Sequence generation {16a}
After informed consent is obtained and just past baseline visit, patient will be randomized into a sling and no sling groups. To allocate patients into the two groups, the investigators will use a computer-generated list of random numbers with an allocation of 1:1 using block sizes of four or six using R (version 3.6.2, R Foundation for Statistical Computing, Vienna, Austria). No stratification techniques will be used in the randomization process.
