Clinical feature analysis of premenopausal and postmenopausal female adults with kidney stones / 中华泌尿外科杂志

ABSTRACT

Objective To analyze clinical characteristics of premenopausal and postmenopausal female patients with kidney stones.Methods The clinical data of 1 194 female adults with kidney stones from December 2004 to December 2014 were analyzed retrospectively.The incidence of kidney stones in different age groups was analyzed firstly.The post-hysterectomy patients or those taking estrogen for breast cancer were excluded, and then 1 166 patients were enrolled.The patients were divided into premenopausal group (464 cases, 39.8％) and postmenopausal group (702 cases, 60.2％), and clinic features of different groups were evaluated.Results The peak age of female patients with kidney stones is between 50 and 59 years old.There were 105 (22.6％) patients in premenopausal group and 204 (29.1％) patients in postmenopausal group complicated with urinary infection.Fifty-eight (12.5％) patients had genitonrinary malformations such as horseshoe kidney, medullary sponge kidney, ectopic kidney, duplex kidney or pyeloplasty for ureteropelvic junction (UPJ) stricture in premenopausal group, as well as 36 (5.1％) in postmenopausal group.Twenty patients (4.3％) had renal insufficiency in premenopausal group, and 66 (9.4％) in postmenopausal group.These differences were statistically significant (P ＜ 0.05).The patients complicated with hydronephrosis (251 vs.346) and ureteral calculi (63 vs.110) of two groups were not significant different (P ＞ 0.05).Multiple factors Logistic analysis indicated that age and urinary infection were statistically significant factors in the occurrence of renal insufficiency (OR =1.037,1.772, P ＜ 0.05).Conclusions The occurrence of genitourinary malformations was higher among premenopausal female patients with kidney stones, while urinary infection and renal insufficiency were more common for postmenopausal patients.Age and urinary infection were the independent factors for the occurrence of renal insufficiency.
