Study summary

This registry study aims to collect data on efficacy and safety of different treatments of benign prostatic enlargement (BPE) and lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH-LUTS).

Read the detailed description

This registry study aims to collect data on efficacy and safety of different treatments of benign prostatic enlargement (BPE) and lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH-LUTS).

Clinical, patient reported and imaging data that are assessed in clinical routine will be prospectively collected. All patients that are treated for BPE / BPH-LUTS at our institution will be included if they provide written informed consent.

This registry enables us to compare novel treatment option (e.g. prostatic artery embolization; PAE) to established interventions (e.g., TURP, HoLEP, open prostatectomy, ThuLEP, Thulium laser vaporization, TUIP) regarding safety and efficacy.

Inclusion criteria

  • All patients treated for BPH / LUTS / prostatic obstruction at the urological department of KSSG
  • Patient age ≥ 18 years
  • provided

Exclusion criteria

Exclusion Criteria:

-Cognitive impairment not allowing or adequate data assessment.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
