良性前列腺增生并发急性尿潴留相关因素探讨

Evaluation of Correlations Associated Factors with Acute Urinary Retention in Benign Prostate Hyperplasia

目的:探讨年龄、病史、前列腺体积及其突入膀胱长度与良性前列腺增生(BPH)并发急性尿潴留(AUR)的关系。方法:回顾性分析123例BPH并发AUR及137例BPH未并发AUR患者的相关资料。结果:BPH并发AUR组患者年龄(73·30±9·59)岁,病史(6·40±4·84)年,前列腺体积(58·18±36·66)ml,前列腺突入膀胱(2·56±1·72)cm;BPH未并发AUR组患者年龄(72·04±9·19)岁,病史(6·35±3·93)年,前列腺体积(43·51±23·45)ml,前列腺突入膀胱(2·14±1·61)cm。两组间前列腺体积和前列腺突入膀胱长度差异均有显著性(P<0·05)。两个不同前列腺体积范围(小于和大于或等于30ml)及两个不同前列腺突入膀胱长度范围(小于或等于和大于2cm)AUR发生率进行比较,差异有显著性(P<0·05)。BPH并发AUR组患者前列腺体积与中叶增生突入膀胱长度(r=0·513,P<0·01)呈显著正相关,与年龄呈正相关(r=0·202,P<0·05)。结论:前列腺体积和前列腺突入膀胱长度可作为前列腺增生症患者并发AUR的临床预测指标。

Objective To evaluate correlations associated factors with acute urinary retention in benign prostate hyperplasia.Methods 260 cases of men （aged older than 48 years） with benign prostate hyperplasia （BPH） were analyzed retrospectively, and patients with prostatic cancer were excluded. The age, the course of BPH and acute urinary retention were recorded, and the length of intravesical prostatic protrusion and prostate volume were measured by transabdominal ultrasonography. These variables were then correlated with the results from AUR of BPH study. There were 123 cases of benign prostate hyperplasia with acute urinary retention and 137 cases without acute urinary retention. Results In the group of acute urinary retention, the mean age of thepatients was （73.30 ± 9.59） years, the mean course of BPH was （6.40 ± 4.84） years, the mean prostatic volume was （58.18 ± 36.66） ml, the mean the length of intravesical prostatic protrusion （2.56 ± 1.72） cm; In the group of without acute urinary retention, the mean age of the patients was （72.04 ±9.19） years, the mean course of BPH was （6.35±3.93）, the mean prostate volume was （43.51 ± 23.45） ml, the mean the length of intravesical prostatic protrusion （2.14 ± 1.61） cm. There were statistically significant differences between the two groups in prostate volume and the length of intravesical prostatic protrusion. The difference in incidence of AUR between prostate volume smaller than 30ml and larger than （or equal to ） 30ml, and the length of intravesical prostatic protrusion shorter than （or equal to ） 2cm and longer than 2cm were significant （ P 〈 0.05） . In the group of acute urinary retention there were statistically significant correlations between prostate volume and the length of intravesical prostatic protrusion, age. In the benign prostatic hyperplasia with acute urinary retention patients, prostate volume was positively correlated to the length of intravesical prostatic protrusion and the age. while there was no obvious correlation between the course of BPH and prostate volume, the length of intravesical prostatic protrusion and the age.Conclusions Larger prostate volume, longer intravesical prostatic protrusion and elder men were susceptible to acute urinary retention in benign prostate hyperplasia. Prostate volume and intravesical prostatic protrusion can be served as clinical predictors for AUR in men with BPH.
