Background: Erdheim-Chester disease (ECD) is a rare progressive non-Langerhans' cell histiocytic multisystem disorder with a broad spectrum of clinical manifestations, including infiltrative perinephric with ureteral involvement resulting in hydronephrosis, renal atrophy, and eventual renal failure.
Objective: To present a patient with ECD with bilateral renal/ureteral involvement managed with bilateral percutaneous nephrostomy tubes (PCNT) and trametinib who underwent bilateral robotic upper tract reconstruction, the first such published report. The video demonstrates only the left-sided repair, which posed specific challenges and demonstrates reconstructive techniques useful in complex upper tract repairs with limited tissue availability.
A filamentous bacteriophage, designated ϕRs551, was isolated and purified from the quarantine and select agent phytopathogen Ralstonia solanacearum race 3 biovar 2 strain UW551 (phylotype IIB sequevar 1) grown under normal culture conditions. Electron microscopy suggested that ϕRs551 is a member of the family Inoviridae, and is about 1200 nm long and 7 nm wide. ϕRs551 has a genome of 7929 nucleotides containing 14 open reading frames, and is the first isolated virion that contains a resolvase (ORF13) and putative type-2 phage repressor (ORF14).
