Polyglycolic acid versus chromic catgut in bladder surgery.

Area of Science:

• Urology
• Surgical Materials Science

Background:

• Sutures used in bladder surgery can potentially lead to calcified deposits and bladder stone formation.
• Assessing the risk associated with different suture materials is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the clinical significance of calcified deposits on sutures in bladder surgery.
• To compare the risk of bladder stone formation between chromic catgut and polyglycolic acid sutures.

Main Methods:

• A blind paired randomized trial comparing 3/0 chromic catgut versus polyglycolic acid 3/0 sutures.
• Cystoscopy with photographic recording at 8 weeks post-operation in patients with and without a history of bladder stones.

Main Results:

• No visible calcified deposits were observed on sutures in any patient at the 8-week follow-up.
• Sutures were only visible in one patient from each group without a history of bladder stones.

Conclusions:

• Neither chromic catgut nor polyglycolic acid sutures pose a significant risk for bladder stone formation.
• The presence or absence of infection does not appear to influence this risk.
