Abstract
Objectives
Transurethral resection of prostate (TURP) and laser prostate surgery are common surgeries for benign prostate hyperplasia (BPH). We conducted an investigation using hospital
database to evaluate the clinical factors associated with post-operative usage of alphablockers and antispasmodics.
Methods
This study was conducted using retrospective clinical data from the hospital database,
which contained newly diagnosed BPH patients between January 2007 and December
2012 who subsequently received prostate surgery. The study end-point was the use of
alpha-blockers or antispasmodics for at least 3 months duration after 1 month of surgery.
The exclusion criteria was prostate cancer diagnosed before or after the surgery, recent
transurethral surgeries, history of open prostatectomy, and history of spinal cord injury. Clinical parameters, including age, body mass index, preoperative prostate specific antigen
value, comorbidities, preoperative usage of alpha-blockers, anstispasmodics and 5-alpha
reductase inhibitors, surgical methods, resected prostate volume ratios, and preoperative
urine flow test results, were evaluated.
Results
A total of 250 patients receiving prostate surgery in the database and confirmed pathologically benign were included. There was significant association between chronic kidney disease (CKD) and the usage of alpha-blockers after prostate surgery (OR = 1.93, 95% CI

1.04–3.56, p = 0.036). Postoperative antispasmodics usage was significantly associated
with preoperative usage of antispasmodics (OR = 2.33, 95% CI 1.02–5.36, p = 0.046) and
resected prostate volume ratio (OR = 0.12, 95% CI 0.02–0.63, p = 0.013).
Conclusions
BPH patients with underlying CKD were more likely to require alpha-blockers after surgery.
In the meantime, BPH patients who required antispasmodics before surgery and who
received lower prostate volume resection ratio were more liable to antispasmodics after
prostate surgery.
Introduction
Benign prostate hyperplasia (BPH) is a common problem in elder patients, with a prevalence
of over 50% in male population aged over 50 years [1]. BPH may lead to prostate enlargement
that obstructs bladder neck, which further causes lower urinary tract symptoms (LUTS).
Symptomatic LUTS can be manifested as storage symptoms and voiding symptoms, and may
result in decreased quality of life as well as various complications [2]. Treatment of BPHinduced LUTS is indicated to relieve symptoms and prevent complications. The treatment
begins with lifestyle modification and medical treatment, and may proceed to surgical intervention if initial treatments fail. Most patients present with general improved LUTS symptoms
after surgery [3,4]. However, some patients still require medical treatment, especially adrenergic alpha-blockers and antispasmodics, after surgery due to recurrent BPH or persistent LUTS
symptoms [5,6]. Obviously, there may be some different characteristics in this patient group
that hinder the effects of surgical interventions. Further investigation of this patient group is
essential to provide better treatment suggestion in advance. In this study, we aim to identify
BPH patients who require adrenergic alpha-blockers and antispasmodics for at least three
months after receiving surgery using preoperative and perioperative data.
Methods
Database
Our database was a web-based system that recorded clinical information of patients receiving
medical care in Taichung Veterans General Hospital (VGHTC) since January 2000. It included
diagnosis, operation notes, results of examinations from outpatient departments, emergency
departments and hospitalizations, as well as records of prescribed medicine. The patient data
was de-identified before our analysis for privacy concern.
Patient selection and treatments
Patients who were newly diagnosed BPH between January 2007 and December 2012, and subsequently received prostate surgery were included. The ICD code for BPH was ICD-9-CM
600. The exclusion criteria included prostate cancer diagnosed before or after surgery, transurethral incision or resection within a year before surgery, history of open prostatectomy, and
history of spinal cord injury. History of prostate cancer was identified by medical records, preoperative transurethral biopsy results, and biopsy retrieved peri-operatively. All patients
included were followed up to December 2021 for last hospital visit or death.

Study process
This study was conducted using retrospective clinical data from VGHTC database, and was
approved by institutional review board with No. CE21221A. The study endpoints included the
usage of adrenergic alpha-blockers and antispasmodics after surgery for at least three months.
Most patients returned back to the outpatient clinic one week after discharge and were followed up every three months afterward. The cut-off of minimum three m (...truncated)
