Is there an option in SAS survey procedures to handle singleton PSUs? The default drops them. Are their options similar to those in stata? I have seen other posts ask this question but have not see an answer. Thanks!

Drops them ???? - all of the data are used for point estimation, but the singleton stratum does not contribute to the variance estimation. With NOCOLLAPSE it does not add a degree-of-freedom either. See Denominator Degrees of Freedom.
What SUDAAN or STATA behavior are you looking for?
