Purpose: To report our preliminary techniques and experience with transumbilical laparoendoscopic single-site renal pedicle lymphatic disconnection (LESS-RPLD) in seven patients with refractory chyluria.
Patients And Methods: Between June 2009 and September 2010, seven patients with refractory chyluria underwent LESS-RPLD. In the patients, a 2- to 3-cm single inverted U-shaped supraumbilical incision was made, and a homemade single multichannel port using a surgical glove and three conventional trocars was placed into the abdominal cavity. Flexible electric coagulation hook and pliers were used for renal pedicle dissection. A straight ultrasound knife was used for lymphatic disconnection.
Results: All the operations were successfully completed without conversion to open surgery, although an additional 3-mm trocar was used to push the liver in one patient. The mean operative time was 125 (96-165) minutes. The mean blood loss was estimated to be 112 (50-250) mL. Chyluria disappeared in all patients after surgery and did not recur during the follow-up period (3-15, mean 8.3 mos).
Conclusion: LESS-RPLD is safe and feasible, with favorable short-term outcomes and aesthetic effect.

Concurrent Renorrhaphy During Renal Mass Excision in Laparoscopic Nephron-Sparing Surgery: A Novel Surgical Technique.

Objective: Laparoscopic nephron sparing surgery (NSS) can be performed by mainly 2 methods, offclamp or on-clamp. Continuous bleeding during the off-clamp method may impair the clear visualization of the border between the tumor and parenchyma, even though it is done safely in experienced hands. Therefore, some surgical modifications may be needed during mass excision and renorraphy.

Kidney allograft torsion (KAT) is a rare but critical complication of kidney transplantation that can lead to graft loss due to acute ischemia. This report presents a case of KAT resulting in graft loss 9 months following intraperitoneal simultaneous pancreas and kidney (SPK) transplant and reviews previous reports to identify potential high-risk features. A 38-year-old female with end-stage renal disease secondary to Type 1 diabetes mellitus underwent an intraperitoneal enteric drained SPK transplant.

Background: Chronic kidney disease (CKD) is a leading cause of death in the United States, and renal fibrosis represents a pathologic hallmark of CKD. Extracellular cold-inducible RNA-binding protein (eCIRP) is a stress response protein involved in acute inflammation, tissue injury and regulated cell death. However, the role of eCIRP in chronic inflammation and tissue injury has not been elucidated.

Renal ischemia-reperfusion (I/R) injury is a common clinical factor for acute kidney injury (AKI). A current study investigated the renoprotective effects of the trinitroglycerine (TNG) combination with chitosan nanoparticles (CNPs) on renal I/R-induced AKI. Rats were randomly assigned to five groups (n = 8/group): Sham, I/R, TNG (50 mg/kg) + I/R, CNPs (60 mg/kg) + I/R, and TNG-CNPs + I/R.

Background And Aims: Image Defined Risk Factors (IDRFs) assess surgical risk in neuroblastoma (NB) and guide neoadjuvant therapy. Despite chemotherapy IDRFs may persist in 70 % of cases. Several studies have suggested that not all IDRFs hold equal significance and that the presence of an IDRF does not inherently signify unresectability.
