria, sometimes with hematuria. The diagnosis of urinary tuberculosis is based on the finding of pyuria in the absence of infection by common bacteria. The initial medical treatment includes isoniazide, rifampicin, pyrazinami-de, ethambutol and streptomycin. This disease should be suspected in patients with unexplained urinary tract infections, especially if immunocompromised and/or coming from endemic areas. 相似文献

膝关节镜下同种异体半月板移植术(附2例初步报告) 总被引:3,自引:1,他引:3
[目的]通过对2例临床同种异体半月板移植中移植物取材、储存,手术操作技术、术后康复计划和不良反应等方面初步结果的总结,结合相关文献,讨论目前临床异体半月板移植的有关问题,为进一步开展此项临床技术提供参考。[方法]对2例外伤导致严重陈旧性半月板损伤、大部缺失的患者,在关节镜下实施同种异体半月板移植术,拟定术后康复计划,对其症状缓解、关节活动度恢复等近期随访结果作初步报告。[结果]患者无手术副损伤,术后伤口愈合良好,无明显伤口渗液,早期关节肿胀,6周左右肿胀消失。实验室检查未发现免疫排斥反应等征象。疼痛评分术前8分、6分,术后3分、2分。患者膝关节活动度恢复过程顺利。[结论]基于目前对半月板严重损伤者保留和修复半月板治疗中存在的困难,以及半月板属于免疫屏蔽器官的特点,异体半月板移植技术有可能成为治疗半月板严重损伤、缺失的一项重要技术。迄今已有的研究为其提供了充分的理论依据。但目前对其远期效果尚待进一步观察,关于移植物的消毒储存、手术操作技术、功能康复训练等临床问题也有待于进一步研究。 相似文献

Malakoplakia is an inflammatory condition associated with persisting bacterial antigen in macrophages and characterised histologically by the Michaelis-Gutmann body, containing bacterial fragments. We review the pathogenesis of malakoplakia and report a novel form of treatment successfully used in an 8-week-old infant with bilateral renal malakoplakia. The patient presented with an acuteEscherichia coli urinary tract infection and enlarged kidneys. Antibiotic regimes were ineffective, but once the diagnosis was made treatment was changed to an immunosuppressive regime of prednisolone and azathioprine, to which she responded promptly. Renal malakoplakia should be considered in any patient with a urinary tract infection unresponsive to antibiotics and enlarged kidneys. Although a large proportion of patients with malakoplakia have an underlying systemic disorder, which may account for their abnormal macrophage function, the rest demonstrate either an isolated macrophage defect or no detectable anomaly at all. It is in this latter group we suggest that an immunomodulating regime can be curative. 相似文献

Three cases of plunging ranula are described and the literature is reviewed. In many cases, a plunging ranula is iatrogenic and follows surgery to an oral ranula. In the cases presented, the cervical swelling was associated with prolongations of sublingual gland into or through the mylohyoid muscle. All patients were cured by partial or total excision of the sublingual gland. 相似文献

Renal oncocytoma: review of literature and report of six cases 总被引:1,自引:0,他引:1
6 cases of renal oncocytomas are described. Preoperative diagnosis is difficult in spite of new clinical diagnostic methods. In our series oncocytoma was diagnosed angiographically in 1 case and in 3 cases carcinoma was suspected. 5 of 6 cases, reevaluated postoperatively, fulfilled three of the four criteria of Ambos et al. for oncocytoma. Ultrasonography is a good exclusion diagnostic method for renal neoplasms. Oncocytoma may be suspected if the tumor projects nearly totally outside the renal contour as we found in 3 of our 6 cases. Aspiration biopsy smears have a diagnostic value in the evaluation of renal neoplasms. Cytologically we preoperatively diagnosed oncocytoma in 1 of 3 cases in which biopsy was performed. We warn, however, about the mosaic pattern of renal neoplasms. Renal cell carcinomas may have large areas composed of oncocytes. Frozen section analysis is a potentially hazardous peroperative diagnostic method in large tumors if oncocytoma is suspected. 相似文献

Open in a separate window OBJECTIVESRenal transplantation is an effective treatment for end-stage renal failure. The aim of this study was to evaluate outcomes for these patients undergoing cardiac surgery.METHODSA retrospective analysis identified patients with a functioning renal allograft at the time of surgery. A 2:1 propensity matching was performed. Patients were matched on: age, sex, left ventricle function, body mass index, preoperative creatinine, operation priority, operation category and logistic EuroSCORE.RESULTSThirty-eight patients undergoing surgery with a functioning renal allograft were identified. The mean age was 62.4 years and 66% were male. A total of 44.7% underwent coronary artery bypass grafting and 26.3% underwent a single valve procedure. The mean logistic EuroSCORE was 10.65. The control population of 76 patients was well matched. Patients undergoing surgery following renal transplantation had a prolonged length of intensive care unit (3.19 vs 1.02 days, P < 0.001) and hospital stay (10.3 vs 7.17 days, P = 0.05). There was a higher in-hospital mortality (15.8% vs 1.3%, P = 0.0027). Longer-term survival on Kaplan–Meier analysis was also inferior (P < 0.001). One-year survival was 78.9% vs 96.1% and 5-year survival was 63.2% vs 90.8%. A further subpopulation of 11 patients with a failed renal allograft was identified and excluded from the main analysis; we report demographic and outcome data for them.CONCLUSIONSPatients with a functioning renal allograft are at higher risk of perioperative mortality and inferior long-term survival following cardiac surgery. Patients in this population should be appropriately informed at the time of consent and should be managed cautiously in the perioperative period with the aim of reducing morbidity and mortality. 相似文献

Lipomeningioma is a benign tumor of the meninges that contains mature adipose tissue. It demonstrates fat density on computed tomographic scan and mixed signal intensities on magnetic resonance imaging scan. Although the pluripotential nature of the mesenchymal cell has long been recognized, only a single case with this diagnosis has been documented in the literature to date. Three patients with this diagnosis seen at the Johns Hopkins Hospital during the last two years are presented, and the literature is reviewed. 相似文献
