National trends of surgery for benign prostatic hyperplasia in Finland

Abstract

<p><strong>Purpose: </strong>To investigate national trends of surgical treatment for benign prostatic obstruction (BPO).</p><p><strong>Methods: </strong>The Care Register for Healthcare in Finland was used to investigate the annual numbers and types of surgical procedures, operation incidence and duration of hospital stay between 2004 and 2018 in Finland. Procedures were classified using the Nordic Medico-Statistical Committee Classification of Surgical Procedures coding. Trends in incidence were analyzed with two-sided Cochran-Armitage test. Trends in duration of hospital stay and patient age were analyzed with linear regression.</p><p><strong>Results: </strong>Transurethral resection of the prostate (TURP) was the most common operation type during the study period, covering over 70% of operations for BPO. Simultaneous with the implementation of photoselective vaporization of the prostate (PVP), the incidence of TURP, minimally invasive surgical therapies, transurethral vaporization of the prostate (TUVP) and open prostatectomies decreased (p < 0.05). The mean operation incidence rate in the population between 2004 and 2018 was 263 per 100,000. The duration of hospital stay shortened (p < 0.05), and the average age of operated patients increased by 2 years (p < 0.0001).</p><p><strong>Conclusion: </strong>The implementation of PVP did not challenge the dominating position of TURP in Finland, but it has probably influenced the overall use of other surgical therapies, excluding transurethral incision of the prostate. The results might suggest that the conservative treatment is accentuated, patient selection is more thorough, and surgical intervention might be placed at a later stage of BPO.</p>
