Abstract:
Objective To evaluate the efficacy and safety of external ureteral catheterization of tubeless mini-percutaneous nephrolithotomy(mini-PCNL)in the treatment of single urinary calculus.Methods Clinical data of 21 patients with single renal or upper ureteral calculi treated with tubeless mini-PCNL from June 2021 to December 2022 were retrospectively analyzed.Among them,there were16 cases of kidney stones and5 cases of upper ureteral stones.The length of stones was1.5-3.5 cm(mean,2.07±0.56 cm).The ureteral catheter was indwelled by cystoscope and retained for catheterization,and the ureteral catheter and catheterization were fixed.If there were no residual stones after mini-PCNL,the Peel-away sheath was removed and the incision was sutured.Results All the operations were successfully completed,and the catheterization and ureteral catheter were removed 3-5 days after operation.There were slight gross hematuria in all the cases,fever in 3 cases,perirenal hematoma in 4 cases,and no urinary extravasation postoperatively.One month after discharge,B-ultrasonography or CT scanning showed no lithiasis,urinary cyst or hematoma formation around the kidney.Conclusion In selected cases(single and non-staghorn stones,without intraoperative stone residue or ureteral stenosis),external ureteral catheterization of tubeless mini-PCNL is safe and effective.
