Benign Prostate Hyperplasia (BPH) is a long-term and progressive condition, resulting in lower urinary tract symptoms (LUTS), which have a negative impact on a patient’s quality of life and are associated with a considerable burden on NHS resources.

The UroLift® System is a proven treatment, which is recommended by NICE as a cost saving alternative to current surgical options. UroLift uses adjustable, permanent implants to pull excess prostatic tissue away so that it does not narrow or block the urethra. It is designed to relieve symptoms of urinary outflow obstruction without cutting or removing tissue. The Urology team at Norfolk and Norwich University Hospitals NHS Trust (NNUH) were aware of the evidence for UroLift and good outcomes experienced by other trusts, and were keen to evaluate the role of UroLift in creating an ambulatory treatment option for patients who require surgery for LUTS.

Aims and objectives

Aim: To introduce an ambulatory surgical treatment option for men with LUTS from BPH, guided by NICE recommendations.

Objectives:

  • Increase theatre capacity and reduce pressure on inpatient beds, thereby reducing pressure on waiting times
  • Offer greater treatment choice to men requiring surgery for LUTS from BPH
  • Reduce complications from existing surgical intervention for LUTS from BPH

Reasons for implementing your project

NNUH is a large teaching hospital with a busy Urology department. It has a tertiary catchment area of over 800,000 patients and a large elderly population. It performs 350-400 bladder outlet obstruction procedures each year, and has significant and increasing pressure on waiting times for urological procedures, especially for cancer, where volume is high.

There is an urgent need to free up theatre capacity and inpatient beds. The current standard of surgical care offered to men with LUTS from BPH at NNUH is either transurethral resection of the prostate (TURP) or holmium laser enucleation of the (HoLEP). NNUH performs around 200 TURP procedures each year, with an average length of stay of 3 days. It performs around 100 HoLEP procedures each year, and patients are normally discharged the same day with a catheter.

TURP and HoLEP are both performed under a general anaesthetic and take up an average of 56 and 72 minutes of theatre time (patient turnaround time) respectively. While both TURP and HoLEP are effective at relieving the symptoms of LUTS, they can be associated with significant post-operative complications, including bleeding, infection and incontinence, which can prolong length of stay and delay recovery, and can also require further intervention, Permanent side effects can include sexual dysfunction and urinary incontinence.

TURP and HoLEP also necessitate the use of a catheter after the procedure (often for several days after a TURP) increasing the risk of urinary tract infection UroLift presented an opportunity to employ an ambulatory and minimally invasive procedure to treat a large proportion of patients who require surgery for LUTS from BPH. In addition to reducing the length of stay and theatre time, UroLift is also associated with a significantly reduced risk of permanent side effects and serious complications, compared with TURP and HoLEP.

NICE suggests that UroLift will help improve productivity through reduced post-discharge follow-up both in primary care and outpatient settings. UroLift also does not require the patient to be catheterised, therefore reducing the risk of catheterisation-associated UTI. As a short, ambulatory procedure, performed under a local anaesthetic, UroLift provided the opportunity for more efficient use of the Day Procedure Unit at NNUH.


How did you implement the project

In January 2015, a business plan was developed and taken through usual Trust business planning process. The focus of the business case was reduction in inpatient bed days, theatre hours, waiting times and cost savings.

A particular point of interest was savings that could be made from the avoidance of fines for waiting time breaches. UroLift was approved by the New Procedures Committee in August 2015, and by the Divisional Board in October 2015, following funding negotiation with commissioners.

NNUH offers a ‘one-stop’ urology clinic, which provides comprehensive assessment of patients with urological symptoms. At this clinic, a history is taken, the patient is examined and prostate symptoms are assessed using the International Prostate Symptom Score (IPSS) questionnaire. Flow rate and residual volume are measured and patients with LUTS undergo a flexible cystoscopy to determine suitability for different surgical options.

Once a full assessment is complete, patients are counselled on the different treatment options and patient information sheets are provided. Patients leave the clinic with a management plan, which may include surgery as an option.

The first patients to be treated with UroLift were identified through a series of four dedicated one-stop LUTS clinics, which were run over November and December 2015. Clinical training for UroLift and case observation took place and in January 2016 the first UroLift procedures were performed.

Patients requiring surgery for LUTS are offered a choice of surgical options, which now include UroLift. The majority of patients requiring surgical intervention for their BPH symptoms would be clinically eligible for UroLift, however some patients would not be considered suitable due to the size of their prostate (over 100ml) or the presence of an obstructive median lobe.

UroLift procedures are performed in the Day Procedure Unit. Initially these were performed under a general anesthetic, but as confidence of the surgeon in the procedure grew, local anaesthetic (instillagel +/- propofol) was introduced and is now routine, with very occasional light sedation if required. Two to four UroLift implants are used, depending on the size of the prostate. No catheter is used and patients are discharged as soon as they have voided – normally after a couple of hours. No routine discharge medication is prescribed. Patients are followed up by telephone with a symptom score measure at 3 months.


Key findings

Over 72 patients have been treated with UroLift. In the majority of these patients, local anaesthetic was used and is now routine. The results of a recent audit are shown in the table below.

In this cohort, the average number of implants required per patient was 2.6. However, during this early part of our learning curve, we tended to recruit patients with smaller prostates, who required fewer implants.

We currently offer UroLift to patients with prostates up to 100ml and requirement overall is up to 4 implants per patient. Complications are very rarely seen and are very minor compared with the number and severity of complications routinely reported with TURP. At the 3 month follow-up, patients had significant improvements in the key clinical parameters, including IPSS, quality of life scores, urinary flow rate (Qmax) and post-void residual volume (RV).

Encouragingly, improvements in the average IPSS mirrored that observed at 3 months in clinical trials with UroLift. The team concluded that UroLift is an effective treatment option for men requiring surgery for LUTS from BPH. The UroLift procedure is straightforward and easy to learn, without requirement for additional resources apart from the UroLift implants themselves. It can be easily performed under a local anesthetic, enabling quick turnaround in theatre.

Procedure time (patient turnaround time) is 25 mins, and 7-8 cases can be done in an afternoon list. Recovery is quick and the side effects and complex complications commonly associated with other surgical interventions are avoided. Unlike other surgical options for LUTS, UroLift is a true ambulatory procedure, where patients are discharged without a catheter after only a few hours and require minimal follow-up.

Analysis of the cases performed to date concluded that UroLift is a cost effective treatment, compared with other surgical options, and we expect it to provide significant efficiency and productivity savings by reducing inpatient bed stay, theatre time and follow-up. For the future role of UroLift, the team are considering moving the procedure out of the day unit into an ambulatory setting, which would relieve pressure on the Day Procedure Unit. Also the procedure may lend itself to a ‘see and treat’ pathway whereby patients are assessed and treated in the same day, which would provide further efficiency savings.


Key learning points

• Commence funding discussions with commissioners as early as possible and involve department Business Manager for support and in development of business case. • The business case should take into consideration that most men with lower urinary tract symptoms (not in retention) and obstructing flow rate are candidates for UroLift. These men will have a prostate size of <100ml and will have no significant median lobe. The average number of implants required is less than 4, however, many patients require 2 or 3. Occasionally, with a large prostate, 5 or 6 implants are required. • Training should follow the manufacturer’s rigorous format to ensure best clinical outcomes. • Surgeons may want to perform initial cases under a general anaesthetic until they are confident with the procedure. After this, the procedure can easily be performed under a local anaesthetic, or light sedation if required. • Data collection and audit is very important to demonstrate patient outcomes and benefits, as well as efficacy savings. • Assessment of patients is best carried out in a one-stop clinic, with access to cystoscopy, in order to limit patient visits.
