Acute urinary retention predominantly affects men, often due to bladder outlet obstruction (BOO). Most patients recover urinary function after treatment, with clean intermittent catheterization (CIC) used for non-obstructive causes.
Area of Science:
- Urology
- Clinical Medicine
- Medical Research
Context:
- Acute urinary retention (AUR) is a common urological emergency.
- Understanding the demographics, causes, and treatment outcomes of AUR is crucial for patient management.
- This study analyzes a 12-year period of AUR cases at a university hospital.
Purpose:
- To investigate the clinical characteristics, causes, treatments, and outcomes of acute urinary retention.
- To identify demographic trends and etiological factors contributing to AUR.
- To evaluate the effectiveness of various treatment modalities for AUR.
Summary:
- The study reviewed 206 cases of AUR, with 85% being male and 15% female.
- Bladder outlet obstruction (BOO), particularly benign prostatic hyperplasia (BPH), was the primary cause in men (70.3%), while detrusor weakness (DW) was more common in women (64.5%).
- Overall, 67.5% of patients regained spontaneous urination post-treatment, with surgery for BOO and clean intermittent catheterization (CIC) for DW being key interventions.
Impact:
- Findings highlight the male predominance and common causes of AUR, guiding clinical suspicion and diagnostic approaches.
- The study underscores the importance of addressing the underlying cause for successful treatment and recovery of urinary function.
- Results provide insights into treatment strategies, including surgical and conservative methods, for improving patient outcomes in AUR.
