RESUMEN
<p><b>OBJECTIVE</b>To evaluate the efficacy of phloroglucinol in preventing bladder spasm after transurethral resection of the prostate (TURP).</p><p><b>METHODS</b>Using the random sampling method, we assigned 74 cases of TURP into a treatment group (n = 39), given 80 mg phloroglucinol every day for 3 days, and a control group (n = 35), left untreated. Then we observed the frequency, duration and pain of bladder spasm within the 3 days and compared them between the two groups.</p><p><b>RESULTS</b>The mean frequency, duration and pain visual analogue score of bladder spasm were (4.3 +/- 1.2) times, (7.2 +/- 2.1) min and 3.2 +/- 1.6 respectively in the treatment group, as compared with (7.5 +/- 2.4) times, (15.6 +/- 6.8) min and 4.7 +/- 2.3 in the control, with statistically significant differences between the two groups (P < 0.05). And no obvious adverse reactions were found in the treatment group.</p><p><b>CONCLUSION</b>Phloroglucinol is safe and effective for the prevention and treatment of bladder spasm following TURP.</p>
