ABSTRACT
<p><b>Objective</b>To evaluate the effect and safety of phloroglucinol combined with parecoxib on cystospasm after transurethral resection of the prostate (TURP).</p><p><b>METHODS</b>We conducted a prospective randomized case-control study on 98 patients treated by TURP. After operation, the patients were randomly assigned to a treatment (n=50) and a control group (n=48), the former treated by intravenous injection of 80 mg phloroglucinol qd plus 40 mg parecoxib bid while the latter given 80 mg phloroglucinol only, both for 3 successive days. Then we recorded the frequency and duration of cystospasm, visual analogue scales (VAS), adverse reactions, post-operative bladder irrigation time, catheter-indwelling time, and hospital stay and compared them between the two groups of patients.</p><p><b>RESULTS</b>Compared with the controls, the patients in the treatment group showed a significantly lower frequency of cystospasm (［1.95±0.14］ vs ［0.70±0.65］ times, P<0.01), duration of cystospasm (［0.44±0.21］ vs ［0.12±0.14］ min, P<0.01), and VAS score (2.70±1.80 vs 1.90±1.30, P<0.01) at 48－72 hours after TURP, but no statistically significant differences were found between the control and treatment groups in the post-operative bladder irrigation time (［2.75±0.87］ vs ［2.64±0.83］ d, P>0.05), catheter-indwelling time (［3.52±0.32］ vs ［3.44±0.42］ d, P>0.05), and hospital stay (［5.23±0.81］ vs ［5.10±0.73］ d, P>0.05), and no obvious adverse reactions were observed in either of the two groups.</p><p><b>CONCLUSIONS</b>Phloroglucinol combined with parecoxib is more effective and safer than phloroglucinol alone in relieving postoperative cystospasm after TURP.</p>
