RESUMEN
<p><b>OBJECTIVE</b>To explore the lower urinary tract symptoms (LUTS), especially those in the urinary storage phase, following transurethral resection of the prostate (TURP), and to improve the postoperative management and patients' quality of life after TURP.</p><p><b>METHODS</b>A total of 86 patients with benign prostate hyperplasia (BPH) underwent TURP, and were interviewed on urinary symptoms at 1, 3, 7, 15 and 30 days after removal of the catheter. The patients were divided into two groups according to whether they had preoperative detrusor instability and/or compliance of the bladder (Group A) or not (Group B), and observed for the changes in IPSS scores and urinary storage symptoms after removal of the catheter.</p><p><b>RESULTS</b>Complete follow-ups were achieved in 71 cases, 28 with detrusor instability and/or compliance of the bladder and the other 43 without. Their IPSS scores on the 1st, 3rd, 7th, 15th and 30th day after removal of the catheter were 8.1 +/- 2.5, 7.2 +/- 3.1, 6.3 +/- 3.8, 5.3 +/- 4.2 and 2.4 +/- 3.4, respectively, with statistically significant differences between the 7th and the 1st as well as the 30th and the 15th day (P < 0.05), but not between the 1st and the3rd nor the 15th and the 7th day (P > 0.05). On the 1st day, the cardinal symptoms in the urinary storage phase were urinary frequency, urgency and incontinence; the scores on IPSS and urinary storage symptoms were 10.4 +/- 3.3 and 9.3 +/- 3.8 in Group A and 6.2 +/- 2.8 and 5.2 +/- 2.7 in Group B, with significant differences between the two groups (P < 0.05). After treatment with tolterodine and alpha-adrenoreceptor inhibitor, neither IPSS scores nor the scores on urinary storage symptoms showed any significant differences between Groups A and B on the 15th and 30th day (P > 0.05).</p><p><b>CONCLUSION</b>The lower urinary tract symptoms following TURP, especially those in the urinary storage phase, are correlated with preoperative bladder function, and getting improved gradually after surgery.</p>
