Patient-reported Pain and Symptom Relief During Three Months After Surgery for Benign Prostatic Hyperplasia

Patient-reported Pain and Symptom Relief During Three Months After Surgery for Benign Prostatic Hyperplasia.

This is a prospective observational study in patients undergoing surgery for benign prostatic hyperplasia (BPH).

The purpose of the study is to investigate in great detail patients' recovery after surgery for BPH regarding pain, hematuria, urine leakage and use of pain-relieving medications for three months postoperatively. Patient-reported outcomes after three different surgical methods will be investigated: transurethral resection, transurethral vaporization and laser transurethral enucleation of the prostate (Green-LEP)

Research questions:

• How do patients rate their day-to-day pain during the first three months after surgery for BPH? How long does it take to be pain free?
• How does the patient estimate any day-to-day burning sensation during the first three months after surgery for BPH?
• How many painkilling tablets of a certain preparation and a certain strength take patients per day in the first three months after surgery for BPH?
• How long do patients have urinary leakage after surgery for BPH?
• Are the patients bothered by possible urine leakage and if so for how long after surgery for BPH?
• How long does one have macroscopic hematuria after surgery for BPH?
• How quickly are the patients' urinary tract problems affected according to the IPSS per month?
• Are the results on the above outcome measures different between the three TUR-P methods, TUV-P and Green LEP?

Design and selection:

This is a prospective multicenter observational study in which patients undergoing TUR-P, TUV-P and GreenLEP for BPH are included. The subjects will be followed up with a self-assessment form that is completed daily for three months and then sent to the responsible researchers. After this, the research subjects will be followed up with sent out IPSS forms after six months, and then annually for up to five years. These are sent in stamped envelopes.

Participants:

The study will include 500 patients who undergo surgery for BPH at Alingsås hospital, Sjukhusen i Väster and Sahlgrenska University Hospital, as well as possibly an additional urology clinic in the future. The inclusion criteria include men over 50 years of age with diagnosed BPH and LUTS who have an indication for surgery with any of the three methods studied.

Outcome measures:

1. Pain and burning will be assessed using the NRS (numeric scale) between 0 and 10 where 0 is defined as "no pain/burning" and 10 is defined as "worst imaginable pain/burning". The researchers fill in this day-by-day for three months
2. Use of pain-relieving medications will be investigated with a table in which the research subjects enter drug names and sum up the number of tablets taken per day.
3. Urine leakage will be examined by the research subjects checking either "Yes" or "no" on the question of whether they have had urine leakage on a daily basis.
4. If this urine leakage has bothered the research subjects, it is investigated by ticking either "Yes" or "No" daily as a follow-up question to the previous one.
5. The duration of hematuria will be examined by the research subjects checking either "Yes" or "No" on the question of whether they have had blood in the urine daily
6. The change in LUTS measured by IPSS will be used to measure patient-perceived outcomes at baseline, after four, eight and twelve weeks, after six months and then annually for five years.

Data Analysis:

Descriptive statistics will be used to compile the PROMs data. Changes over time will be analyzed using repeated measures (ANOVA). Differences in outcome measures between the three different methods will be analyzed with the Mann-Whitney test for continuous, independent data pairs, and the Chi-Square test for categorical variables.

Ethical considerations:

The study will be conducted in accordance with the Declaration of Helsinki, and all participants will give their informed consent. Ethical approval will be sought from the Ethical Review Authority (EPM)

Significance and clinical relevance:

The results of this study will provide important insights into how patient-reported outcomes after benign prostate surgery can be used to improve surgical outcomes and patient counseling. The results will also be able to be used to compare outcome measures between the three different treatments used for BPH. By highlighting the patient's perspective, care can be developed to better meet the patients' needs and expectations, and by determining a "normal course" regarding these outcome measures, the results can also be used in the future to identify patients who deviate from the expected recovery course.

Inclusion Criteria:

• Patients undergoing transurethral surgery for benign prostatic hyperplasia
