Objective:
To prospectively compare the outcome of standard mini-percutaneous nephrolithotomy (SmPCNL) versus tubeless mini-percutaneous nephrolithotomy (TmPCNL) as primary treatments of renal stones.
Patients And Methods:
In all, 80 patients with a solitary radio-opaque renal stone and candidates for PCNL were selected. The patients were randomly divided into two groups of 40, one group treated with SmPCNL and the other with TmPCNL. Patients and stone characters, as well as operative and postoperative data of both groups were compared and statistically analysed.
Results:
There was no significant difference between the two groups for patient demographics and stone characteristics. There was no statistically significant difference between the two groups for the mean operative time, mean postoperative drop in haemoglobin, mean postoperative urine leakage, mean hospital stay, and stone-free rate. The mean (SD) postoperative dose of analgesia was statistically significantly higher in the SmPCNL group compared with the TmPCNL group, at 112.5 (48.03) versus 48.8 (43.5) mg, respectively.
Conclusion:
Both procedures are safe and effective for managing renal stones, without any significant difference between the two procedures; however, the postoperative analgesic requirement is significantly higher in SmPCNL.
