The postoperative management of the highly sensitized renal transplant recipient with delayed graft function on cyclosporine is complicated. Allografts with delayed graft function are reported to have a 20 to 30% poorer 1-year survival than allografts without delayed graft function. Several factors may be implicated in this poorer 1-year survival. A decrease in or cessation of cyclosporine dosage frequently is used in an attempt to minimize nephrotoxicity. Such under-immunosuppression can result in irreversible rejection. Occasionally, a pessimistic view of the prognosis for the transplant may result in early abandonment of the allograft with discontinuation of immunosuppression and allograft nephrectomy. We report on 3 highly sensitized patients whose kidneys had delayed graft function and were deliberately maintained on high doses of cyclosporine throughout the period of delayed graft function. Each graft achieved function (2, 4 and 5 months) after transplantation. The serum creatinine levels 20, 28 and 38 months after transplantation were 2.7, 2.0 and 1.0 mg./dl., respectively. We suggest that the maintenance of high cyclosporine levels throughout the delayed graft function period is useful in highly sensitized recipients and was an important factor in their successful outcome. A management protocol for such patients is proposed.

Wound healing is a complex and dynamic biological process that requires meticulous management to ensure optimal outcomes. Traditional wound dressings, such as gauze and bandages, although commonly used, often fall short in their frequent need for replacement, lack of real-time monitoring and absence of anti-inflammatory and antibacterial properties, which can lead to increased risk of infection and delayed healing. Here, we address these limitations by introducing an innovative hydrogel dressing, named PHDNN6, to combine wireless Bluetooth temperature monitoring and light-triggered nitric oxide (NO) release to enhance wound healing and management.

Background: Autosomal Dominant Polycystic Kidney Disease (ADPKD) represents the most common monogenic cause of kidney failure. While identifying genetic variants predicts disease progression, characterization of recently described ADPKD-like variants is limited. We explored disease progression and genetic spectrum of genetically-confirmed ADPKD families with PKD1 and non-PKD1 variants.

Introduction: A significant portion of posterior urethral valve patients continue to progress to end stage renal disease despite improvements in medical care. Socioeconomic status has been connected to various healthcare outcomes but has not been evaluated in relation to longitudinal outcomes of posterior urethral valves.
Objective: To evaluate the effect of socioeconomic status on the progression to renal failure among patients with posterior urethral valves.

This study aimed to assess the feasibility and retention rates of pedicled thymic flaps to enhance understanding of bronchial stump coverage. A retrospective analysis of 22 consecutive patients who underwent anatomical lung resection followed by bronchial stump coverage with pedicled thymic flaps between January 2017 and December 2022 was conducted. The procedure was performed using a minimally invasive 3-port video-assisted thoracoscopic surgery technique for all patients with no complications related to graft harvest or fixation.

Background: KEPs (kidney exchange programs) facilitate living donor kidney transplantations (LDKT) for patients with incompatible donors, who are typically higher risk than non-KEP patients because of higher sensitization and longer dialysis vintage. We conducted a comparative analysis of graft outcomes and risk factors for both KEP and non-KEP living donor kidney transplants.
Methods: All LDKTs performed in the Netherlands between 2004-2021 were included.
