Demographic data
The characteristics of the patients and stones are shown in Table 1. The
median age of the patients was 69 years, and the female/male ratio was
61 (47.3%)/68 (52.7%). While the median stone size was 90 mm, the
median stone density (HU) was found to be 1,039. The most frequent
primary location of the stones was the pelvis (35.6%), followed by
multiple calyceal (20.9%), proximal ureteral (20.1%) and lower
calyceal (15.5%) stones.
The median operation time was 65 minutes. UAS was used in 17.8% of the
patients. While postoperative stents were placed in 77.5% of the
patients, a ureteral catheter was required in 9.3%. After the
operation, residual fragments were detected in 10.8% of the patients
and not present in 69.7%. Seven (5.4%) patients had postoperative
fever, and one (0.7%) developed sepsis.
