Former US Open champion Stosur knocked out second-seeded Agnieszka Radwanska with a hard-fought 7-5 2-6 6-3 win, while top seed Azarenka made short work of Urszula with a facile 6-1 6-2 triumph.
Stosur needed two and half hours to eventually get the better of her Polish opponent, edging a tight final set which saw her break twice to get over the line.
"I'm obviously very happy with today's win," Stosur said. "To come to a tournament where you weren't expecting to play and decide at the last minute after being given a wild card, it's fantastic to have really made the most of that opportunity and now be in the semis."
But the Australian's semi-final opponent was involved in an even more brutal encounter, France's Virginie Razzano needing over three and a half hours to get past Petra Kvitova.
The three-hour, 35-minute contest was the second-longest on the WTA Tour this year, behind Bethanie Mattek-Sands' three-hour, 42-minute victory over Anastasia Rodionova on the clay courts of Charleston in April.
Razzano took a 5-3 lead in the decising set, but let three match points slip away. Kvitova then served for the match at 6-5, but Razzano broke her to force the decisive tiebreaker which she duly won to complete a remarkable 6-7 (6/8) 7-5 7-6 (10/8) triumph over the third seed.
Things were much more comfortable for Azarenka who breezed past the younger Radwanska sister in just 75 minutes to set up a semi-final date with Ana Ivanovic.
The Serbian former World No.1 booked her place in the last four with a 6-1 6-7 (1/7) 6-2 win over Italy's Roberta Vinci.
