Narrative:

Climbing out of approximately 15;000 ft at about 300-315 KTS had left hydraulic qty and left hydraulic system press EICAS messages. We went to status page and left hydraulic quantity showed 0.00RF. Performed loss of hydraulics for left system and turned off both left pumps (engine driven and electric). Left system pressure on status page showed between 3050 and 3450 psi (ptu pressure?). [We] reviewed systems with first officer including rudder ratio and yaw damper malfunctions. Continued onto [our destination] and climbed to FL370. On arrival swapped duties with first officer and flew the STAR and localizer xxl. [We] started lowering flaps early. Got flaps to 20. Upon lowering gear got a gear disagree and I think at this time the power xfer unit status message occurred. Did alternate gear extension and then tried to lower flaps further. [We] received a te disagree message. At this time we were about 800 ft and performed a go around. Completed checklists; came around and landed on [runway] xxc. [We] cleared to the left on the high speed. After clearing we stopped and were towed in.not much we could do to prevent the breakdown. In hindsight though; I should have declared an emergency. After the go around with the gear stuck down and the flaps at 20 we were going the wrong way burning 11;000 pounds/hour. Once requesting a turn downwind ATC was very accommodating and helped out by offering the center runway. First officer was tremendous help.

Title: A B757-200 flight crew elected to continue to their destination after the left hydraulic system failed as they climbed through 15;000 FT after takeoff. Problems extending both the flaps and landing gear at their destination forced a go around and completion of associated abnormal procedure checklists. After landing they were towed to the gate.

Narrative: Climbing out of approximately 15;000 FT at about 300-315 KTS had L HYD QTY and L HYD SYS PRESS EICAS messages. We went to Status page and left hydraulic quantity showed 0.00RF. Performed loss of hydraulics for left system and turned off both left pumps (Engine Driven and Electric). Left system pressure on status page showed between 3050 and 3450 PSI (PTU pressure?). [We] reviewed systems with First Officer including Rudder Ratio and Yaw Damper malfunctions. Continued onto [our destination] and climbed to FL370. On arrival swapped duties with First Officer and flew the STAR and LOC XXL. [We] started lowering flaps early. Got flaps to 20. Upon lowering gear got a GEAR DISAGREE and I think at this time the POWER XFER UNIT Status message occurred. Did alternate gear extension and then tried to lower flaps further.
