Prospective evaluation of an intraoperative urodynamic stress test predicting urinary incontinence after robot-assisted laparoscopic radical prostatectomy.

A sufficient IST, as a surrogate variable for a fully obtained rhabdomyosphincter, has no significant predictive value on its own but seems to be the optimal prerequisite for continence, since the data shows that the lack of neurovascular supply required for a functioning sphincter leads up to a 3.1 times higher risk for PPI.
