PURPOSE: We evaluated the factors that affect the improvement of the initial peak flow rate after transurethral resection of the prostate (TURP) or photoselective vaporization of the prostate ( @entity12468 ) for @entity1067 ( @entity1067 ) @entity1 by using noninvasive tools. METHODS: One hundred and twenty seven @entity1067 @entity1 who had undergone TURP or @entity12468 between January 2005 and May 2009 were evaluated. They were divided into 2 groups: the postoperative initial peak urinary flow rate (Qmax) was less than 10 mL/sec (Group 1; n=37, TURP=11, @entity12468 =26) and more than 10 mL/sec (Group 2; n=90, TURP=41, @entity12468 =49). We confirmed the @entity1 ' preoperative check lists. The check list were the international prostate symptom score (IPSS), the quality of life score, a past history of acute urinary retention (AUR), body mass index and/or @entity4658 , the serum prostate-specific antigen (PSA) level and the prostate volume, the prostate transitional zone volume and @entity1069 . The initial Qmax was measured at the outpatient clinic one week after discharge. RESULTS: The improvement rate was not significant difference between the TURP group (78.8%) and the @entity12468 group (65.3%). The efficacy parameters were the IPSS-storage symptom score, the prostate volume, the PSA level and a past history of AUR. The IPSS-storage symptom scores of Group 1 (12.3  3.3) was higher than those of Group 2 (10.5  1.7). The prostate volume of Group 2 (42.3  16.6 g) was bigger than that of Group 1 (36.6  7.8 g). The PSA level of Group 2 (3.8  2.6 ng/mL) was higher than that of Group 1 (2.6  2.6 ng/mL). A past history of AUR in Group 1 (35.1%) was more prevalent than that of Group 2 (15.6%). CONCLUSIONS: The non-invasive factors affecting the initial Qmax after TURP or @entity12468 were the IPSS-storage symptom score, the prostate volume and a past history of AUR. Accordingly, in @entity1 who have a higher IPSS-storage symptom score, a smaller prostate volume and a history of AUR, there might be a detrimental effect on the initial Qmax after TURP or @entity12468 . These factors might also be used as long-term prognostic factors.
