Abstract

Background: Urolithiasis is a common worldwide health problem. Many endosurgical treatments became available for urinary calculi.

Objectives: To find out the success clearance and complication rates of ureteric stone treatment using semi-rigid ureteroscopy and Holmium:YAG laser lithotripsy as a day case procedure.

Methods: In the period from April 2011 to October 2013, a total of 64 patients who were treated by laser lithotripsy were reviewed retrospectively using Fedail Hospital data. Diagnosis was radiologically confirmed. Semi-rigid ureteroscopy and Holmium:YAG laser lithotripsy was conducted as a day case surgery. Operative details, clearance of stone fragments, failure and complications were analysed. Cases were followed clinically and radiologically after one week and one month.

Results: The studied cases were 47 males and 17 females with average age of 47.3 years and ASA I in 52(81.3%). Those who had left ureteric stones were 28(43.8%) patients, only one patient had bilateral stones and 60(93.8%) patients had single stones. The largest stone diameter was 1.9cm. 68.8% had distal ureteric stones, 14.1% had mid third stones, and 17.2% had upper third stones. Most cases 96.9% were operated under spinal anaesthesia with mean operation time 61.2 minutes. Seven patients needed VUJ balloon dilatation to get access to the ureter.20 watt Holmium:YAG laser fibres were used for stone disintegration. 92.2% of cases had uncomplicated clearance, 3.1% minor complications and 4.7% failure of the procedure.100% clearance was confirmed during follow up. 

Conclusion: Semi-rigid ureteroscopy and Holmium:YAG laser lithotripsy is a safe treatment for ureteric calculi and can be conducted as a day case with high success rate and very low morbidity.

Key words: ureteric stone, Semi-rigid ureteroscopy, Holmium:YAG laser lithotripsy.
