Bladder calculi: did the clinical picture change?

Area of Science:

• Urology
• Nephrology
• Stone Disease Management

Background:

• Socioeconomic changes impact urinary stone presentation, including bladder calculi.
• Contemporary data on bladder calculi clinical pictures are limited.
• Understanding evolving presentations is crucial for effective management.

Purpose of the Study:

• To analyze the changing clinical presentation of bladder calculi.
• To identify factors associated with specific symptoms like acute urinary retention.
• To provide updated insights into bladder stone disease.

Main Methods:

• Retrospective review of 328 patients undergoing surgical therapy for bladder calculi.
• Data collected from January 1995 to June 2005.
• Analysis of presenting symptoms, patient demographics, and stone characteristics.

Main Results:

• Acute urinary retention was the most common presentation (67%).
• Patients with retention were younger, had more renal colic, and less bladder outlet obstruction.
• Smaller stones (<1 cm) were more frequent in the retention group (72% vs. 39%).
• Calcium oxalate stones were prevalent (78%).

Conclusions:

• Acute urinary retention is the predominant presentation for bladder calculi.
• Younger age, prior renal colic, and smaller stone size increase the likelihood of retention.
• These findings reflect shifts in bladder stone disease characteristics.
