A Study Comparing Urolift and TURP Ahead of Radiotherapy in Men With Urinary Symptoms Secondary to Prostate Enlargement

Prostate cancer affects 1 in 8 men and in the UK approximately 14,000 men are treated with radiotherapy. Around half of men diagnosed with prostate cancer will also have an enlarged prostate making it difficult to pass urine. When having radiotherapy, the prostate swells further which can lead to complete blockage of urine flow (urine retention), sepsis and kidney failure in severe cases. Radiotherapy itself can also cause urinary symptoms meaning that some patients can continue to have difficulty passing urine long after their cancer treatment finishes. Around a third of patients will need an operation to shrink their prostate before radiotherapy to prevent these possible short and long-term problems. The standard operation is a transurethral resection of prostate (TURP). This involves cutting a channel through the prostate to improve urine flow. This will be compared with a newer procedure known as UroLift. During UroLift, clips are inserted into the water pipe to pin back the prostate to widen the channel and improve urine flow. Which treatment is more acceptable to patients and gives better outcomes has never been tested before in men having radiotherapy for prostate cancer. The study will help us to understand how the treatments impact on a patient's quality of life and understand what matters most to patients. The results of this feasibility study will help us design a bigger study to assess TURP and UroLift in a larger group of patients across different hospitals. This research will help future patients make decisions about prostate cancer treatment choices that can affect their long-term well-being.

Male

Inclusion Criteria:

* Men undergoing prostate radiotherapy for prostate cancer
* Patients with moderate to severe and/or bothersome lower urinary tract symptoms secondary to prostate enlargement and/or an obstructive flow rate
* Patients willing and able to provide written informed consent for the study.

Exclusion Criteria:

* Extensive locally advanced disease
* Unfavourable anatomical features (e.g. large middle lobe, for UroLift this requires advanced techniques that have not been fully evaluated in the benign setting(11)
* Prostates over 100g (as per manufacturer's guidelines)
* Co-morbidities precluding surgical intervention
* Prior prostate cancer treatment (including radical prostatectomy, focal therapy i.e. brachytherapy / high intensity focal ultrasound)
* Prior surgical intervention for benign prostatic hyperplasia (including prior UroLift / TURP / other prostate de-obstructing procedures)
* Urinary symptoms not due to prostatic enlargement as primary cause (i.e. neurological disease)
* Patients with complications of prostate enlargement including catheter dependent retention, recurrent urinary tract infections, bladder stones, obstructive uropathy
* Urinary incontinence due to an incompetent sphincter
* Co-existing gross haematuria
* Current active urinary tract infection
