This study is designed to assess the effect of catheter size on postoperative catheter pain, urinary continence, urinary flow rates, post void residuals, International Prostate Symptom Scores (IPSS), and Quality of Life (QoL) score, as well as long term complications after robotic assisted laparoscopic prostatectomy.
Subjects identified to receive a robotic assisted laparoscopic prostatectomy.were randomized to either a 16 French or 20 French catheter at the completion of the prostatectomy. All prostatectomies were performed by one of three surgeons at the investigator's institution. Preoperative demographics and operative data were recorded for each group. Catheters remained in place for 7-14 days. Subjects were asked on postoperative day 7 to report their catheter-related pain and amount of opioid medication used. Urinary symptoms and quality of life scores and pads per day were recorded at 6 weeks and 12 weeks post-operatively.

Catheter Related Pain: Visual Analog Score Rating
Catheter related pain was measured using a visual analog score rating mean post-operative pain on a scale from 1 (no pain) to 10 (worst possible pain). The lower the score the better the outcome.
Time frame: post-op day 5-7
Urinary Symptoms
The International Prostate Symptom Score (I-PSS) is based on the answers to seven questions concerning urinary symptoms and one question concerning quality of life. Each question concerning urinary symptoms allows the patient to choose one out of six answers indicating increasing severity of the particular symptom. The answers are assigned points from 0 to 5. The total score can therefore range from 0 to 35 (asymptomatic to very symptomatic).The lower the score the better the outcome.
Time frame: week 6
Quality of Life Score
Question eight of IPSS refers to the patient's perceived quality of life. The range is from delighted with a score of zero to terrible with a score of 6. The lower the score the better the outcome.

Time frame: Week 12
Opioid Use
Patient reported use of the number of tablets taken from provided prescription of opioids for post-operative pain. This will be converted to a standardized morphine equivalency for comparison. The lower the value the better the outcome.
Time frame: after discharge until post-op day 7
Home Opioid Use in Standard Morphine Equivalency
Patient reported use of the number of tablets taken from provided prescription of opioids for post-operative pain. This will be converted to a standardized morphine equivalency for comparison. The lower the value the better the outcome.
Time frame: after discharge until post-op day 7
Number of Incontinence Pads Used
Patient reported number of incontinence pads used per day. The lower the number the better the outcome.
Time frame: week 6
Patient Reported Number of Pads Used Per Day.
Patient reported number of incontinence pads used per day. The lower the number the better the outcome.
