Researchers have identified independent factors associated with early recovery of urinary continence after robot-assisted radical prostatectomy (RARP). These factors include lower preoperative PSA values, higher Sexual Health Inventory for Men (SHIM) score, and shorter operative time.

Investigators at The Cancer Institute of New Jersey, Robert Wood Johnson Medical School, in New Brunswick, studied 380 men who underwent RARP for localized prostate cancer. The researchers, led by Isaac Yi Kim, MD, Chief, Section of Urologic Oncology, divided the men into three groups: those who became continent within one week after urinary catheter removal (group I, 93 patients, mean age 58.4 years); patients who gained continence between one week and three months (group II, 220 patients, mean age 59 years); and subjects who became after three months (group III, 67 patients, mean age 61 years).

The investigators defined continence as being pad-free. Patients in groups I, II, and III had mean preoperative PSA levels of 5.62, 5.79, and 7.22, respectively, Dr. Kim’s group reported at the World Congress of Endourology in Chicago. The groups had mean SHIM scores of 18.4, 18.0, and 15.4, respectively. The mean operating time was 189, 204, and 221 minutes, respectively. For all of the parameters, groups I and II differently significantly from group III in multivariate analyses, the investigators noted.
