چکیده (انگلیسی):

Objective: This study was conducted to evaluate clinical experience and
learning curve associated with laparoscopic ureterolithotomy performed for upper ureteral
stones.
Materials and methods: The medical data of 50 patients who had undergone retroperitoneal
laparoscopic ureterolithotomy between June 2010 and March 2013 were retrospectively
analyzed. To assess the learning curve, patients were divided into two groups: Group A
(the first 25 cases) and Group B (the last 25 cases). In Group A, double J stents were placed
in 17 patients, whereas in Group B 15 patients received double J stents. In Group A, three
ports were placed in nine patients and four ports in 16 patients. In Group B, three ports were
placed in 20 patients and five patients had four ports. The patients were compared according
to demographics, operative time, stone size, complications, hospital stay, and
transfusion.
Results: The mean age for Group A was 47.8
14.13 (21e72) years and that for Group B was
44.2
14.98 (22e78) years. Mean operative times were 106.4
38 (55e210) minutes and
70.76
30.4 (30e180) minutes for Groups A and B, respectively (p < 0.05). The mean hospital
stay was 7.12
4.47 (3e22) days and 4.04
2.05 (2e12) days for Groups A and B,
respectively (p < 0.05). The mean stone size was 20.12
5.18 (12 e30) mm and
19.44
4.44 (13e28) mm for Groups A and B, respectively (p > 0.05). Conclusion: In our study, as staff experience (in performing laparoscopic retroperitoneal ureterolithotomy)
increased, operative time, length of hospital stay, and complication rates
have correspondingly declined.
