The aim of this study is to present our initial experience with intracorporeal pneumatic ureterolithotripsy highlighting the pattern of patients' clinical presentation, techniques, and limitation of the procedure.

Materials and Methods:

This is a retrospective study of cases of ureteric stones managed over a period of 18 months in a private hospital. Data obtained include patients' sociodemography, clinical presentation, stone burden, procedural technique, complication, and need for a secondary procedure. Data were analyzed using the Statistical Package for the Social Sciences version 21.


The total number of patients managed was 20 with an age range of 28-75 years and a mean of 48.2 ± 12.4 years. Majority of them, i.e., 11 (55%) were middle aged. Female gender was more predominant, 11 (55%). Flank pain was the most common mode of presentation. Right-sided stone occurred in 9 (45%), left sided in 7 (35%), and bilateral in 4 (20%). Stone location was in the upper ureter in 4 (16.7%), mid-ureter in 7 (29.2%), and lower ureter in 13 (54.2%). The stone size ranged from 6 to 18 mm with a mean of 9.7 ± 2.5 mm. Four patients (20%) required initial bilateral ureteric stenting before definitive procedure to allow for recovery from sepsis and/or nephropathy. All patients had double-J stenting and were discharged 2 days after the procedure. The procedure was successful in 19 (95%) with 100% stone clearance rate and complete resolution of symptom without any complication. One patient (5%) had a very hard upper ureteric stone which retropulsed into the renal pelvis requiring open nephrolithotomy.


Endoscopic treatment of ureteric stone with intracorporeal pneumatic lithotripsy is a safe and effective treatment modality. It is, however, limited in the management of hard upper ureteric stone, especially those that are close to the pelviureteric junction due to the risk of retropulsion of the stone into the kidney.
