Risk factors for bladder spasms in elderly patients after minimally invasive surgery of the lower urinary tract / 中华老年医学杂志

ABSTRACT

Objective:To investigate the risk factors for bladder spasms in elderly patients after minimally invasive surgery of the lower urinary tract.Methods:Clinical data of elderly patients from 87 medical centers across the country who had received minimally invasive surgery of the bladder, prostate, or urethra from July 2016 to September 2016 were retrospectively analyzed.Based on the occurrence of bladder spasms, patients were divided into the spasm group and the control group.General information and clinical data were compared between the two groups, and potential risk factors for bladder spasms after surgery were analyzed.Results:A total of 1275 patients were enrolled, aged from 65 to 96 years, with an average age of(73.4±6.1). Bladder spasms occurred in 606(47.5%)of all patients.Univariate analysis showed that, compared with the control group, patients in the spasm group had statistically significant differences in gender, age, constipation, preoperative use of drugs, and surgical site(all P<0.05), while there were no significant differences between the two groups in ethnicity, body mass index(BMI), smoking, drinking, caffeine intake, and marital status(all P>0.05). Logistic regression analysis showed that advanced age( OR=1.310, P=0.007), male( OR=0.595, P=0.030), preoperative use of drugs( OR=0.510, P=0.002)affecting bladder function, and constipation( OR=0.627, P<0.001)were independent influencing factors for bladder spasms in elderly patients after minimally invasive surgery of the lower urinary tract( P<0.05). Conclusions:Old age, male, preoperative use of drugs affecting bladder function, and constipation are risk factors for bladder spasms after minimally invasive lower urinary tract surgery in elderly patients.These findings can be used for guiding clinicians to conduct targeted interventions before surgery to prevent bladder spasms.
