Laparoscopic radical nephroureterectomy: results of an international multicenter study.
Hazem Abou El Fettouh,Jens Rassweiler,Michael Schulze,Laurent Salomon,James Allan,Sanjay Ramakumar,Thomas W. Jarrett,Claude C. Abbou,David A. Tolley,Louis R. Kavoussi,Inderbir S. Gill +10 more
TL;DR: Laroscopic radical nephroureterectomy appears to be an effective minimally invasive treatment for select patients with upper tract transitional cell carcinoma, and longer follow-up is needed before laparoscopy can be considered as a standard treatment.

Local hemostasis during laparoscopic partial nephrectomy using biodegradable hydrogels: Initial porcine results
Sanjay Ramakumar,William W. Roberts,Oscar Eduardo Hidetoshi Fugita,Peter Colegrove,Theresa M. Nicol,Thomas W. Jarrett,Louis R. Kavoussi,Marvin J. Slepian +7 more
TL;DR: This study examined the novel strategy of forming occlusive tissue-adherent hydrogels utilizing a synthetic biodegradable polyethylene glycol-lactide copolymer (PEG- lactide) as an in situ occlusion barrier for hemostasis and wound control during laparoscopic urologic procedures.

Multicentric papillary renal carcinoma in renal allograft
TL;DR: It is speculated that the allograft in this case is predisposed to malignant changes because of preexisting genetic mutations, as well as prolonged immunosuppression.

Novel delivery of oligonucleotides using a topical hydrogel tissue sealant in a murine partial nephrectomy model
Sanjay Ramakumar,Hardeep Phull,Todd Purves,Joel Funk,Duan C. Copeland,Judith B. Ulreich,Li Wen Lai,Yeong Hau Howard Lien +7 more
TL;DR: A novel murine partial nephrectomy model was successfully created using PEG hydrogel that served as a successful depot for delivering oligonucleotides throughout the kidney and provided adequate protection against renal hematoma and intraperitoneal blood.

Delivery of intercellular adhesion molecule-1 antisense oligonucleotides using a topical hydrogel tissue sealant in a murine partial nephrectomy/ischemia model.
Hardeep Phull,Yeong Hau H. Lien,Mohamed W. Salkini,Christina Escobar,Li Wen Lai,Sanjay Ramakumar +5 more
TL;DR: It is shown that polyethylene glycol (PEG) hydrogel, which also functions as a tissue sealant, is an effective topical delivery vehicle for oligonucleotides in a murine partial nephrectomy model and holds potential for a highly specific, localized method of preventing tissue damage after ischemia/reperfusion injury.
