Context:
Recent technological advances have led to expansion of indications and success of ureteroscopy for stone disease, while decreasing complication rates.
Aims:
To evaluate outcomes of ureteroscopy for treatment if ureteral stones in our hospital.
Settings and Design:
Descriptive case-series.
Materials and Methods:
Patients included were adults with ureteral stone(s) managed by ureteroscopy. 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. Chi-square 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 < 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 mm (SD: ±5.9). Treatment of bilateral and multiple stones was performed in 12 & 34 cases, respectively. Impacted stones were treated in 49 (18.6%) procedures. The mean operative time was 54.8 minutes (SD: ± 22.68). 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.
Conclusions:
Ureteroscopy is a safe and effective procedure for treatment of ureteral stones less than 2cm. However, impacted stones are associated with significantly higher complications rate.
