A retrospective study of minipercutaneous laser lithotripsy for treatment of allograft kidney lithiasis obstruction.

OBJECTIVE: To evaluate the safety and effectiveness of invasive percutaneous laser lithotripsy to manage allograft kidney lithiasis obstruction. METHODS: We treated 11 patients with kidney allograft lithiasis with minimally invasive percutaneous nephrolithotomy (mPCNL). RESULTS: All patients treated by mPCNL showed no residual stones thereafter. All subjects recovered successfully without major complications with improved renal function and reduced serum creatinine values. CONCLUSION: mPCNL was safe and effective to treat kidney allograft lithiasis obstruction. We suggest that it may be considered to be a first-line option for this condition.
