USE OF INTRAPERITONEAL PTFE DUAL-MESH IN A GIANT INCISIONAL HERNIA AFTER RENAL TRANSPLANTATION: A CASE REPORT

2008

Objectives: We evaluated the incidence of incisional hernia after kidney transplantation, predisposing factors and the results of surgical repair of a giant incisional hernia by intraperitoneal PTFE dual mesh. Patients and methods: We report our experience about an incisional hernia in a 55 years male after renal transplantation treated with an intraperitoneal dual mesh prosthesis. The cause of incisional hernia was probably due to an urinoma for a total necrosis of distal graft ureter that needed to reopen in 2sd day post transplant with primary fascial approximation. Thirty days after transplantation we discovered a large incisional hernia that rapidly became monstrous with migration of o…

Two Patients With History of STEC-HUS, Posttransplant Recurrence and Complement Gene Mutations

2013

Hemolytic uremic syndrome (HUS) is a disease of microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. About 90% of cases are secondary to infections by Escherichia coli strains producing Shiga-like toxins (STEC-HUS), while 10% are associated with mutations in genes encoding proteins of complement system (aHUS). We describe two patients with a clinical history of STEC-HUS, who developed end-stage renal disease (ESRD) soon after disease onset. They received a kidney transplant but lost the graft for HUS recurrence, a complication more commonly observed in aHUS. Before planning a second renal transplantation, the two patients underwent genetic screening for aHUS-associat…

Analysis of the renal transplant waiting list in the País Valencià (Spain).

2005

In this paper we analyse the renal transplant waiting list of the Pais Valencia in Spain, using Queueing theory. The customers of this queue are patients with end-stage renal failure waiting for a kidney transplant. We set up a simplified model to represent the flow of the customers through the system, and perform Bayesian inference to estimate parameters in the model. Finally, we consider several scenarios by tuning the estimations achieved and computationally simulate the behaviour of the queue under each one. The results indicate that the system could reach equilibrium at some point in the future and the model forecasts a slow decrease in the size of the waiting list in the short and mid…

The role of MR imaging in the assessment of renal allograft vasculature.

2018

Renal allograft dysfunction after transplantation is a relatively common occurrence with various potential etiologies. Vascular etiologies are of particular importance as early surgical or minimally invasive intervention can, in some cases, salvage the graft. Diagnosis of vascular pathology resulting in allograft dysfunction requires a thorough workup, of which imaging is a key component. Generally, ultrasound is the first-line imaging modality. More recently, MRI has been shown to be an effective and safe modality for diagnosis of vascular pathology after renal transplantation, particularly for diagnosis of transplant renal artery stenosis. This review will summarize imaging modalities tha…

Renal transplantation by automatic anastomotic device in a porcine model

2015

Automatic vascular staplers for vascular anastomoses in kidney transplantation may dramatically reduce the operative time and, in particular, warm ischemia time, thus increasing the outcome of transplantation. Ten pigs underwent kidney auto-transplantation by automatic anastomotic device. Kidneys were collected by laparotomy with selective ligations at the renal hilum and perfused with cold storage solution. To overcome the shortage in length of renal hilum, a tract of the internal jugular vein was harvested to increase the length of the vessels. The anastomoses were totally performed by the use of the anastomotic device. On 10 kidney transplants, nine were successful and no complications o…

Neural Networks Ensemble for Cyclosporine Concentration Monitoring

2001

This paper proposes the use of neural networks ensemble for predicting the cyclosporine A (CyA)concen tration in kidney transplant patients. In order to optimize clinical outcomes and to reduce the cost associated with patient care, accurate prediction of CyA concentrations is the main objective of therapeutic drug monitoring. Thirty-two renal allograft patients and different factors (age, weight, gender, creatinine and post-transplantation days, together with past dosages and concentrations)w ere studied to obtain the best models. Three kinds of networks (multilayer perceptron, FIR network, Elman recurrent network) and the formation of neural-network ensembles were used. The FIR network, y…

Advantage of eradication therapy for Helicobacter pylori before kidney transplantation in uremic patients.

2007

ABSTRACT From January 1999 to February 2007, 61 end-stage renal disease (ESRD) candidates for kidney transplantation underwent an esophagogastroduodenoscopy (EGDS) to detect Helicobacter pylori (HP). We correlated treatment for HP before transplantation and upper digestive tract hemorrhagic complications and possible recurrence of peptic disease posttransplantation. The 32 (52.4%) HP-Positive cases were divided into 2 groups: (1) 17 patients who underwent treatment for the eradication of the infection with 40 mg/d omeprazole for 4 weeks, 500 mg claritromycin twice daily for 7 days, and 2 g/d amoxicillin for 7 days; and (2) 15 untreated patients. No significant differences were found in the …
