Abstract


Background: Pakistan lies in the Afro-Asia stone belt. Ureteric calculi are common occurrence and a major burden on health care facilities in Pakistan. The objective of this study was to assess the efficacy and safety of pneumatic lithoclast in the management of ureteric calculi. Methods: Case series study Department of Urology at Institute of Kidney Diseases Hayatabad Peshawar, from 1st Oct 2010 to 1st Oct 2011. One-hundred adult patients with ureteric calculi ≥ 0.7 cm were evaluated by history, physical examination, routine blood and urine examination after taking their written informed consent and approval of ethical committee. Ultrasound and X-ray KUB were done with IVU if required. All patients underwent ureteroscopy within intracorporeal lithotripsy and JJ stenting. Patients were followed up with post-op X-ray KUB at 24 hours and then weekly intervals till they became stone free. Following parameters were assessed: stone size, site, laterality, degree of fragmentation, success rate, stone migration and complications. Inability to reach the calculus with URS, proximal migration of stone or requirement of another/auxiliary procedure was considered failure. Results: One hundred and ten patients were enrolled with a mean age of 38±10 years. There were 72 males and 28 females. Fifty-eight calculi were on right and 42 on left side. 24, 24 and 52 stones were in upper, middle and lower ureter respectively. Forty stones measured 7–10 mm, 52 measured 11–15 mm and 8 measured 16–20 mm in size. 98 stones were broken while 2 calculi migrated proximally. Overall success rate was 90% (Efficiency Quotient =78.95). Success rate in upper, middle and lower ureter was 83.3%, 83.3% and 96.1% respectively. 10 and 2 patients required ESWL and open ureterolithotomy, respectively, as additional treatment. Mean operative time was 33.5 minutes. There were no major complications. Conclusions: Pneumatic lithoclast with URS is effective and safe in the management of the ureteric calculi with some limitations in the upper ureter.
