Results
The mean age of the patients in LSE and control groups was 45.0±15.6
(median 45) and 42.5±18.7 (median 44), respectively and there was no
statistically significant difference between the two groups (p=0.71). In
addition, we did not find statistical significance between the two
groups in terms of gender, side, previous history of failed SWL for same
stone, maximum stone diameter, stone density, stone locations, and
preoperative double J stent placement rates (p=0.77, p=0.37, p=0.77,
p=0.21, p=0.72, p=0.29, and p=0.76, respectively). (Table 2)
Mean operation and fluoroscopy times were statistically indifferent to
both groups (p=0.12, p=0.58 respectively). Stone free status of groups
was similar (88% in LSE and 79% in the control group; p=0.33). There
was no difference in complication rates between the two groups also
(17% vs 13%, p=0.9). (Table 3)
Mild bleeding was observed in one patient in the LSE group, and minimal
mucosal injury was observed in one patient in both groups
perioperatively. Ureteral access could not be provided in one LSE
patient and SWL was planned for a different session. Mucosal injury
requiring stent insertion occurred in one patient from the control
group. Two patients had fewer (one in LSE group which is requiring
antipyretics and one in the control group which is requiring
antibiotics). One patient had acute urine retention after double J stent
removal (as Grade 2 complication in the control group). One patient
developing renal colic for ureteral residual stone fragment underwent
ureterorenoscopy (as Grade 3 complication in LSE group). All
complications presented in Table 4 according to modified Satava and
Clavien Classifications.
Fifty-four % (13/24) of LSE operations were performed by guest
surgeons. It was the first time working with the staff in the OR for
these surgeons. Perioperative and postoperative outcomes of the LSE
group according to surgeons status are shown in Table 5. No
statistically significant difference was found between the two groups in
any parameter.
