RESULTS
The mean age of the patients was 47±15 (12-81) years. Of the patients,
86 were male and 68 were female. Mean stone size was 17.1±8 (7-40) mm
and mean operative time was 56±23 (30-120) minutes.
For analysis of ureteral injury, overall 79.9% of patients had evidence
of injury to the ureter wall. Non-significant lesion (grade 0) was seen
in 39% of patients. Grade 1 lesions were assigned in 40.9% of
patients. No grade 2 and higher lesions were detected. In postoperative
period a total of 5 patients (3.2%) had Clavien I and II complications,
including hematuria and fever. Grade IV complication developed in 3
patients (1.9%) (Sepsis requiring intermediate care/intensive care unit
management).
After follow-up period, no ureteral stricture was detected in the
patients at first year control.
Immediate stone-free rate was achieved in 118 (76.6%) patients in the
first session. After first session, 30 patients underwent second RIRS
session. Overall stone free rates was 90.3% (n=139). (Table 2)
