Outcomes of ureteroscopy in Assiut University Hospital : a prospective study

Abstract EN

Context Recent technological advances have led to the expansion of indications and success of ureteroscopy (URS) for stone disease, while decreasing complication rates.

Aims The aim was to evaluate the outcomes of URS for treatment of ureteral stones in our hospital.

Settings and design This was a descriptive case series.

Materials and methods Patients included were adults with ureteral stone(s) managed by URS.

Perioperative together with long‑term postoperative data were analyzed.

Follow‑up extended for 12 months.

Statistical analysis Data analysis was done using SPSS version 19.

2 and Fisher exact tests were used to compare between qualitative variables.

Mann–Whitney test was used to compare between two quantitative variables.

Multiple logistic regression analysis was done to measure the risk factors.

P value was considered statistically significant when less than 0.05.

Results During the period from May 2015 to August 2016, 251 adult patients underwent 263 ureteroscopies for treatment of 304 ureteral stones.

The mean total stone burden was 12.8 ± 5.9 mm.

Treatment of bilateral and ipsilateral multiple stones was performed in 12 and 34 cases, respectively.

Impacted stone(s) were treated in 49 (18.6%) procedures.

The mean operative time was 54.8 ± 22.68 min.

Initial and final stone‑free rates were 83.3 and 100%, respectively.

The overall complications rate was 28.1 %, including mucosal injury (n = 20, 7.6%), false passage (n = 25, 9.1 %), perforation (n = 7, 3.8 %), and stricture (n = 4, 1.5%).

Multivariable analysis revealed that impacted stones had a significant association with intraoperative complications.

Conclusion URS is a safe and effective procedure for treatment of ureteral stones.

However, impacted stones are associated with significantly higher complications rate.
