Objective: This study aimed to determine the effectiveness of extracorporeal Shock Wave Lithotripsy and retrograde Intrarenal Surgery on obtaining stone-free status for renal pelvic stones measuring 1-2 cm in diameter.
Material & Methods: This quasi-experimental study was conducted at the Department of Urology, Khyber Teaching Hospital, Peshawar, where a total of 60 patients with renal pelvic stones measuring 1–2 cm were randomly assigned to two equal groups: ESWL (n = 30) and RIRS (n = 30). Stone clearance was assessed on the 7th postoperative day using ultrasound and X-ray KUB.
Results: The mean age of participants in Group A (ESWL) increased to 41 years (SD = 10.67), while the mean in Group B (RIRS) increased to 42 years (SD = 9.09). For Group A (ESWL), the sample included 20 males and 10 females, representing 67% and 33%, respectively. For Group B (RIRS), 21 participants were males, and 9 were females, accounting for 70% and 30%, respectively. The Chi-square test results indicate no statistically significant difference between the two groups regarding gender ratio (p = 0.7813). The data indicated that the patients with renal pelvic stones of 1–2 cm were more likely to be stone-free after retrograde intrarenal surgery (RIRS) than after extracorporeal shock wave lithotripsy (ESWL). In the RIRS group, 73% were stone-free, while only 33% were stone-free in the ESWL group (p = 0.0019).
Conclusion: The study finds that RIRS is more effective than ESWL for managing 1-2cm renal pelvic stones. RIRS achieves higher stone-free rates, especially when anatomical difficulties and challenges associated with ESWL are common, and it can precisely locate stones and utilize advanced laser treatment features.
