通过对61例老年良性前列腺增生症（BPH）伴上尿路结石并积水和19例无BPH而有上尿路结石的患者在ESWL治疗中的B超资料,以及16例BPH并上尿路积水而行开放手术患者的临床资料进行分析,发现上尿路积水的形成,除因膀胱内压增高或不稳定膀胱外,还因增大的前列腺直接压迫输尿管下段和其开口,并使输尿管下段弯曲角度加大变锐,输尿管膀胱壁段斜行部分延长所致。在治疗BPH症时,除纠正排尿困难外,还应注意纠正前列腺对输尿管末段的压迫和折曲影响。
Through the 61 cases of benign prostatic hyperplasia (BPH) associated with urinary tract stones and water and 19 cases of upper urinary tract stones without BPH in ESWL treatment of B-data, and 16 cases of upper urinary tract and BPH Hydrocephalus and open surgery in patients with clinical data analysis and found that the formation of upper urinary tract hydronephrosis, in addition to bladder pressure due to increased or unstable bladder, but also because of the enlarged prostate direct compression of the lower ureter and its opening, and Ureteral lower bending angle increases sharp, ureteral wall segment due to oblique extension. In the treatment of BPH disease, in addition to correcting dysuria, but also pay attention to correct the prostate on the distal ureteral compression and flexion.
