Plain English summary of protocol
Background and study aims:
Rectal resection surgery is an operation to remove part or all of the rectum (the final part of the large intestine, ending in the anus). It is usually performed on patients with serious medical conditions such as rectal cancer or ulcerative colitis (a condition that causes long-term swelling (inflammation) in the large intestine and rectum). Urological (relating to urination) and sexual dysfunction are common after rectal resection surgery. This is mainly due to damage to the nerves in the pelvis during the surgery. Robotic surgery allows for precision surgery in the pelvis and can enable better preservation of those nerves. This could therefore ultimately lead to better preservation of function after rectal surgery. The aim of this study is to test find out whether robotic rectal surgery offers better urological and sexual functional outcomes when compared to standard laparoscopic (keyhole) surgery.
Who can participate?
Male sexually active adult patients requiring rectal resection surgery.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group undergo rectal resection surgery using the robotic method. Those in the second group undergo rectal resection surgery using the laproscopic method. Before surgery and then three, six and twelve months later, participants in both groups complete questionnaires about their sexual and urological function.
What are the possible benefits and risks of participating?
There are no benefits or risks involved with participation to this study. However, the results of this study could benefit others in the future.
Where is the study run from?
1. Poole Hospital (UK)
2. Frimley Park Hospital (UK)
3. Leeds Teaching Hospitals (UK)
4. Champalimaud Clinical Centre (Portugal)
When is the study starting and how long is it expected to run for?
February 2016 to February 2019

| Scientific title | Urological and sexual function in males following robotic vs laparoscopic rectal surgery: An international, multicentre, randomised control trail |
| Study acronym | UROLE |
| Study objectives | The aim of this study is to evaluate the difference in urological and sexual function following two methods of minimally invasive rectal resectional surgery (robotic rectal surgery versus laparoscopic surgery). |
| Ethics approval(s) | East of England - Cambridgeshire and Hertfordshire Research Ethics Committee, 20/01/2017, ref: 16/EE/0492 |
| Health condition(s) or problem(s) studied | Specialty: Surgery, Primary sub-specialty: General Surgery; UKCRC code/ Disease: Oral and Gastrointestinal/ Other diseases of the digestive system |
| Intervention | Following provision of informed consent, participants are randomised to one of two groups. Stratified randomisation will take place through the use of previously filled opaque concealed envelopes. Stratification will be based on whether patients have received pre-operative chemoradiotherapy or not. An equal number of patients will be randomised for each arm. Previously filled opaque concealed envelopes will ensure concealed allocation. To ensure true randomisation envelope sequence will have been generated by a random computer-generated number sequence Group 1: Participants receive robotic rectal surgery. This involves rectal resection surgery with a robotic surgical system platform. Group 2: Participants receive laparoscopic rectal surgery. This involves involves rectal resection surgery via means of laparoscopic instruments. In both groups, surgery will take place at the operating room as per unit protocol and performed by the consultant surgeon. Participants will undergo a urodynamic assessment in first instance in the outpatients clinic by the research nurse or fellow and again during colorectal surgery post-operative follow up clinics. Following surgery, the participants in both groups will receive standard post-operative care as per unit's standard practice. Outcome measures will be assessed at 3, 6 and 12 months following surgery. This will coincide with routine post-operative surgical follow up appointments. |
| Intervention type | Other |
| Primary outcome measure | 1. Urological function is measured using the International Prostatic Symptoms Score (IPSS) pre-operatively and 3, 6 and 12 months after surgery 2. Sexual function is measured using the International Index of Erectile Function (IIEF) pre-operatively and 3, 6 and 12 months after surgery 3. Urodynamics (urine flow rate and post micturition residual urine volume) are assessed by a uroflow meter and a bladder scanner pre-operatively and 3, 6 and 12 months after surgery |
| Secondary outcome measures | No secondary outcome measures |
