Preop Laxatives in Robotic Urologic Surgery
Study Details
Study Description
Brief Summary
Minimally-invasive surgery, either laparoscopic or robotic, is commonly used in urology. Several urologic procedures including prostatectomy, radical nephrectomy, and partial nephrectomy are now commonly performed robotically. Patients undergoing these procedures often have delayed return of bowel function and persistent gastrointestinal symptoms including nausea/vomiting, abdominal distension, and bloating for several days to weeks after surgery. Postoperative stool softeners and laxatives are routinely used in an effort to minimize these symptoms, with varying degrees of success. The aim of this study will be to evaluate whether the use of a preoperative osmotic laxative will be beneficial in improving recovery of bowel function and alleviating postoperative gastrointestinal complaints in patients undergoing these procedures. Patients will be randomized to either receive or not receive three days of polyethylene glycol (PEG, also known as MiraLAX) on the three days before surgery. Patients in both groups will receive the same postoperative bowel regimen including scheduled PEG both in the hospital and upon discharge until first bowel movement. Patients will be given a questionnaire and diary to record their postoperative gastrointestinal symptoms and time to first bowel movement. These questionnaires and diaries will then be analyzed to determine differences in time to first bowel movement and gastrointestinal complaints during their recovery from surgery.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Control Do not receive polyethylene glycol before surgery |
|
| Experimental: Intervention Receive polyethylene glycol before surgery |
Drug: Polyethylene Glycol 3350
Patients in the intervention arm will take polyethylene glycol 3350 for three days before robotic urologic surgery. Patients in the control arm will not.

Outcome Measures
Primary Outcome Measures
- Time to first bowel movement after surgery [7 days]
Time to first bowel movement after surgery
Secondary Outcome Measures
- Narcotic usage [7 days]
Morphine equivalents used by patients in the first 7 days postoperatively
- Patient Assessment of Constipation-Symptoms (PAC-SYM) Questionnaire [7 days]
Patient Assessment of Constipation-Symptoms (PAC-SYM) Questionnaire scores 7 days postoperatively (scale 0 - 48, higher score indicates worse constipation)
