Abstract

Background

Degenerative lumbar spinal stenosis (LSS) is a condition with compression of the dural sac at one or more lumbar levels. Studies investigating whether LSS may affect the urinary function are scarce and have traditionally included few patients. The aim of this study was to examine voiding complaints and urinary function before and after surgery for LSS.

Methods

A total of 81 patients undergoing surgery for symptomatic LSS were prospectively enrolled between October 1, 2022, and July 31, 2024, of which 60 patients were included in the final analyses. Patients were evaluated by questionnaire (International Prostate Symptom Score, IPSS), urinary flow (Q_max, ml/s) and residual urinary bladder volume (RUV) (ultrasonographic measurement, ml) at pre- and post-operative controls.

Results

36 patients were males, median age was 69.5 years. Median dural-sac cross sectional area (DSCA) was 41.7 mm² and 53/59 (89.8 %) patients had Schizas grade C or D indicating significant lumbar stenosis. Median pre-operative scores for urinary symptoms were IPSS 11.0, uroflowmetry 14.3 ml/s and RUV 59.5 ml. Post-operatively, median values of IPSS were 9.0, uroflowmetry 13.8 ml/s and RUV 69.0 ml. There were no statistically significant differences between pre- and post-operative results for neither men nor women. A pre-operative RUV > 100 ml was noted in 21/60 (35.0 %) patients.

Conclusion

Urinary complaints were common in this cohort of surgically treated lumbar spinal stenosis. Decompressive surgery did not significantly alter the results of IPSS, uroflowmetry or RUV. Approximately one third of the patients had a RUV > 100 ml pre-operatively.

腰椎管狭窄手术患者的泌尿系统不适及排尿功能

背景退行性腰椎管狭窄症（LSS）是一种硬脑膜囊在一个或多个腰椎水平受压的疾病。关于LSS是否会影响泌尿功能的研究很少，而且传统上只包括很少的患者。本研究的目的是检查LSS手术前后的排尿投诉和泌尿功能。方法前瞻性纳入2022年10月1日至2024年7月31日期间接受手术治疗的81例症状性LSS患者，其中60例纳入最终分析。采用问卷（国际前列腺症状评分，IPSS）、尿流量（Qmax, ml/s）和剩余膀胱体积（RUV，超声测量，ml）对患者进行术前和术后对照评估。结果男性36例，中位年龄69.5岁。硬膜囊中位横截面积（DSCA）为41.7 mm2, 53/59（89.8% %）患者为Schizas C级或D级，表明明显的腰椎管狭窄。术前泌尿系统症状的中位评分为IPSS 11.0，尿流仪14.3 ml/s, RUV 59.5 ml。术后IPSS中位值9.0，尿流仪中位值13.8 ml/s， RUV中位值69.0 ml。无论男性还是女性，术前和术后结果都没有统计学上的显著差异。21/60（35.0 %）患者术前RUV >； 100 ml。结论：泌尿系统疾病在手术治疗的腰椎管狭窄患者中很常见。减压手术对IPSS、尿流仪或RUV的结果没有显著影响。大约三分之一的患者术前RUV >； 100 ml。
