Balancing technology and resources: Is robotic pyeloplasty always necessary?

Introduction: Ureteropelvic junction obstruction (UPJO) hinders urine flow from the renal pelvis to the ureter, causing renal dysfunction. Treatment focuses on relieving obstruction to restore urinary drainage and preserve renal function. Robotic-assisted laparoscopic pyeloplasty (RALP) offers enhanced precision compared to laparoscopic pyeloplasty (LP), but limited comparative data exist for adult patients. This study compares RALP and LP outcomes in an adult cohort from a tertiary care centre. Material and Results: The study included 128 patients (87 RALP, 41 LP). Operative time was significantly longer for RALP (200.92 ±59.26 minutes) vs LP (161.92 ±55.21 minutes, p <0.001), largely due to robotic docking. Both groups had similar EBL (47.87 ml for RALP vs 45 ml for LP, p = 0.45) and success rates (97.7% for RALP vs 97.4% for LP). However, RALP patients experienced a longer LOS (3.91 days vs 3.41 days, p = 0.001). Conclusions: RALP demonstrates technical advantages but does not reduce operative time and incurs increased resource utilisation compared to LP. Both techniques achieve high success rates, though further research is needed to assess RALP's cost-effectiveness.
