For urinary tract symptoms, all questions in USSQ were used
p* for comparisons between PSS and baseline (double-pigtail stent) in group 1
p** for comparisons between PSS and baseline (no stent) in group 2
p*** for comparisons between the two groups, for the PSS
p**** for comparisons between control group and baseline (double-pigtail stent) in group 1
