Article Abstract

Introduction: Management strategies for Nutcracker syndrome (NCS) differ across vascular and transplant surgery, with options such as left renal vein stenting and renal autotransplantation offering potential long-term pain relief.

Methods: A decision-analytic Markov state transition model was generated to simulate NCS management strategies over a two-year time horizon: Stent First, Autotransplantation, Stent Only, and No Intervention.

Results: Autotransplantation achieved the highest rate of pain resolution at 77.0 ​% followed by Stent First at 64.9 ​% after two years. Stent Only and No Intervention demonstrated the lowest rates of pain resolution at 51.8 ​% and 0 ​%, respectively. The estimated cumulative morphine milligram equivalents (MMEs) over the simulated two-year period were approximately 5037 MMEs for Autotransplantation, 7684 MMEs for Stent First, 10,556 MMEs for Stent Only, and 21,900 MMEs for No Intervention.

Conclusion: Renal autotransplantation was associated with higher rates of pain resolution and lower opioid usage over a simulated two-year period.

Rationale: Ureteral stricture is a complex urological condition often requiring surgical intervention. Autologous tissue grafts, such as lingual mucosa, have emerged as a promising option for reconstruction due to their favorable biocompatibility and vascularity. However, reports on complications associated with these techniques remain limited.

Background: The management of long proximal ureteral strictures poses a significant challenge, with traditional options such as renal autotransplantation or bowel interposition associated with substantial morbidity. This study explores the use of robotic ureteroplasty with lingual mucosal graft (RU-LMG) as a minimally invasive approach for treating complex ureteral strictures. We present a multi-institutional cohort to evaluate its effectiveness in managing proximal and mid-ureteral strictures.

Mucositis involving the gastrointestinal, vaginal, and nasal mucosa is one of the primary dose-limiting toxicities of hematopoietic stem cell transplantation (HSCT) and its conditioning regimen. The oropharyngeal mucosa is commonly affected, which can be detrimental to patient health and quality of life. Despite its significant prevalence and deleterious effects, we have an inadequate understanding of the risk factors and outcomes associated with oral mucositis (OM).

Teclistamab, a B-cell maturation antigen-targeting bispecific antibody, offers a promising treatment option for relapsed/refractory multiple myeloma (RRMM), even in patients with severe renal impairment. The present study describes the case of a 47-year-old woman with RRMM who achieved minimal residual disease negativity and dialysis independence following teclistamab treatment. Despite prior resistance to multiple therapies, including an anti-CD38 monoclonal antibody (daratumumab), two proteasome inhibitors (bortezomib and carfilzomib), an immunomodulatory drug (lenalidomide), an exportin 1 inhibitor (selinexor), a BCL-2 inhibitor (venetoclax) and dexamethasone, and post-autologous stem cell transplantation relapse, teclistamab induced a deep hematological response.

Objective: Secondary and tertiary hyperparathyroidism in children with chronic kidney disease (CKD) require complex management. Surgical intervention aims to reduce parathyroid hormone (PTH) levels in CKD patients, thereby preventing complications associated with hyperparathyroidism (HPT). We describe our 13-year experience in the surgical management of secondary and tertiary hyperparathyroidism in pediatric patients, including total or subtotal parathyroidectomy, autoimplantation, cryopreservation, and deferred autoimplantation.
