Purpose: To investigate the influences of preoperative bladder outlet obstruction(BOO) to be adjusted by age and prostate volume on improvement of storage symptoms in patients who underwent transurethral resection of prostate(TURP) in a long term follow up.
Materials and Methods: We performed retrospective study of 75 patients with benign prostatic hyperplasia(BPH) who had undergone TURP and preoperative urodynamics from July 2004 to December 2006. 18 patients of them were lost follow up in this period, so we analyzed 57 patients in this study. The degrees of BOO were measured by the Abrams-Griffiths (AG) number calculated according to the preoperative urodynamic data. International Prostate Symptom Score(IPSS) questionnaire were used to evaluate improvement of symptoms. Especially IPSS questions number 2, 4 and 7 were used to evaluate storage symptoms. Partial correlation analysis was done between the AG numbers and the degree of storage symptoms improvement, adjusted by the age and the prostate volume.
Results: There were significant decreases of the IPSS(p=0.029), storage symptom score(p=0.024) and frequency score(p=0.017) in BOO group compared to the non-BOO group. The changes of IPSS(?=?0.338, p=0.012), storage symptoms score(?=?0.292, p=0.031) and frequency symptom score (?=?0.305, p=0.023) were significantly correlated with AG number.
Conclusions: These results suggested that the preoperative AG number derived from urodynamics was an important factor in predicting the postoperative results. It would be expected that the patients with high AG numbers might be more improved storage symptom after TURP.
