Narrative:
Air carrier X right after takeoff while retracting the gear we had a loss of main hydraulic pressure and a hydraulic fluid loss. Gear would not retract and it was stuck in transit. (Not up or down.) we followed the procedure for hydraulic fluid loss and were able to 'pump' the gear to a down and locked position. I briefed the crew for the landing with no flaps and alerted the ground to have the fire trucks ready. While on approach to landing there was confusion as to what runway tower wanted us to land. At this point in our visual approach we could land on any runway. We could not clear up this confusion with tower because they were busy talking to other aircraft and fire trucks. After about 1 min of trying to communication we were no longer in position to land on the runway they selected. (This runway also had the trucks). I selected to go around and return for another try which was successful. I am not sure what caused the runway confusion but when we contacted tower they should have communicated with us. I think we were priority.

Title: ACR X HYD FAILURE EMER EXTENSION OF LNDG GEAR HAD TO MAKE GAR BECAUSE OF FLC CONFUSION AS TO LNDG RWY.
Narrative: ACR X RIGHT AFTER TKOF WHILE RETRACTING THE GEAR WE HAD A LOSS OF MAIN HYD PRESSURE AND A HYD FLUID LOSS. GEAR WOULD NOT RETRACT AND IT WAS STUCK IN TRANSIT. (NOT UP OR DOWN.) WE FOLLOWED THE PROC FOR HYD FLUID LOSS AND WERE ABLE TO 'PUMP' THE GEAR TO A DOWN AND LOCKED POS. I BRIEFED THE CREW FOR THE LNDG WITH NO FLAPS AND ALERTED THE GND TO HAVE THE FIRE TRUCKS READY. WHILE ON APCH TO LNDG THERE WAS CONFUSION AS TO WHAT RWY TWR WANTED US TO LAND. AT THIS POINT IN OUR VISUAL APCH WE COULD LAND ON ANY RWY. WE COULD NOT CLR UP THIS CONFUSION WITH TWR BECAUSE THEY WERE BUSY TALKING TO OTHER ACFT AND FIRE TRUCKS. AFTER ABOUT 1 MIN OF TRYING TO COM WE WERE NO LONGER IN POS TO LAND ON THE RWY THEY SELECTED. (THIS RWY ALSO HAD THE TRUCKS). I SELECTED TO GAR AND RETURN FOR ANOTHER TRY WHICH WAS SUCCESSFUL. I AM NOT SURE WHAT CAUSED THE RWY CONFUSION BUT WHEN WE CONTACTED TWR THEY SHOULD HAVE COMMUNICATED WITH US. I THINK WE WERE PRIORITY.
