Summary
Polyglactin (Vicryl) sutures used in pyeloplasty may lead to renal pelvis stone formation. Endoscopic procedures are recommended for stone removal and suture remnant management.
Area of Science:
- Urology
- Nephrology
- Surgical Materials Science
Background:
- Pyeloplasty is a common surgical procedure to correct ureteropelvic junction obstruction.
- Suture materials play a critical role in surgical outcomes and potential complications.
Observation:
- Two patients developed renal pelvis stones 2 and 5 years post-pyeloplasty.
- No ureteropelvic junction obstruction was detected in either case.
Findings:
- Polyglactin (Vicryl) suture material used in the renal pelvis closure is suspected as the cause of stone formation.
- The presence of suture remnants may act as a nidus for calculi development.
Implications:
- Consider alternative suture materials or techniques in pyeloplasty to minimize stone formation risk.
- Endoscopic stone removal offers a minimally invasive approach for treatment and allows for assessment of suture remnants and the pyeloureteral junction.
