Abstract Objective: To prospectively compare the outcome of standard minipercutaneous
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 stonefree
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. |
