Objective: To assess the feasibility and indications of tubeless percutaneous nephrolithotomy (PCNL) in the treatment of complicated renal calculi. Methods: Forty cases undergoing tubeless PCNL and another 32 receiving conventional PCNL were included from May 2016 to July 2018. Then the pre-and postoperative indexes of the two groups were compared. Results: The difference was insignificant between the two groups in terms of the operative time, duration of macroscopic haematuria, decrease of Hb, and rate of blood transfusion, residual calculus, hydroperinephrosis and perirenal hematoma. However, patients treated with tubeless PCNL had superiority over those undergoing conventional PCNL in off-bed time, postoperative hospital stay, hospital cost, VAS on the first day after operation, rate of using painkillers, incidence of urinary extravasation and infection. Conclusion: For complicated renal calculi such as heavy load, severe hydronephrosis and staghorn calculi, tubeless PCNL is equally safe and feasible, and has some advantages. The indications can be relaxed appropriately. |
