Management of stones in renal transplant

Area of Science:

• Nephrology
• Transplant Surgery
• Urology

Background:

• Kidney stones are increasingly detected in donor organs, leading to potential complications in transplant recipients.
• Both donor-gifted and de-novo kidney stones can manifest in renal transplant recipients.
• Effective management strategies are essential for addressing renal transplant stones.

Purpose of the Study:

• To review current treatment modalities for kidney stones in renal transplant recipients.
• To discuss the timing and methods for managing stones in donors and recipients.
• To highlight the importance of early detection and follow-up.

Main Methods:

• Review of existing literature on renal transplant stones and their management.
• Description of treatment options including conservative management, extracorporeal shockwave lithotripsy, percutaneous nephrolithotomy, ureteroscopy, and open surgery.
• Discussion of ex-vivo techniques for stone removal prior to transplantation.

Main Results:

• Kidney stones can be managed in living donors before transplantation, at the time of transplantation, or in recipients post-transplant.
• Ex-vivo ureteroscopy or pyeloscopy offers a safe method for stone clearance before transplantation, particularly beneficial for living donors.
• A range of surgical and non-surgical interventions are available, tailored to stone size and location.

Conclusions:

• Renal transplant lithiasis has multifactorial causes, necessitating further research into de-novo stone formation.
• Early identification and removal of donor-gifted stones during transplantation improve outcomes.
• Close monitoring of both living donors and transplant recipients is vital for ensuring long-term safety and preventing stone recurrence.
