Rapid versus gradual bladder decompression in acute urinary retention

Area of Science:

• Urology
• Surgical Outcomes

Background:

• Acute urinary retention (AUR) is a common urological emergency.
• Benign prostatic hyperplasia (BPH) is a frequent cause of AUR.
• Bladder decompression methods vary, with potential for adverse events.

Purpose of the Study:

• To compare adverse events between gradual and rapid bladder decompression in AUR patients.
• To assess the incidence of hypotension and hematuria with different drainage methods.

Main Methods:

• A case-control study involving 62 patients with AUR due to BPH.
• Patients were divided into rapid drainage and gradual drainage groups.
• Gradual drainage involved evacuating 100 mL immediately, followed by 2-hour slow drainage.

Main Results:

• No significant difference in adverse events between groups.
• Mild hematuria occurred in 2 patients (rapid drainage group), none in the gradual group.
• Blood pressure decreased slightly in both groups, without significant hypotension.

Conclusions:

• Gradual bladder decompression offers no significant advantage over rapid decompression for AUR.
• Adverse events like hematuria and hypotension are uncommon and typically mild with rapid decompression.
