Retrospective analysis of the changes in the surgical treatment of benign prostatic hyperplasia during an 11-year period: a single-center experience

The present study aimed to determine whether the number of patients with symptomatic benign prostatic hyperplasia (BPH) who preferred surgery decreased during the past 11 years at our center (West China Hospital, Chengdu, China), and whether this change affected the timing of surgery and the physical condition of surgical patients. This retrospective study included 57 557 patients with BPH treated from January 2008 to December 2018. Of these, 5427 patients were treated surgically. Surgical patients were divided into two groups based on the time of treatment (groups 8-13 and groups 13-18). The collected data comprised the percentage of all patients with BPH who underwent surgery, baseline characteristics of surgical patients, rehabilitation time, adverse events, and hospitalization costs. The surgery rates in groups 8-13 and groups 13-18 were 10.5% and 8.5% (P < 0.001), respectively. The two groups did not clinically differ regarding patient age and prostate volume. The rates of acute urinary retention and renal failure decreased from 15.0% to 10.6% (P < 0.001) and from 5.2% to 3.1% (P < 0.001), respectively. In groups 8-13 and groups 13-18, the mean catheterization times were 4.0 +/- 1.7 days and 3.3 +/- 1.6 days (P < 0.001), respectively, and the mean postoperative hospitalization times were 5.1 +/- 2.4 days and 4.2 +/- 1.8 days (P < 0.001), respectively. The incidences of unplanned second surgery and death reduced during the study period. The surgery rate decreased over time, which suggests that medication was chosen over surgery. However, the percentage of late complications of BPH also decreased over time, which indicates that the timing of surgery was not delayed.

Automated summary

The study found that the proportion of patients with symptomatic benign prostatic hyperplasia choosing surgery decreased over the past 11 years, but the timing of surgery was not delayed. The incidence of acute urinary retention and renal failure in surgical patients decreased, as did the duration of catheterization and hospitalization postoperatively.
