Comparison of RLP and PCNL for large pelvis calculi with CKD.

To compare the effect and safety of retroperitoneal laparoscopic pyelolithotomy (RLP) and percutaneous nephrolithotomy (PCNL) for large pelvis calculi with chronic kidney disease (CKD). Between June 2017 and July 2021, 62 patients with CKD and large renal pelvis calculi (>4 cm Significantly longer operation time (101.47 ± 9.25 vs 62.55 ± 7.54 min), less drop in hemoglobin level (0.90 ± 0.38 vs 2.13 ± 0.80 g/dl), staged operations (0% vs 12.9%), postoperative fever (3.23% vs 16.13%) and delayed bowel movement (3.23% vs 14.52), and shorter hospitalization time (3.90 ± 1.66 vs 4.72 ± 1.80 days) were observed in the RLP group ( Although associated with a longer operation time, RLP is a safer and more efficient surgical option for CKD patients with large pelvic stones than PCNL.
